resistance has been a major threat in cancer therapies that necessitates the development of new strategies to overcome this problem. We report here a cell-based high-throughput screen of a library containing 2-million molecules for the compounds that inhibit the proliferation of non-small-cell lung cancer (NSCLC). Through the process of phenotypic screening, target deconvolution and structure-activity
耐药性一直是癌症治疗中的主要威胁,因此有必要开发新的策略来克服这一问题。我们在这里报告基于库的基于细胞的高通量筛选,该库包含200万个抑制非小细胞肺癌(NSCLC)增殖的化合物分子。通过表型筛选,靶标解卷积和结构-活性关系(SAR)分析过程,鉴定了一种基于呋喃并萘醌的小分子化合物AS4583,该化合物在对酪氨酸激酶抑制剂(TKI)敏感和对TKI耐药的NSCLC中表现出强效细胞(IC50 77 nM)和异种移植小鼠中。机理研究表明,AS4583通过破坏微染色体维持蛋白(MCM)复合物的形成来抑制细胞周期进程并减少DNA复制。
