The Several Activities of 4 - Methyl Pyrazole in Animals and Humans.

4-MP is a potent competitive inhibitor of ADH activity with an affinity about a 1000 times more than toxic alcohols. 4-MP was shown to reduce the formation of toxic metabolites in lethal methanol and ethylene glycol poisoning in animal models and in methanol poisoning in humans. 4-MP has long-lasting gastroprotective effect against ethanol and other chemically induced acute gastric mucosa lesions in rats. We showed, for the first time, that 4-MP also provides significant protection of the human stomach against alcohol induced acute mucosal injury.
