Quinacrine 224-233 polyunsaturated fatty acid lipoxygenase ALOX15 Oryctolagus cuniculus 89-101 1311959-7 1992 The increase in [Ca2+]i elicited by ATP apparently caused the activation of a calmodulin-dependent phospholipase A2 since trifluoperazine, an inhibitor of calmodulin, and quinacrine, an inhibitor of phospholipase A2, prevented the stimulation of PGI2 release by ATP.

Quinacrine 26-36 phospholipase A2 group IB Homo sapiens 75-91 1311688-4 1992 This conclusion is supported by our findings that inhibition of GTPase by mepacrine amplified bradykinin-stimulated Ca2+ influx, but did not interfere with the effect of the Ca2+ ionophore A23187. Quinacrine 74-83 kininogen 1 Homo sapiens 94-104 1311688-5 1992 Similar to its effect on Ca2+ influx, mepacrine also potentiated endothelium-derived relaxing factor (EDRF) formation by bradykinin and sodium fluoride, but did not affect A23187-induced EDRF biosynthesis.

Quinacrine 118-127 phospholipase A2 group IB Homo sapiens 226-242 1662619-4 1991 Three lines of evidence indicate phospholipase A2 activity to be involved in arachidonic acid release: (a) its inhibition by mepacrine, (b) the concomitant generation of lysophosphatidylcholine from [3H]choline-labeled cells and (c) an increase in arachidonic acid release from 14C-labeled phosphatidylcholine in particulate fractions from PMA-treated and bradykinin-treated keratinocytes. Quinacrine 125-134 phospholipase A2, group IB, pancreas Mus musculus 33-49 21043868-7 1992 Furthermore this activation seems to be dependent on arachidonic acid mobilization from platelet phospholipids by phospholipase A(2) since mepacrine is able to block H(2)O(2)-mediated platelet activation.

Quinacrine 72-81 nerve growth factor Rattus norvegicus 115-118 3220836-2 1988 In contrast, such an inhibition was not seen in the rats given DAP from 0 to 4 h; it occurred when quinacrine, a polyamine oxidase inhibitor, was concomitantly dosed, and disappeared with further addition of putrescine. Quinacrine 99-109 polyamine oxidase Rattus norvegicus 113-130 3129942-9 1988 Furthermore, alpha-1 but not beta-1 adrenergic receptor stimulated PG synthesis is inhibited by mepacrine, a phospholipase A2 and C inhibitor. Quinacrine 96-105 adrenoceptor alpha 1D Homo sapiens 13-20 3259847-4 1988 The actions of the endothelium-dependent and -independent vasodilators, ATP and nitroprusside, respectively, were studied before and after administration of quinacrine (an inhibitor of phospholipase A2), which blocks formation and/or release of endothelium-derived relaxing factor (EDRF). Quinacrine 157-167 phospholipase A2 group IB Canis lupus familiaris 185-201 3131280-3 1988 A phospholipase A2 inhibitor, quinacrine (2 X 10(-6) M), also inhibited the TNF cytotoxicity. Quinacrine 30-40 phospholipase A2 group IB Homo sapiens 2-18 3131280-3 1988 A phospholipase A2 inhibitor, quinacrine (2 X 10(-6) M), also inhibited the TNF cytotoxicity. Quinacrine 30-40 tumor necrosis factor Homo sapiens 76-79 2447244-4 1988 The effect of PLA2 was prevented by EGTA and two nonselective PLA2 inhibitors, mepacrine and bromophenacyl bromide. Quinacrine 79-88 phospholipase A2 group IB Rattus norvegicus 14-18 3124931-3 1988 The neuronal responses to IL-1 were blocked or attenuated by concurrent application of mepacrine (a phospholipase inhibitor) or sodium salicylate (a cyclooxygenase inhibitor). Quinacrine 87-96 interleukin 1 alpha Homo sapiens 26-30 2830996-3 1988 All these effects were efficiently inhibited by the PLA2 inhibitor quinacrine. Quinacrine 67-77 phospholipase A2 group IB Rattus norvegicus 52-56 2838694-3 1988 Similar inhibitory effects are observed with mepacrine, an inhibitor of phospholipase A2 (PLA2). Quinacrine 45-54 phospholipase A2 group IB Rattus norvegicus 72-88 2838694-3 1988 Similar inhibitory effects are observed with mepacrine, an inhibitor of phospholipase A2 (PLA2). Quinacrine 45-54 phospholipase A2 group IB Rattus norvegicus 90-94 3068748-3 1988 Mepacrine sharply diminished neutrophil migration, O2 and elastase release. Quinacrine 0-9 immunoglobulin kappa variable 1D-39 Homo sapiens 51-66 3428670-3 1987 Pretreatment with the phospholipase A2 inhibitor, quinacrine, prevented the increases in mucosal phospholipase A2 activity and lysophosphatidylcholine/phosphatidylcholine ratio after ischaemia and morphological examinations revealed that the mucosa was then also protected against ischaemic injury. Quinacrine 50-60 phospholipase A2 group IB Rattus norvegicus 22-38 3428670-3 1987 Pretreatment with the phospholipase A2 inhibitor, quinacrine, prevented the increases in mucosal phospholipase A2 activity and lysophosphatidylcholine/phosphatidylcholine ratio after ischaemia and morphological examinations revealed that the mucosa was then also protected against ischaemic injury. Quinacrine 50-60 phospholipase A2 group IB Rattus norvegicus 97-113 3120519-5 1987 Quinacrine, a non specific