Isolated strips of sheep umbilical arteries contracted in the presence of R-(-)-2-amino-1-(2,5-dimethoxy-4-methylphenyl) butane (BL3912A). These contractions faded over an hour period and at this time BL3912A antagonized contractions to R-(-)-DOM, 5-hydroxytryptamine (5-HT) but not to angiotensin. The initial contraction produced by BL3912A was antagonized by cinanserin, a 5-HT antagonist. These experiments indicate that BL3912A can be classified as a partial agonist of 5-HT receptors in sheep umbilical arteries.
在R-(-)-2-氨基-1-(2,5-二甲氧基-4-甲基苯基)丁烷(BL3912A)存在的情况下,分离出的羊脐动脉条会收缩。这些收缩在一小时内逐渐消退,此时BL3912A可拮抗对R-(-)-DOM、5-羟色胺(5-HT)的收缩反应,但对血管紧张素的收缩反应无拮抗作用。由BL3912A产生的初始收缩可被5-HT拮抗剂辛那色林所拮抗。这些实验表明,BL3912A可被归类为羊脐动脉中5-HT受体的部分激动剂。
