develop potent and selective inhibitors toward ACAT2, structure–activity relationship studies were carried out using derivatives based on pyripyropene A (PPPA, 1). In particular, we investigated the possibility of introducing appropriate 1,11-O-benzylidene and 7-O-substituted benzoyl moieties into PPPA (1). The new o-substituted benzylidene derivatives showed higher selectivity for ACAT2 than PPPA
为了开发针对ACAT2的有效和选择性抑制剂,使用了基于吡啶并戊二烯A(PPPA,1)的衍生物进行了结构-活性关系研究。尤其是,我们研究了将适当的1,11- O-亚苄基和7- O-取代的苯甲酰基部分引入PPPA(1)的可能性。新的邻位取代的亚苄基衍生物对ACAT2的选择性高于PPPA(1)。其中,1,11- ö - ö -methylbenzylidene -7- ø - p -cyanobenzoyl PPPA衍生物7Q和1,11- ö - ö,邻-二甲基亚苄基-7-邻-对-氰基苯甲酰基PPPA衍生物7z被证明是有效的ACAT2抑制剂,具有前所未有的高同工酶选择性。
