ASK1-IN-2 is a potent and orally active inhibitor of apoptosis signal-regulating kinase 1 (ASK1), with an IC50 of 32.8 nM. ASK1-IN-2 can be used for the research of ulcerative colitis[1].
ASK1-IN-2 (compound 19) (10 mM; 1 h) inhibits the luciferase reporter activity in AP1-HEK293 cells, with inhibition rate of 95.59%[1].
ASK1-IN-2 (25 mg/kg; p.o. daily for 7 d) improves dextran sulphate sodium (DSS)-induced ulcerative colitis (UC) in mice[1].
ASK1-IN-2 (25 mg/kg; p.o. daily for 7 d) blocks ASK1-p38/JNK signaling pathways and reduces inflammatory cytokine levels in DSS-induced mouse colon tissues[1].
ASK1-IN-2 (1 mg/kg; i.v.) shows low clearance (CL=1.38 L/h/kg) and moderate half-life (T1/2=1.45 h) in rats[1].
ASK1-IN-2 (10 mg/kg; p.o.) shows high oral exposure (AUClast=4517 h•ng/mL), 62.2% oral bioavailability and acceptable terminal half-life (T1/2=2.31 h) in rats[1].
