Matrix metalloproteinases (MMPs), a family of zinc-containing endopeptidases, participate in many normal processes such as embryonic development and wound repair, and in many pathological situations such as cancer, atherosclerosis, and arthritis. Peptidomimetic MMP inhibitors were designed and synthesized with N-formylhydroxylamine (retrohydroxamate) as a zinc-binding group and various side chains on the $\alpha}$, P1', and P2' positions. Using in vitro MMP assays with purified MMPs (MMP-1, MMP-2, MMP-3, MMP-9, and MMP-14) and fluorogenic peptide substrates, it was found that compounds 2d and 2g selectively inhibit gelatinases (MMP-2 and MMP-9) and interstitial collagenase (MMP-1). They also inhibited the chemo-invasion of fibrosarcoma HT-1080 cells and tube formation of human umbilical vascular endothelial cells in a dose-dependent manner. Our results suggest that retrohydroxamate-based MMP inhibitors, especially compounds 2d and 2g, have the potential to be used as therapeutic drugs for cancer and other MMP-related diseases.
基质金属蛋白酶(MMPs)是含锌内肽酶的一个家族,参与胚胎发育和伤口修复等许多正常过程,也参与癌症、动脉粥样硬化和关节炎等许多病理过程。我们设计并合成了拟肽MMP抑制剂,以N-甲酰羟胺(retrohydroxamate)作为锌结合基团,并在$\alpha}$、P1'和P2'位置上设计了不同的侧链。通过使用纯化的 MMP(MMP-1、MMP-2、MMP-3、MMP-9 和 MMP-14)和萤光肽底物进行体外 MMP 检测,发现化合物 2d 和 2g 能选择性地抑制明胶酶(MMP-2 和 MMP-9)和间质胶原酶(MMP-1)。它们还以剂量依赖的方式抑制了纤维肉瘤 HT-1080 细胞的化学侵袭和人脐血管内皮细胞的管形成。我们的研究结果表明,基于逆羟基甲酸酯的 MMP 抑制剂,尤其是化合物 2d 和 2g,有望用作癌症和其他 MMP 相关疾病的治疗药物。
