Nitric oxide donating carnosine compounds

A carnosine analogue of formula (I) or a pharmaceutically acceptable salt or stereoisomer thereof:

• wherein R is:
• —(Y)—(CH2)n—[CH(ONO2)]p—CH2—ONO2 1)
• —(Y)—(CH2)n—X—(CH2)n1—[CH(ONO2)]p—CH2—ONO2 2)
• wherein:
• Y is O, NH or a covalent single bond;
• n is an integer from 1 to 10, preferably 1 to 4;
• with the proviso that in formula 2) when Y is O or NH, then n is not 1;
• n1 is an integer from 1 to 10, preferably 1 to 4;
• p is 0 or 1;
• X is O, NH or S;
• R1 is OH, —OR2, −NH2, —NHR2, wherein R2 is (C1-C10) linear or branched alkyl.
