Set7/9 is a histone lysine methyltransferase, but it is also thought to be involved in a wide variety of pathophysiological functions. We previously identified cyproheptadine, which has a characteristic butterfly-like molecular conformation with bent tricyclic dibenzosuberene and chair-form N-methylpiperidine moieties, as a Set7/9 inhibitor. In this work, we synthesized several derivatives in order to
Set7 / 9是组蛋白赖氨酸甲基转移酶,但也被认为与多种病理生理功能有关。我们之前确定了赛庚啶,它具有Set7 / 9抑制剂,具有弯曲的三环二苯并亚戊烯和椅子状N-甲基哌啶部分,具有蝴蝶状分子构象。在这项工作中,我们合成了几种衍生物以检查空间结构与抑制活性的关系。我们发现,即使由于三环的10,11-烯烃键的减少或置换而导致的分子形状的微小变化,通常也会导致抑制活性的急剧降低。我们的结果不仅对开发更有效和选择性的抑制剂有用,而且对于新型抑制剂支架的构建也应是有用的。
