Diltiazem 173-182 3-hydroxy-3-methylglutaryl-CoA reductase Rattus norvegicus 69-121 22358108-12 2011 The increase in diltiazem oral bioavailability might be attributable to enhanced absorption in the small intestine via the inhibition of P-gp and to reduced first-pass metabolism of diltiazem via the inhibition of the CYP3A subfamily in the small intestine and/or in the liver rather than renal elimination of diltiazem by simvastatin. Diltiazem 16-25 ATP-binding cassette, subfamily B (MDR/TAP), member 1B Rattus norvegicus 137-141 21084035-4 2010 The possible relative risk factors included advanced age, chronic and systemic diseases, and co-administration of cytochrome P450 3A (CYP3A) enzyme-dependent metabolic drugs or its inhibitors such as clopidogrel and diltiazem. Diltiazem 216-225 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 114-132 21084035-4 2010 The possible relative risk factors included advanced age, chronic and systemic diseases, and co-administration of cytochrome P450 3A (CYP3A) enzyme-dependent metabolic drugs or its inhibitors such as clopidogrel and diltiazem. Diltiazem 216-225 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 134-139 21929464-5 2011 CONCLUSIONS: Although the differences were mainly quantitative and very small, the study has shown for the first time that the metabolism profiles of DTZ in SHR and WKY rats were closer to humans than SDR, and they may be more preferable rat models to study pharmacokinetic and metabolism studies of DTZ or similar agents.

Diltiazem 111-114 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 161-166 12951478-9 2003 These results indicated that the concomitant use of GBE in rats increased the bioavailability of DTZ by inhibiting both intestinal and hepatic metabolism, at least in part, via a mechanism-based inhibition for CYP3A. Diltiazem 97-100 cytochrome P450, family 3, subfamily a, polypeptide 62 Rattus norvegicus 210-215 14518598-0 2003 L-calcium channel blockade induced by diltiazem inhibits proliferation, migration and F-actin membrane rearrangements in human vascular smooth muscle cells stimulated with insulin and IGF-1.

Diltiazem 133-142 low density lipoprotein receptor Homo sapiens 104-108 10363626-12 1999 CONCLUSION: These studies show that diltiazem and verapamil increase LDLr gene transcription and expression which is independent of cell proliferation in HMCL. Diltiazem 36-45 low density lipoprotein receptor Homo sapiens 69-73 10217527-10 1999 Removal of Ca2+ by the addition of EGTA or application of Ca2+-channel blockers, verapamil, diltiazem, and Ni2+, inhibited the BK-induced IP accumulation and Ca2+ mobilization, indicating that Ca2+ influx was required for the BK-induced responses. Diltiazem 92-101 kininogen 1 Canis lupus familiaris 127-129 9865510-3 1998 In the presence of diltiazem (10 microM), maximal contraction to vasopressin was reduced to a greater extent in male (65+/-2%) than in female aortae (38+/-1%).

Diltiazem 92-101 insulin Homo sapiens 204-211 10396583-9 1999 We conclude that captopril and, to a lesser extent, diltiazem improve insulin sensitivity in patients with stable coronary artery disease. Diltiazem 52-61 insulin Homo sapiens 70-77 9753624-4 1998 The effect of UCN (10(-7)M) was not only blunted by cAMP-dependent protein kinase A (PKA) inhibitor, H-89 (10(-5)M), but also diltiazem (10(-7)M), a voltage-dependent Ca2+ channel blocker. Diltiazem 126-135 urocortin Rattus norvegicus 14-17 9877310-6 1998 Diltiazem and the metabolites reduced both SBP and DBP, the effects of diltiazem being most potent.

