5-HT(6) serotonin agonists. It was found that 5-HT(6) receptors accommodate small alkyl substituents at the indole 2-position and that the resulting compounds can bind with affinities comparable to that of serotonin. In particular, 2-ethyl-5-methoxy-N, N-dimethyltryptamine (8) binds with high affinity at human 5-HT(6) receptors (K(i) = 16 nM) relative to 5-HT (K(i) = 75 nM) and was a full agonist, at least
几种2-烷基-5-甲氧基色胺类似物被设计和制备为潜在的5-HT(6)5-羟色胺激动剂。发现5-HT(6)受体在吲哚2位上容纳小的烷基取代基,并且所产生的化合物可以结合具有与血清素相当的亲和力。特别是,相对于5-HT(K(i),2-乙基-5-甲氧基-N,N-二甲基色胺(8)以高亲和力结合人5-HT(6)受体(K(i)= 16 nM) )= 75 nM),并且在激活腺苷酸环化酶方面至少是与血清素(K(act)= 5.0 nM)一样有效的激动剂(8:K(act)= 3.6 nM)。化合物8对其他几个5-HT受体群体表现出适度的亲和力,尤其是h5-HT(1A)(K(i)= 170 nM),h5-HT(1D)(K(i)= 290 nM)和h5 -HT(7)(K(i)= 300 nM)受体,但否则具有选择性。化合物8代表迄今为止报道的第一个也是最具选择性的5-HT(6)激动剂。用苯基取代2-乙基取代基
