Patent ID: 7354918

Claim:
A compound of formula (I) its isomers, enantiomers, diastereoisomers and mixtures thereof; wherein R represents an â€”ARâ€² radical, A represents an oxygen, sulphur, or nitrogen atom and Râ€² is selected from the group consisting of a) linear or branched C 1 -C 6 alkyl radicals, C 2 -C 6 alkenyl radicals and C 2 -C 6 alkynyl radicals and linear or branched arylalkyl, alkoxyarylalkyl, heteroarylakyl and heterocycloalkyl radicals, b) esters of the formula â€”R 1 â€”COâ€”Oâ€”R 2 , wherein R 1 represents a radical selected from the group consisting of linear or branched C 1 -C 6 alkylene radicals, C 2 -C 6 alkenylene radicals and C 2 -C 6 alkynylene radicals and R 2 represents a radical selected from the group consisting of hydrogen, linear or branched C 1 -C 6 alkyl radicals, C 2 -C 6 alkenyl radicals, C 2 -C 6 alkynyl radicals and C 3 -C 12 cycloalkyl radicals, c) amides of the formula wherein R 3 is selected from the group consisting of linear or branched C 1 -C 6 alkyl radicals, C 2 -C 6 alkenylene radicals and C 2 -C 6 alkynylene radicals wherein Y represents a radical selected from the group consisting of hydrogen, linear or branched C 1 -C 6 alkyl radicals, C 2 -C 6 alkenyl radicals and C 2 -C 6 alkynyl radicals and linear or branched aryl, arylalkyl, heteroarylalkyl and heterocycloalkyl radicals, wherein Z is selected from the group consisting of hydrogen, linear or branched C 1 -C 6 alkyl radicals, C 2 -C 6 alkenyl radicals and C 2 -C 6 alkynyl radicals and linear or branched aryl, arylalkyl, heteroarylalkyl and heterocycloalkyl radicals, provided that Y and Z together may form a C 3 -C 6 cycloalkyl radical or a C 3 -C 6 heterocyclic radical which can be optionally substituted by one or more C 1 -C 6 alkyl, aryl, heteroaryl or halogen radicals and d) a radical selected from the group consisting of linear or branched C 1-C 6 alkyl radicals, C 2 -C 6 alkenyl radicals and C 2 -C 6 alkynyl radicals, substituted by at least one amine of the formula wherein Y and Z are as described above; and pharmaceutically acceptable salts.
