Abstract

We investigated the in vitro anti-inflammatory effects of Cinnamaldehyde, a cytokine production inhibitor isolated from an essential oil produced from the leaves of Cinnamomum osmophloeum Kaneh, and its mechanism of action. Although Cinnamaldehyde has been reported to have contact sensitizing properties at high concentration (mM), we found that low concentration of Cinnamaldehyde (muM) inhibited the secretion of interleukin-1beta and tumor necrosis factor alpha within lipopolysaccharide (LPS) or lipoteichoic acid (LTA) stimulated murine J774A.1 macrophages. Cinnamaldehyde also suppressed the production of these cytokines from LPS stimulated human blood monocytes derived primary macrophages and human THP-1 monocytes. Furthermore, Cinnamaldehyde also inhibited the production of prointerleukin-1beta within LPS or LTA stimulated human THP-1 monocytes. Reactive oxygen species release from LPS stimulated J774A.1 macrophages was reduced by Cinnamaldehyde. The phosphorylation of extracellular signal-regulated kinase 1/2 and c-Jun N-terminal kinase 1/2 induced by LPS was also inhibited by Cinnamaldehyde; however, Cinnamaldehyde neither antagonize the binding of LPS to the cells nor alter the cell surface expression of toll-like receptor 4 and CD14. In addition, we also noted that Cinnamaldehyde appeared to elicit no cytotoxic effect upon J774A.1 macrophages under our experimental conditions, although Cinnamaldehyde reduced J774A.1 macrophages proliferation as analysed by MTT assay. Our current results have demonstrated the anti-oxidation and anti-inflammatory properties of Cinnamaldehyde that could provide the possibility for Cinnamaldehyde's future pharmaceutical application in the realm of immuno-modulation.

  • Cinnamaldehyde inhibits secretion of IL-1β and TNF-α in LPS- or LTA-stimulated murine J774A.1 macrophages and suppresses these cytokines from LPS-stimulated human blood monocyte-derived primary macrophages and human THP-1 monocytes.

    “Cinnamaldehyde, isolated from an essential oil produced from the leaves of Cinnamomum osmophloeum, was reported to inhibit the secretion of IL-1β and TNF-α within LPS or lipoteichoic acid (LTA) stimulated murine J774A.1 macrophages. Cinnamaldehyde also suppressed the production of these cytokines from LPS stimulated human blood monocytes derived primary macrophages and human THP-1 monocytes [111].”
  • Cinnamaldehyde-mediated inhibition of cytokine production may be at least in part due to reduction of ROS release and of JNK and ERK within LPS-stimulated J774A.1 macrophages.

    “Cinnamaldehyde-mediated inhibition of cytokines production found by Chao et al. (2008) [111], and reported above, may be, at least on part, due to the reduction of ROS release as well as of those of JNK and ERK within LPS stimulated J774A.1 macrophages.”

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.
