Matrix metalloproteinase-13 (MMP-13) is a zinc-dependent protease responsible for the cleavage of type II collagen, the major structural protein of articular cartilage. Degradation of this cartilage matrix leads to the development of osteoarthritis. We previously have described highly potent and selective carboxylic acid containing MMP-13 inhibitors; however, nephrotoxicity in preclinical toxicology
基质金属蛋白酶-13(MMP-13)是锌依赖性蛋白酶,负责II型胶原蛋白的切割,II型胶原蛋白是关节软骨的主要结构蛋白。该软骨基质的降解导致骨关节炎的发展。先前我们已经描述了高效且选择性的含MMP-13抑制剂的羧酸。然而,临床前毒理学种类中的肾毒性阻止了其发展。据推测,由人类有机阴离子转运蛋白3(hOAT3)介导的化合物在肾脏中的积累是这一发现的一个促成因素。在此,我们报告了我们为优化非羧酸铅的MMP-13效力和药代动力学特性所做的努力,从而鉴定了化合物43a 在可比的暴露水平下缺乏先前观察到的临床前毒理学。
