in-house compound library. Among the synthetic compounds, 9e was characterized as a potent LSD1 inhibitor with an IC50 of 1.230 μM and can inhibit the proliferation of THP-1 cells effectively. And most importantly, this is the first irreversible LSD1 inhibitor that is not derived from monoamine oxidase inhibitors. Hence, the discovery of 9e may serve as a proof of concept work for AML treatment.
赖氨酸特异性脱甲基酶1(LSD1),针对单和二甲基化组蛋白3赖氨酸4的脱甲基酶,已成为肿瘤学中有希望的靶标。更具体地说,已证明它是急性髓细胞性白血病(AML)的关键启动子,并且几种LSD1抑制剂已进入治疗AML的临床试验。在本文中,基于通过我们内部化合物库的高通量筛选获得的先导化合物,设计和合成了一系列新的吲哚衍生物。在合成化合物中,9e被表征为具有IC 50的有效LSD1抑制剂浓度为1.230μM,可有效抑制THP-1细胞的增殖。最重要的是,这是第一种不可逆的LSD1抑制剂,它不是单胺氧化酶抑制剂衍生的。因此,发现9e可以作为AML治疗的概念证明工作。
