USP7 has been regarded as a potential drug target for cancer therapy. Inhibitors of USP7 have been recently shown to suppress tumor cell growth in vitro and in vivo. Based on leading USP7 inhibitors P5091 and P22077, we designed and synthesized a series of thiazole derivatives. The results of in vitro assays showed that the thiazole compounds exhibited low micromolar inhibition activity against both
疱疹病毒相关的泛素特异性蛋白酶(HAUSP,也称为USP7)与Mdm2相互作用并使其稳定,并且是使泛素化致癌蛋白的第一个实例。USP7被认为是潜在的癌症治疗药物靶标。最近已经证明USP7的抑制剂在体外和体内抑制肿瘤细胞的生长。基于领先的USP7抑制剂P5091和P22077,我们设计并合成了一系列噻唑衍生物。体外测定的结果表明,噻唑类化合物对USP7酶和癌细胞系均表现出较低的微摩尔抑制活性。该化合物以p53依赖性和p53非依赖性方式诱导细胞死亡。两者合计,这项研究可能会提供噻唑化合物作为一类新的USP7抑制剂。
