Biological Activity for SP 600125

SP 600125 is a selective JNK inhibitor. Competitively and reversibly inhibits JNK1, 2 and 3 (IC₅₀ = 40 - 90 nM) with negligible activity at ERK2, p38β and a range of enzymes. Active in vivo. Exhibits reduced selectivity over other protein kinases under certain conditions. SP 600125 protects renal tubular epithelial cells from ischemia/reperfusion-induced apoptosis. Promotes chondrogenesis of bone mesenchymal stem cells by inhibition of TNF-α-induced inflammation. Adipogenesis from MSCs is also promoted by SP 600125. Essential component of medium for maintaining stem cells in naive pluripotent state.
