PROTAC IDO1 Degrader-1 is the first potent IDO1 (indoleamine 2,3-dioxygenase 1) degrader that hijacks IDO1 to CRBN E3 ligase to introduce IDO1 into UPS and eventually achieve ubiquitination and degradation (DC50=2.84 μM). PROTAC IDO1 Degrader-1 moderately improves the tumor-killing activity of H ER2 CAR-T cells[1]. PROTAC IDO1 Degrader-1 (compound 2c) (10 μM; 24 hours) notably decreases IDO1 level induced by IFN-γ[1].PROTAC IDO1 Degrader-1 and IFN-γ (5 ng mL) are incubated with HeLa cells for 24 h, and a significant dose-dependent degradation is observed. PROTAC IDO1 Degrader-1 combined with chimeric antigen receptor-modified T (CAR-T) cells can improve the tumor-killing activity of HER-2 CAR-T cells[1].PROTAC IDO1 Degrader-1 induces significant and persistent degradation of IDO1 with maximum degradation (dmax) of 93% in HeLa cells[1].

Benpyrine is a highly specific and orally active TNF-α inhibitor with a KD value of 82.1 μM. Benpyrine tightly binds to TNF-α and blocks its interaction with TNFR1, with an IC50 value of 0.109 μM. Benpyrine has the potential for TNF-α mediated inflammatory and autoimmune disease research[1]. Benpyrine (5-20 μM; 14 hours; RAW264.7 cells) pretreatment results in a dose-dependent decrease in the phosphorylation of IκBα in RAW264.7 cells (stimulated with 10 ng mL TNF-α or 1 μg mL LPS). Benpyrine abolishes the TNF-α-induced nuclear translocation of NF-κB p65 in RAW264.7 cells[1].Benpyrine only blocks cell death induced by TNF-αWT and Y119A, and increases the cell survival rate up to 80%. Benpyrine does not obviously affect L57A- and Y59L-induced cytotoxicity in L929 cells[1]. Benpyrine (25-50 mg kg; oral gavage; daily; for 2 weeks; Balb c mice) treatment significantly relieves the symptoms of collagen-induced arthritis. Benpyrine dose-dependently decreases the levels of proinflammatory cytokines, such as IFN-γ, IL-1β and IL-6, and increases the concentration of the anti-inflammatory cytokine IL-10[1].Endotoxemia murine model shows that Benpyrine (25 mg kg) could attenuate TNF-α-induced inflammation, thereby reducing liver and lung injury[1].
