BioAssay: AID 609669

Inhibition of human cathepsin S using Z-Lys-Gln-Lys-Leu-Arg-AMC as substrate after 1 hr by fluorescence assay

A series of azepanone inhibitors of cathepsin S is described. Selectivity over both cathepsin K and cathepsin L was achieved by varying the P2 substituent. Ultimately, a balanced potency and selectivity profile was achieved in compound 39 possessing a 1-methylcyclohexyl alanine at P2 and nicotinamide as the P' substituent. The cellular potency of selected analogs is also described. ..more

Title: Azepanone-based inhibitors of human cathepsin S: optimization of selectivity via the P2 substituent.

Abstract: A series of azepanone inhibitors of cathepsin S is described. Selectivity over both cathepsin K and cathepsin L was achieved by varying the P2 substituent. Ultimately, a balanced potency and selectivity profile was achieved in compound 39 possessing a 1-methylcyclohexyl alanine at P2 and nicotinamide as the P' substituent. The cellular potency of selected analogs is also described.
