Inhibition of lysine specific demethylase 1 (LSD1) has been shown to induce the differentiation of leukemia stem cells in acute myeloid leukemia (AML). Irreversible inhibitors developed from the nonspecific inhibitor tranylcypromine have entered clinical trials; however, the development of effective reversible inhibitors has proved more challenging. Herein, we describe our efforts to identify reversible inhibitors of LSD1 from a high throughput screen and subsequent in silico modeling approaches. From a single hit (12) validated by biochemical and biophysical assays, we describe our efforts to develop acyclic scaffold-hops from GSK-690 (1). A further scaffold modification to a (4-cyanophenyl)glycinamide (e.g., 29a) led to the development of compound 32, with a Kd value of 32 nM and an EC50 value of 0.67 μM in a surrogate cellular biomarker assay. Moreover, this derivative does not display the same level of hERG liability as observed with 1 and represents a promising lead for further development.

（4-氰基苯基）甘氨酸衍生物作为赖氨酸特异性脱甲基酶1的可逆抑制剂的发展。
赖氨酸特异性脱甲基酶1（LSD1）的抑制作用已显示出可诱导急性髓细胞性白血病（AML）中白血病干细胞的分化。由非特异性抑制剂tranylcypromine开发的不可逆抑制剂已进入临床试验。然而，事实证明开发有效的可逆抑制剂更具挑战性。本文中，我们描述了我们从高通量筛选和随后的计算机模拟方法中鉴定LSD1可逆抑制剂的努力。从通过生物化学和生物物理分析验证的单次点击（12）中，我们描述了我们从GSK-690（1）开发无环棚架的努力。对（4-氰基苯基）甘氨酰胺（例如29a）的进一步支架修饰导致化合物的开发32，具有ķ d 32纳米的值与EC 50 0.67μM的替代蜂窝生物标志物测定值。而且，该衍生物显示出与1观察到的hERG责任水平不同，代表了进一步开发的有希望的线索。
