  Synthesis of Peptide Aldehyde Derivatives as Selective Inhibitors of Human Cathepsin L and Their Inhibitory Effect on Bone Resorption

  摘要：

  Cathepsin L, a lysosomal cysteine protease, is secreted by osteoclasts and participates in bone collagen degradation. In a search for cathepsin L inhibitors as antiosteoporotic agents, a series of peptide aldehyde derivatives were prepared by two synthetic approaches, DMSO oxidation of the corresponding alcohol derivatives and DIBAL-H reduction of the corresponding N,O-dimethylhydroxylamide derivatives, and evaluated for inhibitory activity against human cathepsin L and for inhibitory effects on bone resorption. Some of the peptide aldehyde derivatives including alpha-acylamino aldehyde derivatives showed potent activities. Among these compounds, N-(1-naphthalenylsulfonyl-L-isoleucyl-L-tryptophanal (12) was selected as a candidate for further investigation. Compound 12, a potent, selective, and reversible inhibitor of human cathepsin L with an IC50 Of 1.9 nM, inhibited the release of Ca2+ and hydroxyproline from bone in in vitro bone culture system and also prevented bone loss in ovariectomized mice at an oral dose of 50 mg/kg.

  摘要：

  报道了氟代烷基半缩醛与酮的一般有机催化不对称脱水曼尼希反应。在该曼尼希反应中，以前较少探索的芳基酮显示出很高的反应活性。通过这种有效的方法，直接获得了广泛的生物活性β-氨基酮。更重要的是，通过19 F NMR和HRMS分析检测并鉴定了参与反应的两种不同中间体。此外，通过生物活性的氟烷基β-氨基醇的合成证明了产物的合成效用。
