Four series of acid amides were synthesized, and through measurement using a fluorogenic substrate assay with human recombinant MMP-1, MMP-2 and MMP-9, compound 3f showed considerable inhibitory activities against MMP-2, MMP-9 and the best selectivity over MMP-1. Preliminary structure–activity relationship analysis indicated that caffeic acid amides with electron-donating groups at para-position of
合成了四个系列的酰胺,并通过使用荧光底物测定法与人重组MMP-1,MMP-2和MMP-9进行测量,化合物3f对MMP-2,MMP-9表现出相当大的抑制活性,并且选择性优于MMP-1。初步的结构-活性关系分析表明,在氨基苯基对位具有供电子基团的咖啡酰胺比具有吸电子基团的酰胺具有更好的抑制活性和选择性,并且在咖啡酰基中相邻的二羟基的存在非常多。对于MMP-2和MMP-9抑制活性很重要。
