Nitric oxide (NO)-releasing non-steroidal anti-inflammatory drugs (NSAIDs) have been reported to have a safer profile and additional anti-inflammatory and immuno-modulatory properties compared to parent compounds.

Preventive treatment of experimental autoimmune encephalomyelitis (EAE)-induced in C57BL/6 mice by immunization with myelin oligodendrocyte glycoprotein (MOG) peptide 35-55-with the NO-releasing derivative of flurbiprofen HCT1026 delayed disease onset and significantly decreased disease severity.

HCT1026 treatment was associated to

(i) decreased mRNA levels of pro-inflammatory cytokines, caspase-1, and iNOS in blood cells;

(ii) decreased ability of encephalitogenic T cells to proliferate;

(iii) reduced number of central nervous system (CNS)-infiltrating T cells;

(iv) decreased axonal loss and demyelination; (v) increased CD4(+) CD69(-) CD25(+) regulatory T cells in the spleen.
