General description

1-Chloro-2,4-dinitrobenzene on incubation with erythrocyte undergoes conjugation with erythrocyte glutathione (GSH) to form 2,4-dinitrophenyl-S-glutathione. It is an irreversible inhibitor of human thioredoxin reductase.

Application

1-Chloro-2,4-dinitrobenzene has been used as alkylating agent to evaluate the depletion of intracellular erythrocyte glutathione (GSH).

Erythrocyte glutathione (GSH) can be rapidly depleted by incubating the cells with 1-chloro-2,4-dinitrobenzene (CDNB), which forms 2,4-dinitrophenyl-S-glutathione with GSH through the reaction catalyzed by glutathione S-transferase. GSH-CDNB conjugate thus formed stays undegraded within the erythrocytes. This indicates that in the

Human thioredoxin reductase is a dimeric enzyme that catalyzes reduction of the disulfide in oxidized thioredoxin by a mechanism involving transfer of electrons from NADPH via FAD to a redox-active disulfide. 1-Chloro-2,4-dinitrobenzene (DNCB) is an alkylating agent used for depleting

Several in vitro DNA microarray studies have shown the importance of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) in skin sensitization. Nevertheless, the exact in vivo role of the Nrf2-Keap1 pathway during the induction of skin sensitization remains unknown. To study
