New series of triazolo[4,3-c]quinazolines were designed, synthesized and their structures were elucidated using different spectroscopic techniques. They were evaluated for their in vitro antitumor activity against HepG2, MCF-7, PC-3, HCT-116 and HeLa cancer cell lines using MTT assay. It was found that all compounds showed variable in vitro cytotoxicity. Distinct derivatives exhibited higher inhibitory
设计,合成了新的三唑并[4,3-c]喹唑啉系列,并使用不同的光谱技术阐明了它们的结构。使用MTT测定法评估了它们对HepG2,MCF-7,PC-3,HCT-116和HeLa癌细胞系的体外抗肿瘤活性。发现所有化合物均显示出不同的体外细胞毒性。使用DOX标准,不同的衍生物对被测细胞系表现出更高的抑制活性,IC50值在8.27至10.68 µM之间(IC50 = 4.17-8.87 µM)。进行体外表皮生长因子受体(EGFR)抑制测定。结果显示,与参考药物吉非替尼(IC50 = 1.74 µM)相比,化合物8、19和21表现出有价值的EGFR抑制活性,IC50值为0.69至1.8 µM。进一步的研究表明,活性候选物8、19和21导致细胞周期停滞在G2 / M期,有趣的是,MCF-7细胞的凋亡诱导的细胞死亡累积分别为7.14、17.52和24.88%,而DOX为正面参考(29.09%)。还进行了分
