Compounds or their salts of general formula (I): A-B-N(O)s wherein: s is an integer equal to 1 or 2; A=R-T1-, wherein R is the drug radical and T1=(CO)t or (X)t′, wherein X=O, S, NR1c, R1c is H or a linear or branched alkyl or a free valence, t and t′ are integers and equal to zero or 1, with the proviso that t=1 when t′=0; t=0 when t′=1; B=-TB-X2—O— wherein TB=(CO) when t=0, TB=X when t′=0, X being as above defined; X2 is equal to R1B-X-R2B radical wherein X is as above defined, R1B and R2B, equal to or different from each other, are linear or branched C1-C6 alkylenes, or X2 is a radical wherein two alkylene chains C1-C4 are linked to nonadjacent positions of a central ring having 4 or 6 atoms, said ring being an unsaturated cycloaliphatic ring, or a saturated or aromatic heterocylic ring, containing one or two heteroatoms, equal or different, selected from O, S, N; wherein the unsaturated cycloaliphatic ring does not have aromatic character according to Huckel's rule.
