8-deazatetrahydrofolates bearing electrophilic groups on N5 were designed and synthesized based on the action mechanism of methionine synthase, and their biological activities were investigated as well. Compounds (11b, 12b and 16) showed the most active against methionine synthase (IC50: 8.11 μM, 1.73 μM, 1.43 μM). In addition, the cytotoxicity to human tumor cell lines and dihydrofolate reductase (DHFR)
基于蛋氨酸合酶的作用机理,设计合成了许多在N 5上带有亲电基团的8-脱氮氢叶酸,并对其生物学活性进行了研究。化合物(11b,12b和16)对甲硫氨酸合酶表现出最强的活性(IC 50:8.11μM,1.73μM,1.43μM)。此外,还评估了目标化合物对人肿瘤细胞系的细胞毒性和二氢叶酸还原酶(DHFR)的抑制作用。
