In this study, a series of amide derivatives were synthesized and evaluated for their S-adenosyl-L-homocysteine hydrolase (SAHase) inhibitory activities. The results demonstrated that most of compounds displayed potent SAHase inhibitory activities. Interestingly, compounds 11 and 14 exhibited more potent inhibitory effects than the aristeromycin, one of the most potent SAHase inhibitors known so far. Compounds 12, 13, 15 and 17 exhibited a moderate effect (IC50<10.0 µM). The structure–activity relationship found that compounds with substituted indazole-5-yl group at Ar position and ethylamino group at the side chain showed better SAHase inhibitory activities.
在本研究中,合成了一系列酰胺衍生物,并评估了其对S-腺苷- L-半胱氨酸水解酶(SAHase)的抑制活性。结果表明,大多数化合物表现出良好的SAHase抑制活性。有趣的是,化合物11和14的抑制效果比已知的最强SAHase抑制剂之一阿利斯霉素更强。化合物12、13、15和17表现出中等效应(IC50<10.0 µM)。结构-活性关系研究发现,在Ar位具有取代的吡唑-5-基团和侧链中的乙基氨基团的化合物显示出更好的SAHase抑制活性。
