Ergotamine 95-105 5-hydroxytryptamine receptor 1A Rattus norvegicus 30-36 24975101-11 2014 The above results suggest that ergotamine induces inhibition of the vasopressor sympathetic outflow by activation of prejunctional 5-HT1A, 5-HT1B/1D, alpha2-adrenoceptors and D2-like receptors in pithed rats. Ergotamine 31-41 5-hydroxytryptamine receptor 1A Rattus norvegicus 131-137 24975101-11 2014 The above results suggest that ergotamine induces inhibition of the vasopressor sympathetic outflow by activation of prejunctional 5-HT1A, 5-HT1B/1D, alpha2-adrenoceptors and D2-like receptors in pithed rats.

Ergotamine 77-87 5-hydroxytryptamine receptor 1B Homo sapiens 175-182 15224175-1 2004 It has previously been suggested that ergotamine produces external carotid vasoconstriction in vagosympathectomised dogs via 5-HT1B/1D receptors and alpha2-adrenoceptors. Ergotamine 38-48 5-hydroxytryptamine receptor 1B Canis lupus familiaris 125-131 15224175-9 2004 Thus, the cranio-selective vasoconstriction elicited by ergotamine in dogs is predominantly mediated by 5-HT1B receptors as well as alpha2A/2C-adrenoceptor subtypes and, to a lesser extent, by alpha1-adrenoceptors.

Ergotamine 42-52 insulin like growth factor 1 Bos taurus 114-119 12781836-7 2003 Plasma IGF-1 decreased in response to ergotamine. Ergotamine 38-48 insulin like growth factor 1 Bos taurus 7-12 12781836-14 2003 Plasma IGF-1 decreased after ergotamine treatment. Ergotamine 29-39 insulin like growth factor 1 Bos taurus 7-12 12781836-16 2003 Results indicated ergotamine altered plasma metabolite and IGF-1 concentrations in cows.

Ergotamine 0-10 5-hydroxytryptamine receptor 1B Homo sapiens 58-64 12558771-3 2003 Ergotamine and dihydroergotamine are highly potent at the 5-HT1B and 5-HT1D antimigraine receptors and, as a consequence, the plasma concentrations that are necessary to produce the appropriate therapeutic and physiologic effects are very low. Ergotamine 0-10 5-hydroxytryptamine receptor 1D Homo sapiens 69-75 11518230-4 2001 Contractile responses to ergovaline and ergotamine were surmountably antagonized by the 5-HT2A receptor antagonist ketanserin (3 nM). Ergotamine 40-50 5-hydroxytryptamine receptor 2A Rattus norvegicus 88-94 12046966-11 2002 Both breeds responded to ergotamine with increased (p < 0.01) plasma cortisol, glucagon, and glucose and reduced (p < 0.01) insulin concentrations. Ergotamine 25-35 insulin Bos taurus 130-137 11044256-11 2000 The circulating Hp, TNF-alpha, and TXB(2) increases were blunted by pretreatment with ET compared with ET + LPS. Ergotamine 86-88 tumor necrosis factor Bos taurus 20-29 11104741-7 2000 (+/-)-, (+)-, and (-)-Norfenfluramine, ergotamine, and methylergonovine all had preferentially high affinities for the cloned human serotonin 5-HT(2B) receptor and were partial to full agonists at the 5-HT(2B) receptor. Ergotamine 39-49 5-hydroxytryptamine receptor 2B Homo sapiens 142-159 11104741-7 2000 (+/-)-, (+)-, and (-)-Norfenfluramine, ergotamine, and methylergonovine all had preferentially high affinities for the cloned human serotonin 5-HT(2B) receptor and were partial to full agonists at the 5-HT(2B) receptor. Ergotamine 39-49 5-hydroxytryptamine receptor 2B Homo sapiens 201-218 11044256-12 2000 Ergotamine by itself increased circulating cortisol and RT, whereas it decreased serum prolactin (PRL).

