A series of quinoxalinone peptidomimetic derivatives was designed, synthesized, and assayed for their inhibitory activities on metalloproteinase-2 (MMP-2) and aminopeptidase N (APN). The results showed that all of these quinoxalinone derivatives displayed highly selective inhibition against MMP-2 as compared with APN, with IC(50) values in the micromole range. Compound A3 showed comparable MMP-2 inhibitory activities than the positive control LY52, which might be used as a potential lead in future research on anticancer agents.
设计、合成了一系列喹喔啉酮肽模拟衍生物,并对其抑制金属蛋白酶-2(MMP-2)和氨基肽酶 N(APN)的活性进行了测定。结果表明,与 APN 相比,所有这些喹喔啉酮衍生物均对 MMP-2 表现出高度选择性抑制,IC50 值在微摩尔范围内。化合物 A3 表现出与阳性对照物 LY52 相当的 MMP-2 抑制活性,可能作为未来抗癌药物研究的潜在先导化合物。