inhibitor of phospholipase A2 impaired PAF-acether formation in a dose-dependent manner. Quinacrine 0-10 phospholipase A2 group IB Rattus norvegicus 40-56 3660410-10 1987 Dantrolene and mepacrine antagonized the synergism between halothane and phospholipase A2 most likely by reducing the lytic action of halothane in the presence of arachidonic acid. Quinacrine 15-24 phospholipase A2 group IB Homo sapiens 73-89 3660410-11 1987 The red blood cell is a useful model for studying the antagonism of halothane and phospholipase A2 toxicity by dantrolene and mepacrine. Quinacrine 126-135 phospholipase A2 group IB Homo sapiens 82-98 3112143-5 1987 Treatment of C62B cells with two other glucocorticoids, betamethasone and cortisone, produced results similar to those of dexamethasone as did treatment with quinacrine, a phospholipase A2-selective inhibitor. Quinacrine 158-168 phospholipase A2 group IB Homo sapiens 172-188 3116708-0 1987 The inhibitory action of quinacrine on endotoxin-induced tissue factor expression in cultured human endothelial cells is due to cell injury. Quinacrine 25-35 coagulation factor III, tissue factor Homo sapiens 57-70 3133309-2 1988 In this study, the involvement of arachidonate metabolism has been investigated further with the following results: (i) Cytolysis of human U937 tumour cells by recombinant TNF was reduced by dexamethasone and quinacrine, agents which inhibit phospholipase A2. Quinacrine 209-219 tumor necrosis factor Homo sapiens 172-175 3133309-2 1988 In this study, the involvement of arachidonate metabolism has been investigated further with the following results: (i) Cytolysis of human U937 tumour cells by recombinant TNF was reduced by dexamethasone and quinacrine, agents which inhibit phospholipase A2. Quinacrine 209-219 phospholipase A2 group IB Homo sapiens 242-258 2834949-2 1988 Inhibition of phospholipase A2 with para-bromophenacyl bromide, dexamethasone or quinacrine, alone or in combination, blocked arachidonate release by 50%-60% but had no effect on EDRF production as assessed by cyclic GMP accumulation in mixed- or co-cultures of endothelial and vascular smooth muscle cells. Quinacrine 81-91 LOC104974671 Bos taurus 14-30 2829912-0 1988 Effects of quinacrine on vasopressin-induced changes in glycogen phosphorylase activity, Ca2+ transport and phosphoinositide metabolism in isolated hepatocytes. Quinacrine 11-21 arginine vasopressin Homo sapiens 25-36 2829912-1 1988 In isolated hepatocytes, quinacrine (150-250 microM) inhibited vasopressin-induced increases in glucose release, glycogen phosphorylase a activity and 45Ca2+ efflux; and glucagon-induced increases in glucose release and cyclic AMP formation. Quinacrine 25-35 arginine vasopressin Homo sapiens 63-74 2829912-2 1988 These results indicate that a phospholipase A2 enzyme sensitive to quinacrine is unlikely to be involved in the process by which vasopressin stimulates glycogen phosphorylase activity in the liver cell. Quinacrine 67-77 phospholipase A2 group IB Homo sapiens 30-46 2829912-3 1988 In cells labelled with [3H]inositol, much lower concentrations of quinacrine (20-50 microM) inhibited the stimulation by vasopressin of the accumulation of [3H]inositol. Quinacrine 66-76 arginine vasopressin Homo sapiens 121-132 3335042-1 1988 Mammary carcinogenesis studies were conducted to determine the chemopreventive activity of quinacrine, an antimalarial drug which suppresses the production of arachidonic acid from phospholipid through inhibition of phospholipase A2. Quinacrine 91-101 phospholipase A2 group IB Rattus norvegicus 216-232 3690677-4 1987 PA-2 inhibitors, quinacrine and p-bromophenacyl bromide, inhibited NK CMC at the effector cell level, but affected neither initial target-effector cell binding nor dissociated conjugates during the length of the NK assay, suggesting that they block post-binding lytic events. Quinacrine 17-27 phospholipase A2 group IB Homo sapiens 0-4 2824717-9 1987 Fourth, mepacrine blockade of the Ca2+-dependent enzyme phospholipase A2, which releases endogenous oleate from membrane phospholipids, inhibited the time-course of a persistent LTP response. Quinacrine 8-17 phospholipase A2 group IB Homo sapiens 56-72 3120703-6 1987 A transient appearance of radiolabelled phosphatidic acid and diacylglycerol indicated phosphatidylinositol hydrolysis by phospholipase C. Pretreatment with a phospholipase A2 inhibitor, mepacrine, substantially prevented the antigen-induced liberation of [3H]arachidonic acid from phosphatidylcholine. Quinacrine 187-196 phospholipase A2 group IB Rattus norvegicus 159-175 3660410-0 1987 Dantrolene and mepacrine antagonize the hemolysis of human red blood cells by halothane and bee venom phospholipase A2. Quinacrine 15-24 phospholipase A2 group IB Homo sapiens 102-118 3660410-8 1987 Dantrolene (10 microM) and mepacrine (10 microM) significantly antagonized hemolysis induced by halothane