affinity for Bcl-2 and Mcl-1 protein and show weaker activity against Bcl-XL protein. Based on the previous results, a new class of indole-3-carboxylic acid-based derivatives were designed and synthesized as Bcl-2/Mcl-1 dual inhibitors. Among them, compound 17 has a Ki value of 0.26μM for Bcl-2 protein and is better than WL-276. Furthermore, it inhibits the myeloid cell leukemia sequence 1 (Mcl-1) protein
B细胞淋巴瘤2(Bcl-2)家族蛋白是癌症治疗的诱人靶标。在我们以前的工作中,研究了WL-276的结构-活性关系。根据结果,若丹宁衍生物对Bcl-2和Mcl-1蛋白显示有效的结合亲和力,对Bcl-XL蛋白的活性较弱。基于先前的结果,设计并合成了新的一类基于吲哚-3-羧酸的衍生物作为Bcl-2 / Mcl-1双重抑制剂。其中,化合物17对Bcl-2蛋白的Ki值为0.26μM,优于WL-276。此外,它还可以抑制Ki值为72nM的髓样细胞白血病序列1(Mcl-1)蛋白。特别是化合物31可以选择性地作用于Bcl-2和Mcl-1蛋白,但不能选择性地作用于Bcl-XL蛋白,
