The design, synthesis, and biological evaluation of a novel series of 3-[2-(pyrrolidin-1-yl)ethyl]indoles with excellent selectivity for h5-HT1D (formerly 5-HT1Dalpha) receptors over h5-HT1B (formerly 5-HT1Dbeta) receptors are described. Clinically effective antimigraine drugs such as Sumatriptan show little selectivity between h5-HT1D and h5-HT1B receptors. The differential expression of h5-HT1D and
设计,合成和生物学评估的新型3- [2-(吡咯烷-1-基)乙基]吲哚与h5-HT1B(以前为5-描述了HT1Dbeta)受体。临床上有效的抗偏头痛药物,例如舒马普坦,在h5-HT1D和h5-HT1B受体之间显示出很小的选择性。h5-HT1D和h5-HT1B受体在神经和血管组织中的差异表达促使人们开始研究选择性针对h5-HT1D亚型的化合物是否具有相同的临床疗效,但副作用减少。最初确定吡咯烷3b对h5-HT1D的选择性是h5-HT1B受体的9倍。用甲基苄胺基团取代3b的吡咯烷环,得到对h5-HT1D受体具有纳摩尔摩尔亲和力的化合物,相对于h5-HT1B受体具有100倍的选择性。吲哚5-取代基的修饰导致恶唑烷酮24a,b对h5-HT1D亚型具有高达163倍的选择性,并且与其他5-羟色胺受体相比具有更高的选择性。通过测量激动剂诱导的由h5-HT受体表达的CHO细胞中的[35S] GTPgamma
