On the basis of structural analysis of dihydrofolate reductase (DHFR) (cocrystallized separately with NADPH, dihydrofolate and NADPH, trimethoprim), compounds 2 and 3 were optimized for inhibition of DHFR. Appreciable tumor growth inhibitory activities of compounds 2 and 3 over 60 human tumor cell lines were recorded. Combination of syringaldehyde and indole moieties in these two compounds was rationalized
根据二氢叶酸还原酶(DHFR)(与NADPH,二氢叶酸和NADPH,甲氧苄氨嘧啶分别共结晶)的结构分析,优化了化合物2和3对DHFR的抑制作用。记录了化合物2和3在60种人类肿瘤细胞系中的明显的肿瘤生长抑制活性。丁香醛和这两种化合物在吲哚部分的组合是由化合物的合成合理化4 - 7,10,和11,其被发现具有比化合物更少的肿瘤生长抑制活性2和3。此外,UV-vis和NMR光谱研究表明化合物2和3与DHFR有显着的相互作用,并且在这些化合物的存在下观察到其催化活性受到抑制。因此,修饰甲氧苄氨嘧啶是一种没有肿瘤生长抑制作用的抗菌药物,导致化合物2和3的开发具有明显的抗癌活性,这似乎是由于DHFR的抑制。
