Description

A kind of flavonol cpds
Technical field
The present invention relates to a kind of flavonol cpds---2 "-hydroxyl-3 "-alkene-dehydration Icaritin, and the preparation method of this compound and be the pharmaceutical composition of activeconstituents, and the application in treatment inflammation medicine with this compound.
Background technology
In recent years, in the research of anti inflammatory immunity medicine, Chinese medicine reaches characteristics such as aboundresources less because of its good drug efficacy, untoward reaction, more and more receive people's attention.The anti inflammatory immunity medicine is meant inflammatory reaction inhibited, immunoreation is had one type of medicine of inhibition or enhancing and regulating effect.The immunity system of body is the network system of a complicacy; The change of immune certain index often causes the variation of other indexs of body immune system; The anti inflammatory immunity pharmacology has been deep into cell levels and gene level, comprises researchs such as second messenger, nf in cytokine and acceptor thereof, lipoids inflammatory mediator, nitrogen protoxide, active oxygen, the cell.Along with improving constantly of anti-inflammatory pharmacological research method, the especially widespread use of Protocols in Molecular Biology in Chinese medicine anti-inflammatory pharmacological research, researching and developing the new natural drug activeconstituents with anti-inflammatory activity becomes focus gradually.Chinese medicine with antiinflammatory immunity function relates to multiple natural phant kind; Like trypterygine, Stem of Orientoine, the coptis, Chinese herbaceous peony, the Radix Astragali, glossy ganoderma, Herba Epimedii etc., activeconstituents relates to polysaccharide, glycosides, vegeto-alkali, lactone, steroidal, tonka bean camphor, anthraquinone, flavones, tannin, volatilization wet goods.
It is found that flavonoid compound has effects such as anti-inflammatory, antiviral, cholagogic, cardiac stimulant, calmness and analgesia the end of the sixties, found again afterwards that it had anti-oxidant, anti-ageing, immunomodulatory and effect such as antitumor.Epimedium flavonoids on croton oil induced mouse ear edema, acetic acid-induced increase in capillary permeability in mice, carrageenan induced paw edema in mice induced by croton oil and meat Ya tissue significantly inhibited effect on adjuvant arthritis in rats with primary and secondary paw swelling was significantly inhibited paw swelling.
Up to now, do not have the report of the flavonol cpds 2 "-hydroxyl-3 "-alkene-dehydration Icaritin of novel structure of the present invention in the prior art, also not this compound as effective ingredient in the relevant report of treatment aspect the disease.
Summary of the invention
The object of the present invention is to provide a kind of new flavonol cpds with pharmaceutical use.
Another object of the present invention provides a kind of preparation method of flavonol cpds.
It is the pharmaceutical composition of activeconstituents with the flavonol cpds that further aim of the present invention provides a kind of.
Another purpose of the present invention provides above-mentioned flavonol cpds or the purposes of compsn in preparation anti inflammatory immunity medicine.
Inventors of the present invention isolate a kind of new from dry Herba Epimedii (Epimedium brevicornum Maxim) herb, and it is active to have multiple valuable drug, and these activity are that existing Herba Epimedii plant milk extract is not available.
Flavonol cpds provided by the invention has following structural formula:
Figure G2008102334285D00021
Flavonol cpds provided by the invention is extraction separation from the Herba Epimedii herb, and this method may further comprise the steps:

The anti-inflammatory action of the flavonol cpds of structural formula (1) comprises following testing sequence:
1, material and method
1.1 the cell cultures cell is inoculated in 24 well culture plates after going down to posterity in containing the clear high sugared DMEM substratum of 10% tire ox.Being divided into is three groups, the positive controls (LPS1mg/L handles 18h) that blank control group (no medicine handle with LPS), LPS handle, compound 1 (be respectively 0.5,2.5 and 12.5mg/L)+LPS treatment group, LPS and compound 1 are handled 18h simultaneously, every group respectively three parallel.
1.2 the toxicological evaluation of compound 1 is used the MTT detection method and is estimated.Take the logarithm vegetative period RAW cell inoculation in 96 well culture plates, 1 * 10 5Individual cells/well, 37 ℃, 5%CO 2After cultivating 20h under the condition, add 20 μ LMTT (5mg/mL) again and continue to cultivate 4h, add DMSO150 μ L dissolving then, measure each hole light absorption value (OD value) in the 595nm place, calculate the relevant motility rate of cell with enzyme-linked immunosorbent assay instrument.
1.3 the mensuration of cytokine is got cultured cells supernatant 100 μ L, according to the procedure operation of cytokine ELISA detection kit.
2, result
2.1 behind RAW264.7 monocyte-scavenger cell 20h that the toxicological evaluation 0.5,2.5 of compound 1 and the compound of 12.5mg/L concentration 1 are handled; Handling positive controls with the blank group with LPS compares; The cell motility rate does not have significant difference, explains that 1 pair of RAW264.7 cell of compound does not have cytotoxic effect (description of drawings Fig. 2).
2.2 after 1 pair of external LPS inductive RAW264.7 scavenger cell-monocyte TNF-α synthetic of compound influenced blank control group RAW264.7 cell cultures 18h, excretory TNF-alpha levels was respectively 1433.5 ± 417pg/mL.The secretion of TNF-α significantly increases behind LPS (1mg/L) the processing 18h, reaches 4884 ± 600pg/mL.After adding compound 1 (0.5-12.5mg/L) and LPS co-processing, there is concentration dependent (description of drawings Fig. 3) in RAW264.7 excretory TNF-α.Compare with the positive controls that LPS handles; 0.5 can suppress TNF-α significantly with the compound 1 of 12.5mg/L concentration; Inhibiting rate is respectively 17.1% (p < 0.01); 55.6% (p < 0.01), the compound 1 of 2.5mg/L concentration can suppress TNF-α, but difference not significantly (p>0.05) inhibiting rate be 20.1%.
