The invention relates to novel amidines and quanidines, the production and use thereof and the use thereof as trypsine-type serine protease competitive inhibitors, especially thrombine and compliment proteases CIs and C1r. The invention also relates to pharmaceutical compositions which contain said compounds as active ingredients, in addition to the use of the compounds as thrombine inhibitors, anticoagulants, compliment inhibitors and anti-inflammatory agents. The novel compositions are characterised by the linkage of a serine protease inhibitor having amidine or guanidine functions with an alkyl radical having two or more hydroxyl functions, whereby said alkyl radical is derived from sugar derivates. Several sugar structural components or components derived from sugar can therefore be linked to each other. Said principle of linking sugar derivates enables oral active compounds to be obtained.

摘要:
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 R1, R2, R3 R4, R5, m and n have the meanings mentioned in the claims and the description, the tautomers thereof, the hydrates thereof and the pharmaceutically suitable salts thereof. Of these compounds those are preferred wherein R1 is optionally substituted phenyl-C1-C2-alkyl or hetaryl-C1-C2-alkyl, R2 is optionally substituted aryl, hetaryl, aryl-C1-C6-alkyl, aryl-C2-C6-alkenyl or hetaryl-C1-C4-alkyl, R3 is C3-C4-alkyl, C1-C4-haloalkyl, C2-C4-alkenyl, C3-C6-cycloalkyl, C3-C6-cycloalkyl-C1-C2-alkyl, C3-C6-heterocycloalkyl-C1-C2-alkyl, phenyl-C1-C3-alkyl, pyridin-2-yl-C1-C3-alkyl or 1,3-benzoxazol-2-yl-methyl, R4 and R5 independently of one another are halogen, CF3, CHF2, CH2F, C1-C2-alkyl or C1-C2-alkoxy, and m and n independently of one another are 0 or 1.
