Description
Technical field:
The invention belongs to the medical compounds field, be specifically related to a kind of come from the Chinese medicinal materials xanthorrhiza have tetrahydro-anthraquinone compounds Prisconnatacin of anti-tumor activity and preparation method thereof, with and application in the preparation antitumor drug.
Background technology:
Medicinal plant is from the existing so far kind more than 5,000 of " Shennong Bencaojing " record, and the clinical kind more than 1,000 that also has commonly used plays an important role for human opposing various diseases from ancient times to the present always.After the seventies in 20th century, modern separation technology extensively rose, the isolating active natural product had become the human new drug of excavating as new drug or as the precursor compound of developing new drug from the plant with long medicinal history, overcomes the breach of complex disease.In recent years, international medical giant has invested Chinese abundant resources of medicinal plant to sight especially, by setting up the external of integral framework and activity in vivo screening model, traditional Chinese medicinal components and monomeric compound thereof are carried out full scan, therefrom excavate efficient, low toxicity, novel structure is easy to the bioactive natural product of structural modification and transformation, as the medicine or the lead drug of treatment cancer, HIV and sudden communicable disease.
Cancer rises to gradually to threatening No. second killer of human health, and what make that medical circle puzzles is also not have good medicine can be applied to the clinical cancer of eliminating at present.Anthracene nucleus class (anthracyclines) medicine is a medicine of using maximum treatment cancers at present clinically, it also is relatively effective medicine, this class medicine mainly contains Zorubicin (doxorubicin), daunomycin (daunomycin), mitoxantrone (mitoxantrone), epirubicin (epirubicin), idarubicin (idarubicin), be the derivative of anthraquinone analog compound, have the effect of inducing apoptosis of tumour cell.But the selectivity of but finding them in secular clinical use gradually is low, when suppressing tumor propagation, normal cell also there is very big lethality, cause very strong toxic side effect, weak show as vomiting, weak, apocleisis, dizziness, serious finds that then heart is had serious damage, even cerebral nerve also had destruction, limited their uses clinically.Therefore, it is little to seek new toxic side effect, and the medicine of the treatment cancer of wide material sources has seemed urgent day by day.
Xanthorrhiza is the root of Rubiaceae South Mountain flower (Prismatomeris connata), as a kind of Chinese medicinal materials among the people, has the history of being used as medicine of two thousand years, be mainly used in treatment hepatitis, pneumonia, leukemia, diseases such as thalassemia, especially the treatment for silicosis has unique effect.This plant is rich in a large amount of anthraquinone analog compounds, has report to show that anthraquinone analog compound is the activeconstituents of this plant.From this plant, seek the active quinones of efficient, low toxicity, develop, have far-reaching researching value and social effect as the medicine or the prodrug of treatment cancer with antitumor action.
Summary of the invention:
First purpose of the present invention provides a kind of new tetrahydro-anthraquinone compounds Prisconnatacin with antitumor action who obtains that separates from the Chinese medicinal materials xanthorrhiza, its structure is suc as formula shown in (I).
Tetrahydro-anthraquinone compounds Prisconnatacin of the present invention, concrete structure is suc as formula shown in (I).

Second purpose of the present invention provides the preparation method suc as formula the tetrahydro-anthraquinone compounds Prisconnatacin shown in (I).This preparation method may further comprise the steps:
(a) pulverize xanthorrhiza is dried in the shade back, use the aqueous ethanolic solution lixiviate, after vat liquor concentrates crude extract;
(b) crude extract is suspended in water, use sherwood oil, ethyl acetate extraction successively, after acetic acid ethyl acetate extract concentrated, through silica gel column chromatography, with the chloroform-methanol is eluent, and from 95: 5~50: 50 gradient elutions of volume ratio, the component that gradient elution is got off can be that 3: 1 solution system unfolded components are again through silica gel column chromatography with chloroform-acetone volume ratio in thin-layer chromatography, with chloroform-acetone volume ratio is 5: 1 solution system wash-out, yellow powder shape Compound P risconnatacin.
Aqueous ethanolic solution in the described step (a) is preferably the aqueous ethanolic solution of volume fraction 95%.
The present invention proves that by experiment tetrahydro-anthraquinone compounds Prisconnatacin of the present invention can effectively suppress the propagation of kinds of tumor cells, can be used as antitumor drug and prodrug is developed, and can be receivable any one formulation on the medicine.
Therefore the 3rd purpose of the present invention provides the application of tetrahydro-anthraquinone compounds Prisconnatacin in the preparation antitumor drug.
Tetrahydro-anthraquinone compounds Prisconnatacin anti-tumor activity height of the present invention can be used to prepare antitumor drug, and it stems from traditional Chinese medicine material xanthorrhiza, and the source is sufficient, and separation method is simple, and toxicity is little, and is safe in utilization.The active tetrahydro-anthraquinone compounds of natural origin is less, and Compound P risconnatacin is simple in structure, can be used as the precursor compound of antitumor drug, on existing active basis, carry out further structural modification and transformation, improve its antineoplastic targeting and high efficiency, be used for exploitation treatment liver cancer, lung cancer, mammary cancer and leukemic medicine, its development and application prospect is very wide.