Diltiazem 0-9 vitamin D-binding protein Oryctolagus cuniculus 51-54 9777817-9 1998 RESULTS: Clonidine and diltiazem had consistent response rates regardless of renin profile (76%, 67%, and 80% for low, medium, and high renin, respectively, for clonidine and 83%, 82%, and 83%, respectively, for diltiazem for patients with baseline DBP of 95-99 mm Hg). Diltiazem 23-32 renin Homo sapiens 136-141 9787942-11 1998 These findings suggest that CsA induced acute vasoconstriction and renal hypoperfusion are mediated by ET-1 and that diltiazem treatment abolishes these pharmacodynamic effects of CsA despite persistent increase of plasma ET-1 levels. Diltiazem 117-126 endothelin 1 Homo sapiens 222-226 9765513-1 1998 We examined the effects of the calcium channel blockers nitrendipine, diltiazem, verapamil, bepridil, and mibefradil on the cloned HERG and KvLQT1/IsK K+ channels. Diltiazem 70-79 potassium voltage-gated channel subfamily H member 2 Homo sapiens 131-135 9765513-1 1998 We examined the effects of the calcium channel blockers nitrendipine, diltiazem, verapamil, bepridil, and mibefradil on the cloned HERG and KvLQT1/IsK K+ channels.

Diltiazem 221-230 potassium voltage-gated channel subfamily H member 2 Homo sapiens 41-45 9741502-4 1998 METHODS: In this pilot study, 59 patients with an AMI treated with tissue-type plasminogen activator (t-PA) were randomized, double blinded, to intravenous diltiazem or placebo for 48 h, followed by oral therapy for 4 weeks.

Diltiazem 14-23 endothelin 1 Homo sapiens 71-75 9782065-11 1998 Ability of Mg, diltiazem and leumedins to decrease the ET-1 plasma level may have direct clinical implications for the use of these agents in patients with coronary artery disease. Diltiazem 15-24 endothelin 1 Homo sapiens 55-59 9544975-7 1998 Mg or diltiazem similarly affects the plasma Fn, reducing its release during the entire reperfusion period, and did not influence the plasma Fn in the absence of myocardial injury. Diltiazem 6-15 fibronectin 1 Homo sapiens 45-47 9688645-10 1998 The L-type Ca2+ channel blocker diltiazem (10 microM) and the Ca2+ chelator EGTA (1 mM) significantly inhibited BB-stimulated secretin release by 64% and 59%, respectively, and inhibited PACAP-stimulated release by 75% and 55%, respectively. Diltiazem 32-41 adenylate cyclase activating polypeptide 1 Rattus norvegicus 187-192 9765513-5 1998 Similarly, KvLQT1/IsK is inhibited by bepridil (EC50 = 10.0 microM) and mibefradil (EC50 = 11.8 microM), while being insensitive to nitrendipine, diltiazem, or verapamil. Diltiazem 146-155 potassium voltage-gated channel subfamily Q member 1 Homo sapiens 11-17 9765513-5 1998 Similarly, KvLQT1/IsK is inhibited by bepridil (EC50 = 10.0 microM) and mibefradil (EC50 = 11.8 microM), while being insensitive to nitrendipine, diltiazem, or verapamil. Diltiazem 146-155 potassium voltage-gated channel subfamily E regulatory subunit 1 Homo sapiens 18-21 9667821-5 1998 Previously we have demonstrated that the calcium channel blockers verapamil and diltiazem, as well as dantrolene, an agent that blocks the release of calcium from its cytoplasmic stores, inhibits tumor necrosis factor-a (TNF-alpha) and augments interleukin-10 (IL-10) plasma levels in endotoxemic BALB/c mice. Diltiazem 80-89 tumor necrosis factor Mus musculus 221-230 9663178-12 1998 CONCLUSIONS: Both verapamil and diltiazem considerably increase plasma buspirone concentrations, probably by inhibiting its CYP3A4-mediated first-pass metabolism.

Diltiazem 15-24 fibronectin 1 Homo sapiens 59-61 9531253-8 1998 In addition, inhibition of protein kinase C by staurosporine (10 nmol/L) and blockade of L-type Ca2+ channels by diltiazem (1 micromol/L) significantly decreased the sustained phase of ADM-induced increase in developed tension. Diltiazem 113-122 adrenomedullin Rattus norvegicus 185-188 9514900-3 1998 In both cardiac SLM and SR, the felodipine fluorescence was sensitive to conformational changes of the DHPR, as diltiazem that binds to DHPR at a separate site altered the values of both the Kd and the Hill coefficient characteristic for felodipine binding. Diltiazem 112-121 calcium voltage-gated channel subunit alpha1 S Homo sapiens 103-107 9514900-3 1998 In both cardiac SLM and SR, the felodipine fluorescence was sensitive to conformational changes of the DHPR, as diltiazem that binds to DHPR at a separate site altered the values of both the Kd and the Hill coefficient characteristic for felodipine binding.

