I want to perform an inhibition study of GR in fish primary hepatocytes. Is there any Glutathione reductase specific inhibitor which can inhibit only GR not other disulfide oxidoreductase? Thanks in advance.
There are specific inhibitors such as S-nitrosoglutathione and 2-acetylamino-3- [4- (2-acetylamino-2-carboxyethylsulfanylthio carbonylamino) phenylthiocarbamoylsulfanyl] propionic Acid (2-AAPA). Annex specific references.
Every molecule that reacts with free SH groups inhibits GR int that this enzyme bears two SH in the active site. Thus is easy to inhibit its activity but difficult to do it specifically.
To best of my knowledge the best inhibitor is BCNU (carmustine), I have used it and it is very efficient.
