    Abstract: Tryptophan metabolism has been recognized as an important mechanism in immune tolerance. Indoleamine 2,3-dioxygenase plays a key role in local tryptophan metabolism via the kynurenine pathway and has emerged as a therapeutic target for cancer immunotherapy. Our prior study identified phenyl benzenesulfonyl hydrazide 2 as a potent in vitro (though not in vivo) inhibitor of indoleamine 2,3-dioxygenase. Further lead optimization to improve in vitro potencies and pharmacokinetic profiles resulted in N'-(4-bromophenyl)-2-oxo-2,3-dihydro-1H-indole-5-sulfonyl hydrazide 40, which demonstrated 59% oral bioavailability and 73% of tumor growth delay without apparent body weight loss in the murine CT26 syngeneic model, after oral administration of 400 mg/kg. Accordingly, 40, is proposed as a potential drug lead worthy of advanced preclinical evaluation.
