were introduced, and systematic fluorine, bromine, and phenyl scans for phenylalanine in the P2 position were performed. Moreover, the N-terminal protection was varied. Kinetic investigations were carried out with cathepsin L, S, and K as well as papain. Changes in the backbone structure of the parent N-(tert-butoxycarbonyl)-phenylalanyl-glycine-nitrile (16), such as the introduction of an R-configured

A peptidyl nitrile of the general formula (I) or a pharmaceutically acceptable salt or prodrug thereof, is capable of selectively inhibiting dipeptidyl-peptidase I (DPP-I), also known as cathepsin C. A compound of the invention is useful as an active substance for the treatment of inflammation, type 2 diabetes, asthma, severe influenza, respiratory syncytial virus infection, CD8 T cell inhibition, inflammatory bowel diseases, psoriasis, atopic dermatitis, Papillon Lefevre syndrome, Haim Munk syndrome, gun disease, periodontitis, rheumatoid arthritis, Huntington’s disease, Chagas’ disease, Alzheimer’s disease, sepsis or for application in target cell apoptosis.

The present invention is directed to cyanomethyl derivatives that are inhibitors of cysteine protease, in particular, cathepsin B, K, F, and S and are therefore useful in treating diseases mediated by these proteases. The present invention is directed to pharmaceutical compositions comprising these compounds and processes for preparing them.
Total syntheses of (+)-cinereain and (−)-janoxepin, two fungal cyclotripeptides featuring a complex heterocyclic core and interesting phytotoxic and antimalarial activities, have been achieved in a highly convergent manner. In the keystep, a one-pot cascade initiated by fragment coupling (cyclocondensation) was followed by a spontaneous retro-Claisen rearrangement to afford a 2,5-dihydrooxepin-fused
