Matrix metalloproteinases (MMPs) play important roles in many diseases including cancer. With moderate metal-binding affinity, 8-hydroxyquinoline has gained much interest in current drug design and development. Specially, it has been reported that 8-hydroxyquinoline derivatives serve as MMP-2 inhibitors with micromolar IC50 values. In the current study, a series of 8-hydroxyquinoline derivatives were
基质金属蛋白酶(MMP)在包括癌症在内的许多疾病中都起着重要作用。具有适度的金属结合亲和力,8-羟基喹啉在当前的药物设计和开发中引起了很多兴趣。特别地,已经报道8-羟基喹啉衍生物用作具有微摩尔IC 50值的MMP-2抑制剂。在当前的研究中,设计并合成了一系列8-羟基喹啉衍生物,作为新的MMP-2和MMP-9抑制剂。活性最强的化合物5e和5h不仅对亚微摩尔水平的IC 50表现出对MMP-2 / 9的良好抑制活性,而且在A549细胞系中具有强大的抗增殖,抗侵袭和抗血管生成活性。免疫印迹也显示5e和5h下调A549细胞系中MMP-2和MMP-9的表达。此外,流式细胞术分析表明化合物5e可以促进A549细胞的体外凋亡。分子对接分析还揭示了MMP-2和MMP-9活性位点中5e的有利结合模式。
