Abstract des Autors
The metabolic profile of synthetic cannabinoids from different chemical classes was characterized by means of in vitro approaches with human liver microsomes (HLM) and/or of cytochrome P450s (CYPs) and glucuronosyltarnsferase (UGT) isoforms. Results showed that for all investigated synthetic cannabinoids (SCs), regardless of the chemical class, mono-hydroxylation is the most important biotransformation pathway, followed by di-hydroxylation and, to a lesser extent, by dehydrogenation; instead, other metabolic reactions observed (i.e. dealkylation, dihydrodiol formation) appeared to be strictly dependent on the chemical nature of the specific substrate. Concerning the isoenzymes mainly involved in the phase I reactions, CYP3A4, CYP2D6 and CYP2C19 are the most accountable for mono-hydroxylation, di-hydroxylation and dihydrodiol formation abundant products, while CYP3A5 and CYP1A2 are the most involved in N-dealkylation and carbonyl formation. As for phase II metabolism, glucuronidation reactions for investigated substrates are mainly catalyzed by UGT2B7, UGT2B4, UGT1A3 and UGT1A10 isoforms.
