Antifungal agents: mechanisms of action

Odds, Frank C., Brown, Alistair J.P., Gow, Neil A.R.·2003·Trends in Microbiology

Abstract

Clinical needs for novel antifungal agents have altered steadily with the rise and fall of AIDS-related mycoses, and the change in spectrum of fatal disseminated fungal infections that has accompanied changes in therapeutic immunosuppressive therapies. The search for new molecular targets for antifungals has generated considerable research using modern genomic approaches, so far without generating new agents for clinical use. Meanwhile, six new antifungal agents have just reached, or are approaching, the clinic. Three are new triazoles, with extremely broad antifungal spectra, and three are echinocandins, which inhibit synthesis of fungal cell wall polysaccharides--a new mode of action. In addition, the sordarins represent a novel class of agents that inhibit fungal protein synthesis. This review describes the targets and mechanisms of action of all classes of antifungal agents in clinical use or with clinical potential.

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?

  • Polyenes are the oldest class of antifungal agents, dating back to the 1950s, with amphotericin B being the first FDA-approved antifungal for invasive fungal infections including candidiasis.

    “The polyenes are the oldest class of antifungal agents, their discovery and development dating back to the 1950s, with amphotericin B being the first ever FDA-approved antifungal for the treatment of invasive fungal infections, including candidiasis [23,24].”
  • The lack of highly selective targets contributes to the elevated toxicity frequently associated with antifungal therapy.

    “this lack of highly selective targets also contributes to the elevated toxicity frequently associated with antifungal therapy [23].”
  • Azoles target ergosterol by inhibiting its biosynthetic pathway, specifically cytochrome P-450 14-alpha lanosterol demethylase, and are considered fungistatic.

    “Azoles also target ergosterol, but by inhibiting its biosynthetic pathway, most specifically the cytochrome P-450 14-alpha lanosterol demethylase, and they are considered fungistatic drugs [23,25].”
  • Polyene efficacy is severely compromised by intrinsic toxicity, particularly nephrotoxicity, and infusion-related toxicity.

    “However, their efficacy is severely compromised by their intrinsic toxicity, particularly nephrotoxicity, and also by infusion-related toxicity [23].”
  • Azole derivatives were developed mostly in the 1980s and 1990s and represent the largest class of antifungal agents used today in clinical medicine.

    “Azole derivatives was the next class of antifungals, developed mostly in the 1980s and 1990s [23,24]. They represent the largest class of antifungal agents used today in clinical medicine [35].”

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.
