Abstract

The novel arylamidine T-2307 exhibits broad-spectrum in vitro and in vivo antifungal activities against clinically significant pathogens. Previous studies have shown that T-2307 accumulates in yeast cells via a specific polyamine transporter and disrupts yeast mitochondrial membrane potential. Further, it has little effect on rat liver mitochondrial function.

  • T-2307 has high selectivity for fungal mitochondria over mammalian cells.

    “T-2307 has high selectivity for fungal mitochondria over mammalian cells, which makes it a potent drug candidate for fungal infection (34, 39).”
  • T-2307 is effective against drug-resistant fungal isolates both in vitro and in vivo, including echinocandin-resistant C. albicans and Candida glabrata and azole-resistant C. albicans.

    “Moreover, T-2307 is effective against drug-resistant fungal isolates both in vitro and in vivo, which highlights its potent antifungal activities against echinocandin-resistant C. albicans and Candida glabrata and azole-resistant C. albicans (29, 32–34).”
  • ATI-2307 is a first-in-class arylamidine that disrupts yeast cellular respiration by inhibiting mitochondrial respiratory chain complexes III and IV.

    “It is a first-in-class arylamidine with a novel antifungal mechanism: the disruption of yeast cellular respiration via inhibition of mitochondrial respiratory chain complexes III and IV.”

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.
