|Chlorogenic acid enhances the effects of 5-fluorouracil in human hepatocellular carcinoma cells through the inhibition of extracellular signal-regulated kinases.[Pubmed: 25714249]|
|There is an urgent need to search for novel chemosensitizers in the field of cancer therapy. Chlorogenic acid (CGA), a type of polyphenol present in the diet, has many biological activities.
METHODS AND RESULTS:
The present study is designed to explore the influence of CGA on the effects of 5-fluorouracil (5-FU) on human hepatocellular carcinoma cells (HepG2 and Hep3B). Treatment with 5-FU induced the inhibition of hepatocellular carcinoma cells' proliferation, and the combined treatment with CGA enhanced this inhibition. 5-FU also increased the production of reactive oxygen species (ROS). The combination of 5-FU and CGA led to a more prominent production of ROS and significantly inactivated ERK1/2, although CGA and 5-FU exerted no significant changes when used alone. A previous report has shown that ROS are upstream mediators that inactivate ERK in hepatocellular carcinoma cells. Combined with our results, this indicates that the combination of 5-FU and CGA leads to the inactivation of ERK through the overproduction of ROS. This mediates the enhancement of 5-FU-induced inhibition of hepatocellular carcinoma cells' proliferation, that is, CGA sensitizes hepatocellular carcinoma cells to 5-FU treatment by the suppression of ERK activation through the overproduction of ROS.
CGA has shown potential as a chemosensitizer of 5-FU chemotherapy in hepatocellular carcinoma.

|In vitro and in vivo antioxidant properties of chlorogenic acid and caffeic acid.[Pubmed: 20933071 ]|
|Dietary polyphenols are thought to be beneficial for human health as antioxidants. Coffee beans contain a common polyphenol, Chlorogenic acid. Chlorogenic acid is the ester of caffeic acid and quinic acid. Although these polyphenols have received much attention, there is little evidence indicating a relationship between the effect and the rate of absorption.
METHODS AND RESULTS:
In this study, we focused on the beneficial effects of Chlorogenic acid and caffeic acid, a major metabolite of Chlorogenic acid. We carried out in vitro and in vivo experiments. In the in vitro study, caffeic acid had stronger antioxidant activity than that of Chlorogenic acid. The uptake of Chlorogenic acid by Caco-2 cells was much less than that of caffeic acid. The physiological importance of an orally administered compound depends on its availability for intestinal absorption and subsequent interaction with target tissues. We then used an intestinal ischemia-reperfusion model to evaluate antioxidant activities in vivo.
We found that both Chlorogenic acid and caffeic acid had effects on intestinal ischemia-reperfusion injury. Since caffeic acid has a stronger antioxidant activity than that of Chlorogenic acid and Chlorogenic acid is hydrolyzed into caffeic acid in the intestine, it is possible that caffeic acid plays a major role in the protective effect of Chlorogenic acid against ischemia-reperfusion injury.

|Chlorogenic acid modifies plasma and liver concentrations of: cholesterol, triacylglycerol, and minerals in (fa/fa) Zucker rats.[Pubmed: 12550056]|
|Chlorogenic acid, a phenolic compound found ubiquitously in plants, is an in vitro antioxidant and metal chelator. Some derivatives of Chlorogenic acid are hypoglycemic agents and may affect lipid metabolism. Concentrations of cholesterol and triacylglycerols are of interest due to their association with diseases such as non-insulin-dependent-diabetes- mellitus and obese insulin resistance.
METHODS AND RESULTS:
As little is known about the effects of Chlorogenic acid in vivo, studies using obese, hyperlipidemic, and insulin resistant (fa/fa) Zucker rats were conducted to test the effect of Chlorogenic acid on fasting plasma glucose, plasma and liver triacylglycerols and cholesterol concentrations. Aditionally, the effects of Chlorogenic acid on selected mineral concentrations in plasma, spleen, and liver were determined. Rats were implanted with jugular vein catheters. Chlorogenic acid was infused (5 mg/Kg body weight/day) for 3 weeks via intravenous infusion. Chlorogenic acid did not promote sustained hypoglycemia and significantly lowered the postprandial peak response to a glucose challenge when compared to the same group of rats before Chlorogenic acid treatment. In Chlorogenic acid-treated rats, fasting plasma cholesterol and triacylglycerols concentrations significantly decreased by 44% and 58% respectively, as did in liver triacylglycerols concentrations (24%). We did not find differences (p > 0.05) in adipose triacylglycerols concentration. Significant differences (p < 0.05) in the plasma, liver, and spleen concentration of selected minerals were found in Chlorogenic acid-treated rats.
In vivo, Chlorogenic acid was found to improve glucose tolerance, decreased some plasma and liver lipids, and improve mineral pool distribution under the conditions of this study.

