Anti-apoptotic Bcl-2 family proteins are vital for cancer cells to escape apoptosis, which make them attractive targets for cancer therapy. Recently, a lead compound 1 was found to modestly inhibit the binding of BH3 peptide to Bcl-2 protein with a Ki value of 5.2 µM. Based on this, a series of substituted tyrosine derivatives were developed and tested for their binding affinities to Bcl-2 protein
抗凋亡的Bcl-2家族蛋白对于癌细胞逃避凋亡至关重要,这使其成为癌症治疗的有吸引力的靶标。最近,发现前导化合物1以5.2μM的K i值适度抑制BH3肽与Bcl-2蛋白的结合。基于此,开发了一系列取代的酪氨酸衍生物,并测试了它们与Bcl-2蛋白的结合亲和力。结果表明,这些化合物表现出强效的结合亲和力的Bcl-2和Mcl-1蛋白但不与Bcl-X大号蛋白。可能是化合物6i用K i抑制了BH3肽与Bcl-2和Mcl-1蛋白的结合 分别为450和190nM的值,并且显示出对测试的癌细胞明显的抗增殖活性。
