BMS-986205

BMS-986205 is a selective, irreversible inhibitor of indoleamine 2,3-dioxygenase 1 (IDO1), with an IC₅₀ of 1.1μM in HEK293 cells overexpressing human IDO1^{[1, 2]}. BMS-986205 possesses immunomodulatory and antitumor activities and has entered clinical trials for various cancer types, including bladder cancer, head and neck cancer, endometrial cancer, gastric cancer, melanoma, liver cancer, non-small cell lung cancer, and solid tumors^{[3, 4]}. BMS-986205 can reverse the anti-autistic effects of Taprenepag by inhibiting IDO1^[5]. BMS-986205 can inhibit the ubiquinone reduction site of respiratory chain complex I, thereby impairing mitochondrial ATP production and interfering with glycolysis and oxidative phosphorylation (OXPHOS)^[6].

In vitro, treatment of Jurkat cells with BMS-986205 (0-100µM) for 72h induced cell death in a dose-dependent manner, with an IC₅₀ value of 6.3μM^[7].

In vivo, treatment of mice with unilateral ureteral obstruction (UUO) with BMS-986205 (10mg/kg) via intraperitoneal injection twice daily for 7 days reduced collagen deposition in the kidneys^[8].