and phospholipase A2 or halothane and exogenously added arachidonic acid and lysophosphatidylcholine. Quinacrine 27-36 phospholipase A2 group IB Homo sapiens 110-126 3119146-3 1987 This effect was inhibited by the protein kinase inhibitor 1-(-5-isoquinolinylsulfonyl)-2-methylpiperizine (IC50 = 25 microM) and the phospholipase A2 inhibitor, mepacrine (IC50 = 5 microM). Quinacrine 161-170 phospholipase A2 group IB Rattus norvegicus 133-149 2887563-10 1987 The effects of norepinephrine, A23187, and protein kinase C activators appear to be mediated by phospholipase A2 because the effects of these compounds on [3H]arachidonic acid release are blocked by an established inhibitor of this enzyme, mepacrine, and because these compounds stimulate the formation of 32P- and 14C-labeled lysophosphatidylcholine by glands incubated with 32Pi or [14C]choline. Quinacrine 240-249 phospholipase A2 group IB Homo sapiens 96-112 3594767-2 1987 These compounds were administered before and after a 30 min intracoronary infusion of the phospholipase A2 inhibitor quinacrine (300 micrograms/min). Quinacrine 117-127 phospholipase A2 group IB Canis lupus familiaris 90-106 3106986-3 1987 Quinacrine at concentrations of 1-5 microM attenuated the magnitude of the PRL stimulation of cell division; at concentrations of 10 microM and above quinacrine abolished the PRL response. Quinacrine 150-160 prolactin Homo sapiens 175-178 3129942-9 1988 Furthermore, alpha-1 but not beta-1 adrenergic receptor stimulated PG synthesis is inhibited by mepacrine, a phospholipase A2 and C inhibitor. Quinacrine 96-105 phospholipase A2 group IB Homo sapiens 109-125 3475493-13 1987 Mepacrine, a phospholipase A2 inhibitor, more potently inhibited the bradykinin- and ATP-induced contractions than the ACh-induced one. Quinacrine 0-9 phospholipase A2 Oryctolagus cuniculus 13-29 3588973-7 1987 Phospholipase A2 activity was inhibited by bromophenacyl bromide, chlorpromazine and mepacrine in decreasing order of effectiveness. Quinacrine 85-94 phospholipase A2 Oryctolagus cuniculus 0-16 3101507-1 1987 Quinacrine either inhibited or stimulated Na-Ca exchange in cardiac sarcolemmal vesicles, depending on the experimental conditions. Quinacrine 0-10 nascent polypeptide associated complex subunit alpha Homo sapiens 42-47 3101507-2 1987 When present in the assay medium for Na-Ca exchange, quinacrine inhibited both Nai-dependent Ca2+ uptake (Ki = 50 microM) and Nao-dependent Ca2+ efflux. Quinacrine 53-63 nascent polypeptide associated complex subunit alpha Homo sapiens 37-42 3101507-5 1987 The inhibitory effects of quinacrine on Na-Ca exchange activity are qualitatively similar to those reported previously for amiloride derivatives. Quinacrine 26-36 nascent polypeptide associated complex subunit alpha Homo sapiens 40-45 3101507-6 1987 When Na-loaded vesicles were preincubated with quinacrine and then assayed for Na-Ca exchange in a quinacrine-free medium, stimulation of exchange activity was observed. Quinacrine 47-57 nascent polypeptide associated complex subunit alpha Homo sapiens 79-84 3101507-6 1987 When Na-loaded vesicles were preincubated with quinacrine and then assayed for Na-Ca exchange in a quinacrine-free medium, stimulation of exchange activity was observed. Quinacrine 99-109 nascent polypeptide associated complex subunit alpha Homo sapiens 79-84 3101507-9 1987 Since Ca2+, quinacrine and tetraphenylphosphonium all bind strongly to sarcolemmal membranes, it is suggested that the observed stimulation of exchange activity involves a local electrostatic effect of the bound cations in accelerating a rate-limiting step in the reaction mechanism for Na-Ca exchange. Quinacrine 12-22 nascent polypeptide associated complex subunit alpha Homo sapiens 287-292 3815542-0 1987 Quinacrine-induced changes in mitotic PtK1 spindle microtubule organization. Quinacrine 0-10 mitogen-activated protein kinase kinase kinase 11 Homo sapiens 38-42 3594487-5 1987 Therefore separation of interleukin-2-incubated cells for LAK activity could be accomplished using sorting after quinacrine staining. Quinacrine 113-123 interleukin 2 Mus musculus 24-37 3815542-1 1987 Quinacrine, an acridine derivative which competitively binds to ATP binding sites, has been used to study the role of ATP requiring molecules in microtubule organization in mitotic PtK1 cells. Quinacrine 0-10 mitogen-activated protein kinase kinase kinase 11 Homo sapiens 181-185 3038761-2 1987 The generation of these lysophosphatidylcholine-like molecules appears to represent an essential step in the activation of the oxidative burst of the PMNL triggered by PMA since inhibition of phospholipase A2 (PLA2) by p-bromophenacylbromide (BB) or mepacrine results in an inhibition of the O-2 release. Quinacrine 250-259 phospholipase A2 group IB Homo sapiens 192-208 3038761-2 1987 The generation of these lysophosphatidylcholine-like molecules appears to