A series of novel indazole derivatives were synthesized, and their structure-activity relationships examined in order to identify potent and selective 5-HT2C receptor agonists. Among these compounds, (S)-2-(7-ethyl-1H-furo[2,3-g]indazol-1-yl)-1-methylethylamine (YM348) had a good in vitro profile, that is, high agonistic activity to the human 5-HT2C receptor subtype (EC50 = 1.0 nM) and high selectivity
合成了一系列新颖的吲唑衍生物,并检查了它们的结构-活性关系,以鉴定有效的和选择性的5-HT 2C受体激动剂。在这些化合物中,(S)-2-(7-乙基-1H-呋喃[2,3-g]吲唑-1-基)-1-甲基乙胺(YM348)具有良好的体外特性,即高激动性对人5-HT2C受体亚型的活性(EC50 = 1.0 nM)和对5-HT2A受体的高选择性。口服给予该化合物在大鼠阴茎勃起模型中也有效
