when the substituents at 3 and 4 positions of the oxadiazine moiety adopt an α orientation (cf. 11). To address the concern around potential reactivity of the exocyclic double bond present in series I toward nucleophilic attack, compounds containing either an endocyclic double bond, such as 20 (series II), or devoid of an olefinic moiety, such as 27 (series III), were designed and validated as novel
在本文中,我们公开了基于恶二嗪支架的三种结构差异化的γ分泌酶调节剂(GSM)。当恶二嗪部分的3和4位上的取代基采用α方向时,系列I的类似物在体外有效抑制Aβ42的产生(参见11)。为了解决有关系列I中存在的环外双键对亲核攻击的潜在反应性的担忧,含有内环双键(例如20(系列II))或不含烯烃部分(例如27)(III系列)的化合物被设计和验证为新型GSM。化合物11和氮杂20显示出强大的降低CSF的Aβ 42 在口服剂量为30 mg / kg的大鼠中。
