A new series of [1,2,4]triazolo[1,5-a]pyrimidine-based LSD1 inhibitors were designed, synthesized, and further evaluated for their cytotoxicity against MGC-803, EC109, A549 and PC-9 cells as well as the ability of inhibiting LSD1. Some of these compounds showed potent inhibition toward LSD1 and selectively inhibited growth of A549 and PC-9 cells. Compound 6l potently inhibited growth of PC-9 cells
设计,合成了一系列新的基于[1,2,4]三唑[1,5-a]嘧啶的LSD1抑制剂,并进一步评估了它们对MGC-803,EC109,A549和PC-9细胞的细胞毒性作为抑制LSD1的能力。这些化合物中的一些显示出对LSD1的有效抑制作用,并选择性抑制A549和PC-9细胞的生长。化合物6l有效抑制PC-9细胞的生长(IC 50 = 0.59μM),效力比5-FU高约4倍。进一步的SAR研究导致鉴定了6l-m化合物,该化合物对所有测试的癌细胞系均具有良好的生长抑制作用,并且比5-FU和GSK2879552更有效。此外,化合物5p,5q和6i有效抑制LSD1(IC 50分别 为0.154、1.19和0.557μM)。对接研究表明,化合物5p与Val333形成了芳烃-H相互作用,并与周围的Ala331,Met332和Ala539残基形成氢键。化合物5p以浓度依赖的方式显着抑制A549和PC-9细胞
