Sulphated disaccharides for the treatment of neurodegenerative and/or neurovascular diseases

A method for the treatment of an oxidation-associated neurodegenerative and/or neurovascular disease, comprising administering to a mammal in need thereof an effective amount of a compound of formula (I)

• wherein:
• R1 is selected from hydrogen, linear or branched C1-C4 alkyl, phenylalkyl of less than ten carbon atoms and —COCH3;
• R2 is selected from hydrogen, —COCH3 and —SO3Y;
• R3 is selected from hydrogen, linear or branched C1-C4 alkyl, phenylalkyl of less than ten carbon atoms, —COCH3 and —COPh, wherein Ph is phenyl;
• G is selected from —COOR4 and —COOY;
• one of A or B is selected from hydrogen, —SO3H, —SO3Y and —COCH3, and the other
• A or B is —SO3H or —SO3Y;
• R4 is selected from hydrogen, C1-C2 alkyl and arylalkyl of less than sixteen carbon atoms,
• Y is an organic or inorganic cation;
• or a pharmaceutically acceptable salt thereof;
• wherein the oxidation-associated neurodegenerative and/or neurovascular disease is selected from the group consisting of Alzheimer's Disease, Parkinson's Disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, transient ischemic brain attack, Huntington's disease, Friedreich's ataxia, spongiform encephalopathies, dementia with Lewy bodies, Pick's disease, mild cognitive impairment, epilepsy, migraine, schizophrenia, bipolar disorder, vascular dementia and cerebrovascular arteriosclerosis.
