Compounds or their salts of general formula (I): A-B-N(O)<SUB>s </SUB>wherein: s is an integer equal to 1 or 2; A=R-T<SUB>1</SUB>-, wherein R is the drug radical and T<SUB>1</SUB>=(CO)<SUB>t </SUB>or (X)<SUB>t'</SUB>, wherein X=O, S, NR<SUB>1c</SUB>, R<SUB>1c </SUB>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=-T<SUB>B</SUB>-X<SUB>2</SUB>-O- wherein T<SUB>B</SUB>=(CO) when t=0, T<SUB>B</SUB>=X when t'=0, X being as above defined; X<SUB>2 </SUB>is equal to R<SUB>1B-X-R</SUB><SUB>2B </SUB>radical wherein X is as above defined, R<SUB>1B </SUB>and R<SUB>2B</SUB>, equal to or different from each other, are linear or branched C<SUB>1</SUB>-C<SUB>6 </SUB>alkylenes, or X<SUB>2 </SUB>is a radical wherein two alkylene chains C<SUB>1</SUB>-C<SUB>4 </SUB>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.
