  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.

  peptidomimetics serve as biologically active compounds or as intermediates for other peptidyl isosteres. The N-terminal side of the C=C bond could be easily prepared in an optically pure form from α-amino acids. Synthesis of C-terminal building blocks in an optically pure form is more challenging. We developed a chemoenzymatic stereoselective approach to such optically active C-terminal building blocks to

  Antibody–drug conjugates (ADCs) have become an important therapeutic modality for oncology, with three approved by the FDA and over 60 others in clinical trials. Despite the progress, improvements in ADC therapeutic index are desired. Peptide-based ADC linkers that are cleaved by lysosomal proteases have shown sufficient stability in serum and effective payload-release in targeted cells. If the linker

  抗体-药物偶联物（ADC）已成为肿瘤学的重要治疗手段，其中三种已获得FDA批准，另外60多项已在临床试验中获得批准。尽管取得了进步，但仍需要改善ADC治疗指数。被溶酶体蛋白酶裂解的基于肽的ADC接头在血清中显示出足够的稳定性，并在靶细胞中有效释放有效负载。如果该接头可以被肿瘤特异性蛋白酶优先水解，则安全系数可能会提高。但是，基于肽的接头的使用限制了我们调节蛋白酶特异性的能力。在这里，我们报告新型非肽类ADC接头的结构指导发现。我们表明，含有环丁烷-1,1-二羧酸的连接子主要被组织蛋白酶B水解，而缬氨酸-瓜氨酸二肽连接子则不被水解。带有非肽接头的ADC在体内与具有二肽接头的ADC一样有效和稳定。我们的结果有力地支持了拟肽连接子的应用，并为改善ADC的选择性提供了新的机会。
