SP600125

Selective inhibitor of c-Jun N-terminal kinase (JNK). Competitively and reversibly inhibits JNK1, 2 and 3 (IC50 = 40 - 90 nM) with negligible activity at ERK2, p38β and a range of enzymes (IC50 > 10 µM). Active in vivo. Shown to have reduced selectivity over other protein kinases under certain conditions. Protects renal tubular epithelial cells against ischemia/reperfusion-induced apoptosis.
