General description

DL-buthionine-SR-sulfoximine (BSO) is an amino acid analogue, which acts as an inhibitor of γ-glutamylcysteine synthetase. BSO increases the sensitivity of Trypanosoma cruzi to antiparasitic drugs, such as nifurtimox or benznidazole.

Application

DL-Buthionine-(S,R)-sulfoximine has also been used:
  • to induce oxidative stress in Starlings
  • to deplete choroidal glutathione (GSH) in two-day-old rat pups
  • to test its inhibitory effect on the enzymes, γ-glutamylcysteine synthetase and trypanothione synthetase (TryS) from T. cruzi

DL-Buthionine-(S,R)-sulfoximine has been used to deplete cellular glutathione levels in retinal ganglion cell 5 (RGC-5) cell line.

Biochem/physiol Actions

Depletes cellular glutathione and downregulates GST level.

A common process associated with oxidative stress and severe mitochondrial impairment is the opening of the mitochondrial permeability transition pore, as described in many neurodegenerative diseases. Thus, inhibition of mitochondrial permeability transition pore opening represents a potential target for inhibiting
