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

Methylation of the peptide bond in model azadipeptides leads to the E configuration and hence to atropisomerism due to a restricted rotation around the N–N axis.
