cell surface, herein we propose that the use of bifunctional inhibitors of this enzyme could represent an innovative approach to efficiently reduce tumor growth. A small series of symmetrical dimers derived from previously described monomeric arylsulfonamide hydroxamates was synthesized and tested in vitro on isolated MMPs. A nanomolar MT1-MMP inhibitor, compound 6, was identified and then submitted
胶原蛋白降解和proMMP-2激活是MT1-MMP促进癌细胞侵袭的主要功能。由于这两个过程都需要细胞表面上的 MT1-MMP 同二聚化,因此我们提出使用该酶的双功能抑制剂可以代表一种有效减少肿瘤生长的创新方法。合成了源自先前描述的单体芳基磺酰胺异羟肟酸盐的一小组对称二聚体,并在分离的 MMP 上进行了体外测试。鉴定出一种纳摩尔 MT1-MMP 抑制剂(化合物6),然后对 HT1080 纤维肉瘤细胞进行基于细胞的测定。二聚体6以剂量依赖性方式减少 MT1-MMP 依赖性 proMMP-2 激活、胶原蛋白降解和胶原蛋白侵袭,甚至与其单体类似物相比,效果更好4。这项初步研究表明二聚体 MT1-MMP 抑制剂可能会被进一步开发和利用作为减少癌细胞侵袭的替代工具。
