ASK1-IN-2 是一种有效的,具有口服活性的凋亡信号调节激酶 1 (ASK1) 抑制剂,IC50值为 32.8 nM。ASK1-IN-2 可用于溃疡性结肠炎的研究。
生物活性 | ASK1-IN-2 is a potent and orally active inhibitor ofapoptosissignal-regulating kinase 1 (ASK1), with anIC50of 32.8 nM. ASK1-IN-2 can be used for the research of ulcerative colitis[1]. |
IC50& Target[1] | |
体外研究 (In Vitro) | 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].
|
体内研究 (In Vivo) | 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 hong/mL), 62.2% oral bioavailability and acceptable terminal half-life (T1/2=2.31 h) in rats[1].
Animal Model: | Male ICR mice (18-22 g, 6-8 weeks) were given 3% DSS (w/v) orally in drinking water[1] | Dosage: | 25 mg/kg | Administration: | P.o. daily for 7 days | Result: | Induced a significant recovery of body weight loss, with an increase of +11.2%. Decreased the disease activity index (DAI) score about a 2 unit. Significantly prevented colon shortening. Attenuated a severe colonic tissue damage and infiltration of inflammatory cells. |
Animal Model: | Male SD rats[1] | Dosage: | 1 mg/kg for i.v.; 10 mg/kg for p.o. (Pharmacokinetic Analysis) | Administration: | I.v. and p.o. administration | Result: | I.v.: CL=1.38 L/h/kg; T1/2=1.45 h. P.o.: AUClast=4517 hong/mL; F=62.2%; T1/2=2.31 h. |
