| Hazard Information | Back Directory | [Uses]
4-Methylpyrazole hydrochloride has been used:
- as a cytochrome P450 2E1 inhibitor
- as cytochrome P450 2E1 and alcohol dehydrogenase inhibitor in 1C11 neural progenitor cells
- to inhibit ethanol oxidation in VL-17A cells expressing alcohol dehydrogenase and HepG2 cells
| [Biochem/physiol Actions]
4-Methylpyrazole (4MP) inhibits ethanol oxidation in liver microsomes. It also blocks the c-Jun N-terminal kinase (JNK) activation in in vitro liver injury models. | [in vivo]
Pretreatment with Fomepizole (4-Methylpyrazole; 25 mg/kg; IP) prolongs ethanol neurobehavioral toxicity in CD-1 mice[4] | Animal Model: | Male CD-1 mice weighing 18-25 g[4] | | Dosage: | 25 mg/kg | | Administration: | IP; single dose | | Result: | Decreased the dose of ethanol (1-5 g/kg; IP) at which 50% of the animals failed a particular outcome test (toxic dose 50; TD50). |
