potential target for cancer therapy, there are several SMYD2 inhibitors are reported, LLY-507 as a cell-active inhibitor exhibits submicromolar potency against SMYD2 in several cancer cell lines. To know which structural fragment of LLY-507 is suitable for chemical modification, three sites are chosen for structure–activity relationship studies (SARs). Among our focused library, compounds 43 and 44 with
据报道,含有SET和MYND结构域的蛋白质2(SMYD2)是赖氨酸甲基转移酶,可催化组蛋白和非组蛋白蛋白质上赖氨酸残基的甲基化。作为癌症治疗的潜在靶标,有几种SMYD2抑制剂被报道,作为细胞活性抑制剂的LLY-507在几种癌细胞系中对SMYD2表现出亚微摩尔的效力。为了知道LLY-507的哪个结构片段适合化学修饰,选择了三个位点用于结构-活性关系研究(SAR)。在我们的重点文库中,化合物43和44 在位点C具有酰胺键的化合物显示了合理改善的效力,表明对该片段的修饰更加灵活,并且在该位置引入亲电子战斗部可能为SMYD2提供了靶向赖氨酸的共价抑制剂。
