Abstract

- The study was performed to characterize pharmacologically the contractile 5-hydroxytryptamine (5-HT) receptors in the circular smooth muscle of the isolated human umbilical artery. Effects of agonists and antagonists for different 5-HT receptor subtypes were studied in intact endothelium vessel segments. All agonists induced concentration-dependent circular smooth muscle contractions. The potency was in declining order 5-HT > alpha-methyl-5-HT > sumatriptan >/= 2-methyl-5-HT. The effects of 5-HT and alpha-methyl-5-HT were antagonized by ketanserin, as well as methiothepin. The contractile effect of sumatriptan was antagonized by methiothepin but not by ketanserin. The 5-HT3 receptor antagonist, MDL 72222, did not affect the contraction by any of the agonists, including 2-methyl-5-HT. It is concluded that the 5-HT-induced contraction in the circular smooth muscle of the human umbilical artery seems to be mediated by a mixed population of 5-HT1-like receptors and 5-HT2 receptors.
