We designed and synthesized a series of N‐alkyl‐carbazoles with different alkyl chains and amine moieties, and biological evaluation was performed to discover novel 5‐HT7R antagonists. Among 27 synthesized compounds, 20, 21, 23, and 24 showed excellent binding affinities to 5‐HT7R (Ki = 65, 64, 55, and 31 nM, respectively), and good selectivity profiles over other serotonin receptors.

我们设计并合成了一系列具有不同烷基链和胺基团的N烷基咔唑,并进行了生物学评估以发现新型5 HT 7 R拮抗剂。间27个合成的化合物,20,21,23,和24显示出优异的结合亲和力到5-HT 7 R(ķ我= 65,64,55,和31 nM的,分别地),并用其他血清素受体良好的选择性概况。在功能测定中,那些化合物显示出对5-HT弱拮抗活性7 R.具体地,化合物24,将2-(4-(5-(9- ħ-咔唑-9-基)戊基)哌嗪-1-基)苯酚被认为是具有较强拮抗作用的强效选择性5-HT 7 R配体。从分子对接研究中,在芳香族羟基24示于结合5-HT发挥重要作用7通过在5-HT的配体结合口袋与Asp142氢键交互r 7 R.
