2-Naphthalenemethanol participates in metabolic activation of 2-methylnaphthalene
Abstract:
2-Methylnaphthalene (2-MN) is an environmental pollutant. Studies have shown that 2-MN is teratogenic, carcinogenic, and cytotoxic. However, the mechanisms of 2-MN induced toxicities remain unclear.This study aimed to characterise reactive metabolites of 2-MN, to define the metabolic pathway, and to determine the enzymes participating in the metabolic activation.A hydroxylation metabolite of 2-MN, 2-naphthalenemethanol (2-NM), was observed in 2-MN-containing mouse liver microsomes.A glutathione (GSH) conjugate was detected in mouse S9 incubations fortified with 2-MN and GSH. A GSH conjugate and an NAC conjugate were found in mouse liver and urine, respectively, in animals given 2-MN. Hepatic protein covalent binding derived from 2-NM was observed in animals administered 2-MN.Cytochrome P450 enzymes and sulfotransferases participated in the metabolic activation of 2-MN.

Phase II Reactions: Methylation Reactions
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
