| | NLG919 Usage And Synthesis |
| Description | (±)-NLG-919 is an indoleamine 2,3-dioxygenase (IDO) pathway inhibitor (Ki = 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. | | Synthesis | Sodium borohydride (81 mg, 2.14 mmol) was slowly added to a methanol solution (5 mL) containing 1-cyclohexyl-2-[5H-imidazo[4,3-a]isoindol-5-yl]ethan-1-one (300 mg, 1.07 mmol) at 0 °C. The reaction mixture was stirred continuously at 0 °C for 30 min. Subsequently, the reaction was quenched with deionized water (30 mL) and extracted with ethyl acetate (50 mL x 2). The organic phases were combined, washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was removed by concentration under reduced pressure and the residue was purified by fast column chromatography using a solvent mixture of dichloromethane and methanol (1% to 6% gradient) as eluent to afford 1-cyclohexyl-2-(5H-imidazo[5,1-a]isoindol-5-yl)ethanol as a colorless oil (250 mg, 83% yield). Mass spectrometry result: m/z = 283.1 [M + H]+. | | target | IDO pathway | | References | [1] M. MAUTINO.
