The nitrile warhead used in a series of cathepsin K inhibitors can be replaced by a less electrophilic primary amide. The accompanying loss of potency can be partially recovered by introducing a substituent α to the amide. The potency gain resulting from this addition is not achieved with the nitrile derivatives due to a different geometry of the cysteine adduct in the enzyme active site. This study led to the identification of the primary amide 2g, which is an inhibitory substrate, with an IC50 of 10 nM against cathepsin K and excellent selectivity versus the other cathepsins.

Based on our previous study with trifluoroethylamine as a P2-P3 amide isostere of cathepsin K inhibitor, further optimization led to identification of compound 22 (L-873724) as a potent and selective non-basic cathepsin K inhibitor. This compound showed e
