Claim:
A compound of formula (II″): wherein: R 1″ stands for hydrogen atom or a straight or branched C 1-4 alkyl; R 2″ stands for hydrogen atom or a straight or branched C 1-4 alkyl; R 3″ stands for hydrogen atom, straight or branched C 1-4 alkyl, or C 3-6 cycloalkyl, phenyl, thienyl, or furyl, each of which is optionally substituted with one or more straight or branched C 1-4 alkyl, straight or branched C 1-4 alkoxy, or halogen atom; six- or five-membered heteroaromatic ring containing one, two or three nitrogen atoms, or five-membered heteroaromatic ring containing one nitrogen atom and one oxygen atom, or one nitrogen atom and one sulphur atom, which heteroaromatic ring is optionally substituted with one or more straight or branched C 1-4 alkyl, straight or branched C 1-4 alkoxy, or halogen atom; R 4″ and R 5″ independently stand for hydrogen atom, C 3-6 cycloalkyl, straight or branched C 1-4 alkyl, each of which is optionally substituted by a hydroxy, a carboxy, straight or branched C 1-4 alkoxy, amino, or amino substituted with one or two straight or branched C 1-4 alkyl, or protective group; R 4″ stands for hydrogen atom or a straight or branched C 1-4 alkyl or a benzyl, and R 5″ stands for hydrogen atom, —SO 2 OH, straight or branched C 1-4 acyl or protective group, or R 4″ and R 5′ taken together with the nitrogen atom to which they are attached form a group of the general formula a″.) R 6″ stands for hydrogen atom or straight or branched C 1-4 alkyl, phenyl, benzyl, thienyl, or furyl, each of which is optionally substituted with methylenedioxy, or one or more straight or branched C 1-4 alkyl, straight or branched C 1-4 alkoxy, hydroxy, trifluoromethyl, cyano or halogen atom; or six- or five-membered heteroaromatic ring containing one, two or three nitrogen atoms, or one nitrogen atom and one oxygen atom, or one nitrogen atom and one sulphur atom, which heteroaromatic ring is optionally substituted with one or more straight or branched C 1-4 alkyl, straight or branched C 1-4 alkoxy or halogen atom; R 7″ and R 8″ independently stand for hydrogen atom, straight or branched C 1-4 alkyl or C 3-6 cycloalkyl; X″ stands for —CH 2 —, —NH—, —NR 9″ —, sulphur atom, oxygen atom, sulpho or sulphoxy; R 9″ stands for straight or branched C 1-4 alkyl or C 3-6 cycloalkyl; Z″ stands for oxygen atom, sulphur atom, —CHR 10″ — or —NR 11″ —; R 10″ stands for hydrogen atom, straight or branched C 1-4 alkyl, or C 3-6 cycloalkyl; R 11″ stands for hydrogen atom, straight or branched C 1-4 alkyl, C 3-6 cycloalkyl, —SO 2 OH, straight or branched C 1-4 acyl or protective group; n″ represents zero, 1 or 2; m″ represents 1, 2, or 3; o″ represents 1, 2, or 3; p″ represents zero or 1; and r″ represents zero or 1.
