Structural Optimization of Azadipeptide Nitriles Strongly Increases Association Rates and Allows the Development of Selective Cathepsin Inhibitors
摘要:
Using the example of cathepsin K, we demonstrate the design of highly potent and selective azadipeptide nitrite inhibitors A systematic scan with respect to P2 and P3 substituents was carried out Structural modifications strongly affected the enzyme-inhibitor association (but not dissociation) rate A combination of optimized P2 and P3 substituents with a methylation of the P3-P2 amide linker resulted in the picomolar cathepsin K inhibitor 19 with remarkable selectivity over cathepsins L, B, and S
A tough nut to crack: In contrast to azadipeptidenitriles containing a P2 leucine residue, the synthesis of the corresponding homocycloleucine‐based inhibitors was more difficult; possibly due to the gem‐dialkyl effect. A synthetic route to the first homocycloleucine‐derived azadipeptidenitriles as selective and highly potent cathepsin K inhibitors is presented (see scheme).

A new approach to the synthesis of 4and 3-(5-R-1,2,4-oxadiazol-3-yl)benzoic acids via a selective oxidation of 5-R-3-tolyl-1,2,4-oxadiazoles with air oxygen in the presence of a catalytic system based on cobalt acetate was suggested. This synthesis allowed us to obtain the products in higher yields and with shorter sequence of steps as compared to the known procedures.
