covalent inhibitors, a strategy is to fill its large catalytic cleft by designing tranylcypromine (TCP) analogs decorated with long, hindered substituents. We prepared three series of TCP analogs, carrying aroyl- and arylacetylamino (1 a-h), Z-amino acylamino (2 a-o), or double-substituted benzamide (3 a-n) residues at the C4 or C3 position of the phenyl ring.

LSD1是赖氨酸脱甲基酶,高度参与癌症的发生和发展。为了设计高效的共价抑制剂,一种策略是通过设计装饰有长位受阻取代基的反式环丙胺(TCP)类似物来填补其大的催化裂隙。我们制备了三个系列的TCP类似物,在苯环的C4或C3位置带有芳酰基和芳基乙酰氨基(1 ah),Z-氨基酰基氨基(2 ao)或双取代的苯甲酰胺(3 an)残基。还制备了通过化学操作施加到TCP支架上的其他片段(化合物4ai)。当针对LSD1进行测试时,大多数1和3表现出的IC50值在低纳摩尔范围内,而1 e和3 a,d,f,g对单胺氧化酶的选择性也最高。在MV4-11 AML和NB4 APL细胞中,化合物3最有效,对两种细胞系(3a)或NB4细胞(3c)都表现出亚微摩尔细胞生长抑制作用。细胞测定中最有效的化合物还能够诱导LSD1靶基因(如GFI-1b,ITGAM和KCTD12)的表达,作为抑制LSD1的功能性读数。小鼠和人类的固
