BMS-986242 is an orally active, potent and selective indoleamine-2,3-dioxygenase 1 (IDO1) inhibitor. BMS-986242 can be used for the research of cancer[1]. BMS-986242 is more prone to oxidative metabolism and less susceptible to glucuronidation. BMS-986242 shows IC50>25 μM for all targets except nAChR a1 (IC50=12.3 μM) and nAChR a7 (IC50>6 μM with ～20 % max inhibition)[1]. BMS-986242 (3~30 mg/kg; p.o.; 0~24 hours) exhibits dose-proportional exposure and a statistically significant reduction in kynurenine concentration in the tumor at all three doses[1].
