member of anti-apoptotic Bcl-2 protein, myeloid cell leukemia sequence 1 (Mcl-1) protein is an attractive target for cancer therapy. In this study, a new series of pyrrolidine derivatives as Mcl-1 inhibitors were developed by mainly modifying the amino acid side chain of compound 1. Among them, compound 18 (Ki=0.077μM) exhibited better potent inhibitory activities towards Mcl-1 protein compared to positive
作为抗凋亡Bcl-2蛋白的重要成员,髓样细胞白血病序列1(Mcl-1)蛋白是癌症治疗的诱人靶标。在这项研究中,主要通过修饰化合物1的
氨基酸侧链,开发了一系列新的
吡咯烷衍
生物作为Mcl-1
抑制剂。其中,化合物18(Ki =0.077μM)对Mcl-1蛋白表现出更好的抑制活性。与阳性对照
棉酚相比(Ki =0.18μM)。此外,化合物40对PC-3细胞具有良好的抗增殖活性(Ki =8.45μM),与阳性对照
棉酚(Ki =7.54μM)相同。
