N-acetyl glucosamine (N-ACÉTYLGLUCOSAMINE) is a natural amino sugar found in various human tissues with previously described anti-inflammatory effects. Various chemical modifications of N-ACÉTYLGLUCOSAMINE have been made to promote its biomedical applications. In this study, we synthesized two bi-deoxygenated N-ACÉTYLGLUCOSAMINE, BNAG1 and BNAG2 and investigated their anti-inflammatory properties, using an in vivo and in vitro inflammation mouse model induced by lipopolysaccharide (LPS). Among the parent molecule N-ACÉTYLGLUCOSAMINE, BNAG1 and BNAG2, BNAG1 showed the highest inhibition against serum levels of IL-6 and TNF α and the leukocyte migration to lungs and peritoneal cavity in LPS challenged mice, as well as IL-6 and TNF α production in LPS-stimulated primary peritoneal macrophages. BNAG2 displayed an anti-inflammatory effect which was comparable to N-ACÉTYLGLUCOSAMINE. These findings implied potential application of these novel N-ACÉTYLGLUCOSAMINE derivatives, especially BNAG1, in treatment of certain inflammation-related diseases.
