Abstract
The invention provides Artemeriosides A ‒ F (1-6), a pharmaceutical composition thereof, a preparation method and application thereof, and belongs to the technical field of medicines. The 6 sesquiterpene 6' -O-crotonyl beta-glucopyranoside shown in the structural formula (I) has a sesquiterpene-flavonol hybrid, artemeriosides A ‒ F (1-6) has an inhibiting effect on human liver cancer cell strains HepG2, huh7 and SK-hep-1, can form a pharmaceutical composition with a pharmaceutically acceptable carrier, and can be used for preparing anti-liver cancer drugs.
Description
Technical field:
The invention belongs to the technical field of medicines. In particular to 6 sesquiterpenes 6' -O-crotonyl beta-glucopyranoside, artemeriosides A-F (1-6), a preparation method and application thereof, and application of a pharmaceutical composition taking the compounds 1-6 as active ingredients in preparing medicines for resisting liver cancer.
The background technology is as follows:
As a gift for humans in nature, medicinal plants play an important role in protecting our health and are generally considered safer and milder in treating various diseases. Artemisia is one of the largest genera of Compositae, distributed in North America, europe, and Asia in the North temperate region. Some of these have been widely used in the treatment of various diseases, including cancer, malaria, hepatitis, cancer, inflammation and infection, possibly due to their diverse chemical compositions and their important medicinal properties. Artemisia annua (ARTEMISIA ANNUA L.), also known as Artemisia annua, is a well-known traditional Chinese medicine, and can be used for treating malaria. Chemical studies have found that sesquiterpenes, diterpenes, phenylpropionic acid, coumarin, flavonoids, volatile oil and the like exist in artemisia annua. Among them, artemisinin having a hydrogen peroxide bridge is the most well known molecule and also its unique molecule. Artemisinin has strong antimalarial activity but its solubility in oil and water is poor, thus limiting its use. Thus, its two chemically synthesized derivatives, artemisinin and artemether, have been developed as clinical therapeutic drugs for malaria and cure millions of patients [10]. Thus, a nobel physiological or medical prize of 2015 was awarded to Tu Youyou professor to bring her and other chinese scientists into an influential research effort to develop artemisinin as a novel antimalarial drug. Recently, the Artemisia annua has liver cancer resisting activity, and the main active ingredient of the Artemisia annua is flavonoid. Continuing to study, we isolated 6 sesquiterpenes 6' -O-crotonyl beta-glucopyranoside, artemeriosides A-F (1-6) from Artemisia annua. No report exists in Artemeriosides A-F (1-6) in the prior art, no report exists in a pharmaceutical composition taking the same as an active ingredient, and no report exists in the application of the pharmaceutical composition in preparing or treating liver cancer drugs.
The invention comprises the following steps:
The invention aims to provide a novel preparation method, a pharmaceutical composition and application of Artemeriosides A-F (1-6) with medicinal value shown in a formula (I). The invention separates and identifies 6 sesquiterpene 6' -O-crotonyl beta-glucopyranoside from Artemisia annua, artemeriosides A-F (1-6). The compound has an inhibiting effect on human liver cancer cell strains HepG2, huh7 and SK-Hep-1, and can be used for preparing anti-liver cancer drugs.
In order to achieve the above object of the present invention, the present invention provides the following technical solutions:
The invention provides 6 sesquiterpene 6' -O-crotonyl beta-glucopyranoside, artemeriosides A-F (1-6), and the structure is shown as the following formula (I):
The invention further provides a method for preparing the compounds 1-6 shown in the formula I, which comprises the steps of crushing 48kg of dried aerial parts of artemisia annua, extracting twice with 3 times of 90% ethanol, mixing the extracting solutions, concentrating under reduced pressure to obtain crude extract, dispersing the crude extract in water, and extracting with ethyl acetate to obtain 3.1kg of ethyl acetate extract. Subsequently, the ethyl acetate extract fraction was subjected to silica gel column chromatography and eluted with a gradient of acetone-petroleum ether volume ratio of 10:90,20:80, 30:70 and ethyl acetate to give 4 fractions Frs.A-D.
