摘要
Matriptase is a member of the type II transmembrane serine protease family. Several studies have reported deregulated matriptase expression in several types of epithelial cancers, suggesting that matriptase constitutes a potential target for cancer therapy. We report herein a new series of slow, tight binding inhibitors of matriptase, which mimic the P1-P4 substrate recognition sequence of the enzyme. Preliminary structure-activity relationships indicate that this benzothiazole-containing RQAR-peptidomimetic is a very potent inhibitor and possesses a good selectivity for matriptase versus other serine. proteases. A molecular model was generated to elucidate the key contacts between inhibitor 1 and matriptase.
