Background:

NO-prednisolone is a nitric oxide (NO)-releasing derivative of Prednisolone. NO-prednisolone potently stimulates IL-10 production in vivo. IL-10[1]


NO-prednisolone (NCX-1015), an NO-releasing derivative of Prednisolone, is demonstrated to be more effective than Prednisolone in reducing inflammation, inhibiting cytokine and chemokine generation, and up-regulating the expression of the steroid-sensitive cell-surface marker CD163 in human peripheral blood mononuclear cells[1] Incubation of PBMCs with NO-prednisolone (NCX-1015) and Prednisolone produces a concentration-dependent activation of CD163. NO-prednisolone is more potent than Prednisolone at inducing CD163 cell surface expression. The increased efficacy of NO-prednisolone, compared with the parent molecule Prednisolone, is also observed when assessing inhibition of LPS induced IL-1β production[2].


In vivo treatment with NO-prednisolone (NCX-1015) potently stimulates IL-10 production, suggesting that the NO steroid induces a regulatory subset of T cells that negatively modulates intestinal inflammation. The two doses of NO-prednisolone tested, 0.5 and 5 mg/kg/day (equivalent to 0.33 and 3.3 mg/kg/day prednisone, respectively) effectively attenuates the severity of the wasting syndrome, ameliorates the colitis score, and reduces the colonic myeloperoxidase (MPO) activity. NO-prednisolone administration also reduces the colonic mRNA and protein content of tumor necrosis factor-α, IL-12, and IFN-γ. NO-prednisolone also reduces the expression of inducible NO synthase and cyclooxygenase-2 but in contrast does not inhibit colonic expression of IL-10 mRNA or protein. In fact, IL-10 expression is enhanced in mice treated with NO-prednisolone[1].
