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.

Buthionine sulfoximine (BSO) induces decreased glutathione (GSH) and trypanothione [T(SH)2 ] pools in trypanosomatids, presumably because only gamma-glutamylcysteine synthetase (γECS) is blocked. However, some BSO effects cannot be explained by exclusive γECS inhibition; therefore, its effect on the T(SH)2 metabolism
