Takinib

Takinib (EDHS-206) is an orally active and selective TAK1 inhibitor (IC50=9.5 nM), more than 1.5 log more potent than the second and third ranked targets, IRAK4 (120 nM) and IRAK1 (390 nM), respectively. Takinib is an inhibitor of autophosphorylated TAK1 that non-competitively binds within the ATP binding pocket. Takinib induces apoptosis following TNFα stimulation in cell models of rheumatoid arthritis and metastatic breast cancer. Takinib is also a P. falciparum protein kinase 9 (PfPK9) inhibitor (KD(app) of 0.46 μM)[1][2][3].
