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 C1-C3-alkyl, C1-C3-haloalkyl, C2-C4-alkenyl, C3-C6-cycloalkyl, C3-C6-cycloalkyl-C1-C2-alkyl, or phenyl-C1-C3-alkyl, 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.
本发明涉及新型羧酰胺化合物及其用于制备药物的用途。这些羧酰胺化合物是钙依赖性半胱氨酸蛋白酶(calpain)的抑制剂。因此,本发明还涉及使用这些羧酰胺化合物治疗与升高的calpain活性有关的疾病。这些羧酰胺化合物是通式I的化合物,在其中R1、R2、R3、R4、R5、m和n具有所述权利要求和描述中提到的含义,它们的互变异构体、水合物和药学上适宜的盐也属于本发明的保护范围。其中,偏好使用R1为可选取代的苯基-C1-C2-烷基或杂环基-C1-C2-烷基,R2为可选取代的芳基、杂环基、芳基-C1-C6-烷基、芳基-C2-C6-烯基或杂环基-C1-C4-烷基,R3为C1-C3-烷基、C1-C3-卤代烷基、C2-C4-烯基、C3-C6-环烷基、C3-C6-环烷基-C1-C2-烷基或苯基-C1-C3-烷基,R4和R5各自独立地为卤素、CF3、CHF2、CH2F、C1-C2-烷基或C1-C2-烷氧基,m和n各自独立地为0或1。
