Antihistaminic activity of pulegone on the guinea-pig ileum

, 1990
Pulegone, a natural monoterpene compound, has an antihistamine effect on guinea-pig ileum. Its antagonism is of the competitive type (PA2 = 6.35) like that of mepyramine and dexchlorpheniramine, two H1-antagonists, with PA2 values of 10.15 and 8.74 ...

Stereoselective hydroxylation of 4-methyl-2-cyclohexenone in rats: its relevance to R-(+)-pulegone-mediated hepatotoxicity

, 2002
R-(+)-Pulegone, a monoterpene ketone, is a potent hepatotoxin. One of the major metabolites of pulegone has been shown to be p-cresol, a glutathione depletor and a known toxin. Allylic hydroxylation of 4-methyl-2-cyclohexenone results in the formation of
