5-Hydroxytryptamine (5-HT), 5-carboxamidotryptamine and 8-hydroxy-2-(di-n-propylamino)-tetralin inhibited rat ventromedial hypothalamic neurones in vitro in a concentration-dependent manner. The agonist-induced inhibition was reduced by spiperone (1 microM) and by pertussis toxin , but not by MDL 72222 (10 microM) or ketanserin (1 microM). The inhibition appeared to be mediated via 5-HT1A-receptors and a pertussis toxin-sensitive pathway.
5-羟色胺(5-HT)、5-羧酰胺色胺和8-羟基-2-(二正丙基氨基)-四氢萘在体外以浓度依赖性方式抑制大鼠腹内侧下丘脑神经元。激动剂诱导的抑制作用被舒必利(1微摩尔)和百日咳毒素降低,但未被MDL 72222(10微摩尔)或酮色林(1微摩尔)降低。这种抑制作用似乎是通过5-HT1A受体和一条对百日咳毒素敏感的途径介导的。
