Flavonoids in Plant Food and their Health Benefits

In our research, we strongly believe what Hippocrates (460-377 B.C.), the father of medicine, stated thousands of years before: "Let thy food be thy medicine and thy medicine be thy food鈥�.  Rapid advancements in food production after the green revolution and changing life style has made our regular diet nutritionally imbalanced. Now, not only the industrialized countries but rapidly developing countries of the world face significant challenges from epidemics of chronic disease that are directly or indirectly linked to diet, lifestyle and the environment. For example, deaths from cancer worldwide are projected to continue rising, World Health Organization has estimated 13.1 million deaths in 2030 due to cancer. Cancer treatment in many countries has already become a social-economic challenge due to the treatment and patient-care expenses and medical infrastructure required. We believe, prevention as the most cost-effective, long-term approach for controlling disorders such as cancer.  The last two decades of scientific evidence, epidemiological evidence and recent meta-analysis of prospective cohort studies clearly demonstrates the relationship between habitual adequate consumption of fruits and vegetables and reduce incidence of oxidative-stress and chronic inflammation regulated disorders. 

Our recent research were mainly focused on flavonoids, the major antioxidant components in fruits, which have remarkable power in preventing the development of chronic diseases and promoting human health and wellness. In particular, our research hypotheses is that some unique flavonoids in cool climate fruits such as apples and berries can play as the major biologically active components of our diet to reduce the risk of cardiovascular and neurodegenerative disorders and various cancers. My research team has been attempting to answer to the questions of: what are the most important types of dietary flavonoids? what amount of flavonoids are needed for the therapeutic efficacy? could isolated flavonoid supplements provide the efficacy and safety? what are their mechanism of action(s) at cellular level? Our applied research is designed to translate the new discoveries into functional foods and nutraceuticals. 

(A) Cardio-protective properties of fruit flavonoids and their products

Using pre-clinical studies, we have demonstrated that a specific apple flavonoid extract (AFE) possesses multiple target-based mechanisms toward the prevention and treatment of cardiovascular and coronary heart diseases. The apple flavonoids showed the reduction of the risk of atherosclerosis by remarkably decreasing the oxidation of low density lipoprotein (LDL)-cholesterol in vitro. When the diet of hypercholesterolemic male Golden Syrian hamsters was supplemented with the AFE, plasma total cholesterol and LDL-cholesterol levels were significantly reduced compared to the control. Similarly, when the extract was supplemented in the diet of hyperlipidemic male Wister rats, not only LDL-cholesterol level significantly reduced but also high density lipoprotein (HDL)-cholesterol level significantly increased. When lipopolysaccharide (LPS) was used to induce inflammation of Wister rats, pro-inflammatory markers (IL-6 and CRP) in blood were significantly reduced by the extracts indicating the anti-inflammatory properties. AFE and their constituent flavonoids inhibited the angiotensin converting enzyme (ACE), a therapeutic target of anti-hypertension drugs, at very low concentrations (20 nM to 3 碌M) in HUVEC cells. The dietary supplementation of AFE and a fruit-based functional beverage reduced the blood pressure of spontaneously hypertensive rats.

(B) Flavonoids-based natural health products for neurodegenerative diseases

Despite modern drug discovery approaches, no therapeutic product is available to halt the degenerative processes responsible for stroke, multiple sclerosis (MS) or Alzheimer鈥檚 disease. We have found a specific flavonoid fraction derived from apple peels (AF4) with strong neuroprotective and anti-inflammatory effects when examined in mice subjected to hypoxic-ischemic (HI) brain damage, an experimental model for stroke. Oral administration of AF4 (25 mg/kg/d) for at least three days prior to HI markedly reduced subsequent motor impairments, brain damage, and inflammation after an experimental stroke. AF4-mediated neuroprotection was accompanied by changes in gene expression suggestive of improved mitochondrial function and activation of pathways that promote cell survival. AF4 has also reduced clinical signs of MS in an experimental autoimmune encephalomyelitis (EAE) model of mice by decreasing neuroinflammatory damage in the spinal cord and improving the expression of genes necessary for remyelination. Similarly, flavonoids-rich fraction isolated from partridgeberry (Vaccinium vitis-idaea) exhibited cytoprotection ability in peroxyl radical-induced fibroblasts through activation of the transcription factor Nrf2-antioxidant responsive element (ARE) pathway and protection of rat primary cortical and hippocampal neurons against 尾-amyloid toxicity and oxygen-glucose deprivation-reperfusion-induced injury via suppression of inflammatory adipokines and regulation of hypoxia-inducible factor 1-alpha (HIF-1伪) and peroxisome proliferator-activated receptor gamma (PPAR纬).

(C) Novel anti-cancer therapeutic agents synthesized from food biomolecules:

To enhance the bioavailability and biological activities of flavonoids, we have synthesized a series of novel flavonoid derivatives with higher hydrophobicity. The lipase-catalyzed acylation of phloridzin (PZ) and isoquercetrin (Q3G) with six long chain fatty acids was optimized. We have identified an effective and safe flavonoid derivative with potential for treating hepatocellular carcinoma, acute monocytic leukemia, and breast cancer. The antiproliferative potency of fatty acid esters of PZ was comparable to the potency of the chemotherapeutic drugs. The fatty acid esters of PZ inhibited DNA topoisomerases II伪 activity that might induce G0/G1 phase arrest, induced apoptosis via activation of caspase-3, and decreased ATP level and mitochondrial membrane potential in HepG2 cells. Antiproliferative efficacy of one of the derivatives, docosahexaenoic acid acylated PZ (PZ-DHA) was investigated using a triple negative breast cancer cell line (MDA-MB-231). PZ-DHA, but not PZ, caused the death of MDA-MB-231 in vitro which was both time- and dose-dependent. PZ-DHA-induced apoptosis was indicated by DNA fragmentation and activation of caspase 3/7. PZ-DHA showed low cytotoxicity toward human normal cells. Anticancer efficacy observed in cell cultures and mice suggest PZ-DHA as a potential treatment for breast cancer. Advanced pre-clinical experiments of intravenous injection and oral administration of PZ-DHA using animal models are in progress.

(D) Prevention of omega-3 lipid oxidation by apple peel flavonoids

Natural food antioxidants for stabilization of omega-3 polyunsaturated fatty acid (PUFA) have received much attention due to the restrictions of synthetic antioxidants in foods in some countries. The effectiveness of quercetin glycosides (QG) in inhibiting lipid oxidation in oil-in-water emulsion systems when oxidation was induced by heat, light, peroxyl radical or ferrous ion was greater than that of 伪-tocopherol. Antioxidant activity of QG was greater than butylated hydroxytoluene in bulk fish oil. QG-rich ethanol extracts of apple peels strongly inhibited omega-3 PUFA oxidation. QG isolated from apple peels showed ability to stabilize omega-3 PUFA-oxidation induced heat.
