“The plant polyphenols namely tannic acid, butein, quercetin, morin, 2-hydroxychalcone and 2'-hydroxychalcone at 40 microM inhibited the GST-mediated conjugation of CMB with GSH by 38 to 62%.”
“Unexpectedly, we found in our study that both the spontaneous and the enzymatic conjugation of chlorambucil with GSH were affected markedly by a change in pH from 6.0 to 8.0.”
