NLG919 Chemical Properties,Usage,Production

Description

(±)-NLG-919 is an indoleamine 2,3-dioxygenase (IDO) pathway inhibitor (K_i = 7 nM; EC₅₀ = 75 nM). (±)-NLG-919 inhibits IDO-induced T cell suppression and restores T cell response during allogenic mixed lymphocyte reactions in vitro (ED₅₀s = 80 and 120 nM, respectively). In vivo, (±)-NLG-919 induces a 95% reduction in tumor volume when administered in conjunction with a pmel-1 T cell vaccine. Formulations containing (±)-NLG-919 are under investigation in clinical trials for treatment of glioblastoma, melanoma, pancreatic, and breast cancers.

Uses

NLG919 is a potent indoleamine-2,3-dioxygenase (IDO) pathway inhibitor and is suitable for the treatment of immunosuppression associated with cancer.
