|a Besides TNF, activated T cells play a central role in the pathogenesis of inflammatory bowel diseases such as Crohn's disease. New therapies are still awaited to cure these often debilitating diseases. Natural occurring pteridines such as tetrahydrobiopterin (BH4) and neopterin have been reported to have immune modulating activities. Starting from a pteridine scaffold library, we intended to select compounds with potent in vitro inhibitory effects on T cells and to evaluate in vivo efficacy of selected compounds on trinitrobenzenesulphonate (TNBS) colitis in mice. Compound 4AZA1378 was selected because it potently inhibits human T cell proliferation at low nM concentrations (IC50 4 nM) while an almost 50-fold higher concentration was needed to inhibit LPS-induced TNF production. Mice treated with 4AZA1378 had less severe signs of colitis after TNBS rectal administration, with a more rapid weight recovery. Myeloperoxidase (MPO) activity and intralesional cytokine production were lower in mice of the treated groups. Furthermore anti-TNBS antibody responses were completely inhibited by treatment with 4AZA1378. In conclusion, we identified a pteridine analogue 4AZA1378 with immunosuppressive activity and a strong remission-inducing effect in TNBS colitis, supporting further pre-clinical and clinical development of this novel molecule for treatment of inflammatory diseases
