3,4-disubstituted azetidinones as selective inhibitors of the cysteine protease cathepsin K. Exploring P2 elements for selectivity.
A novel series of 3,4-disubstituted azetidinones based inhibitors of the cysteine protease cathepsin K (Cat K) has been identified. Although not optimized, some of these compounds show at least 100-fold selectivity against other cathepsins. The use of cyclic moieties as P2 elements has proven to be crucial to achieve a high degree of selectivity.
