Abstract

The invention discloses application of tangeretin serving as sensitizer used for preparing chemotherapeutics used for curing a solid tumor. An in vitro cell experiment shows that when concentration of 5-fluorouracil is 25ug\ml and 50ug\ml, tangeretin drug combination can strengthen antineoplastic activity of the 5-fluorouracil, and synergistic effects are shown to restrain growth of a human colon cancer cell HCT-116. When the concentration of the 5-fluorouracil is 25ug\ml, effects of 5-fluorouracil drug combination are the best. An animal experiment shows that drug combination of the tangeretin and the 5-fluorouracil has obvious inbibitional effects on growth of a mice transplant tumor S180 sarcoma, and a mice death rate caused by larger toxicity of chemotherapeutics 5-fluorouracil is reduced largely. The drug combination of the tangeretin and the 5-fluorouracil reduces a dosage of the 5-fluorouracil, so a side effect of mice reduced weight caused by the chemotherapeutics 5-fluorouracil can be relieved, and toxicity of the 5-fluorouracil to a mice is reduced.

Description

technical field [0001] The present invention relates to the use of flavonoid compound hesperetin, especially the use in pharmacy. Background technique [0002] Tumor is a disease that seriously endangers human health. Solid tumors refer to solid tumors, which can be detected clinically through inspections such as X-rays, CT scans, B-ultrasound or palpation. They are divided into two types: benign and malignant. Malignant tumor masses are also commonly referred to as cancers, and common clinical malignant solid tumors include lung cancer, neuroma, colorectal cancer, and sarcoma. [0003] Colorectal cancer is a malignant tumor of the digestive system that seriously endangers human health. About 1 million people are newly diagnosed with colorectal cancer every year in the world, and about 500,000 people die from it. The incidence of colorectal cancer is the third highest in the world, and it ranks the third in the death caused by cancer, seriously endangering human health. T...