Diltiazem 75-84 phospholipase A2 group IB Homo sapiens 126-142 9405282-10 1998 Inhibition of Type-I and -IV Ca2+ influxes by their respective inhibitors, diltiazem and nifedipine, resulted in abolition of phospholipase A2 activation induced by the respective receptor agonists, in agreement with the notion that Ca2+ influx via these routes is responsible for receptor-mediated phospholipase A2 activation. Diltiazem 75-84 phospholipase A2 group IB Homo sapiens 299-315 10366993-10 1998 Both phenobarbital and DTZ decreased SBP and DBP significantly without affecting the HR.

Diltiazem 63-72 carbonic anhydrase 2 Rattus norvegicus 92-95 9437739-6 1998 Both nifedipine (1-50 microM) and diltiazem (1-50 microM) inhibited substance P-evoked Ca2+ responses in a dose-dependent manner. Diltiazem 34-43 tachykinin precursor 1 Homo sapiens 68-79 9370178-6 1997 Diltiazem reduced the dose of CsA required to maintain target blood levels (479 +/- 189 mg/d v 576 +/- 178 mg/d at 14 days; P = 0.015). Diltiazem 0-9 ERCC excision repair 8, CSA ubiquitin ligase complex subunit Homo sapiens 30-33 9481610-6 1997 L-CHANNEL CALCIUM ANTAGONISTS: Depending on their pharmacodynamic characteristics, L-channel calcium antagonists of the dihydropyridine, verapamil or diltiazem type reflexly activate the sympathetic nervous system and blunt beta-adrenoceptor-mediated calcium influx, thus eliciting negative inotropy and activation of the renin-angiotensin system. Diltiazem 150-159 renin Homo sapiens 322-327 9223567-7 1997 CYP3A4 in lymphoblastoid cell microsomes catalyzed DTZ N-demethylation but CYP2C8 and CYP2C9 were also active (approximately 20% and 10% of the activity supported by CYP3A4); seven other CYPs produced little or no N-desmethyl DTZ from DTZ. Diltiazem 51-54 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 0-6 9352390-16 1997 This model is additionally supported by the finding that the shape of the hysteresis is dependent on the absorption rate of diltiazem, calculated as mean input time according to MIT = MRT - 1/lambda z.

Diltiazem 36-39 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 0-6 9223567-16 1997 These findings suggest that N-demethylated metabolites of DTZ may contribute to CYP3A4 inhibition in vivo, especially under conditions in which N-desmethyl DTZ accumulates, such as during prolonged DTZ therapy. Diltiazem 58-61 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 80-86 9223567-16 1997 These findings suggest that N-demethylated metabolites of DTZ may contribute to CYP3A4 inhibition in vivo, especially under conditions in which N-desmethyl DTZ accumulates, such as during prolonged DTZ therapy.

Diltiazem 50-59 parathyroid hormone Homo sapiens 13-16 8473401-12 1993 These data demonstrate that diltiazem, but not felodipine, stimulates PTH secretion in vivo in man, with a maximal effect observed under hypocalcemic conditions.

Diltiazem 269-272 angiotensinogen Homo sapiens 34-39 1452374-7 1992 Diltiazem also tended to decrease plasma bradykinin, thromboxane B2, and 6-keto-prostaglandin F1 alpha levels. Diltiazem 0-9 kininogen 1 Homo sapiens 41-51 1452374-9 1992 Further, bradykinin was significantly decreased by diltiazem only in patients with exercise-induced silent ischemia or no exercise-induced ischemia, while the thromboxane B2/6-keto-prostaglandin F1 alpha ratio was unaffected by the administration of diltiazem.

