Synthesis and cytotoxicity of 11 4-methylene pyrido[4,3-d]pyrimidines 5a–k were described. Cytotoxicity assay results showed that some compounds had much stronger antitumor activity than Fluorouracil against KB cell lines. The most active compound 5i exhibited high potency against KB, CNE2, MGC-803 cell lines with IC50 values of 0.48, 0.15, 0.59 μM, respectively. The preliminary structure–activity
描述了11种4-亚甲基吡啶并[4,3- d ]嘧啶5a – k的合成和细胞毒性。细胞毒性试验结果表明,某些化合物对氟尿嘧啶对KB细胞系的抗肿瘤活性强于氟尿嘧啶。最具活性的化合物5i对KB,CNE2,MGC-803细胞系表现出高效力,IC 50值分别为0.48、0.15、0.59μM。初步的结构-活性关系表明,带有带给电子功能基团的苄基的引入对该活性是有利的。
