New series of pyrimido[4,5-b]quinolines and [1,2,4]triazolo[2′,3′:3,4]pyrimido[6,5-b]quinolines have been synthesized. Compounds 4a, 4e, 4f, 4h, 5b, 5d, 6a, 6d, 6e, 8c, 8d, 10c–e, 10h, 11a, 11b, and 12a were tested for in vitro antitumor activity against human breast carcinoma (MCF-7) cell line, where compound 8d was found to be the most active member with IC50 value of 3.62 μM. The DNA-binding affinity
合成了新系列的嘧啶并[4,5- b ]喹啉和[1,2,4]三唑并[2',3':3,4]嘧啶并[6,5- b ]喹啉。测试了化合物4a,4e,4f,4h,5b,5d,6a,6d,6e,8c,8d,10c – e,10h,11a,11b和12a对人乳腺癌的体外抗肿瘤活性(MCF-7 )细胞系,其中化合物8d是IC 50最活跃的成员值为3.62μM。对相同化合物的DNA结合亲和力表明化合物8d和10d表现出对DNA的最高亲和力。报告了详细的合成,光谱和生物学数据。