Diltiazem 7-16 selenium binding protein 1 Homo sapiens 70-73 1884720-8 1991 In the diltiazem group, supine BP was reduced by 10 (11)/10 (6) mmHg (SBP/DBP) at the highest dose level, and the corresponding values for the metoprolol group were 7 (16)/8 (9) mmHg (SBP/DBP). Diltiazem 7-16 D-box binding PAR bZIP transcription factor Homo sapiens 74-77 1884720-8 1991 In the diltiazem group, supine BP was reduced by 10 (11)/10 (6) mmHg (SBP/DBP) at the highest dose level, and the corresponding values for the metoprolol group were 7 (16)/8 (9) mmHg (SBP/DBP). Diltiazem 7-16 selenium binding protein 1 Homo sapiens 184-187 1884720-8 1991 In the diltiazem group, supine BP was reduced by 10 (11)/10 (6) mmHg (SBP/DBP) at the highest dose level, and the corresponding values for the metoprolol group were 7 (16)/8 (9) mmHg (SBP/DBP). Diltiazem 7-16 D-box binding PAR bZIP transcription factor Homo sapiens 188-191 2148481-2 1990 Verapamil and diltiazem (0.01 to 5 mM) inhibited both (Ca2+ + Mg2+)-ATPase activity and initial rates of 45Ca2+ net uptake analogously. Diltiazem 14-23 carbonic anhydrase 2 Homo sapiens 55-58 2148481-2 1990 Verapamil and diltiazem (0.01 to 5 mM) inhibited both (Ca2+ + Mg2+)-ATPase activity and initial rates of 45Ca2+ net uptake analogously. Diltiazem 14-23 dynein axonemal heavy chain 8 Homo sapiens 68-74 2148481-5 1990 Verapamil and diltiazem inhibited the calmodulin-Ca2+ transport concentration-effect relationship by changing its apparent affinity as well as the maximal velocity of the process. Diltiazem 14-23 carbonic anhydrase 2 Homo sapiens 49-52 2148481-8 1990 Our results suggest that verapamil, diltiazem and bepridil (0.01 to 0.3 mM), but not nifedipine (1 nM to 0.01 mM), in relatively high concentrations can antagonize the calmodulin-stimulated Ca2(+)-pump, i.e. the ATPase as well as the transport process. Diltiazem 36-45 carbonic anhydrase 2 Homo sapiens 190-193 2148481-8 1990 Our results suggest that verapamil, diltiazem and bepridil (0.01 to 0.3 mM), but not nifedipine (1 nM to 0.01 mM), in relatively high concentrations can antagonize the calmodulin-stimulated Ca2(+)-pump, i.e. the ATPase as well as the transport process. Diltiazem 36-45 dynein axonemal heavy chain 8 Homo sapiens 212-218 2095401-9 1990 The results suggest that the dimethylaminoethyl group of diltiazem is oxidized to an aldehyde group by microsomal cytochrome P-450 in the liver. Diltiazem 57-66 cytochrome P450, family 2, subfamily g, polypeptide 1 Rattus norvegicus 114-130 2176795-0 1990 Effects of diltiazem on renin-aldosterone and ACTH-adrenocortical function during upper abdominal surgery. Diltiazem 11-20 proopiomelanocortin Homo sapiens 46-50 2176795-1 1990 STUDY OBJECTIVE: To observe the effects of continuous intravenous infusion of diltiazem on the renin-aldosterone system and ACTH-adrenocortical axis responses during surgical stimulation. Diltiazem 78-87 renin Homo sapiens 95-100 2176795-10 1990 Adrenocorticotropic hormone was significantly lower in the diltiazem group compared with that in the control group 60 minutes after the start of surgery (p less than 0.05). Diltiazem 59-68 proopiomelanocortin Homo sapiens 0-27 2145465-7 1990 It is concluded that 1,4-dihydropyridines and verapamil and diltiazem did differently