series of 4-pyrazolyl-1,8-naphthalimide derivatives have been designed and facilely synthesized. For anticancer activity in vitro, most of the compounds were found to be more toxic against human mammary cancer cells (MCF-7) than human cervical carcinoma cells (Hela) and human lung cancer cells (A549). Compounds 4i, 4h, 4b and 4a showed improved cytotoxic activity against MCF-7 cells over amonafide, in
已经设计并容易地合成了一系列新颖的4-吡唑基-1,8-萘二甲酰亚胺衍生物。对于体外抗癌活性,发现大多数化合物对人乳腺癌细胞(MCF-7)的毒性比人宫颈癌细胞(Hela)和人肺癌细胞(A549)高。化合物4i,4h,4b和4a与阿莫那肽相比对MCF-7细胞表现出改善的细胞毒活性,尤其是化合物4i和4h,其对MCF-7细胞系的IC 50值分别为0.51μM和0.79μM 。4i的DNA结合特性通过紫外可见光谱,荧光和圆二色性(CD)光谱学和热变性进行了研究。结果表明,作为DNA嵌入剂的化合物4i显示出与CT-DNA的中等结合亲和力。
