subsequently cyclised to obtain quinazolones 4, chlorinated 5, then hooked to various optically pure alpha-amino acids to have 4,6-disubstituted quinazoline derivatives 6. All the derivatives 6 are screened for anti-inflammatory and anti-cancer activity against U937 leukemia cell lines. Some of the compounds exhibited promising anti-cancer activity with reference to standard drug Etoposide.
考虑到NSAIDs的使用和改变的癌症发生率之间的联系以及在血管生成中COX-II的影响的证据越来越多,已经通过常规方法从邻氨基苯甲酸衍生物1开始合成了一系列新的4,6-二取代的喹唑啉衍生物。最初进行酰化,然后环化获得苯并恶嗪酮2,将其进一步用氨水处理,即可生成关键的中间体2取代的苯甲酰胺(3)。随后将产物环化,得到喹唑酮4,氯代5,然后钩接到各种光学纯的α-氨基酸上,以得到4,6-二取代喹唑啉衍生物6。对所有衍生物6进行抗炎和抗癌活性筛选U937白血病细胞系。
