4-メチルピラゾール

用途有機合成原料。

説明Fomepizole is the first drug indicated as an antidote for ethylene glycol poisoning (it has also shown promise as a treatment for methanol poisoning). Fomepizole is 4-methyl-1H-pyrazole active as a synthetic alcohol dehydrogenase inhibitor, blocking the formation of toxic ethylene glycol metabolites which are responsible for a severe metabolic acidosis and renal failure. In limited human studies, it reversed the toxicity of potentially lethal doses of ethylene glycol. The main urinary metabolite has been reported to be 4-carboxypyrazole by oxidation of the methyl group. Compared with the current treatment (ethanol), the duration of action is longer and the safety is improved, with no toxic effects reported.

使用Fomepizole (4-Methylpyrazole) can be used as: A reactant to prepare 4-methyl-1-phenyl-1H-pyrazole by reacting with bromobenzene via N-arylation using a copper catalyst. A starting material for the synthesis of 4-methyl-3(5)-nitropyrazole by nitration. A ligand in the preparation of gallium(III) complex of 4-methylpyrazole as potential antitumor and antiviral agent.

一般的な説明4-Methylpyrazole inhibits CYP2E1 activity. It also acts as alcohol dehydrogenase inhibitor.
