By conducting a structureâactivity relationship study of the backbone of a series of oligoamide-foldamer-based α-helix mimetics of the Bak BH3 helix, we have identified especially potent inhibitors of Bcl-xL. The most potent compound has a Ki value of 94 nM in vitro, and single-digit micromolar IC50 values against the proliferation of several Bcl-xL-overexpressing cancer cell lines.
通过对一系列基于寡酰胺-折叠酰胺的 Bak BH3 螺旋δ-螺旋模拟物的骨架进行结构活性关系研究,我们发现了特别有效的 Bcl-xL 抑制剂。最有效的化合物在体外的 Ki 值为 94 nM,对几种 Bcl-xL 表达量过高的癌细胞株的增殖的 IC50 值为个位数微摩尔。
