Figure 5From: Ozagrel hydrochloride, a selective thromboxane A2 synthase inhibitor, alleviates liver injury induced by acetaminophen overdose in mice Effects of ozagrel on hepatic GSH depletion induced by APAP and CYP 2E1 level. (A) Mice were treated with ozagrel (200 mg/kg), NAC (600 mg/kg) or saline 30 min after the APAP (330 mg/kg) injection. The liver tissue samples were collected 0, 2 and 4 h after the APAP injection. Significant decreases in hepatic total GSH level were observed in all groups. The GSH level of APAP + NAC group was significantly higher than that of APAP group and APAP + ozagrel group at 2 h. Each value represents the mean ± S.E.M. (n = 4–5). *p < 0.001 compared with the 0 h group. # p < 0.001 compared with the APAP group and APAP + ozagrel group. (B) CYP 2E1 level in mouse hepatic microsomes was evaluated using a fluorogenic probe, the Vivid® CYP2E1 Blue Substrate. Ozagrel at various concentrations (0.001–1.0 mg/mL) was incubated with the reaction mixture and the fluorescence intensity of the fluorescent metabolite was measured. Each value represents the mean ± S.E.M. (n=3). There were no significant differences between the groups.Back to article page
