In an effort to develop potent and selective inhibitors toward ACAT2, structure-activity relationship studies were carried out using derivatives based on pyripyropene A (PPPA, 1). We have successfully developed novel PPPA derivatives with a 7-O-substituted benzoyl substituent that significantly exhibit more potent ACAT2 inhibitory activity and higher ACAT2 isozyme selectivity than 1.
为了开发针对 ACAT2 的有效且选择性抑制剂,我们使用基于吡嗪并吡喃酮 A(PPPA,1)的衍生物进行了构效关系研究。我们成功开发了具有 7-O-取代苯甲酰取代基的新型 PPPA 衍生物,与 1 相比,它们显著表现出更强的 ACAT2 抑制活性和更高的 ACAT2 同工酶选择性。
