8-Nitrotryptanthrin is a potent human indoleamine 2,3-dioxygenase 2 (hIDO2) inhibitor which significantly reduces IDO2 activity with Ki of 0.97 μM.
The typtanthrin derivative 8-Nitrotryptanthrin (5i) is found to be a potent hIDO2 inhibitor with superior efficiency far better than that of the most frequently-used inhibitor L-1-MT. The IC50 values show that all nine tryptanthrin compounds display hIDO2 inhibitory activities, especially, the compound 8-Nitrotryptanthrin demonstrates much stronger inhibition (1.87 μM) than both L-1-MT (82.53 μM) and D-1-MT (262.75 μM). 8-Nitrotryptanthrin exhibits significant antitrypanosomal activity with EC50 of 0.82 μM[2]. 8-Nitrotryptanthrin has a microplate Alamar Blue assay (MABA) minimum inhibitory concentration (MIC) value of 0.032 μg/mL. 8-Nitrotryptanthrin also has a LORA MIC value of 2.4 μg/mL, while the majority of analogues lack LORA activity[3].
