Repurposing Thiram and Disulfiram as Antibacterial Agents for Multidrug-Resistant Staphylococcus aureus Infections

Open access
Long, Timothy E.·2017·Antimicrobial Agents and Chemotherapy

Abstract

Thiram and disulfiram were evaluated as antibacterial agents against multidrug-resistant Staphylococcus aureus . Against a 30-member panel comprised of vancomycin-susceptible, vancomycin-intermediate, and vancomycin-resistant S. aureus strains, the MIC 90 values of the respective test agents were 4 and 16 μg/ml. Additional analyses revealed that thiram and disulfiram are rapid-acting bacteriostatic agents with narrow, Gram-positive-bacterium spectrum activity. Synergy studies further determined that disulfiram increases the vancomycin susceptibility of three clinical vancomycin-resistant S. aureus strains in vitro , thus establishing a potential use in combination therapy.

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?

  • DIS, an electrophilic compound, readily forms disulfides with thiol-bearing molecules; bacteria harbor diverse intracellular thiols that DIS can modify via thiol-disulfide exchange, triggering antimicrobial effects.

    “DIS, an electrophilic compound, readily forms disulfides with thiol-bearing molecules. Bacteria harbor diverse intracellular thiols, including cofactors (e.g., coenzyme A), metabolites (e.g., glutathione, mycothiol, and bacillithiol), and enzymes (e.g., thioredoxin), that DIS can modify via thiol-disulfide exchange, triggering antimicrobial effects.100”
  • Exogenous glutathione raises minimal inhibitory concentrations 2-fold for DIS, explaining its limited activity against thiol-rich Gram-negatives versus Gram-positives.

  • Initial growth deceleration stems from rapid DIS cleavage by cellular thiols in proteins, metabolites, and cofactors, abruptly halting metabolism; cleavage yields mixed disulfides that undergo further thiol-disulfide exchange, producing disulfides and DDC.

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.
