    THE INFLUENCE OF METHANANDAMIDE AND SEX ON THE ACTIVITY OF CYTOCHROME P 450 AS A PREDICTIVE FACTOR OF XENOBIOTICS TOXICITY

  • Original language description

    The primary active constituent of the hemp plant Cannabis sativa is 9-tetrahydrocannabinol (THC)1. Anandamide, an endogenous ligand for brain cannabinoid CB1 receptor, produces many behavioural effects similar to those of THC. (R)-(+)-methanandamide (MET) is a synthetic long-lasting arachidonylethanolamide (anandamide) analogue. The enzymatic system of cytochrome P450 (CYP450) is part of phase I of enzymatic biotransformation. Interindividual variability of activity of oxidative and conjugating enzymes,especially the system of CYP450, can be based on many exogenous as well as endogenous influences e.g. sex, age or genetic factors. The aim of this work was to investigate the effect of repeated administration of (MET) on rat liver CYP2D2 isoenzyme usingdextromethorphan (DEM) as a specific marker4. We have also studied the role of sex on the activity of CYP2D2 isoenzyme. The activity of CYP2D2 differed due to pretreatment with methanandamide. In our experiments the influence of this com

    VPLYV METANANDAMIDU NA AKTIVITU CYTOCHRÓMU P450 AKO PREDIKČNÉHO FAKTORU TOXICITY XENOBIOTÍK V ZÁVISTLOSTI OD POHLAVIA

  • Czech description

    Endogénny kanabinoidný systém a možnosti ovplyvnenia jeho funkcií sú v súčasnej dobe intenzívne študované v súvislosti s možným použitím v rôznych patologických stavoch a hlavne v psychiatrických indikáciách. Metanadamid je syntetický agonista CB1 receptorov, ktoré sú lokalizované hlavne v mozgu. Významná časť liečiv zo skupiny psychofarmák je metabolizovaná enzymatickým systémom cytochrómu P 450 (CYP450) v pečeni. Medzi faktory ovplyvňujúce aktivitu CYP450 patrí napr. vek, pohlavie alebo patofyziologický stav. Cieľom práce je zistiť vplyv metanandamidu na aktivitu pečeňovej izoformy CYP2D2 v závislosti na pohlaví na modeli izolovanej perfundovanej pečene u potkanov kmeňa Wistar. Ako selektívny marker pečeňovej izoformy CYP2D2 sme použili dextrometorfan (DEM), ktorý je metabolizovaný na špecifický metabolit dextrorfan (DOR). Koncentrácia DEM v perfúznom médiu (Williamsov roztok E) bola 1.2 mg/120ml. Metanandamid bol podávaný v dávke 1 mg/kg i.p. po dobu 7 dní. Vzorky perfuzátu pre bioc