represent an essential step in the activation of the oxidative burst of the PMNL triggered by PMA since inhibition of phospholipase A2 (PLA2) by p-bromophenacylbromide (BB) or mepacrine results in an inhibition of the O-2 release. Quinacrine 250-259 phospholipase A2 group IB Homo sapiens 210-214 3102257-2 1986 Mepacrine, a phospholipase A2 inhibitor (3 X 10(-5) M) and the lipoxygenase inhibitor nordihydroguaiaretic acid (10(-5) M) inhibited this response whereas the cyclooxygenase inhibitor, diclofenac sodium (10(-5) M), and the thromboxane synthetase inhibitor imidazole (10(-5) M) did not. Quinacrine 0-9 phospholipase A2 group IB Rattus norvegicus 13-29 3503494-6 1987 The co-existence of PLA2 with its inhibitors--quinacrine (3 microM), cortisone (0.01 microM) and tetracaine (30 microM)--significantly overcame the PLA2-induced inhibition of both indices. Quinacrine 46-56 phospholipase A2, group IB, pancreas Mus musculus 20-24 3503494-6 1987 The co-existence of PLA2 with its inhibitors--quinacrine (3 microM), cortisone (0.01 microM) and tetracaine (30 microM)--significantly overcame the PLA2-induced inhibition of both indices. Quinacrine 46-56 phospholipase A2, group IB, pancreas Mus musculus 148-152 2875734-3 1986 However, the rebound crosslinked ATPase differed from the native enzyme in lacking the ability to restore NADH oxidation - and ATP hydrolysis-dependent quenching of the fluorescence of quinacrine to ATPase-stripped membrane vesicles. Quinacrine 185-195 ATPase Escherichia coli 33-39 3553641-5 1986 PG I2 synthesis by rat aortic ring was inhibited by mepacrine, which inhibits phospholipase A2. Quinacrine 52-61 phospholipase A2 group IB Rattus norvegicus 78-94 2429133-12 1986 But the release was also inhibited by the calmodulin antagonists, W-7 and mepacrine, suggesting that the influx of calcium in the permeabilized cells acts primarily through calmodulin-mediated enzyme activation. Quinacrine 74-83 calmodulin 1 Homo sapiens 42-52 2429133-12 1986 But the release was also inhibited by the calmodulin antagonists, W-7 and mepacrine, suggesting that the influx of calcium in the permeabilized cells acts primarily through calmodulin-mediated enzyme activation. Quinacrine 74-83 calmodulin 1 Homo sapiens 173-183 3106986-3 1987 Quinacrine at concentrations of 1-5 microM attenuated the magnitude of the PRL stimulation of cell division; at concentrations of 10 microM and above quinacrine abolished the PRL response. Quinacrine 0-10 prolactin Homo sapiens 75-78 2875734-3 1986 However, the rebound crosslinked ATPase differed from the native enzyme in lacking the ability to restore NADH oxidation - and ATP hydrolysis-dependent quenching of the fluorescence of quinacrine to ATPase-stripped membrane vesicles. Quinacrine 185-195 ATPase Escherichia coli 199-205 3091592-4 1986 With phorbol diesters as stimuli, the following inhibitors of phospholipase A2 and lipoxygenase suppressed release of H2O2 at nontoxic concentrations (microM range): p-bromophenacyl bromide, quinacrine, eicosatetraenoic acid, nordihydroguaiaretic acid, and phenidone. Quinacrine 191-201 phospholipase A2, group IB, pancreas Mus musculus 62-78 3766758-4 1986 Pretreatment with the phospholipase A2 inhibitor quinacrine reduced the pulmonary vascular responses to ACh without affecting systemic arterial pressure. Quinacrine 49-59 phospholipase A2 Oryctolagus cuniculus 22-38 3756201-6 1986 Indomethacin (500 microM), mepacrine (500 microM) and N-ethylmaleimide (4 mM) inhibited the phospholipase A2 by 69, 62 and 19%, respectively. Quinacrine 27-36 phospholipase A2 group IB Homo sapiens 92-108 3781471-0 1986 Prolactin actions on casein and lipid biosynthesis in mouse and rabbit mammary gland explants are abolished by p-bromphenacyl bromide and quinacrine, phospholipase A2 inhibitors. Quinacrine 138-148 prolactin Mus musculus 0-9 3781471-0 1986 Prolactin actions on casein and lipid biosynthesis in mouse and rabbit mammary gland explants are abolished by p-bromphenacyl bromide and quinacrine, phospholipase A2 inhibitors. Quinacrine 138-148 phospholipase A2 Oryctolagus cuniculus 150-166 3781471-1 1986 p-Bromphenacyl bromide (BPB) at concentrations of 50 microM and above and quinacrine (50 microM) abolished the actions of prolactin (PRL) on casein and lipid biosynthesis in cultured mouse mammary gland explants. Quinacrine 74-84 prolactin Mus musculus 122-131 3781471-3 1986 Since BPB and quinacrine are known to inhibit the enzyme phospholipase A2 (PLA2), it is possible that ongoing PLA2 activity is essential for prolactin to express its actions on at least certain lactogenic processes. Quinacrine 14-24 phospholipase A2, group IB, pancreas Mus musculus 57-73 3781471-3 1986 Since BPB and quinacrine are known to inhibit the enzyme phospholipase A2 (PLA2), it is possible that ongoing PLA2 activity is essential for prolactin to express its actions on at least certain lactogenic processes.

