Abstract
The effects of six Thai fruits, namely banana, guava, mangosteen, pineapple, ripe mango and ripe papaya, on cytochrome P450 (P450) activities were investigated. The median inhibitory concentrations (IC50) of each of the fruit juices on CYP1A1, CYP1A2, CYP2E1 and CYP3A11 activities were determined. Pineapple juice showed the strongest inhibitory effect against all the evaluated P450 isozyme activities in mouse hepatic microsomes, followed by mangosteen, guava, ripe mango, ripe papaya and banana. The study was further performed in male ICR mice given pineapple juice intragastrically at doses of 10, 20 and 40 mg kg−1 per day for 7 or 28 days. In a concentration‐dependent fashion, the pineapple juice raised ethoxyresorufin O‐deethylase, aniline hydroxylase and erythromycin N‐demethylase activities, which are marker enzymatic reactions responsible for CYP1A1, CYP2E1 and CYP3A11, respectively. The effect of pineapple juice on the expression of CYP1A1, CYP2E1 and CYP3A11 mRNAs corresponded to their enzymatic activities. However, the pineapple juice significantly decreased methoxyresorufin O‐demethylase activity. These observations supported that the six Thai fruits were a feasible cause of food–drug interaction or adverse drug effects owing to their potential to modify several essential P450 activities. Individuals consuming large quantities of pineapple for long periods of time should be cautioned of these potential adverse effects. Copyright © 2012 John Wiley & Sons, Ltd.
