The synthesis of a series of novel N‐α‐galloylated isoglutamic acid γ‐amide peptidomimetics is described. Their enzymatic inhibition against aminopeptidase N (APN/CD13) and matrix metalloproteinase‐2 (MMP‐2) was tested. The preliminary activity assay revealed that most of the compounds displayed selective inhibition against APN as compared with MMP‐2, with IC50 values in a micromolar range. Within
描述了一系列新型 N-α-没食子酰化异谷氨酸 γ-酰胺肽模拟物的合成。测试了它们对氨肽酶 N (APN / CD13) 和基质金属蛋白酶 - 2 (MMP - 2) 的酶抑制作用。初步活性测定表明,与 MMP-2 相比,大多数化合物对 APN 表现出选择性抑制,IC50 值在微摩尔范围内。在这个系列中,化合物 4 (IC50 = 10.2 ± 0.9 µM) 与阳性对照巴伐他汀 (IC50 = 13.1 ± 0.7 µM) 相比表现出相当的 APN 抑制,这可能是进一步分子优化的一个有希望的线索。
