Abstract: N-terminal substituted dipeptide nitriles as defined are useful as inhibitors of cysteine cathepsins, e.g. cathepsins B, K, L and S, and can be used for the treatment of cysteine cathepsin dependent diseases and conditions, including inflammation, rheumatoid arthritis, osteoarthritis, osteoporosis, tumors (especially tumor invasion and tumor metastasis), coronary disease, atherosclerosis (including atherosclerotic plaque rupture and destabilization). Particular dipeptide nitriles are compounds of formula I, or physiologically-acceptable and -cleavable esters or a salts thereof wherein: the symbols are as defined. In particular it has been found that by appropriate choice of groups R, R2, R3, R4, R5, X1, Y and L, the relative selectivity of the compounds as inhibitors of the various cysteine cathepsin types, e.g. cathepsins B, K, L and S may be altered, e.g. to obtain inhibitors which selectively inhibit a particular cathepsin type or combination of cathepsin types.

Abstract: The current invention concerns the use of a receptor from the RZR/ROR receptor family or of a functional fragment thereof in a test of a compound for anti-autoimmune, anti-arthritic, anti-tumor, melatonin-like and/or melatonin-antagonistic activity and the production of a receptor ligand complex comprising said receptor or a functional fragment thereof and a ligand of said receptor. Described is also a method for testing compounds for said activity (screening for ligands) and the active compounds identified therewith.
