Evidence for 5-HT1-like receptor-mediated vasoconstriction in human pulmonary artery.[Pubmed:8886409]
Br J Pharmacol. 1996 Sep;119(2):277-82.
1. The 5-hydroxytryptamine (5-HT) receptors mediating contraction of human isolated pulmonary artery rings were investigated. Responses to the agonists 5-carboximidotryptamine (5-CT, non-selective 5-HT1 agonist), sumatriptan (5-HT1D-like receptor agonist), 5-HT and 8-hydroxy-2-(di-n-propylamino)-tetralin (8-OH-DPAT, 5-HT1A receptor agonist) were studied. Responses to 5-HT and sumatriptan in the presence of the antagonists, methiothepin (non-selective 5-HT1+2-receptor antagonist), ketanserin (5-HT2A receptor antagonist) and the novel antagonist, GR55562 (5-HT1D receptor antagonist) were also studied. 2. All agonists contracted human pulmonary artery ring preparations in the following order of potency 5-CT > 5-HT = sumatriptan > 8-OH-DPAT. Maximum responses to 5-HT, 5-CT and sumatriptan were not significantly different. 3. Methiothepin 1 nM and 10 nM, but not 0.1 nM reduced the maximum contractile responses to 5-HT but did not alter tissue sensitivity to 5-HT. Methiothepin 0.1 nM, 1 nM and 10 nM had a similar effect on responses to sumatriptan. 4. The 5-HT2A receptor antagonist ketanserin (10 nM, 100 nM and 1 microM) also reduced the maximum contractile response to both 5-HT and sumatriptan without affecting tissue sensitivity to these agonists. 5. The novel 5-HT1D receptor antagonist, GR55562, inhibited responses to 5-HT and sumatriptan in a true competitive fashion. 6. The results suggest that the human pulmonary artery has a functional population of 5-HT1D-like receptors which are involved in the contractile response to 5-HT.
The activity of 5-HT1D receptor ligands at cloned human 5-HT1D alpha and 5-HT1D beta receptors.[Pubmed:8666030]
Eur J Pharmacol. 1995 Dec 4;287(1):79-84.
The present study has examined the functional activity of the 5-HT1D receptor agonist, sumatriptan, and antagonists, GR127935 (2'-methyl-4'-(5-methyl-[1,2,4]oxadiazol-3-yl)-biphenyl-4-carboxyl ic acid [4-methoxy-3-(4-methyl-piperazin-1-yl)-phenyl]-amide), GR55562 (3-[3-(dimethylamino)propyl]-4-hydroxy-N-[4-(4-pyridinyl)phenyl] benzamide), metergoline and methiothepin in HeLa cells, stably transfected with either 5-HT1D alpha or 5-HT1D beta receptor subtypes. Sumatriptan, GR127935 and metergoline (each 0.01-1 microM) behaved as agonists, producing a concentration-dependent inhibition of forskolin-stimulated adenosine 3',5'-cyclic monophosphate (cAMP) production at both 5-HT1D alpha and 5-HT1D beta receptor subtypes (mean pIC50 values of 8.4 and 8.3 for sumatriptan, 7.9 and 8.0 for GR127935, and 7.9 and 8.3 for metergoline, respectively). In contrast, GR55562 and methiothepin behaved as competitive 5-HT1D receptor antagonists and were devoid of any agonist activity. GR55562 (10 microM) caused a rightward displacement of the GR127935 and metergoline concentration-response curves. The agonist activity of GR127935 and metergoline, observed in the present study, contrasts with their recognised 5-HT1D receptor antagonist profiles in animal isolated tissue and behavioural models. Unlike GR127935, GR55562 behaved as a silent antagonist at the cloned human 5-HT1D alpha and 5-HT1D beta receptors in the study.
