Quinazolines and 1,2,4-triazoles are important class of nitrogen containing heterocyclic compounds having immense biological importance. From the literature review, pharmacokinetic properties of a drug can be modified or enhanced by building a triazole moiety into a compound like quinazoline. Therefore, the study of new hybrid systems which combines triazole system with quinazoline is still seemed warranted. In the present study, a sequence of novel 1,2,4-triazole derivatives containing quinazolinyl moiety were designed, synthesized and screened for their in vitro anticancer activity. Thirteen new hybrids are synthesized from readily accessible 5-bromoanthranilic acid. All the hybrid compounds were well explicated by IR, 1H, 13C NMR, and mass spectral data. Out of 13, some of the compounds manifested moderate to good antiproliferative activity against two cancer cell lines (HepG2 and MCF7). Remarkably, compounds 8A, 16H and 16K displayed potent activity (14- 49 µM) on both HepG2 (liver carcinoma) and MCF-7 (breast cancer) cell lines whereas compounds 8B, 8F, 16L, and 15 displayed substantial activity against HepG2 cancer cell line (34-65 µM). Synthetic approach described here is very simple and can be used for the syntheses of related compounds library which is useful for the exploration of further biological activities and is currently underway in our laboratory
喹唑啉和1,2,4-三唑是一类重要的含氮杂环化合物,具有巨大的生物学重要性。根据文献综述,药物的药代动力学性质可以通过将三唑基团引入喹唑类化合物中来进行改性或增强。因此,研究将三唑系统与喹唑结合的新型混合系统仍然具有重要意义。在本研究中,设计、合成并筛选了一系列新型含喹唑基团的1,2,4-三唑衍生物,用于体外抗癌活性评价。从易获得的5-溴邻氨基苯甲酸合成了十三个新的混合物。所有混合物都通过红外光谱、核磁共振氢谱、核磁共振碳谱和质谱数据得到了很好的解释。在这13种化合物中,一些化合物对两种癌细胞系(HepG2和MCF7)表现出中等到良好的抗增殖活性。值得注意的是,化合物8A、16H和16K对HepG2(肝癌)和MCF-7(乳腺癌)细胞系均显示出强效活性(14-49 µM),而化合物8B、8F、16L和15对HepG2癌细胞系表现出显著活性(34-65 µM)。本文描述的合成方法非常简单,可用于相关化合物库的合成,有助于进一步探索生物活性,目前正在我们的实验室进行中。
