known crystal structure of a ketoamide-based inhibitor, information from residues that form the P2/P3 pocket was used in the design of inhibitors that could allow for gains in selectivity and potency. Further, incorporation of P' selective heterocycles, along with the P2/P3 modifications, is also described. These modifications have resulted in potent and selective cathepsin K inhibitors that allow for
组织蛋白酶K,木瓜蛋白酶超家族的溶酶体半胱氨酸蛋白酶,在破骨细胞中大量且选择性地表达,表明该酶对于骨吸收至关重要。通过抑制组织蛋白酶K来防止破骨细胞介导的骨吸收可能是预防骨质疏松的有效方法。在本研究中已经确定了有效的和选择性的可逆性基于酮酰胺的抑制剂。使用基于酮酰胺的抑制剂的已知晶体结构,可将形成P2 / P3口袋的残基信息用于抑制剂的设计中,以提高选择性和效价。此外,还描述了P′选择性杂环的掺入以及P2 / P3的修饰。
