Abstract

Flavonoids are widely distributed as secondary metabolites produced by plants and play important roles in plant physiology, having a variety of potential biological benefits such as antioxidant, anti-inflammatory, anticancer, antibacterial, antifungal and antiviral activity. Different flavonoids have been investigated for their potential antiviral activities and several of them exhibited significant antiviral properties in in vitro and even in vivo studies. This review summarizes the evidence for antiviral activity of different flavonoids, highlighting, where investigated, the cellular and molecular mechanisms of action on viruses. We also present future perspectives on therapeutic applications of flavonoids against viral infections.

  • The broadness of the O-H band suggests strong hydrogen bonding interactions characteristic of phenolic compounds.

    “The broadness of this band suggests strong hydrogen bonding interactions, which are characteristic of phenolic compounds [37,38].”

    From Comparative Analysis of Infusions and Ethanolic Extracts of Annona muricata Leaves from Colima, Mexico: Phytochemical Profile and Antioxidant Activity (2024) · cites this paper as [37]

    The Chemistry of flavonoids section describes flavonoid structures and substitutions, but does not discuss an O–H spectral band or its broadness. Searches for hydrogen bonding, FTIR, and O–H stretching found no passage connecting a broad band to hydrogen bonding in phenolic compounds. (LLM, conf=0.74)

  • A broad IR band at 3338 cm−1 extending from 3042 to 3600 cm−1 is indicative of O-H stretching vibrations associated with hydroxyl groups in phenolic compounds, flavonoids, and other hydroxylated molecules.

    “Furthermore, a broad band at 3338 cm−1, extending from 3042 to 3600 cm−1, is indicative of O-H stretching vibrations, commonly associated with hydroxyl groups in phenolic compounds, flavonoids, and other hydroxylated molecules.”

    From Comparative Analysis of Infusions and Ethanolic Extracts of Annona muricata Leaves from Colima, Mexico: Phytochemical Profile and Antioxidant Activity (2024) · cites this paper as [37]

    The Introduction’s ‘Chemistry of flavonoids’ section discusses flavonoid structures and modification by hydroxylases, but does not interpret infrared bands. Searches for 3338 cm−1, the 3042–3600 cm−1 range, and FTIR/O–H stretching found no passage addressing the claimed band assignment; page numbers were not available in our copy. (LLM, conf=0.76)

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.
