Problems solved by technology

Although chemotherapeutic drugs have a certain effect on cancer, they have large toxic and side effects. The curative effect of Chinese patent medicines on cancer is generally low. For example, the remission rate of ginseng and lotus jelly on lung and gastric cancer is only 3.5%, and the curative effect is not ideal.

Embodiment 1

[0013] Embodiment 1: a kind of anticancer medicine annonaceous lactone monomer compound (itrabin) extraction method

[0014] An anticancer drug annonaceous lactone monomer compound, which is an anticancer monomer compound extracted from cherimoya seeds. Its preparation method is that after the custard apple seeds are air-dried, they are crushed into coarse powder, and first cold-extracted with 10 times the amount of petroleum ether (at room temperature) for 3 times (at room temperature), each time for 2 days; the petroleum ether is recovered to obtain a red oily liquid, which is placed at room temperature, and there is a large amount of The white precipitate is separated out, and the white precipitate is filtered out, and the white precipitate is subjected to repeated silica gel column chromatography; with sherwood oil, sherwood oil-ethyl acetate, ethyl acetate-methanol gradient elution, a kind of annonaceous lactone monomer compound ( itrabin).

Embodiment 2

[0015] Embodiment 2: a kind of anticancer medicine anemone lactone monomer compound, it is characterized in that white granular solid, easily soluble in organic solvents such as ethyl acetate, methanol, chloroform. It is identified as itrabin, and its chemical structural formula is as follows:

[0016]

Embodiment 3

[0017] Embodiment 3: the inhibitory action of a kind of anemone lactone monomer compound (itrabin) to human liver cancer cell

[0018] 1. Cell culture:

[0019] SMMC-7721 or HepG2 cell lines were inoculated in culture flasks, and RPMI-1640 culture solution (containing 10% calf serum, penicillin 100u / ml, streptomycin 100ug / ml) was added, and the cells were incubated at 37°C and 5% CO 2 Cultured in an incubator, the cells grow in a single layer adherent to the wall, passaged every 3 to 5 days, digested with 0.25% trypsin for 3 minutes, blown with the culture medium to make a cell suspension, and then inoculated.

[0020] 2. Drug treatment

[0021] Cells in the logarithmic growth phase were divided into 2×10 5 / ml inoculated in a cell culture flask, and after the cells were completely adhered to the wall (about 4 hours), the culture medium containing the drug was added and cultured for a predetermined time. The experimental drug is an anemone lactone monomer compound (itrabin)...

Abstract

An anticancer annona lactone monomer 'itrabin' for preventing and treating liver cancer is prepared from the annona seeds through drying, breaking, immersing in petroether, recovering petroether to obtain red oily liquid, laying aside, filtering to obtain white deposit, chromatography, and eluting.

Description

1. Technical field [0001] The invention relates to an anticancer drug, in particular to an anemone lactone monomer compound extracted from cherimoya seeds as a raw material and its application in the preparation of an anticancer drug. 2. Background technology [0002] Cancer is a formidable enemy that endangers human health. There are about 1.6 million new cases of cancer in my country every year, and about 1.3 million people die of cancer every year. The number of deaths due to cancer in the country is increasing year by year. my country has a high incidence of liver cancer, gastric cancer, esophageal cancer, breast cancer, and lung cancer. The region has a high cancer mortality rate. [0003] There are currently no effective drugs that cure most cancer patients. Although chemotherapeutic drugs have a certain effect on cancer, they have large toxic and side effects. The curative effect of Chinese patent medicines on cancer is generally low. For example, the remission rate ...
