and low cytotoxicity, giving a markedly high therapeutic index. The chromone derivative specifically inhibited ABCG2 versus other multidrug ABC transporters and was not transported. It constitutes a highly promising candidate for in vivo chemosensitization of ABCG2-expressing tumors.
合成了一系列13个二取代色酮。在支架的每一侧上,两种类型的取代基对ABCG2抑制的效力和细胞毒性都有贡献。最好的化合物5-(4-溴苄氧基)-2-(2-(5-甲氧基吲哚基)乙基-1-羰基)-4 H-铬烯-4-酮(6g)具有高亲和力抑制作用和低细胞毒性,给出了很高的治疗指数。与其他多药ABC转运蛋白相比,色酮衍生物特异性抑制ABCG2且未被转运。它构成了对表达ABCG2的肿瘤进行体内化学增敏的高度有前途的候选者。
