BC-1382 is a potent ubiquitin E3 ligase HECTD2 inhibitor that specificly disrupts the HECTD2/PIAS1 interaction (IC50≈ 5 nM).Anti-inflammatory activity[1].
BC-1382 targets HECTD2 and attenuates lipopolysaccharide (LPS)- and Pseudomonas aeruginosa-induced lung inflammation. HECTD2 is an ubiquitin E3 ligase. BC-1382 reduces the severity of cytokine-driven lung inflammation[1].
BC-1382 drastically increases PIAS1 protein level in a nonstimulus condition with IC50≈100 nM[1].
BC-1382 improves PIAS1 protein stability by increasing its t1/2[1].
BC-1382 suppresses LPS-induced PIAS1 degradation and restores PIAS1 protein levels at 800 nM[1].
BC-1382 suppresses LPS-induced proinflammatory cytokines released by human peripheral blood mononuclear cells (PBMCs)[1].
BC-1382 (10 mg/kg; intraperitoneal injection) significantly decreases lavage protein concentrations, lavage cell counts, and cell infiltrates in both PA103-stimulated and LPS-stimulated mice. BC-1382 significantly decreases lavage cytokine levels in both models[1].
| Animal Model: | C57BL/6J mice were challenged intratracheally with PA103 (104 CFU per mouse) or LPS (3 mg/kg)[1] |
| Dosage: | 10 mg/kg |
| Administration: | Given through intraperitoneal injection |
| Result: | Significantly decreased lavage protein concentrations, lavage cell counts, and cell infiltrates in both PA103-stimulated and LPS-stimulated mice. Significantly decreased lavage cytokine levels in both models. |
