Ethanolic Extract of Propolis and CAPE as Cardioprotective Agents against LPS and IFN-α Stressed Cardiovascular Injury.

The inflammatory process is triggered by several factors such as toxins, pathogens, and damaged cells, promoting inflammation in various systems, including the cardiovascular system, leading to heart failure. The link between periodontitis as a chronic inflammatory disease and cardiovascular disease is confirmed. Propolis and its major component, caffeic acid phenethyl ester (CAPE), exhibit protective mechanisms and anti-inflammatory effects on the cardiovascular system.

In Vitro Anti-Inflammatory Activity of Methyl Derivatives of Flavanone.

Inflammation plays an important role in the immune defense against injury and infection agents. However, the inflammatory chronic process may lead to neurodegenerative diseases, atherosclerosis, inflammatory bowel diseases, or cancer. Flavanones present in citrus fruits exhibit biological activities, including anti-oxidative and anti-inflammatory properties.

The Phenolic Profile and Anti-Inflammatory Effect of Ethanolic Extract of Polish Propolis on Activated Human Gingival Fibroblasts-1 Cell Line.

Propolis, owing to its antibacterial and anti-inflammatory properties, acts as a cariostatic agent, capable of preventing the accumulation of dental plaque and inhibiting inflammation. The anti-inflammatory properties of propolis are attributed to caffeic acid phenethyl ester (CAPE), which is present in European propolis. The objective of the conducted study was to assess the anti-inflammatory effects of the Polish ethanolic extract of propolis (EEP) and isolated CAPE on stimulated with LPS and IFN-α, as well as the combination of LPS and IFN-α.

Santin (5,7-Dihydroxy-3,6,4'-Trimetoxy-Flavone) Enhances TRAIL-Mediated Apoptosis in Colon Cancer Cells.

TRAIL (Tumor necrosis factor-Related Apoptosis-Inducing Ligand) has the ability to selectively kill cancer cells without being toxic to normal cells. This endogenous ligand plays an important role in surveillance and anti-tumor immunity. However, numerous tumor cells are resistant to TRAIL-induced apoptosis.

[Apigenin inhibits release and gene expression of monocyte chemoattractant protein 1 (MCP-1) in J774.2 macrophages].

Monocyte chemoattractant protein-1(MCP-1) is secreted by activated macrophages and endothelial cells, and is involved in the pathogenesis of cardiovascular and neurodegenerative disorders. There is need to develop drugs that inhibit excessive infiltration of monocytes and lymphocytes to the arterial wall and central nervous system. The aim of this study was to evaluate the effect of apigenin on the synthesis and release of MCP-1 by J774.

Effect of apigenin, kaempferol and resveratrol on the expression of interleukin-1beta and tumor necrosis factor-alpha genes in J774.2 macrophages.

Flavonoids have been reported to bring benefits in lowering inflammation, oxidative stress and exert positive effects in cancer and cardiovascular and chronic inflammatory diseases. Apigenin, kaempferol and resveratrol present in fruits, vegetables and grain were investigated for their effect on the synthesis of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) at transcriptional level in lipopolysaccharide (LPS)-stimulated J774.2 macrophages.

Effect of kaempferol on the production and gene expression of monocyte chemoattractant protein-1 in J774.2 macrophages.

Monocyte chemoattractant protein-1 (MCP-1) is produced by activated macrophages, and is involved in pathogenesis of cardiovascular and neurodegenerative disorders. There is a need to develop drugs that inhibit excessive infiltration of monocytes and lymphocytes to the arterial wall and central nervous system. The aim of this study was to evaluate the effect of kaempferol on the (MCP-1) gene expression and MCP-1 protein release by J774.

Synthesis and tumoricidal activity evaluation of new morin and quercetin sulfonic derivatives.

Flavonoids are a group of naturally occurring compounds with interesting medical properties, such as antiinflammatory, antiallergic, antiviral, antibacterial and antitumor activities. In our experiments we were trying to examine the tumoricidal activity of newly synthesized derivatives of two flavonoids: 3,5,7,2',4'-pentahydroxyflavone (morin) and 3,5,7,3',4'-pentahydroxyflavone (quercetin). These derivatives were: natrium salt of morin-5'-sulfonic acid (NaMSA), natrium salt of quercetin-5'-sulfonic acid (NaQSA), complex of Mg2+ with quercetin-5'-sulfonic acid (QSA), complex of iron(II) with QSA.
