Primary TargetRIPK2

Cell permeable: yes

General description

A cell permeable, pyrazolopyridine containing macrocycle derivative that acts as a highly potent, selective, ATP-competitive and reversible inhibitor of receptor-interacting protein 2 (RIPK2, IC₅₀ = 5.3 nM). Shown to minimally affect the activity of 366 other protein kinases. At higher concentrations (100 nM), inhibits ALK-2, salt-inducible kinase 2 (SIK2), activin receptor type-2B (ACVR2B), and activin A receptor type II-like 1 (ACVRL1) by ~80%. Blocks RIPK2 autophosphorylation and downstream NF-κB and MAP kinase signaling induced by muramyl dipeptide (MDP), and reduces MDP-induced cellular infiltration of neutrophils and lymphocytes in an in vivo peritonitis model (6.25 mg/kg, i.p.).Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.

A cell permeable, highly potent, selective, and ATP-competitive inhibitor of receptor-interacting protein 2 (RIPK2, IC₅₀ = 5.3 nM).

A cell permeable, pyrazolopyrinide containing macrocycle derivative that acts as a highly potent, selective, and ATP-competitive inhibitor of receptor-interacting protein 2 (RIPK2, IC₅₀ = 5.3 nM). At ~20-fold higher concentration inhibits (~80% inhibition at 100 nM) the activity of ALK-2, salt-inducible kinase 2 (SIK2), activin receptor type-2B (ACVR2B), and activin A receptor type II-like 1(ACVRL1), but does not affect the activity of 366 other protein kinases. Blocks RIPK2 autophosphorylation and downstream NF-κB and MAP kinase signaling induced by muramyl dipeptide (MDP) and reduces MDP-induced cellular infiltration of neutrophils and lymphocytes in an in vivo peritonitis model (6.25 mg/kg).
