Consequently, a series of derivatives of the found hit 1d (N-[2-(dimethylamino)ethyl]-N-(2-phenylethyl)aniline) was synthesized. The most active 5-HT6/D2 ligands also showed affinity for 5-HT7R and 5-HT2AR. The para-chloroaniline derivative was identified as a potent dual 5-HT6/5-HT7 receptor antagonist (Ki = 24 nM and Kb = 30 nM, Ki = 4 nM and Kb = 1.4 nM, respectively). In the case of halogen-containing
通过与在第二个靶标上具有活性的化合物的相似性相结合的化学空间变窄与化学空间缩小相结合的新型杂化生物等排体生成/虚拟筛选方法已成功地用于开发结构新的双5-HT 6 / D 2受体配体。因此,合成了所发现的命中1d的一系列衍生物(N- [2-(二甲基氨基)乙基] -N-(2-苯基乙基)苯胺)。最活跃的5-HT 6 / d 2点的配体也显示出对5-HT 7 R和5-HT 2A R的对位-chloroaniline衍生物被鉴定为一种有效的双重5-HT 6 /5-HT7受体拮抗剂( K i = 24 nM和K b = 30 nM, K i = 4 nM和K b = 1.4 nM)。对于含卤素的化合物,在5-HT 6,D 2和5-HT 7受体上观察到了有趣的结构-活性关系,随后使用结合了量子极化的分子模型方法研究了配体-受体复合物配体对接(QPLD)和分子力学通用出生/表面面积(MM / GBSA)自由能计算,可以确定假定的卤素结合口袋。
