A novel synthetic protocol has been developed for the synthesis of 1,4-benzoxazinone-acetylphenylallyl quinazolin-4(3H)-one hybrids 7a–n by employing Pd-catalyzed CH arylation in presence of 5–10% phosphine ligand in good to excellent yields and evaluated for their anti-proliferative activity against three cancer cell lines such as A549 (lung), HeLa (cervical), MDA-MB-231 (breast). Compounds 7d, 7f
通过在5-10%膦配体存在的情况下采用Pd催化的C H芳基化反应,已开发出一种新颖的合成方案,用于合成1,4-苯并恶嗪酮-乙酰苯基烯丙基喹唑啉-4(3 H)-one杂化物7a - n。获得优异的收率,并评估了它们对三种癌细胞系(如A549(肺),HeLa(宫颈),MDA-MB-231(乳腺癌))的抗增殖活性。化合物7d,7f,7l和7n表现出令人鼓舞的抗增殖活性,GI 50值分别针对A549,HeLa和MDA-MB-231,范围为0.37至2.73 µM,而化合物7f表现出对GI 50值为0.58 µM的MDA-MB-231显着活性,7j表现为GI 50值为0.32 µM的对A549的显着活性,而7l表现为GI 50值为0.37 µM的对HeLa的显着活性。这是关于1,4-苯并恶嗪酮-乙酰苯基烯丙基喹唑啉-4(3 H)-一个杂种的合成和体外抗增殖评价的第一份报告。
