Patent ID: 6946483

Claim:
Benzofuran derivatives of general formula: and their pharmaceutically acceptable salts, in which: represents the —CH═CH— group or the group, A represents a linear or branched C 1 -C 3 alkylene group, T represents hydrogen or a C 1 -C 4 alkyl radical, R represents: the cyano, hydroxymethyl, formyl or tetrazolyl group, an ester group of general formula: in which R 4 represents a C 1 -C 6 alkyl or C 3 -C 6 cycloalkyl group, a carboxyl group of general formula: in which R 5 represents hydrogen or an alkali metal atom, an amide group of general formula: in which R 6 and R 7 , which are identical or different, represent hydrogen or a linear or branched C 1 -C 4 alkyl radical or R 6 and R 7 , when they are taken together, represent a C 2 -C 6 alkylene chain, a group of general formula: in which R 16 , R 17 and R 18 , which are identical or different, represent a linear or branched C 1 -C 4 alkylene group, R 1 represents hydrogen, a linear or branched C 1 -C 6 alkyl group, a C 3 -C 6 cycloalkyl group or a phenyl group, R 2 and R 3 , which are identical or different, represent hydrogen, a linear or branched C 1 -C 6 alkyl group or a C 3 -C 6 cycloalkyl group, W, W′ and Z are such that: when W represents CH and W′ represents C—R 8 , Z represents —CH═C—R 9 , R 8 and R 9 being identical or different and representing hydrogen, a halogen atom, a C 1 -C 4 alkyl radical, or a C 1 -C 4 alkoxy radical, X represents —O—, these benzofuran derivatives being in the form of individual isomers or of mixtures of the latter.
