cathepsin L. Starting from a known inhibitor of human cathepsin L, and guided by structure-based design, we were able to modulate the selectivity for Toxoplasma vs human CPL by nearly 50-fold while modifying physiochemical properties to be more favorable for metabolic stability and CNS penetrance. The overall potency of our inhibitors towards TgCPL was improved from 2 μM to as low as 110 nM and we successfully

For the purpose of elucidating the structural relationship between lathyrism and inhibition of necrosis induced by CCl4 in the liver of the rat, many compounds related to aminoacetonitrile were synthesized. N-Aminoacylaminoacetonitriles (VIII, XIV) were synthesized from phthaloylaminoacylaminoacetonitriles. VIII were converted to 2-hydroxyimino-5-oxopiperazine derivatives (XV) and 5-oxo-2-thio-piperazines (XX). Preparations of N-(N-acylaminoacyl) aminoacetonitriles were also described. Further, N-α-hydroxyacylaminoacetonitriles were prepared from chloralides of α-hydroxyacids with aminoacetonitrile. In addition, XV (R=H) was converted to 2-acetamino-5-acetoxypyrazine by treatment with acetic anhydride.

The present invention relates to compounds and compositions for treating diseases associated with cysteine protease activity. The compounds are reversible inhibitors of cysteine proteases S, K, F, L and B. Of particular interest are diseases associated with Cathepsin S. In addition this invention also discloses processes for the preparation of such inhibitors.
This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of cathepsins K, L, S and B. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.