Quinacrine 0-9 tachykinin precursor 1 Homo sapiens 23-34 2413502-7 1985 It seems probable that chloroquine and mepacrine inhibit leukotriene release by inhibition of phospholipase A2 in lung. Quinacrine 39-48 phospholipase A2 group IB Homo sapiens 94-110 2429529-0 1986 Effects of mepacrine and p-bromophenacyl bromide on anti-IgE and phospholipase A2-induced histamine release from human basophils. Quinacrine 11-20 phospholipase A2 group IB Homo sapiens 65-81 2429529-2 1986 Low concentrations of mepacrine and p-bromophenacyl bromide (BPB) inhibited both phospholipase A2- and anti-IgE-induced histamine release. Quinacrine 22-31 phospholipase A2 group IB Homo sapiens 81-97 3709328-7 1986 In contrast, indomethacin (5 mg/kg) and aspirin (200 mg/kg) as cyclooxygenase inhibitors or quinacrine (100 mg/kg) as a phospholipase A2 inhibitor significantly decreased both the pH and acid neutralizing capacity. Quinacrine 92-102 phospholipase A2 group IB Rattus norvegicus 120-136 16664845-2 1986 The H(+)-PPase catalyzed the electrogenic transport of H(+) into the vesicles, generating a pH gradient, inside acid (quinacrine fluorescence quenching), and a membrane potential, inside positive (Oxonol V fluorescence quenching). Quinacrine 118-128 inorganic pyrophosphatase 1 Homo sapiens 9-14 2867452-4 1986 Quinacrine, a phospholipase A2 inhibitor, reduced both basal and GRF-stimulated free arachidonate levels as well as GH release. Quinacrine 0-10 phospholipase A2 group IB Homo sapiens 14-30 2867452-4 1986 Quinacrine, a phospholipase A2 inhibitor, reduced both basal and GRF-stimulated free arachidonate levels as well as GH release. Quinacrine 0-10 growth hormone releasing hormone Homo sapiens 65-68 3779108-8 1986 Quinacrine, an inhibitor of phospholipase A2, attenuated the dilation response in a dose-dependent manner. Quinacrine 0-10 phospholipase A2 group IB Canis lupus familiaris 28-44 3879308-4 1985 Quinacrine, a phospholipase A2 inhibitor, methylene blue, a guanylate cyclase inhibitor and tetraethylammonium, a potassium permeability inhibitor, inhibited carbachol-induced relaxation and augmented the magnitude of norepinephrine-induced contraction only when endothelium was present. Quinacrine 0-10 phospholipase A2 group IB Rattus norvegicus 14-30 3832018-1 1985 Four compounds: amodiaquine, quinacrine, 1,4-(tele)-methylhistamine and metoprine, which in vitro effectively inhibit histamine N-methyltransferase (HMT) activity, were tested for their effects on histamine (HI) levels in the rat brain and ex vivo HMT activity. Quinacrine 29-39 histamine N-methyltransferase Rattus norvegicus 149-152 3832018-3 1985 Amodiaquine, quinacrine and 1,4-(tele)-methyl-HI weakly inhibited HMT activity ex vivo and they failed to alter HI levels in the rat brain. Quinacrine 13-23 histamine N-methyltransferase Rattus norvegicus 66-69 3931692-0 1985 Mepacrine (quinacrine) inhibition of thrombin-induced platelet responses can be overcome by lysophosphatidic acid. Quinacrine 0-9 coagulation factor II, thrombin Homo sapiens 37-45 3931692-0 1985 Mepacrine (quinacrine) inhibition of thrombin-induced platelet responses can be overcome by lysophosphatidic acid. Quinacrine 11-21 coagulation factor II, thrombin Homo sapiens 37-45 3931692-2 1985 Such synthesis of lysophosphatidic acid can be inhibited by mepacrine, an inhibitor of the phospholipase A2 which attacks phosphatidic acid to give lysophosphatidic acid. Quinacrine 60-69 phospholipase A2 group IB Homo sapiens 91-107 3931692-3 1985 In the present study, mepacrine was used at a concentration of 2.5-20 microM, sufficient to block aggregation and lysophosphatidic acid formation induced by 0.1 U/ml thrombin. Quinacrine 22-31 coagulation factor II, thrombin Homo sapiens 166-174 3931692-4 1985 Mepacrine, at this concentration, also blocked thrombin-induced phosphorylation of platelet myosin light chain and a 47 kDa protein, thrombin-induced secretion and thrombin-induced release of arachidonic acid from platelet phospholipids. Quinacrine 0-9 coagulation factor II, thrombin Homo sapiens 47-55 3931692-4 1985 Mepacrine, at this concentration, also blocked thrombin-induced phosphorylation of platelet myosin light chain and a 47 kDa protein, thrombin-induced secretion and thrombin-induced release of arachidonic acid from platelet phospholipids. Quinacrine 0-9 coagulation factor II, thrombin Homo sapiens 133-141 3931692-4 1985 Mepacrine, at this concentration, also blocked thrombin-induced phosphorylation of platelet myosin light chain and a 47 kDa protein, thrombin-induced secretion and thrombin-induced release of arachidonic acid from platelet phospholipids. Quinacrine 0-9 coagulation factor II, thrombin Homo sapiens 133-141 3931692-5 1985 However, mepacrine also partly inhibited the formation of phosphatidic acid in response to thrombin, consistent with some simultaneous inhibition of phospholipase C. Lysophosphatidic acid (2.5-22 microM) overcame the mepacrine block in thrombin-stimulated aggregation, protein phosphorylation and secretion without stimulating the release of arachidonic acid from platelet phospholipids or the formation of lysophosphatidic acid, and only slightly increasing phosphatidic acid formation. Quinacrine 9-18 coagulation factor II, thrombin Homo sapiens 91-99 3931692-5 1985 However, mepacrine also partly inhibited the formation of phosphatidic acid in response to thrombin, consistent with some simultaneous inhibition of phospholipase C. Lysophosphatidic acid (2.5-22 microM) overcame the mepacrine block in thrombin-stimulated aggregation, protein phosphorylation and secretion without stimulating the release of arachidonic acid from platelet phospholipids or the formation of lysophosphatidic acid, and only slightly increasing phosphatidic acid formation. Quinacrine 9-18 coagulation factor II, thrombin Homo sapiens 236-244 3931692-6 1985 The results suggest that lysophosphatidic acid primarily acts distal to mepacrine inhibition of phospholipase A2 and phospholipase C and are consistent with the possibility that lysophosphatidic acid might be a mediator of part of the effects of low-dose thrombin on human platelets. Quinacrine 72-81 phospholipase A2 group IB Homo sapiens 96-112 2995124-2 1985 NADH-dependent activation of 5"-nucleotidase was significantly suppressed by atebrine, an inhibitor of NADH dehydrogenase of plasma membranes, and completely abolished by 2,4-dinitrophenol (2 X 10(-4)M) and Triton X-100 (2%). Quinacrine 77-85 5' nucleotidase, ecto Rattus norvegicus 29-44 4016141-3 1985 Each of these lipolytic enzymes could be inhibited by antimalarial drugs (chloroquine, mepacrine, primaquine) at concentrations above 1 x 10(-4) M. Inhibition of the alkaline cytosolic lysophospholipase by these drugs was noncompetitive with respect to the substrate, and the inhibitory potency increased, when the pH was raised. Quinacrine 87-96 asparaginase Rattus norvegicus 185-202 3017321-4 1986 Similar inhibitory effects are observed with mepacrine, a PLA2-inhibitor, suggesting that PLA2-activation could be related to these secretory process. Quinacrine 45-54 phospholipase A2 group IB Homo sapiens 58-62 3017321-4 1986 Similar inhibitory effects are observed with mepacrine, a PLA2-inhibitor, suggesting that PLA2-activation could be related to these secretory process.

