Abstract

Flavonoids possess several biological/pharmacological activities including anticancer, antimicrobial, antiviral, anti-inflammatory, immunomodulatory and antioxidant. The aim of this study was to evaluate the effect of flavonoids on macrophage physiology. For this purpose we selected some flavonoids belonging to the most common and abundant groups (flavonols--quercetin and kaempferol; flavones--diosmetin, apigenin, chrysin and luteolin; isoflavones--genistein and daidzein and flavanones--hesperetin). We decided to use primary bone marrow-derived macrophages (BMDM) as cellular model, since they represent a homogenous, non-transformed population of macrophages that can be stimulated in vitro to proliferate by macrophage colony-stimulating factor (M-CSF) or activated by LPS. In this regard, we demonstrated that most of the flavonoids assayed reduce macrophage M-CSF-induced proliferation without affecting cellular viability. Moreover, some flavonoids also inhibit TNFalpha production as well as iNOS expression and NO production in LPS-activated macrophages, an effect that has been associated with the inhibition of the NF-kappaB pathway. We also found that luteolin and quercetin are able to stimulate the expression of the anti-inflammatory cytokine IL-10 at low concentrations (<50microM). Analysis of the structure-activity relationship showed that four hydroxylations at positions 5, 7, 3' and 4', together with the double bond at C(2)-C(3) and the position of the B ring at 2, seem to be necessary for the highest anti-inflammatory effect.

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.