|Chlorogenic acid suppresses interleukin-1β-induced inflammatory mediators in human chondrocytes.[Pubmed: 25674248]|
|We investigated the anti-inflammatory properties of Chlorogenic acid (CGA) in interleukin-1β-induced chondrocytes. The nitric oxide (NO) and prostaglandin E2 (PGE2) were detected by Griess and Enzyme-linked immunosorbent assay (ELISA) respectively. Quantitative real-time PCR and western blot were performed to measure the expression of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2. Our results indicate that Chlorogenic acid inhibited the production of NO and PGE2 as well as the expression of iNOS and COX-2 in chondrocytes. Our data suggest that Chlorogenic acid possess potential value in the treatment of OA.|

|Involvement of TLR2 and TLR9 in the anti-inflammatory effects of chlorogenic acid in HSV-1-infected microglia.[Pubmed: 25744394]|
|There is no effective medication to date for herpes simplex virus encephalitis (HSE). In this study, we investigated the anti-inflammatory effect of Chlorogenic acid (CGA) on herpes simplex virus (HSV)-1-induced responses in BV2 microglia.
METHODS AND RESULTS:
The cellular model was established with BV2 cells stimulated by HSV-1 and then treated with CGA at different concentrations. Cell viability was assayed by the MTT assay. The mRNA expression of Toll-like receptor (TLR)-2, TLR9 and myeloid differentiation factor88 (Myd88) was assayed by real-time quantitative PCR, and the protein expression was assayed by flow cytometry or Western blotting. Tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were measured by ELISA as well as real-time quantitative PCR. Nuclear NF-κB p65 protein was assayed by Western blotting.
The cell survival rate was significantly improved after CGA treatment, and CGA prevented increases in TLR2, TLR9 and Myd88 following HSV-1 challenge in BV2 cells both at the mRNA and protein levels. Moreover, CGA could attenuate HSV-induced TNF-α and IL-6 release into the supernatant. The mRNA levels of TNF-α and IL-6 were also significantly inhibited by CGA. The expression of NF-κB p65 increased significantly in the nucleus in HSV-1-stimulated microglia but could be reduced by CGA.
CGA inhibits the inflammatory reaction in HSE via the suppression of TLR2/TLR9-Myd88 signaling pathways. CGA may serve as an anti-inflammatory agent and provide a new strategy for treating HSE.

|Anti-hepatitis B virus activity of chlorogenic acid, quinic acid and caffeic acid in vivo and in vitro.[Pubmed: 19463857 ]|
|Chlorogenic acid and its related compounds are abundant plant polyphenols that have a diverse antiviral activity.
METHODS AND RESULTS:
In this study, HepG2.2.15 cells and duck hepatitis B virus infection model were used as in vitro and in vivo models to evaluate their anti-HBV activity. In the cell model, all the three compounds inhibited HBV-DNA replication as well as HBsAg production. Chlorogenic acid and caffeic acid also reduced serum DHBV level in DHBV-infected duckling model. Moreover, the anti-HBV activity of crude extracts of coffee beans, which have a high content of Chlorogenic acid, was studied.
Both the extracts of regular coffee and that of decaffeinated coffee showed inhibitory effect on HBV replication.
