and the substrate pocket, selective PRMT6 inhibitors have rarely been reported. In this study, a series of (5-phenylpyridin-3-yl)methanamine derivatives were designed and synthesized, which could form hydrogen bonding interactions with the unique Glu49 of PRMT6, thereby improving the selectivity of the compounds for PRMT6. Among them, a25 had the best activity and selectivity, with more than 25-fold
PRMT6是蛋白精氨酸甲基转移酶家族的一员,参与多种生理过程,在肿瘤的发生发展中起重要作用。由于Ⅰ型PRMT同源性高,SAM口袋和底物口袋两个紧密结合位点,选择性PRMT6抑制剂鲜有报道。本研究设计并合成了一系列(5-phenylpyridin-3-yl)methanamine衍生物,可与PRMT6独特的Glu49形成氢键相互作用,从而提高化合物对PRMT6的选择性。其中,a25具有最好的活性和选择性,对PRMT1/8的选择性超过25倍,对PRMT3/4/5/7的选择性超过50倍,优于这些报道的SAM竞争性和底物竞争性PRMT6抑制剂。重要的是,a25能显着抑制多种肿瘤细胞的增殖,有效诱导癌细胞凋亡。我们的数据表明a25是一种很有前途的选择性 PRMT6 癌症治疗抑制剂,值得进一步评估。
