ABSTRACT:
Compositions are provided comprising chito-oligomers obtainable from chitin, comprising oligomers of N-acetyl glucosamine (NAG) and glucosamine, wherein at least 50% of the oligomers have a chain length of about 2-50, and the degree of deacetylation of the oligomers is in the range of about 0-70%, preferably about 30-50%. The compositions are highly useful as pharmaceutical compositions for treatment of joint disorders such as rheumatoid arthritis and osteoarthritis. Also provided are methods for treatment of joint disorders and treatment against inflammatory activity.
