including histone methylation and acetylation, and DNA methylation, are thought to play important roles in the onset and progression of cancer in numerous tumour cell lines. Lysine-specific demethylase 1 (LSD1 or KDM1A) is highly expressed in different cancer types and inhibiting KDM1A activity seems to have high therapeutic potential in cancer treatment. In the recent years, several inhibitors of KDM1A
表观遗传学的改变,包括组蛋白甲基化和乙酰化,以及DNA甲基化,被认为在许多肿瘤细胞系的癌症的发生和发展中起着重要的作用。赖氨酸特异性脱甲基酶1(LSD1或KDM1A)在不同类型的癌症中高度表达,抑制KDM1A活性似乎在癌症治疗中具有很高的治疗潜力。 近年来,已经制备并公开了几种KDM1A抑制剂。这些衍生物中的大多数是基于反式环丙胺的结构设计的,因为环丙烷核心负责抑制剂与KDM蛋白催化结构域之间的共价相互作用。在这项研究中,我们进一步扩展了关于化合物1a – e的SAR ,最近发现它们可抑制KDM1A并具有良好的活性。如化合物44a所示,在带有少量官能团的环丙烷环的β位置修饰苯环,这些官能团大多被卤化,尤其是在间位,导致对KDM1A的抑制活性显着提高。,其效力在低纳摩尔范围(31 nM)中。
