  • Patent number: 6410580
    Abstract: Compounds of formula (I) wherein W is —OH or —NHOH; X is an optionally substituted heterocycle, NR1SO2R2, heterocyclylalkythio, CONR2R3 or NR1COR2; Y, Z, R1-R3 and n are as defined in the application. Compounds (I) are inhibitors of matrix-degrading metalloproteinases and are use for the treatment of related conditions.

  • Patent number: 6353017
    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.

  • Patent number: 6277987
    Abstract: Compounds of formula wherein W is —OH or —NHOH; X is a heterocycle with the proviso that when X is a nitrogen containing heterocycle, the heterocycle is attached to the (CH2)m moiety by a ring nitrogen, —CONR2R3, —NR1COR2, —NR1SO2R2, —NR1CONR2R3, —NR1COOR4, heteroarylthio, alkylthio, arylalkylthio, heteroarylalkylthio, heterocycloalkylalkylthio, heterocycloalkylthio or arylthio; Y is carbon, nitrogen, oxygen or sulfur, provided that when Y is carbon, n is 2; Z is alkyl, aryl, alkoxy, aryloxy, aralkoxyaryl, aralkoxyheteroaryl, heteroaryl, heterocycloalkyl, heteroaryloxy, —CONR2R3, —NR1COR2, —NR1CONR2R3, —OCONR2R3, —NR1COOR4, or —SO2R2; R1 is hydrogen, alkyl, heterocycloalkylalkyl, aralkyl or heteroarylalkyl; R2 and R3 are independently R1, aryl or heteroaryl; or R2 and R3 taken together with the nitrogen atom to which they are attached form a 5- to 7-membered ring, which may optionally contain another heteroat
