产品描述:
WEHI-345 is an inhibitor of receptor-interacting protein kinase 2 (RIPK2; IC50 = 130 nM in a kinase assay using human recombinant RIPK2).{41305} It is selective for RIPK2 over RIPK1, 4, and 5 (Kds = 46, >10,000, >10,000, and >10,000 nM, respectively) and a panel of 95 kinases at a concentration of 1 μM. WEHI-345 reduces levels of RIPK2 phosphorylation at Ser176 in bone marrow-derived macrophages (BMDMs) stimulated by muramyl dipeptide (MDP). It decreases MDP-induced transcription of TNF and IL-6 in BMDMs and reduces mRNA levels of the NF-κB target genes TNF, IL-8, IL-1β, and A20 in MDP-stimulated THP-1 cells in a concentration-dependent manner. WEHI-345 (3-10 mg/kg) reduces plasma levels of TNF and delays disease onset in a mouse model of experimental autoimmune encephalomyelitis (EAE).
