robust economic approach to N-(quinazoline-4-yl)sulfonamides was developed and synthesized different aryl, hetero aryl, alkyl and cyclopropyl sulfonamides in excellent yields. All the compounds were evaluated for cytotoxic affinity to SKOV3, DU145, THP1, U937, and COLO205 cell lines. Interesting to find that the bulkiness of substituent at C-2 position of quinazoline forces the molecule to flip around
开发了一种稳健的N-(喹唑啉-4-基)磺酰胺经济方法,并以优异的产率合成了不同的芳基,杂芳基,烷基和环丙基磺酰胺。评估所有化合物对SKOV3,DU145,THP1,U937和COLO205细胞系的细胞毒性亲和力。有趣的是,与先前已知的喹唑啉化合物的结合偏好相比,喹唑啉的C-2位取代基的庞大性迫使分子翻转以结合在活性位点上。在合成的21种化合物2b,2d,2e,2h,2i,3c,3d,3f,3g和3h中,发现在所有测试的细胞系中均具有活性,IC50值<10μg/ mL。进行对接模拟以了解各种C-2取代的喹唑啉磺酰胺的结合偏好。
