Abstract

In this letter we report first nonpeptide inhibitors of hepatocyte growth factor (HGF) activation. These compounds inhibit the three proteases (matriptase, hepsin, and HGF activator) required for HGF maturation. We show that 6, 8a, 8b, and 8d block activation of fibroblast-derived pro-HGF, thus preventing fibroblast-induced scattering of DU145 prostate cancer cells. Compound 6 (SRI 31215) is very soluble (91 μM) and has excellent microsome stability (human t 1/2 = 162 min; mouse t 1/2 = 296 min). In mouse 6 has an in vivo t 1/2 = 5.8 h following IV administration. The high solubility of 6 and IV t 1/2 make this compound a suitable prototype "triplex inhibitor" for the study of the inhibition of HGF activation in vivo.

摘要

在本信函中,我们报道了肝细胞生长因子(HGF)激活的首批非肽类抑制剂。这些化合物抑制HGF成熟所需的三种蛋白酶(matriptase、hepsin和HGF激活剂)。我们表明,6、8a、8b和8d可阻断成纤维细胞衍生的前HGF的激活,从而防止成纤维细胞诱导的DU145前列腺癌细胞散射。化合物6(SRI 31215)具有很高的溶解度(91 μM),并且具有出色的微粒体稳定性(人t1/2 = 162分钟;小鼠t1/2 = 296分钟)。在小鼠体内,静脉注射后6的体内t1/2 = 5.8小时。6的高溶解度和静脉注射t1/2使其成为用于体内研究HGF激活抑制的合适的原型“三联体抑制剂”。
