Abstract

A quinazoline derivative PVHD121 (1a) was shown to have strong antiproliferative activity against various tumor-derived cell lines, including A549 (lung), NCI-H460 (lung), HCT116 (colon), MCF7 (breast), PC3 (prostate), and HeLa (cervical) cells with IC50 values from 0.1 to 0.3 μM. A structure-activity relationship (SAR) study at the 2- and 4-position of the quinazoline core lead to the discovery of more potent anticancer agents (14, 16, 17, 19, 24, and 31). The results of an in vitro tubulin polymerization assay and fluorescent-based colchicine site competition assay with purified tubulin indicated that 1a inhibits tubulin polymerization by binding to the colchicine site.

摘要

喹唑啉衍生物PVHD121(1a)对多种肿瘤来源的细胞系具有很强的抗增殖活性,包括A549(肺癌)、NCI-H460(肺癌)、HCT116(结肠癌)、MCF7(乳腺癌)、PC3(前列腺癌)和HeLa(宫颈癌)细胞,IC50值为0.1至0.3μM。对喹唑啉核心2位和4位的构效关系(SAR)研究导致发现了更有效的抗癌剂(14、16、17、19、24和31)。用纯化微管蛋白进行的体外微管蛋白聚合测定和基于荧光的秋水仙碱位点竞争测定结果表明,1a通过与秋水仙碱位点结合来抑制微管蛋白聚合。