influence Ca2(+)-mediated increase in force of contraction. Diltiazem 60-69 carbonic anhydrase 2 Homo sapiens 96-99 2077185-6 1990 Nifedipine, diltiazem and verapamil showed a slight preventive effect on the cholesterol accumulation and on the reduction of elastin content in the aorta without a cholesterol lowering effect in the serum. Diltiazem 12-21 elastin Mus musculus 126-133 2169937-7 1990 Nicergoline and other Ca2+ antagonists dose-dependently blocked the T-type Ca2+ channel with an order of potency nicardipine greater than nicergoline greater than diltiazem. Diltiazem 163-172 carbonic anhydrase 2 Rattus norvegicus 22-25 2169937-7 1990 Nicergoline and other Ca2+ antagonists dose-dependently blocked the T-type Ca2+ channel with an order of potency nicardipine greater than nicergoline greater than diltiazem. Diltiazem 163-172 carbonic anhydrase 2 Rattus norvegicus 75-78 2169937-9 1990 The L-type Ca2+ channel was also blocked in the order nicardipine greater than nicergoline greater than diltiazem, although the T-type Ca2+ channel was more sensitive to nicergoline. Diltiazem 104-113 carbonic anhydrase 2 Rattus norvegicus 11-14 2382217-10 1990 However, both doses of diltiazem significantly improved peritoneal macrophage antigen presentation, Ia expression, and IL-1 synthesis. Diltiazem 23-32 interleukin 1 complex Mus musculus 119-123 2382217-11 1990 IL-6 synthesis was only increased with high doses of diltiazem, whereas both diltiazem doses decreased TNF production. Diltiazem 53-62 interleukin 6 Mus musculus 0-4 2382217-11 1990 IL-6 synthesis was only increased with high doses of diltiazem, whereas both diltiazem doses decreased TNF production. Diltiazem 77-86 tumor necrosis factor Mus musculus 103-106 2232165-7 1990 The marked reduction of stimulation-evoked pressor responses and norepinephrine release by diltiazem suggests that enhanced Ca2(+)-dependent adrenergic transmission may contribute to the exaggerated vascular sympathetic tone in salt-dependent hypertension. Diltiazem 91-100 carbonic anhydrase 2 Rattus norvegicus 124-127 2159405-6 1990 Inhibition of voltage-dependent calcium influx by diltiazem also antagonized the effect of EGF. Diltiazem 50-59 epidermal growth factor Gallus gallus 91-94 2166422-1 1990 We previously showed that the calcium channel blocker diltiazem raises cytosolic Ca2+ and inhibits PTH release in bovine parathyroid cells. Diltiazem 54-63 parathyroid hormone Bos taurus 99-102 2166422-3 1990 Like diltiazem, TA-3090 (10(-6)-10(-4] produced a dose-dependent inhibition of immunoreactive PTH release at 0.5 mM Ca2+ and raised the cytosolic Ca2+ concentration by 25-50% in fura-2-loaded parathyroid cells in the presence but not in the absence of extracellular Ca2+, suggesting that it activated rather than inhibited Ca2+ channels. Diltiazem 5-14 parathyroid hormone Bos taurus 94-97 2140394-5 1990 IFN-gamma caused a rapid and concentration-dependent increase in [Ca2+]i, which was partly inhibited by calcium-free medium, diltiazem, and TMB-8. Diltiazem 125-134 interferon gamma Homo sapiens 0-9 2159347-6 1990 Other calcium antagonists such as diltiazem, nifedipine, nitrendipine or amphiphilic drugs such as phenothiazines and propranolol also enhanced HDL3 uptake by Hep G2 cells.