Ergotamine 0-10 insulin Bos taurus 53-60 10816333-6 2000 In the presence of ergotamine, the contractile response to noradrenaline was completely blocked not only in control animals, but also in animals treated with ANG II alone or in combination with minoxidil. Ergotamine 19-29 angiotensinogen Rattus norvegicus 158-164 10764077-1 2000 Bovine plasma was assayed to determine whether ergotamine, an ergopeptide isolated from endophytic tall fescue, affected cortisol, triiodothyronine, insulin, and glucagon concentrations. Ergotamine 47-57 insulin Bos taurus 149-156 10764077-22 2000 Insulin was decreased (P < .01) and glucagon increased (P < .01) within 1 h after ergotamine treatment, but they were not altered by saline. Ergotamine 88-98 insulin Bos taurus 0-7 10522646-9 1999 Ergotamine treatment significantly increased IL-6 levels at the 2.0 mg/kg dose and greater and TNF-alpha at the highest dose. Ergotamine 0-10 interleukin 6 Mus musculus 45-49 10682812-12 2000 Ergotamine decreased plasma (P < .01) prolactin and increased (P < .01) cortisol concentrations in both breeds, despite some breed variation. Ergotamine 0-10 prolactin Bos taurus 41-50 10522646-12 1999 Ergotamine affected the proinflammatory cytokine IL-6, and this increase may contribute to fescue tosicosis. Ergotamine 0-10 interleukin 6 Mus musculus 49-53 8397071-3 1993 This was carried out by assay of the thrombin-stimulated generation of inositol phosphates in platelets from 12 migraine patients with chronic daily headache and analgesic misuse, 7 migraine patients with chronic daily headache and ergotamine misuse and 7 control subjects. Ergotamine 232-242 coagulation factor II, thrombin Homo sapiens 37-45 10328360-4 1999 Ergovaline and ergotamine tartrate were equally effective in inhibiting vasoactive intestinal peptide (VIP)-stimulated cyclic AMP production, with consistent nanomolar effective concentration (EC50) values. Ergotamine 15-34 vasoactive intestinal peptide Rattus norvegicus 103-106 10328360-7 1999 Our results indicate that the commercially available ergot alkaloids ergotamine tartrate and ergonovine may be used interchangeably in the D2 dopamine receptor system to simulate the effects of extracted ergovaline and ergine and to examine responses in receptor binding and the inhibition of cyclic AMP. Ergotamine 69-88 dopamine receptor D2 Rattus norvegicus 139-159 9778659-1 1998 In the rat dorsal hippocampus and dorsal raphe nucleus, the microiontophoretic application of ergotamine and 5-HT suppressed the firing activity of CA3 pyramidal neurons and 5-HT neurons, an effect antagonized by selective 5-HT1A receptor antagonists. Ergotamine 94-104 carbonic anhydrase 3 Rattus norvegicus 148-151 9778659-1 1998 In the rat dorsal hippocampus and dorsal raphe nucleus, the microiontophoretic application of ergotamine and 5-HT suppressed the firing activity of CA3 pyramidal neurons and 5-HT neurons, an effect antagonized by selective 5-HT1A receptor antagonists. Ergotamine 94-104 5-hydroxytryptamine receptor 1A Homo sapiens 223-238 9778659-2 1998 Co-application of ergotamine prevented the inhibitory action of 5-HT on the firing activity of CA3 pyramidal neurons but not of 5-HT neurons, indicating that ergotamine acted as a partial 5-HT1A receptor agonist in the dorsal hippocampus and as a full agonist at 5-HT1A autoreceptors. Ergotamine 18-28 carbonic anhydrase 3 Homo sapiens 95-98 9778659-2 1998 Co-application of ergotamine prevented the inhibitory action of 5-HT on the firing activity of CA3 pyramidal neurons but not of 5-HT neurons, indicating that ergotamine acted as a partial 5-HT1A receptor agonist in the dorsal hippocampus and as a full agonist at 5-HT1A autoreceptors. Ergotamine 158-168 carbonic anhydrase 3 Homo sapiens 95-98 9778659-2 1998 Co-application of ergotamine prevented the inhibitory action of 5-HT on the firing activity of CA3 pyramidal neurons but not of 5-HT neurons, indicating that ergotamine acted as a partial 5-HT1A receptor agonist in the dorsal hippocampus and as a full agonist at 5-HT1A autoreceptors. Ergotamine 158-168 5-hydroxytryptamine receptor 1A Homo sapiens 188-203 9778659-2 1998 Co-application of ergotamine prevented the inhibitory action of 5-HT on the firing activity of CA3 pyramidal neurons but not of 5-HT neurons, indicating that ergotamine acted as a partial 5-HT1A receptor agonist in the