摘要:

作者基于课题组先前得到的具有较强α7烟碱型乙酰胆碱受体I型正向变构调节剂活性的先导化合物2, 设计并合成了一系列的6位取代的3H-喹唑啉-4-酮化合物(3a3d), 所有目标化合物均通过对表达有人源α7乙酰胆碱受体的非洲爪蟾卵使用双电极电压钳技术来进行活性评价。然而, 100 μM的乙酰胆碱作用下, 所有化合物均没有显示出比先导化合2更高的活性。由此证明噻唑[4,5-d]并嘧啶-7(6H)-酮母核是发挥正向变构调节活性的必需基团, 是对先导化合物2的构效关系的补充。

Abstract:

A series of new 6-substituted 3H-quinazolin-4-ones (3a3d) were designed, synthesized and evaluated as the type I positive allosteric modulators (PAMs) of human α7 nAChR expressed in Xenopus ooctyes by two-electrode voltage clamp. However, no compound showed a better efficacious PAM than lead compound 2 in the presence of acetylcholine (100 μM). The structure-activity relationship (SAR) analysis suggested that thiazolo[4,5-d]pyrimidin-7(6H)-one was the key biological skeleton. 

Key words: 3H-Quinazolin-4-ones, α7 nAChR, Positive allosteric modulators, Structure-activity relationship, Schizophrenia disease
