4-METHYLPYRAZOLE HYDROCHLORIDE

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

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.