dorsal hippocampus and as a full agonist at 5-HT1A autoreceptors. Ergotamine 158-168 5-hydroxytryptamine receptor 1A Homo sapiens 188-194 9778659-4 1998 Although body temperature in humans remained unchanged following inhaled ergotamine, in the rat, subcutaneously injected ergotamine produced a hypothermia that was prevented by a pretreatment with the 5-HT1A/1B receptor/beta-adrenoceptor antagonist pindolol. Ergotamine 121-131 5-hydroxytryptamine receptor 1A Homo sapiens 201-207 9778659-5 1998 Finally in humans, ergotamine did not alter prolactin or adrenocorticotropic hormone levels, but increased growth hormone level, which was prevented by pindolol. Ergotamine 19-29 growth hormone 1 Homo sapiens 107-121 9778659-7 1998 In conclusion, the present results suggest that ergotamine acted in the rat brain as a 5-HT1A receptor agonist and as an agonist of terminal 5-HT autoreceptor of a yet undefined subtype. Ergotamine 48-58 5-hydroxytryptamine receptor 1A Homo sapiens 87-102 9778659-8 1998 In humans, ergotamine also displayed some 5-HT1A receptor activity but, probably because of lack of receptor selectivity, it did not present the same profile as other 5-HT1A receptor agonists. Ergotamine 11-21 5-hydroxytryptamine receptor 1A Homo sapiens 42-57 9605061-2 1998 Ergotamine produced a 27% reduction in hyperemic MBF (2.62 +/- 0.11 vs 3.72 +/- 1.05 ml x min(-1) x g(-1); p <0.05), a 31% reduction in the coronary vasodilator reserve (1.81 +/- 0.50 vs 2.71 +/- 1.15; p <0.01), and a 55% increase in minimal coronary resistance (42.2 +/- 15 vs 26.7 +/- 8 mm Hg x min x ml(-1) x g(-1); p <0.001), suggesting vasoconstriction of the coronary microcirculation. Ergotamine 0-10 CD59 molecule (CD59 blood group) Homo sapiens 90-96 9605562-3 1998 The present study was devoted to establish the contribution of 5-HT1B/1D receptors in the constriction of AVAs elicited by 5-HT (in presence of 0.5 mg kg(-1) ketanserin), ergotamine and dihydroergotamine in anaesthetized pigs. Ergotamine 171-181 5-hydroxytryptamine receptor 1B Sus scrofa 63-69 9613443-4 1998 Ergotamine (EG) was conjugated to bovine serum albumin (BSA) and cholera toxin subunit B (CTB) by the Mannich reaction. Ergotamine 0-10 phosphate cytidylyltransferase 1, choline, beta isoform Mus musculus 90-93 9613443-4 1998 Ergotamine (EG) was conjugated to bovine serum albumin (BSA) and cholera toxin subunit B (CTB) by the Mannich reaction. Ergotamine 12-14 phosphate cytidylyltransferase 1, choline, beta isoform Mus musculus 90-93 9613443-11 1998 Weight gains were increased in the BSA-EG and CTB-EG groups and tended to be increased in the MoAB group vs. the unvaccinated EI group. Ergotamine 50-52 phosphate cytidylyltransferase 1, choline, beta isoform Mus musculus 46-49 7665369-3 1995 Ergot alkaloids were also effective in inhibiting VIP-stimulated cyclic AMP production, with EC50 values for ergovaline, ergonovine, alpha-ergocryptine, ergotamine, and dopamine of 8 +/- 2, 47 +/- 2, 28 +/- 2, 2 +/- 1, and 8 +/- 1 nM, respectively. Ergotamine 153-163 vasoactive intestinal peptide Rattus norvegicus 50-53 7928330-3 1994 The clinical effective dose of ergotamine, beginning from the minimal dose of 1 mg, correlates well with its affinity for 5-HT1B and 5-HT1D receptors, and the rank order of clinical potency of ergotamine is superior to sumatriptan. Ergotamine 31-41 5-hydroxytryptamine receptor 1B Homo sapiens 122-128 7672873-1 1994 The double-label flow cytometric analysis of peripheral serotonergic pathways of migraine and cluster headache on a monocyte model has been used to evaluate the activity of drugs with a selective activity on central vascular 5-HT1D receptors, such as sumatriptan, ergotamine and ondansetron. Ergotamine 264-274 5-hydroxytryptamine receptor 1D Homo sapiens 225-231 10463349-4 1999 Sumatriptan, a specific serotonin (5-HT)1B/D agonist is used when attacks do not respond to ergotamine, or when intolerable side effects occur. Ergotamine 92-102 5-hydroxytryptamine receptor 1B Homo sapiens 35-42 9078499-11 1997 Ergotamine reduced (P < .01) plasma concentrations of prolactin and LH throughout the 120-min period after treatment compared with concentrations before ergotamine treatment and after saline treatment. Ergotamine 0-10 prolactin Bos taurus 57-66 8886417-7 1996 The relaxation to both ergotamine and 5-HT was associated with an increase in cyclic GMP.

