A series of ketoamides were synthesized and evaluated for inhibitory activity against cathepsin K. Exploration of the interactions between achiral P(2) substituents and the cysteine protease based on molecular modelling suggestions resulted in potent cathepsin K inhibitors that demonstrated high selectivity versus cathepsins B, H, and L. Subsequent modifications of the P(3), P(1), and P(1') moieties
合成了一系列酮酰胺,并评估了其对组织蛋白酶K的抑制活性。基于分子建模建议,对非手性P(2)取代基与半胱氨酸蛋白酶之间相互作用的探索导致了强有力的组织蛋白酶K抑制剂,相对于组织蛋白酶B,H具有较高的选择性P.(3),P(1)和P(1')部分的后续修饰提供了口服生物利用的抑制剂。
