5-HT7R in RBA, in particular seven compounds (4, 5, 7, 8 and 10-12,Ki ≤ 10 nM). Antidepressant-like activity in vivo for all tested compounds (5-8) was confirmed. SAR analysis based on both crystallography-supported molecular modeling and RBA results indicated that mono-phenyl substituents at both hydantoin and piperazine are more favorable for 5-HT7R affinity than the di-phenyl ones.
本文提出了一种计算机辅助的洞察力,发现了铅结构5-(4-氟苯基)-3-(2-羟基-3-(4-(2-甲氧基苯基)哌嗪-1-)的新型类似物的受体-配体相互作用。 (yl)propyl)-5-methylimidazolidine-2,4-dione(1,MF-8),作为搜寻强效和选择性5-羟色胺5-HT7受体(5-HT7R)药物的一部分。设计并合成了新的乙内酰脲衍生物(4-19)。对于5-苯基-3-(2-羟基-3-(4-(2-乙氧基苯基)哌嗪-1-基)丙基)-5-甲基咪唑烷-2,4-二酮(4),通过实验确定了其晶体结构。进行了分子建模研究,包括药效团和基于结构的方法。在放射性配体结合测定法(RBA)中研究了新化合物对5-HT7R的亲和力以及对5-HT1AR,多巴胺D2R和α1-,α2-和β-肾上腺素受体的选择性。评价所选化合物(5-8)在小鼠体内的抗抑郁和抗焦虑作用。大多数测试化合物对RBA中