Ergotamine 88-98 dopamine receptor D2 Homo sapiens 0-20 1513320-7 1992 The rank order of potency of ligands to compete for the [3H]5-HT-labeled site best matched the binding profile of the pharmacologically defined 5-HT1E binding site, 5-HT greater than methysergide greater than ergotamine greater than 8-hydroxy-2-(di-n-propylamino)tetralin greater than 5-carboxyamidotryptamine greater than ketanserin. Ergotamine 209-219 5-hydroxytryptamine receptor 1E Homo sapiens 144-150 7682702-3 1993 Saturable binding of 125I-labeled (+)-lysergic acid diethylamide to transiently expressed MR22 in COS-M6 cells was inhibited by ergotamine > methiothepin > 5-carboxamidotryptamine > 5-HT. Ergotamine 128-138 5-hydroxytryptamine (serotonin) receptor 5B Rattus norvegicus 90-94 7682702-4 1993 For REC17, the rank of potency was ergotamine > 5-carboxamidotryptamine > methiothepin > methysergide > 5-HT. Ergotamine 35-45 5-hydroxytryptamine (serotonin) receptor 5B Rattus norvegicus 4-9 6735611-6 1984 A practically insuperable obstacle is rearrangement of ergotamine under the experimental conditions, forming a stereoisomer by inversion at the C-8 position. Ergotamine 55-65 homeobox C8 Homo sapiens 144-147 34803446-9 2021 MM/GBSA calculations from MD simulations showed that eltrombopag, glimepiride, sitagliptin, dutasteride, and ergotamine stably and strongly bind to NRP1. Ergotamine 109-119 neuropilin 1 Homo sapiens 148-152 3917386-3 1985 In contrast, ergotamine was quickly absorbed (t1/2 = 3 min) and plasma levels (measured by HPLC) declined, with a biologic t1/2 of 2.5 hr. Ergotamine 13-23 CD5 molecule Homo sapiens 123-134 2664084-3 1989 One of these sites demonstrated high affinity for 5-carboxyamidotryptamine (5-CT) and ergotamine, consistent with the known pharmacology of the 5-HT1D receptor; the second site demonstrated low affinity for 5-CT and ergotamine. Ergotamine 86-96 5-hydroxytryptamine receptor 1D Homo sapiens 144-150 2664084-3 1989 One of these sites demonstrated high affinity for 5-carboxyamidotryptamine (5-CT) and ergotamine, consistent with the known pharmacology of the 5-HT1D receptor; the second site demonstrated low affinity for 5-CT and ergotamine. Ergotamine 216-226 5-hydroxytryptamine receptor 1D Homo sapiens 144-150 2664084-7 1989 Competition studies with nonradioactive drugs indicated that, of the drugs tested, 5-CT and ergotamine displayed the highest selectivity for the 5-HT1D site versus the 5-HT1E site. Ergotamine 92-102 5-hydroxytryptamine receptor 1D Homo sapiens 145-151 2664084-7 1989 Competition studies with nonradioactive drugs indicated that, of the drugs tested, 5-CT and ergotamine displayed the highest selectivity for the 5-HT1D site versus the 5-HT1E site. Ergotamine 92-102 5-hydroxytryptamine receptor 1E Homo sapiens 168-174 20488103-2 1984 We report here that certain ergot derivatives of the ergopeptine class, such as bromocriptine, ergotamine and codergocrine known to interact with alpha-adrenergic receptors, will also potentiate the effects of VIP on cyclic-AMP levels, without increasing directly the levels of the cyclic nucleotide. Ergotamine 95-105 vasoactive intestinal polypeptide Mus musculus 210-213 7430884-4 1980 In contrast, ergotamine reduced secretion of both GH and prolactin and considerably inhibited the growth of the tumour. Ergotamine 13-23 gonadotropin releasing hormone receptor Rattus norvegicus 50-52 1126359-6 1975 The response to ACh was affected in accordance with the prediction of an action of ACh and ergotamine on different receptors. Ergotamine 91-101 acyl-CoA thioesterase 12 Rattus norvegicus 16-19 33419260-3 2020 We performed molecular dynamics simulations with known beta-arrestin-biased ligands like lysergic acid diethylamide and ergotamine in complex with the 5-HT2B receptor and discovered that the extent of ligand bias is directly connected with the degree of closure of the extracellular loop region. Ergotamine 120-130 5-hydroxytryptamine receptor 2B Homo sapiens 151-166
