| Bioactivity | RN486 is a potent, selective and orally active Btk inhibitor with an IC50 of 4.0 nM and a Kd of 0.31 nM. RN486 is less active for other kinases. RN486 can be used for rheumatoid arthritis and systemic lupus erythematosus research[1][2][3]. | ||||||||||||
| Target | IC50: 4.0 nM (Btk)Kd: 0.31 nM (Btk) | ||||||||||||
| Invitro | RN486 blocks Fcε receptor cross-linking-induced degranulation in mast cells (IC50 = 2.9 nM), Fcγ receptor engagement-mediated tumor necrosis factor α production in monocytes (IC50 = 7 nM), and B cell antigen receptor-induced expression of an activation marker, CD69, in B cells in whole blood (IC50 = 21 nM)[1].In a co-culture system consisting of human primary synovial FLS and activated human platelets, convulxin stimulation resulted in elevated production of pro-inflammatory cytokines, IL-6 and IL-8, an effect which is dose-dependently blocked by RN486[2]. | ||||||||||||
| In Vivo | RN486 produces robust anti-inflammatory and bone-protective effects in mouse CIA and rat adjuvant-induced arthritis (AIA) models. In the AIA model, RN486 (1-30 mg/kg) inhibits both joint and systemic inflammation, reducing both paw swelling and inflammatory markers in the blood[1]. | ||||||||||||
