Abstract

Buthionine sulfoximine (S-n-butyl homocysteine sulfoximine), the most potent of a series of analogs of methionine sulfoximine thus far studied (Griffith, O.W., Anderson, M.E., and Meister, A. (1979) J. Biol. Chem. 254, 1205-1210), inhibited gamma-glutamylcysteine synthetase about 20 times more effectively than did prothionine sulfoximine and at least 100 times more effectively than methionine sulfoximine. The findings support the conclusion that the S-alkyl moiety of the sulfoximine binds at the enzyme site that normally binds the acceptor amino acid. Thus, the affinity of the enzyme for the S-ethyl, S-n-propyl, and S-n-butyl sulfoximines increases in a manner which is parallel to those of the corresponding isosteric acceptor amino acid substrates, i.e. glycine, alanine, and alpha-aminobutyrate. Buthionine sulfoximine did not inhibit glutamine synthetase detectably, nor did it produce convulsions when injected into mice. Injection of buthionine sulfoximine into mice decreased the level of glutathione in the kidney to a greater extent (less than 20% of the control level) than found previously after giving prothionine sulfoximine. alpha-Methyl buthionine sulfoximine was also prepared and found to be almost as effective as buthionine sulfoximine; this compound would not be expected to undergo substantial degradative metabolism. Buthionine sulfoximine and alpha-methyl buthionine sulfoximine may be useful agents for inhibition of glutathione synthesis in various experimental systems.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Eprenetapopt may trigger an increase in turnover of GSH rather than restraining de novo GSH synthesis, unlike erastin or l-buthionine sulfoximine.

    “eprenetapopt may be unique, triggering an increase in turnover of GSH rather than restraining de novo GSH synthesis, as imposed by erastin through its inhibition of cystine uptake or by l-buthionine sulfoximine through inhibition of glutamate-cysteine ligase (40).”
  • Buthionine sulfoximine (BSO), an inhibitor of glutamate cysteine ligase (GCL), depletes GSH and exhibits anticancer activity.

    “buthionine sulfoximine (BSO), an inhibitor of glutamate cysteine ligase (GCL), the enzyme required for GSH synthesis, depletes GSH and exhibits anticancer activity”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
