我们先前报道的Bcl2/Bclxl抑制剂4有效地抑制了肿瘤的生长,但未能在体内实现完全消退。我们现在已经对它的吡咯核心结构进行了广泛的修改,最终发现了32(BM-1074)。化合物32与Bcl2和Bclxl蛋白结合,KI值为1 nM,对4种对有效和特异的Bcl2/BclxL抑制剂敏感的小细胞肺癌细胞系具有抑制癌细胞生长的作用,IC50值为1~2 nM。化合物32能够在体内以良好的耐受性剂量计划实现快速、完全和持久的肿瘤消退。化合物32是迄今为止报道的最有效的Bcl2/Bclxl抑制剂。
Our previously reported Bcl-2/Bcl-xL inhibitor, 4, effectively inhibited tumor growth but failed to achieve complete regression in vivo. We have now performed extensive modifications on its pyrrole core structure, which has culminated in the discovery of 32 (BM-1074). Compound 32 binds to Bcl-2 and Bcl-xL proteins with Ki values of < 1 nM and inhibits cancer cell growth with IC50 values of 1-2 nM in four small-cell lung cancer cell lines sensitive to potent and specific Bcl-2/Bcl-xL inhibitors. Compound 32 is capable of achieving rapid, complete and durable tumor regression in vivo at a well-tolerated dose-schedule. Compound 32 is the most potent and efficacious Bcl-2/Bcl-xL inhibitor reported to date.