Quinacrine 59-69 phospholipase A2, group IB, pancreas Mus musculus 87-103 2425595-8 1986 There was apparently an increase in the cytoplasmic calcium concentration, which acted through calmodulin, since the histamine release induced by calcium from the permeabilized mast cells could be inhibited by a calmodulin-antagonist, mepacrine (10-30 microM). Quinacrine 235-244 calmodulin 1 Rattus norvegicus 95-105 2425595-8 1986 There was apparently an increase in the cytoplasmic calcium concentration, which acted through calmodulin, since the histamine release induced by calcium from the permeabilized mast cells could be inhibited by a calmodulin-antagonist, mepacrine (10-30 microM). Quinacrine 235-244 calmodulin 1 Rattus norvegicus 212-222 3455595-11 1986 was inhibitory at 10(-5) M and showed no effects at 10(-6) M. However, after washing quinacrine, normal elongation rate was recovered by those previously treated with 10(-5) M and axon growth was enhanced in those treated with 10(-6) M. Since three different phospholipase A2 inhibitors, tested in different situations, produce a similar biphasic effect on axon elongation rate, we postulate that this enzymatic activity is involved in the motility of axon growth cones.

Quinacrine 60-69 phospholipase A2 group IB Rattus norvegicus 73-89 7126467-5 1982 The pellet of isolated mepacrine-fluorescent granules consisted almost entirely of granules with the typical appearance of dense bodies, as shown by electron microscopy, and was relatively free from membranes and other granule populations as evaluated by the presence of the different markers (tritiated lectin, beta-glucuronidase, monoamine oxidase, platelet factor 4). Quinacrine 23-32 platelet factor 4 Homo sapiens 312-368 6752047-8 1982 Nonetheless, arachidonate metabolites were critical for the LAI phenomenon since BPB and mepacrine, inhibitors of phospholipase A2, negated the LAI response. Quinacrine 89-98 phospholipase A2 group IB Homo sapiens 114-130 6807980-10 1982 Indomethacin and aspirin, which inhibit the cyclooxygenase, and mepacrine, which inhibits the Ca2+-activated phospholipase A2, markedly reduced the increase in prostaglandin production. Quinacrine 64-73 phospholipase A2 group IB Rattus norvegicus 109-125 6810948-6 1982 Both bradykinin and ionophore A23187 stimulated [3H]arachidonate release from endothelial cell phospholipids, an effect which was abolished in a dose-dependent manner by mepacrine. Quinacrine 170-179 kininogen 1 Homo sapiens 5-15 6805948-5 1982 More specific phospholipase A2 inhibitors, mepacrine (20 mumol/mouse) and p-bromophenacyl bromide (10 mumol/mouse), also inhibited the ODC induction.

Quinacrine 43-52 ornithine decarboxylase, structural 1 Mus musculus 135-138 6805948-6 1982 The TPA-induced ODC inhibited by mepacrine was not restored by the treatment of mice with PGE2. Quinacrine 33-42 ornithine decarboxylase, structural 1 Mus musculus 16-19 6805948-7 1982 TPA-induced ODC inhibited by either mepacrine or p-bromophenacyl bromide was partially but significantly restored by treatment with arachidonic acid (1 to 40 mumol/mouse). Quinacrine 36-45 ornithine decarboxylase, structural 1 Mus musculus 12-15 6895907-4 1982 In addition, 3-deaza-SIBA, an inhibitor of transmethylation reactions and quinacrine, an inhibitor of phospholipase A2, appear to act before the Ca2+-dependent programming for lysis. Quinacrine 74-84 phospholipase A2, group IB, pancreas Mus musculus 102-118 6286943-2 1982 Active Cl, but not Na, transport across the toad cornea was inhibited by mepacrine, which is a phospholipase A2 inhibitor; trifluoperazine, which blocks the action of calmodulin; and meclofenamic acid, which inhibits synthesis of prostaglandins. Quinacrine 73-82 phospholipase A2 group IB Homo sapiens 95-111 7037068-5 1982 Aggregation and release of 14C-serotonin and PF4 were inhibited by the metabolic inhibitors 2-deoxyglucose (16.7 mM) and antimycin-A (8.3 micrograms/ml), by the membrane-active drugs mepacrine (10 microM) and chlorpromazine (0.025 mM), by PGI2 (5.34 nM), which elevates intracellular c-AMP, by indomethacin (10 microM) or aspirin (100 microM). Quinacrine 183-192 platelet factor 4 Homo sapiens 45-48 6701402-1 1984 Human platelets appear to accumulate quinacrine both in a thrombin-releasable compartment (dense bodies or amine storage vesicles) and in another compartment from which it is released by agents known to collapse pH gradients (possibly lysosomes with an acidic interior). Quinacrine 37-47 coagulation factor II, thrombin Homo sapiens 58-66 6803530-2 1981 The initial thrombin-activated phospholipase C-mediated reaction is quinacrine insensitive and is followed by quinacrine-sensitive phospholipase A2 activities. Quinacrine 68-78 coagulation factor II, thrombin Homo sapiens 12-20 6284950-4 1982 In the present study the effects of reported inhibitors of phospholipase A2 (quinacrine, chlorpromazine, dexamethasone, and dibutyryl cyclic AMP) on diethyl maleate (DEM)-induced lipid peroxidation, reduced glutathione (GSH) depletion, and cellular injury were examined in isolated hepatocyte suspensions. Quinacrine 77-87 phospholipase A2 group IB Rattus norvegicus 59-75 6281811-2 1982 Mepacrine (20 microgram/ml), an inhibitor of phospholipase A2, abolished