Carboxamide compounds and their use as calpain inhibitors v

Abstract

The present invention relates to novel carboxamide compounds and their use for the manufacture of a medicament. The carboxamide compounds are inhibitors of calpain (calcium dependant cysteine proteases). The invention therefore also relates to the use of these carboxamide compounds for treating a disorder associated with an elevated calpain activity. The carboxamide compounds are compounds of the general formula (I) in which R, Rand n have the meanings mentioned in the claims and the description, Y is a radical of the formulae (Y1) or (Y2) where # indicates the point of attachment of Y to the pyridine ring, R, R, R, Rand m have the meanings mentioned in the claims and the description, A is (CH)with p being 1, 2, 3 or 4, where one or two hydrogen atoms may be replaced by a radical R, where A is attached to the 3- or 4-position of the pyrazole radical and Rhas the meaning mentioned in the claims and the description; Ais (CH)q with q being 0, 1, 2 or 3, where one or two hydrogen atoms may be replaced by halogen or C-C-alkyl; and Ais (CH)r with r being 0, 1, 2 or 3, where one or two hydrogen atoms may be replaced by halogen or C-C-alkyl, provided that that r+q is 2, 3, 4, 5 or 6; their tautomers, the hydrates thereof, the pharmaceutically suitable salts of the carbox-amide compounds (I), the prodrugs of (I) and the pharmaceutically suitable salts of the prodrugs, tautomers or hydrates of (I).
