Molecular mechanisms of anti-inflammatory activity mediated by flavonoids

Abstract

Flavonoids (or bioflavonoids) are naturally occurring compounds, ubiquitous in all vascular plants. These compounds have been considered to possess anti-inflammatory properties, both in vitro and in vivo. Although not fully understood, these health-promoting effects have been mainly related to their interactions with several key enzymes, signaling cascades involving cytokines and regulatory transcription factors, and antioxidant systems. The biological effects of flavonoids will depend not only on these pharmacodynamic features but also on their pharmacokinetics, which are dependent on their chemical structure, administered dose schedule and route of administration. Thus, the therapeutic outcome mediated by flavonoids will result from a complex and interactive network of effects, whose prediction require a deep and integrated knowledge of those pharmacokinetic and pharmacodynamic factors. The aim of the present review is thus to provide an integrated update on the bioavailability and biotransformation of flavonoids and the mechanisms of activity at the molecular, cellular, organ and organism levels that may contribute to their anti-inflammatory effects.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Nitric oxide is produced in large quantities by inducible nitric oxide synthase in activated macrophages and neutrophils during defence and immunological reactions.

    “Nitric oxide is produced in large quantities by the inducible nitric oxide synthases (iNOS) in activated macrophages and neutrophils during defence and immunological reactions.”
  • ROS and RNS play important roles in inflammation as trigger elements or signalling messenger molecules.

    “In addition these reactive species play important roles in inflammation by being trigger elements or by being signalling messenger molecules.”
  • Overproduction of ROS and RNS may be responsible for damage at inflammatory sites.

    “Nevertheless, their overproduction may be responsible for damage at inflammatory sites.”
  • Hydrogen peroxide can oxidise halide ions to hypochlorous acid, which can react with amines to produce chloramines, some of which are very toxic.

    “Peroxide hydrogen can also oxidise halide ions (Cl-) to hypochlorous acid (HOCl), which is a strong oxidant that can react with amines producing chloramines, some of them being very toxic [18,19,20,21,22].”
  • Essential oils may possess anti-inflammatory activities of interest in food, cosmetic, and human health.

    “Essential oils are complex mixtures isolated from aromatic plants which may possess antioxidant and anti-inflammatory activities of interest in thye food and cosmetic industries as well as in the human health field.”

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.
