type I PRMT inhibitors previously identified by us, allowed for the identification of potent and selective inhibitors of PRMT4, which regardless of the low cell permeability show an evident reduction of arginine methylation levels in MCF7 cells and a marked reduction of proliferation. We also report crystal structures with various PRMTs supporting the observed specificity and selectivity.
蛋白质精氨酸甲基转移酶 (PRMT) 是重要的治疗靶点,在许多细胞过程的调节中起着至关重要的作用,并与许多疾病有关。然而,关于它们的功能和它们所涉及的生物学途径,以及可能推动 PRMT 活性选择性调节剂发展的结构要求,仍有许多有待了解。在这里,我们报告了一种解构-重建方法,该方法从我们之前鉴定的一系列 I 型 PRMT 抑制剂开始,允许鉴定 PRMT4 的有效和选择性抑制剂,无论细胞渗透性低如何,都显示精氨酸甲基化明显减少MCF7 细胞中的水平和增殖的显着减少。
