Abstract
An antivirus active compound used to prepare new medicine for duck's hepatitis B and bidirectional immune is prepared by one-step condensation of acetone and sedoneose anhydride extracted from Crassulaceae plant.
Description
The present invention relates to field of medicaments, is the compound that has antiviral activity about a kind of, a kind of active compound that is used for anti-duck hepatitis B virus of more specifically saying so.
Hepatitis B is one of main transmissible disease of harm humans health, and domestic have 10% population to carry hepatitis B surface antigen approximately.Though the medicine of treatment hepatitis B and the research of Hepatitis B virus vaccine thereof get along with at present, still do not have good specifics so far.The Crassulaceae plant is clearing heat and detoxicating at Ceng Zuowei among the people, dissipating blood stasis for subsidence of swelling and wound herbal medicine use, but to all further investigations of its intrinsic pharmaceutical activity.
The object of the present invention is to provide a kind of new new compound with anti-hepatitis B virus activities, and the method for synthesizing this new compound from the Crassulaceae plant milk extract.
The anti-hepatitis B virus activities compound of the present invention development is extraction from the herb of Crassulaceae plant eight treasures (choice ingredients of certain special dishes) (Helotylphin erythrostictum) or long medicine eight treasures (choice ingredients of certain special dishes) (H.spectabite), Orostachys fimbriatus plants such as (Orostachys fimbriatus), separation and purification and obtain scape ketose acid anhydride, obtain to have active compound, called after Isopropylidene Sedoheptulosan (Helotylphin) here with this scape ketose anhydridization compound and acetone one step condensation again.Synthetic this new active compound mainly comprises following operation steps.
1, pulverizes dry Crassulaceae plant herb, with the boiling water leaching, generally leach twice earlier, merge leaching liquid;
2, leaching liquid earlier through thin film concentration, thereafter again be evaporated to concentrate after volume be about 1/5th of former leaching liquid volume.The ethanol constant volume that adds equivalent is about about 50% alcoholic degree, places;
3, get supernatant liquor, by strong-acid type cation exchange fat post, handle by the strong basic type anion-exchange resin post more earlier;
4, effluent liquid steams and removes ethanol, and reclaims ethanol, obtains medicinal extract;
5, medicinal extract with diatomite and acidic alumina spice after, last alumina column with ethanol elution, obtains scape ketose acid anhydride;
6, the ketose acid anhydride of finding a view in the presence of an amount of sulfuric acid, adds acetone one and goes on foot condensation and obtain Isopropylidene Sedoheptulosan;
7, make preparation with usual method.
This antiviral activity chemical combination Isopropylidene Sedoheptulosan that obtains as stated above.With modern spectral methods such as chemical reaction, infrared, nucleus magnetic resonance and mass spectrums, the structure of this compound is identified qualification result is as follows:

Through the ownership of chemical reaction and spectral data, and with known allied compound relatively, the structural formula of this active compound is decided to be:
Chemistry isopropylidene scape ketose acid anhydride (Isopropylidene Sedoheptulosan) by name, this compound can be used as the preparation of anti-duck hepatitis B virus of preparation and two-way immune new drug.
For the result of treatment of proof the present invention, in duck hepatitis B virus infection duck body, carry out the result of treatment test both at home and abroad with the animal experimental model of recognizing altogether at present to duck hepatitis B virus.An age in days Beijing duck intravenous injection duck hepatitis B virus is adopted in experiment, begin after seven days to duck abdominal injection injection liquid of the present invention, one day twice, administration 10 days (Bid * 10) or 14 days (Bid * 14) is observed medicine to toxicity of duck and the influence of duck serum duck hepatitis B virus DNA (DHBV-DNA).Experimental result shows, 200,100 and 50mg/kg dosage group, one day secondary, 10 days or 14 days, equal nontoxicity, two dosage groups of 200mg/kg and 100mg/kg all can reduce DHBA infected duck serum DHBR-DNA level, do statistical study in groups relatively, administration the 7th day (T7) or the 14th day (T with the virus control group
14) DHBV-DNA has significance to reduce, 50mg/kg dosage group, significant difference does not appear in the experiment, show that injection liquid of the present invention has restraining effect to duck serum DHBV-DNA, simultaneously, experimental result also shows, injection liquid of the present invention, under this experiment condition, its 200mg/kg and 100mg/kg group are the effective dose of treatment duck hepatitis B virus.
Further observed the immunoregulatory activity of injection of the present invention to body with kunming mice.In vivo test of the present invention has tangible enhancement (P＜0.01) to Turnover of Mouse Peritoneal Macrophages lysosomal enzyme-acid phosphatase (ACP) activity.The activity of cell membrane enzyme-alkaline phosphatase (AKP) has tangible immunoregulation effect.To tumour ring necrosis factor (TNF) activity, tangible enhancement (P＜0.01) is also arranged, experiment in vitro shows that the present invention and CONA and LPS share, can strengthen the two silk, split former effect, promote lymphocyte transformation, both have share synergy (the P value is respectively＜0.01 and＜0.05), and therefore, injection liquid of the present invention is biological response modifier (Biological Response Modifer, BRM) immunomodulator in and/or immunostimulant have two-way immunologic function.
With a concrete instance the present invention is extracted scape ketose acid anhydride in the Crassulaceae plant more below, further the method for synthetic Isopropylidene Sedoheptulosan is further described.
Get eight treasures (choice ingredients of certain special dishes) (or Orostachys fimbriatus, long medicine eight treasures (choice ingredients of certain special dishes) (50kg, be ground into meal, added water boil 1 hour, emit leaching liquid after, added water boil again 1 hour, merging leaching liquid twice, earlier through thin film concentration, is about 1/5th of former leaching liquid volume through being evaporated to liquid volume again, the 95% ethanol constant volume that adds equivalent, determining alcohol is about about 50%, places, get supernatant liquor earlier by strongly-acid H
+The exchange of type cation exchange resin column, effluent liquid are again by strong basicity OH
-The exchange of type anion-exchange resin column.Effluent liquid steams ethanol, and reclaims ethanol usefulness again, makes medicinal extract.Gained medicinal extract with diatomite and acidic alumina spice after, last alumina column, with ethanol elution, can get scape ketose acid anhydride about 50 the gram.
Get above scape ketose acid anhydride 4 grams, add 80 milliliters in acetone, add an amount of sulfuric acid, induction stirring was placed after 24 hours, promptly had Isopropylidene Sedoheptulosan needle crystal to separate out, and reclaimed acetone, got product 4.1 grams, and yield is greater than 85%.
After quality test is qualified, under aseptic condition, be sub-packed in the penicillin peace bottle of 10ml capacity, every 100mg 105 ℃ of thermal sterilizations 20 minutes, promptly gets the Isopropylidene Sedoheptulosan injection.
During use, after facing with before adding about 5 milliliters of sterilizeds water for injection, making dissolving, intravenous drip, 200-300mg on the one.
The present invention extracts scape ketose acid anhydride from Crassulaceae plant eight treasures (choice ingredients of certain special dishes) or long medicine eight treasures (choice ingredients of certain special dishes) in the herb of plants such as Orostachys fimbriatus, the resynthesis Isopropylidene Sedoheptulosan has significant antiviral activity and two-way immunologic function through this new compound of experiment confirm to hepatitis B virus.Can be used as the bidirectional immune regulator of diseases such as treatment hepatitis B.
