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 alpha 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
This invention relates to S-alkylcysteines and processes for preparing same. The compounds according to this invention are expected to be applicable as therapeutic agents for hepatic failures.