the action of LTB4 on parenchymal strips. Quinacrine 0-9 prostaglandin reductase 1 Cavia porcellus 87-91 6803530-2 1981 The initial thrombin-activated phospholipase C-mediated reaction is quinacrine insensitive and is followed by quinacrine-sensitive phospholipase A2 activities. Quinacrine 68-78 phospholipase A2 group IB Homo sapiens 131-147 6803530-2 1981 The initial thrombin-activated phospholipase C-mediated reaction is quinacrine insensitive and is followed by quinacrine-sensitive phospholipase A2 activities. Quinacrine 110-120 coagulation factor II, thrombin Homo sapiens 12-20 6803530-2 1981 The initial thrombin-activated phospholipase C-mediated reaction is quinacrine insensitive and is followed by quinacrine-sensitive phospholipase A2 activities. Quinacrine 110-120 phospholipase A2 group IB Homo sapiens 131-147 7053072-3 1981 Indeed, the PLA2 inhibitors, bromophenacyl bromide (BPB), mepacrine, 874CB (100 microM), and EDTA (5 mM), blocked the zymosan-induced release of PAF-acether from PC. Quinacrine 58-67 phospholipase A2, group IB, pancreas Mus musculus 12-16 6117560-4 1981 The combination of 3-deazaadenosine and homocysteine thiolactone, which inhibits phospholipid methylation, and quinacrine, an inhibitor of phospholipase A2, also abolishes the response to the peptide. Quinacrine 111-121 phospholipase A2 Oryctolagus cuniculus 139-155 6798947-6 1981 Inhibitors of phospholipase A2 (mepacrine, p-bromophenacyl bromide) abolished the noradrenaline-induced PGE2-release and reduced the effect of A 23187; the stimulation of PGE2-release by arachidonic acid was not affected. Quinacrine 32-41 phospholipase A2 Oryctolagus cuniculus 14-30 6271829-3 1981 The release reaction could be antagonized by phospholipase A2 inhibitors such as quinacrine and quinine, suggesting that THC can stimulate the activity of this enzyme. Quinacrine 81-91 phospholipase A2 group IB Homo sapiens 45-61 6112882-8 1981 Daily injection of quinacrine (16 mg/kg), an antimalarial agent that inhibits phospholipase A2, blocked the subsensitivity to the chronotropic effect of epinephrine, but not that to the pressor effect of epinephrine. Quinacrine 19-29 phospholipase A2 group IB Rattus norvegicus 78-94 7281105-1 1981 We have examined whether inhibition by mepacrine or freeing of arachidonic acid from platelet phospholipids inhibits platelet aggregation to collagen, thrombin or ADP, and the release reaction induced by thrombin or collagen. Quinacrine 39-48 coagulation factor II, thrombin Homo sapiens 151-159 7281105-5 1981 Mepacrine inhibited ADP-induced platelet aggregation by inhibiting the association of fibrinogen with platelets during aggregation. Quinacrine 0-9 fibrinogen beta chain Homo sapiens 86-96 7281105-6 1981 The effect of mepacrine on fibrinogen binding could be considerably decreased by washing the platelets but the inhibition of 14C loss persisted. Quinacrine 14-23 fibrinogen beta chain Homo sapiens 27-37 7281105-8 1981 Thus, mepacrine has two effects; 1. it inhibits phospholipases, 2. it inhibits fibrinogen binding. Quinacrine 6-15 fibrinogen beta chain Homo sapiens 79-89 6785276-8 1981 The data thus indicate the existence of a quinacrine-insensitive phospholipase C which can initially convert a given amount of PI to PA and which is closely associated to the thrombin receptor. Quinacrine 42-52 coagulation factor II, thrombin Homo sapiens 175-183 6785276-9 1981 The further breakdown of PI and production of arachidonic acid might result from the action of quinacrine-sensitive activities (i.e. phospholipase A2). Quinacrine 95-105 phospholipase A2 group IB Homo sapiens 133-149 6785276-10 1981 The simplest scheme is one in which thrombin specifically produces an active fraction of PA which in some way results in the subsequent production of arachidonic acid from various phospholipids (including PI), perhaps by activation of quinacrine-sensitive phospholipase A2. Quinacrine 235-245 coagulation factor II, thrombin Homo sapiens 36-44 6785276-10 1981 The simplest scheme is one in which thrombin specifically produces an active fraction of PA which in some way results in the subsequent production of arachidonic acid from various phospholipids (including PI), perhaps by activation of quinacrine-sensitive phospholipase A2. Quinacrine 235-245 phospholipase A2 group IB Homo sapiens 256-272 7007379-6 1981 The phospholipase A2 inhibitors, chloroquine and quinacrine, prevented the effect of GnRH on arachidonic acid formation and LH release. Quinacrine 49-59 phospholipase A2 group IB Homo sapiens 4-20 7007379-6 1981 The phospholipase A2 inhibitors, chloroquine and quinacrine, prevented the effect of GnRH on arachidonic acid formation and LH release. Quinacrine 49-59 gonadotropin releasing hormone 1 Homo sapiens 85-89 6257888-3 1981 These changes in beta adrenoceptors were prevented by administration of quinacrine, a phospholipase A2 inhibitor, although the drug had no effect on beta adrenoceptors when given alone. Quinacrine 72-82 phospholipase A2 group IB Rattus norvegicus 86-102 6258719-6 1981 Interference with the metabolism of phospholipids by exposure to phospholipase A2 inhibitor, mepacrine (quinacrine), prevents agonist-induced desensitization of beta-adrenoceptors in astrocytoma cells.

