Abstract

Mucosal biofilm-related fungal infections are very common, and the incidence of recurrent oral and vulvovaginal candidiasis is significant. As resistance to azoles (the preferred treatment) is occurring, we aimed at identifying compounds that increase the activity of miconazole against Candida albicans biofilms. We screened 1,600 compounds of a drug-repositioning library in combination with a subinhibitory concentration of miconazole. Synergy between the best identified potentiators and miconazole was characterized by checkerboard analyses and fractional inhibitory concentration indices. Hexachlorophene, pyrvinium pamoate, and artesunate act synergistically with miconazole in affecting C. albicans biofilms. Synergy was most pronounced for artesunate and structural homologues thereof. No synergistic effect could be observed between artesunate and fluconazole, caspofungin, or amphotericin B. Our data reveal enhancement of the antibiofilm activity of miconazole by artesunate, pointing to potential combination therapy consisting of miconazole and artesunate to treat C. albicans biofilm-related infections.

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

  • The primary screen identified several drugs with known fluconazole chemosensitizing activities, including simvastatin, atorvastatin, lovastatin, artemisinin, amiodarone, sulfamethoxazole, doxycycline, nisoldipine, and tamoxifen.

    “In addition and as expected, the primary screen identified several drugs with known fluconazole chemosensitizing activities, such as the cholesterol-lowering agents; simvastatin, atorvastatin, and lovastatin, artemisinin, amiodarone, sulfamethoxazole, doxycycline, and the calcineurin inhibitors nisoldipine and tamoxifen19–25.”
  • The Thevissen group identified artemisinins as new potentiators of miconazole activity against C. albicans biofilms.

    “Likewise, the Thevissen group identified artemisinins as new potentiators of miconazole activity against C. albicans biofilms [56].”

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.
