Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a glycosyl β-elemene derivative and a preparation method and application thereof. Background technique [0002] β-elemene is a national second-class anticancer drug extracted from the rhizome of turmeric, a plant of Zingiberaceae, for the first time by Chinese researchers. It inhibits cancer cell proliferation, induces cancer cell apoptosis, inhibits cancer cell angiogenesis, and curbs cancer cell metastasis. , affecting telomerase activity and reversing the drug resistance of cancer cells to exert anti-tumor effects. Malignant tumors also have good curative effect, broad-spectrum anti-cancer activity and good anti-tumor application prospects. However, due to the shortcomings of β-elemene, such as poor solubility in water, low bioavailability, and inability to monitor and treat tumors in real time, it has a strong concentration and time dependence, which severely limits its cli...