Diltiazem 27-36 selenium binding protein 1 Homo sapiens 405-408 1706014-4 1990 The reduction in DBP was significantly more pronounced in the group treated with sustained-release diltiazem 300 mg than in the group treated with enalapril 20 mg. Cardiac tolerance was good for patients treated with sustained-release diltiazem 300 mg alone or the combination therapy: no orthostatic hypotension or lengthening of the PR interval in the electrocardiogram was observed. Diltiazem 99-108 D-box binding PAR bZIP transcription factor Homo sapiens 17-20 1706014-4 1990 The reduction in DBP was significantly more pronounced in the group treated with sustained-release diltiazem 300 mg than in the group treated with enalapril 20 mg. Cardiac tolerance was good for patients treated with sustained-release diltiazem 300 mg alone or the combination therapy: no orthostatic hypotension or lengthening of the PR interval in the electrocardiogram was observed. Diltiazem 235-244 D-box binding PAR bZIP transcription factor Homo sapiens 17-20 1706015-9 1990 Moreover, on day 90, blood pressure values were maintained in the diuretic-treated group, whereas an additional significant reduction in supine DBP (p less than 0.002) was noted in the sustained-release diltiazem 300 mg-treated group (-4.8 mm Hg).

Diltiazem 27-36 colony stimulating factor 2 Homo sapiens 70-76 2553324-14 1989 Effects of low [Ca2+], diltiazem and TMB-8 on renin secretion were all shown to be reversible when superfusion with control buffer was resumed. Diltiazem 23-32 renin Rattus norvegicus 46-51 2553324-7 1989 The Ca2+ entry blocking drug diltiazem in a range of concentrations increased renin release and at 10(-5) mol/l diltiazem the mean stimulation was 35% (P less than 0.01). Diltiazem 29-38 renin Rattus norvegicus 78-83 2597113-10 1989 The rate of apo B secretion remained linear over 16 h even in the presence of 50 microM-diltiazem.

Diltiazem 3-12 apolipoprotein B Rattus norvegicus 68-73 2764137-6 1989 Only at high concentrations did verapamil (IC50 = 8.7 microM) and diltiazem (IC50 = 95.7 microM) inhibit the Ca2+ release from the cellular store sites, as induced by 10 microM histamine. Diltiazem 66-75 carbonic anhydrase 2 Rattus norvegicus 109-112 2764137-8 1989 From these results, we conclude that verapamil and diltiazem strongly inhibit the histamine-mediated, extracellular Ca2+-dependent intracellular [Ca2+] increase. Diltiazem 51-60 carbonic anhydrase 2 Rattus norvegicus 116-119 2764137-8 1989 From these results, we conclude that verapamil and diltiazem strongly inhibit the histamine-mediated, extracellular Ca2+-dependent intracellular [Ca2+] increase. Diltiazem 51-60 carbonic anhydrase 2 Rattus norvegicus 146-149 2764137-9 1989 In addition, verapamil and diltiazem seem to inhibit the release of Ca2+ from intracellular store sites, only at high concentrations, and probably by competing with histamine for binding to the H1-receptor. Diltiazem 27-36 carbonic anhydrase 2 Rattus norvegicus 68-71 2519888-6 1989 In decreasing order of potency, the following PAF-acether antagonists inhibited the change in platelet cytosolic free calcium elicited by 10 nM PAF-acether: L-652,731, kadsurenone, triazolam, diltiazem and alprazolam.

Diltiazem 186-195 apolipoprotein B Rattus norvegicus 41-46 2510664-10 1989 The decline in both SBP and DBP with diltiazem was significantly related to their control values (r = 0.31 and 0.28 respectively, p less than 0.0001 for both). Diltiazem 37-46 selenium binding protein 1 Homo sapiens 20-23 2510664-10 1989 The decline in both SBP and DBP with diltiazem was significantly related to their control values (r = 0.31 and 0.28 respectively, p less than 0.0001 for both).

