An efficient discovery strategy by combining diversity-oriented synthesis and converging cellular screening is described. By a three-round screening process, we identified novel tricyclic pyrido[2,3-b][1,4]benzothiazepines showing potent inhibitory activity against paclitaxel-resistant cell line H460TaxR (EC50 < 1.0 μM), which exhibits much less toxicity toward normal cells (EC50 > 100 μM against normal
描述了一种通过结合面向多样性的合成和融合细胞筛选的有效发现策略。通过三轮筛选过程,我们确定了新型三环吡啶并[2,3- b ] [1,4]苯并硫氮杂类对紫杉醇耐药细胞系H460 TaxR(EC 50 <1.0μM)表现出有效的抑制作用对正常细胞有毒性(对正常人成纤维细胞的EC 50 > 100μM)。最活跃的命中还显示出适合进一步临床前研究的类药物特性。抗抑郁化合物在抗癌应用中的这种重新部署为治疗具有较少副作用的耐药性肿瘤提供了有希望的未来前景。
