NCI-H460 (lung), HCT116 (colon), MCF7 (breast), PC3 (prostate), and HeLa (cervical) cells with IC50 values from 0.1 to 0.3 muM. 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
喹唑啉衍生物PVHD121(1a)已显示出对多种肿瘤衍生细胞系(包括A549(肺),NCI-H460(肺),HCT116(结肠),MCF7(乳腺),PC3(前列腺),和HeLa(子宫颈)细胞,IC50值为0.1至0.3μM。在喹唑啉核心的2位和4位进行的结构活性关系(SAR)研究导致发现了更有效的抗癌药(14、16、17、19、24和31)。体外微管蛋白聚合测定和纯化的微管蛋白的基于荧光的秋水仙碱位点竞争测定的结果表明1a通过与秋水仙碱位点结合来抑制微管蛋白聚合。