Diltiazem 133-142 somatostatin Cavia porcellus 33-35 2635255-5 1989 Both diltiazem and atenolol significantly decreased heart rate at peak effort but the decrease was much more pronounced after atenolol (-52 b.min-1) than after diltiazem (-6 b.min-1). Diltiazem 5-14 CD59 molecule (CD59 blood group) Homo sapiens 142-147 2635255-5 1989 Both diltiazem and atenolol significantly decreased heart rate at peak effort but the decrease was much more pronounced after atenolol (-52 b.min-1) than after diltiazem (-6 b.min-1). Diltiazem 5-14 CD59 molecule (CD59 blood group) Homo sapiens 176-181 2668407-8 1989 The insulin peak was decreased by 13% during diltiazem treatment (P less than 0.05). Diltiazem 45-54 insulin Homo sapiens 4-11 2751676-4 1989 The extent of enhancement was different for the two drugs, and up to a 9- to 10-fold increase in harringtonine cytotoxicity occurred in P388/ADM cells, and 14- to 22-fold enhancement in K562/ADM cells with diltiazem or cepharanthine. Diltiazem 206-215 adrenomedullin Homo sapiens 186-194 2751676-5 1989 Harringtonine resistance of P388/ADM was circumvented completely, and the resistance of K562/ADM was circumvented partially, by diltiazem or cepharanthine. Diltiazem 128-137 adrenomedullin Homo sapiens 88-96 2751676-6 1989 The mechanism of enhanced cytotoxicity by diltiazem and cepharanthine is probably inhibition of active efflux of harringtonine in P388/ADM and K562/ADM cells. Diltiazem 42-51 adrenomedullin Homo sapiens 135-138 2751676-6 1989 The mechanism of enhanced cytotoxicity by diltiazem and cepharanthine is probably inhibition of active efflux of harringtonine in P388/ADM and K562/ADM cells. Diltiazem 42-51 adrenomedullin Homo sapiens 143-151 2723023-1 1989 PTH secretion is inversely related to the extracellular and cytosolic calcium (Ca2+) concentrations and, therefore, might be affected by calcium channel blockers such as diltiazem. Diltiazem 170-179 parathyroid hormone Bos taurus 0-3 2723023-3 1989 Diltiazem lowered serum PTH levels from 1.07 +/- 0.07 to 0.87 +/- 0.07 pg/L (P = 0.001), and increased urinary calcium and decreased urinary phosphate excretion (P less than 0.001 and P less than 0.01, respectively).

Diltiazem 61-70 parathyroid hormone Bos taurus 180-183 2723023-8 1989 In summary, diltiazem lowered PTH levels in vivo and in vitro, perhaps acting as a Ca2+ channel agonist in the parathyroid cell and inhibiting PTH release through a rise in the cytosolic Ca2+ concentration. Diltiazem 12-21 parathyroid hormone Bos taurus 30-33 2723023-8 1989 In summary, diltiazem lowered PTH levels in vivo and in vitro, perhaps acting as a Ca2+ channel agonist in the parathyroid cell and inhibiting PTH release through a rise in the cytosolic Ca2+ concentration. Diltiazem 12-21 parathyroid hormone Bos taurus 143-146 2723639-6 1989 On the other hand, diltiazem, which is a more potent blocker of the release of Ca2+ from the mitochondria, inhibited the increasing cytosolic free Ca2+ concentration at the third phase in a concentration-dependent manner.

Diltiazem 33-42 CD59 molecule (CD59 blood group) Homo sapiens 199-204 2657057-4 1989 Verapamil increased fasting serum immunoreactive insulin: diltiazem and propranolol tended to reduce it. Diltiazem 58-67 insulin Homo sapiens 49-56 2687079-6 1989 These effects of LH-RH were affected by phentolamine and diltiazem but not by propranolol and cold condition. Diltiazem 57-66 progonadoliberin-1 Cavia porcellus 17-22 2848686-3 1988 The positive inotropic effect of TRH was associated with an augmentation of slow action potentials in high K+ solution and was reduced in the presence of diltiazem, verapamil, and manganese. Diltiazem 154-163 thyrotropin releasing hormone Cavia porcellus 33-36 2473323-6 1989 Relaxation of ET-1-induced and NE-induced contractions by diltiazem was not complete (maximal at 58 +/- 6% with 10 microM diltiazem after 6 nM ET-1, and at 70 +/- 3% after 0.1 microM NE), in contrast to that of 80 mM K+-induced contractions, which were potently (IC50 = 0.2 microM) and completely reversed (100% relaxation at 10 microM diltiazem).

