WebApr 10, 2024 · One reason for this is the lack of a proper method to evaluate the risk posed by acyl-CoA conjugates. There are some reports describing that GSH captures acyl-CoA conjugates in trapping assays and forms thioester adducts detectable by LC/MS analysis [16]. However, the adducts containing a thioester are easily hydrolyzed to parent drugs. WebMay 18, 2000 · DOI: 10.1016/s0047-6374 (00)00105-6 Abstract Aflatoxin B1 (AFB1)-glutathione (GSH) conjugation is the major pathway for the detoxification of aflatoxin metabolites. This reaction is catalysed by GSH S-transferase (GST) and play a major role in modulation of AFB1 adduct formation to nuclear DNA.
