indicated as a therapeutic target for cancer. To further establish the role of SIRT2 in cancers, it is necessary to develop selective and potent inhibitors. Here, we report the facile synthesis of novel lysine-derived thioureas as mechanism-based SIRT2 inhibitors with anticancer activity. Compounds AF8, AF10, and AF12 selectively inhibited SIRT2 with IC50 values of 0.06, 0.15, and 0.08 μM, respectively
Sirtuin 2(SIRT2)是一种蛋白质赖氨酸脱酰基酶,已被证明是癌症的治疗靶标。为了进一步确立SIRT2在癌症中的作用,有必要开发选择性和有效的抑制剂。在这里,我们报告新型赖氨酸衍生的硫脲作为具有抗癌活性的基于机制的SIRT2抑制剂的简便合成。化合物AF8,AF10和AF12选择性抑制SIRT2,IC50值分别为0.06、0.15和0.08μM。化合物AF8和AF10在癌细胞系中显示出广泛的细胞毒性,但在非癌细胞中毒性最小。AF8和AF10抑制人结肠直肠癌细胞HCT116的锚定非依赖性生长,GI50值约为7μM。此外,AF8在HCT116异种移植鼠模型中有效抑制了肿瘤的生长,