Diltiazem 97-106 growth hormone releasing hormone Homo sapiens 144-175 2853992-1 1988 We examined the effect of the voltage-sensitive Ca2+ channel antagonists, diltiazem and nifedipine, on basal and stimulated growth hormone (GH) release from purified somatotrophs. Diltiazem 74-83 growth hormone 1 Homo sapiens 124-138 2853992-4 1988 The release of GH induced by 29 mM K+ was blocked by diltiazem and nifedipine, at 10(-7) and 10(-8) M, respectively. Diltiazem 53-62 growth hormone 1 Homo sapiens 15-17 2853992-6 1988 The release of GH induced by growth hormone-releasing factor was significantly reduced by 10(-4) M diltiazem and completely blocked by nifedipine at a concentration of 10(-6) M or greater. Diltiazem 99-108 growth hormone 1 Homo sapiens 15-17 2853992-6 1988 The release of GH induced by growth hormone-releasing factor was significantly reduced by 10(-4) M diltiazem and completely blocked by nifedipine at a concentration of 10(-6) M or greater.

Diltiazem 64-73 neuropeptide Y Rattus norvegicus 162-165 3381103-3 1988 The increase was dependent on extracellular calcium and was inhibited by the antagonistic PAF analog CV-3988 and by the calcium-influx blockers prenylamine and diltiazem. Diltiazem 160-169 PCNA clamp associated factor Rattus norvegicus 90-93 3383374-1 1988 We investigated the effects of the Ca2+ antagonists diltiazem and verapamil on release of Ca2+ from intracellular store sites of rat aorta vascular smooth muscle cells in primary culture.

Diltiazem 30-39 C-C motif chemokine ligand 4 Rattus norvegicus 126-130 2451639-6 1988 In ganglion-blocked SHR, the smaller dose of diltiazem antagonized by 40 and 80% the pressor effects of norepinephrine and B-HT 920, respectively, but failed to change the vasoconstrictor responses of phenylephrine, epinephrine, or vasopressin, which were, however, reduced by the higher dose of diltiazem. Diltiazem 45-54 arginine vasopressin Rattus norvegicus 232-243 3395166-7 1988 In the canine femoral artery tensed up with high K+, all of these 3 CaM antagonists and 3 Ca++ channel blockers produced concentration-dependent vasorelaxation and relative potencies determined on the basis of concentrations producing IC30 were in the descending order: nicardipine greater than diltiazem greater than verapamil greater than calmidazolium greater than or equal to trifluoperazine greater than W-7. Diltiazem 295-304 calmodulin-3 Cavia porcellus 68-71 3277818-6 1988 Approximately 30 percent of our patients with PPH have been improved on diltiazem treatment.

Diltiazem 36-45 insulin Homo sapiens 86-93 2959345-10 1987 When added in Ca2+-containing solutions diltiazem and, to a lesser extent, nicardipine strongly reduced the contractions evoked in Ca2 -free solutions, suggesting that they inhibited the filling of the internal calcium store. Diltiazem 40-49 carbonic anhydrase 2 Rattus norvegicus 14-17 2891847-4 1988 Diltiazem also inhibited mesenteric vasoconstrictor responses to angiotensin II, vasopressin, prostaglandin F2 alpha and KCl. Diltiazem 0-9 angiotensinogen Homo sapiens 65-79 2891847-4 1988 Diltiazem also inhibited mesenteric vasoconstrictor responses to angiotensin II, vasopressin, prostaglandin F2 alpha and KCl. Diltiazem 0-9 arginine vasopressin Homo sapiens 81-92 2896538-7 1987 The calcium channel blockers nifedipine and diltiazem both partly inhibit GRF- and TPA-stimulated GH release, showing some component of the calcium necessary for GH release arises from influx across the cell membrane.

Diltiazem 44-53 renin Canis lupus familiaris 19-24 3623678-9 1987 The results suggest that in normal subjects increased DBP responses to ANG II, induced by an increase in sodium intake, are partially mediated by increased extracellular to intracellular calcium movements, since they are blocked by the structurally different calcium channel blocking drugs nifedipine and diltiazem. Diltiazem 305-314 angiotensinogen Homo sapiens 71-77 3604896-5 1987 In individuals with pretreatment glomerular filtration rates less than or equal to 80 ml/min/1.73m2, diltiazem monotherapy showed both short-term and long-term improvement in glomerular filtration rate (62%) and effective renal plasma flow (34%).
