Patent ID: 7718815

Claim:
An α-aminoamide compound represented by the following formula (I): wherein: R is a furyl, thienyl, pyridyl ring or a phenyl ring, optionally substituted by one or two substituents independently selected from halogen, hydroxy, cyano, C 1 -C 6 alkyl, C 1 -C 6 alkoxy or trifluoromethyl; R 1 is hydrogen or C 1 -C 6 alkyl or C 3 -C 7 cycloalkyl; R 2 and R 3 are independently selected from hydrogen, C 1 -C 4 alkyl optionally substituted by hydroxy or phenyl, phenyl in which the phenyl rings being optionally substituted by one or two substituents independently selected from C 1 -C 6 alkyl, halogen, hydroxy, C 1 -C 6 alkoxy or trifluoromethyl; or R 2 and R 3 , taken with the carbon atom which they are linked to, form a C 3 -C 6 cycloalkyl ring; R 4 and R 5 are independently hydrogen, C 1 -C 6 alkyl or C 3 -C 7 cycloalkyl; or R 4 and R 5 , taken together with the nitrogen atom they are linked to, form a 5-7 atom saturated heterocyclic ring; X is O; and Y and Z taken together form a dihydrobenzofuran, having the following structure: and/or stereoisomers, mixtures, and pharmaceutically acceptable salts thereof.
