Quercetin is a flavonol compound that is widely distributed in the plant kingdom and has a variety of biological activities. Quercetin can fight free radicals, complex or capture free radicals to prevent lipid peroxidation in the body; it can directly inhibit tumors, and effectively exert anti-cancer and anti-cancer effects; it also has antibacterial, anti-inflammatory, anti-allergic, and prevention of diabetes complications.
Strong biological activity. In addition, quercetin also has the effects of lowering blood pressure, enhancing capillary resistance, reducing capillary fragility, lowering blood lipids, dilating coronary arteries, increasing coronary blood flow, etc. It also has an adjuvant therapeutic effect on patients with coronary heart disease and hypertension. Quercetin is non-toxic, so it is of great significance to the treatment and prevention of cancer, aging, and cardiovascular diseases, and has great development value.
Quercetin is a natural chelating agent that can chelate iron in the body, reduce iron overload in the body, and reduce oxidative damage caused by iron overload.
Quercetin has many functions such as anti-oxidation, scavenging free radicals, and inhibiting lipid peroxidation. It can resist oxidation, protect cardiovascular health, and also shows a good effect in anti-cancer. However, this type of research data comes from cytology experiments or animal experiments, and whether it works directly in humans remains to be verified.
In terms of anti-cancer, quercetin has many studies showing its inhibitory effect on various cancer cells. In terms of the specific mechanism of action, quercetin has a variety of biological effects, inhibiting a variety of enzymes in cancer cells to participate in cell proliferation and signal transduction pathways.
On the other hand, some studies have shown that quercetin has a certain synergistic effect when used in combination with commonly used chemotherapeutics or radiotherapy, and has certain application prospects. For example, quercetin can act on chemosensitization and radiosensitization chemotherapy as well as anti-radiation, protecting normal cells from the side effects of chemotherapy and radiotherapy. These advantages can significantly enhance its anti-cancer therapeutic effect. A variety of flavonols such as quercetin, kaempferol, myricetone have a certain preventive effect on pancreatic cancer, especially for smokers, the effect may be more obvious. To
Quercetin can play an anti-tumor effect by inducing tumor cell apoptosis. The expression of glucose transporter in primary liver cancer is significantly increased, and inhibition of its expression can be used as a new treatment direction for primary liver cancer. In the field of gastric cancer research, it has also been found that quercetin can induce cell apoptosis, by triggering mitochondrial apoptosis-dependent growth inhibition, thereby exerting an anti-tumor effect, which can be used as a new target for the treatment of gastric cancer.
