role in hepatocyte growth factor (HGF) signaling and epithelial integrity makes it a target of therapeutic interest in carcinogenesis and metastasis. Using an integrated design, synthesis, and screening platform, we were able to rapidly develop potent and selective inhibitors of hepsin. In progressing from the initial hit 7 to compound 53, the IC50 value against hepsin was improved from ∼1 μM to 22
肝素是一种膜锚定的丝氨酸蛋白酶,其在肝细胞生长因子(HGF)信号传导和上皮完整性中的作用使其成为癌变和转移的治疗靶标。使用集成的设计,合成和筛选平台,我们能够快速开发出有效的和选择性的肝素抑制剂。从最初的命中7到化合物53的过程中,针对肝素的IC 50值从约1μM提高到22 nM,并且对尿激酶型纤溶酶原激活剂(uPA)的选择性从30倍增加至> 6000倍。随后的体外ADMET分析和细胞研究证实,领先的化合物是用于研究肝素在乳腺肿瘤发生中的作用的有用工具。
