endothelial cells based on its ability to directly bind integrin alpha(V)beta(3), suggesting that disrupting this protein--protein interaction may represent a new target for the development of angiogenesis inhibitors. The screening of small molecule libraries led to the identification of compounds which disrupt the MMP2--alpha(V)beta(3) interaction in an in vitro binding assay. A prototypical inhibitor was
从现有脉管系统中生长新血管的过程,称为血管生成,对多种病理状况至关重要,最显着的是癌症。降解细胞外基质 (ECM) 的 MMP2 和有助于内皮细胞附着到 ECM 的整合素 alpha(V)beta(3) 都参与了这一过程。最近的研究结果表明,基于 MMP2 直接结合整合素 alpha(V)beta(3) 的能力,MMP2 以活性形式定位于侵袭性内皮细胞的表面,这表明破坏这种蛋白质 - 蛋白质相互作用可能代表一个新的目标用于血管生成抑制剂的开发。小分子库的筛选导致鉴定在体外结合测定中破坏 MMP2--alpha(V)beta(3) 相互作用的化合物。进一步发现原型抑制剂可防止蛋白质基质降解,而不会直接抑制 MMP2 活性或破坏 alpha(V)beta(3) 与其经典 ECM 配体玻连蛋白的结合。这种先导化合物的类似物和亚结构的合成和筛选允许鉴定抑制 MMP2 与 alpha(V)beta(3)
