Abstract

Compared with traditional de novo drug discovery, drug repurposing has become an attractive drug discovery strategy due to its low-cost and high efficiency. Through a comprehensive analysis of the candidates that have been identified with drug repositioning potentials, it is found that although some drugs do not show obvious advantages in the original indications, they may exert more obvious effects in other diseases. In addition, some drugs have a synergistic effect to exert better clinical efficacy if used in combination. Particularly, it has been confirmed that drug repositioning has benefits and values on the current public health emergency such as the COVID-19 pandemic, which proved the great potential of drug repositioning. In this review, we systematically reviewed a series of representative drugs that have been repositioned for different diseases and illustrated successful cases in each disease. Especially, the mechanism of action for the representative drugs in new indications were explicitly explored for each disease, we hope this review can provide important insights for follow-up research.

  • The conventional pathway for novel drug discovery, development, and regulatory approval can span approximately 15 years, rendering it inadequate to address immediate clinical demands posed by resistant Candida infections.

    “Yet, the conventional pathway for novel drug discovery, development, and regulatory approval can span approximately 15 years, rendering it inadequate to address the immediate and growing clinical demands posed by resistant Candida infections [14, 15].”

    From Statins as Antifungal Agents: A Review on Drug Repurposing and Nanotechnology-Driven Delivery Strategies (2025) · cites this paper as [14]

    The Introduction (page unavailable) estimates that developing a new drug takes 12–17 years, supporting the approximately 15-year figure. The Antimicrobial repositioning section (page unavailable) says new treatments are urgently needed for antimicrobial resistance, but it does not specifically establish that the conventional pathway is inadequate for the immediate clinical demands of resistant Candida infections.

  • The drug development process can take approximately 12-17 years.

    “Completing these stages can take approximately 12–17 years [14].”

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.