Quinacrine 104-114 phospholipase A2 group IB Rattus norvegicus 65-81 922007-1 1977 The interactions of a quinacrine derivative, methylated at both the aromatic and aliphatic nitrogens, and propidium diiodide with the dinucleoside monophosphates CpG, GpC, UpA and ApU have been investigated using 13C-NMR (for the quinacrine derivative prepared with [13C]methyl substituents and 1H-NMR and ultraviolet-visible spectroscopy. Quinacrine 22-32 glycophorin C (Gerbich blood group) Homo sapiens 167-170 6262771-0 1981 Local anesthetics, mepacrine, and propranolol are antagonists of calmodulin. Quinacrine 19-28 calmodulin 1 Homo sapiens 65-75 7313587-5 1981 A 1-week course of metronidazole (200 mg 3 times daily) was successful in 8/9 failures; 1 patient was finally cured with mepacrine. Quinacrine 121-130 BCL2 related protein A1 Homo sapiens 0-3 6109256-4 1980 PG release was abolished by indometacin (1-3 microgram/ml) and reduced by the phospholipase A2 inhibitor quinacrine (10 microgram/ml) as well as by perfusing with calcium-free, 1 mM EGTA containing solution.

Quinacrine 47-56 calmodulin 1 Homo sapiens 14-24 533666-3 1979 Studies done with quinacrine staining of seven day old pupal foot-pad polytene nuclei showed that the granules fluoresced very brightly while the chromosomal bands to which the granules were attached did not. Quinacrine 18-28 Partner of Bursicon Drosophila melanogaster 55-60 533666-6 1979 Most of the label on these slides was concentrated on the centromeric heterochromatin of chromosomes C and E. Quinacrine staining of the foot-pad cells at very early stages of pupal development showed that when granules were present, they were always closely associated with the same two centromeric regions, those of chromosomes C and E. Since the highly repetitive DNA located in these centromeric regions is underreplicated, we conclude that the granules result from an extrusion process which takes place early during the polytenization of these cells. Quinacrine 110-120 Partner of Bursicon Drosophila melanogaster 176-181 225265-2 1979 Both these bradykinin-induced reactions are inhibited by quinacrine, an inhibitor of phospholipase A activity. Quinacrine 57-67 kininogen 1 Homo sapiens 11-21 95126-1 1979 Quinacrine at concentrations of 0.025 mM and greater significantly reduced or abolished the prolactin stimulation of RNA synthesis in mouse mammary gland explants.

Quinacrine 130-139 phospholipase A2 group IB Homo sapiens 92-108 6818615-5 1982 Mepacrine (phospholipase A2 inhibitor) also suppressed collagen dissolution. Quinacrine 0-9 phospholipase A2 group IB Homo sapiens 11-27 6257896-24 1980 These data suggest that quinacrine"s main action is a slow, voltage dependent blockade of open end-plate channels, though there are probably additional effects on acetylcholinesterase and channel opening. Quinacrine 24-34 acetylcholinesterase (Cartwright blood group) Homo sapiens 163-183 6246490-5 1980 Mepacrine and tetracaine, both inhibitors of this phospholipase A2, are able to block l-isoproterenol-induced desensitization of cyclic AMP production and the decrease in beta-adrenergic receptors.

Quinacrine 56-66 kininogen 1 Homo sapiens 14-24 922007-1 1977 The interactions of a quinacrine derivative, methylated at both the aromatic and aliphatic nitrogens, and propidium diiodide with the dinucleoside monophosphates CpG, GpC, UpA and ApU have been investigated using 13C-NMR (for the quinacrine derivative prepared with [13C]methyl substituents and 1H-NMR and ultraviolet-visible spectroscopy. Quinacrine 22-32 proline rich acidic protein 1 Homo sapiens 172-175 17672-5 1977 Such aggregation was inhibited by two phospholipase A2 inhibitors, bromophenacyl bromide and mepacrine. Quinacrine 93-102 phospholipase A2 Oryctolagus cuniculus 38-54 13413145-9 1957 The action of mepacrine on plasmodial hexokinase was reduced by raising the concentration of ATP, but, as with yeast hexokinase, the inhibition by 10,732 was independent of the ATP concentration.From a consideration of the results, it seems doubtful whether this type of inhibitory effect plays more than a minor part in the mechanism of antimalarial action in vivo. Quinacrine 14-23 hexokinase Saccharomyces cerevisiae S288C 38-48 837023-6 1977 6 Mepacrine, a drug which possesses weak anti-phospholipase activity in platelets, also prevents aggregation by collagen or thrombin, but seems to do so by preventing substrate release from the phosphatide fraction. Quinacrine 2-11 prothrombin Oryctolagus cuniculus 124-132 415534-4 1977 The phospholipase A2 inhibitors bromophenacyl bromide and mepacrine, the chymotrypsin inhibitor tosylphenylalaninechloromethylketone, catalase and dithiothreitol also inhibited aggregation, whereas inhibitors of trypsin failed to do so.
