A novel structural class of highly potent and selective 5-HT3 receptor antagonists is described. The compounds in this new series contain a thiazole moiety linking an aromatic group and a nitrogen-containing basic region; the thiazole group appears to be acting as a carbonyl bioisostere in this system. An optimized member of this series, 4-(2-methoxyphenyl)-2-[[4(5)-methyl-5(4)-imidazolyl]methyl]thiazole
描述了高效和选择性的5-HT 3受体拮抗剂的新型结构类别。这个新系列的化合物包含连接芳族基团和含氮碱性区域的噻唑部分;噻唑基似乎在该系统中充当羰基生物等排体。该系列的优化成员4-(2-甲氧基苯基)-2-[[[4(5)-甲基-5(4)-咪唑基]甲基]噻唑(5)在Bezold-Jarisch反射范例中表现出口服活性与标准药物恩丹西酮(1)和ICS-205-930(2)相当或更好。根据5-HT3受体结合的计算机药效团模型,合理化了一些构效关系。
