Description

A kind of antivirus andrographolide derivative and its preparation method and application
Technical field
The invention belongs to field of heterocyclic compound, particularly to a kind of Novel antiviral andrographolide derivative and system thereof Preparation Method and application.
Background technology
Andrographolide system extracts the diterpene ginkgolide obtained in acanthaceous plant Herba Andrographis, is Chinese medicine punching One of principle active component of lotus, has the function such as heat-clearing and toxic substances removing, removing heat from blood detumescence.
Andrographolide is oral can cause vomiting because of bitter pole.Gastral cavilty can be caused when these product and several formulations are administered orally larger dose Uncomfortable, loss of appetite.Once the report of drug eruption, upper abdominal pain and anaphylactic shock was caused after having CHUANXINLIAN ZHUSHEYE intramuscular injection.Instead Should acutely person's symptom visible: uncomfortable in chest, out of breath, pale complexion, cyanotic lips, be in a cold sweat, pulse is thin and delicate, blood pressure drops etc.;Reaction The lighter normally behaves as stomachache, vomiting, asthma, urticaria, pimple, dizziness, feeling of fullness in the head, sneeze etc..Occur that the time of reaction has i.e. Time, also there is appearance in 5~20 minutes after injection, after rescuing, typically gradually took a turn for the better in 5~45 minutes, individual other warp Within 24 hours, begin to recover.Also have and cause the report of acute amniotic fluid blocking person with the exchange induced labor of Herba Andrographis amniotic fluid.
For improving clinical efficacy, after general extraction andrographolide, prepare the injection of various soluble derivative, such as Asia Sodium bisulfate addition product, sodium sulfonate addition product and succinic acid half-ester monopotassium salt etc..Wherein sodium sulfite addition andrographolide The national drug standards have been taken in andrographolide succinic acid half-ester monopotassium salt (Potassium DehydroandrograpolidSuccinate Succinate for Injection).The most clinical conventional wearing Heart lotus lactone succinic acid half-ester monopotassium salt also known as Andrographolide, the numerous studies that more than 30 years are clinical, it was demonstrated that its have the most antipyretic, Antiinflammatory, promotion adrenal cortex function and sedation, can promote the phagocytic activity of neutrophilic granulocyte macrophage, improves serum The content of middle lysozyme.Research is thought, andrographolide compound so that inflammation in early days capillary permeability is increased and oozes out, Edema inhibitory action is notable, and prompting andrographolide compounds is the non-specific anti-inflammatory of a kind of new type.Andrographolide Wide clinical application in infantile pneumonia, viral upper respiratory tract infection, tracheitis, influenza, leptospirosis and acute carefully Bacterium property dysentery etc. are wherein the most notable with antipyretic response.
But it is, above-mentioned that oneself knows that medicine dissolubility in water is the most undesirable.Modern pharmacological research shows, andrographolide and Derivant such as dehydrorographolide, 14-deshydroxy-11,12-two dehydrogenation andrographolide-3,19-disuccinic acid half ester list potassium Salt, Andrographolide, 14-deshydroxy-11,12-two dehydrogenation andrographolide-3,19-disuccinic acid half ester k-na salt (andrographolide), Andrographolide sulfonate (Xiyanping), Adduct of andrograp (Lian Bizhi) etc. can suppress blood capillary in early days Pipe permeability increases and inflammatory exudation and edema, specifically excited Pituitary Adrenalcortical function, promotes ACTH release, increases Add the biosynthesis of ACTH in antepituitary;There are antiphlogistic antibacterial, inactivated adenovirus, influenza virus, Respirovirus etc. multiple The effect of virus, is widely used in treatment infantile pneumonia clinically, upper respiratory tract infection (1, Liu Xinjian, Wang Yifei, Li Gui Raw.Pharmacological research progress (J) of andrographolide and derivant thereof, Chinese crude drug, 2003,26:135-138;2, Dai Guifu, Wang Jun Peak, He Shuaiwei, etc..Pharmacology activity research progress (J) of andrographolide and derivant thereof, Chinese patent medicine, 2006,28 (7): 1032-1035。)
Andrographolide, dehydrorographolide and 14-deshydroxy-11,12-bis-dehydrogenation andrographolide-3,19-bis-amber The structure of amber acid half ester is as follows:
Andrographolide dehydrorographolide 14-deshydroxy-11, in 12-bis-dehydrogenation Herba Andrographis
Ester-3,19-disuccinic acid half ester.

Embodiment 2
The present embodiment is the preferred version on the basis of embodiment 1, and the present embodiment is andrographolide three succinic acid half-ester Preparation with andrographolide three succinic acid half-ester glycinate.
Described preparation method is: by andrographolide 40g (0.12mol), succinic anhydrides 40g (0. 40mol), sulfurous acid Sodium 4.0g, is placed in reaction bulb, mixing, sets up reflux and drying tube, begins to warm up, and regulation vacuum is 520 ~ 620 mm Hg, 100 DEG C, back flow reaction 5 hours, evacuation after cooling.Add 800ml water in reaction bulb, be stirred well to all solidify Till evacuating with crystallize.Sucking filtration, is dried the filter cake normal-temperature vacuum obtained, and dried filter cake is added sodium bicarbonate aqueous solution molten Solve, filter to get filtrate, use the hydrochloric acid of 0.1 ~ 12mol/L to adjust the pH to 4 of filtrate, separate out white precipitate, sucking filtration, be dried to obtain and wear Heart lotus lactone three succinic acid half-ester.
Utilize andrographolide three succinic acid half-ester obtained above, prepare andrographolide three succinic acid half-ester glycine Ester.
Described preparation method is: takes andrographolide three succinic acid half-ester, adds methylene chloride and make dissolving, adds the sweet of excess Propylhomoserin, is simultaneously introduced DCC, is heated to reflux 1 ~ 2 hour, and thin layer follows the tracks of reaction, cold rear filtration, vacuum drying, andrographolide three Succinic acid half-ester glycinate, total recovery is 70 ~ 80%.
Andrographolide three succinic acid half-ester glycinate, pale yellow powder, odorless, bitter in the mouth.Soluble in water, it is slightly soluble in dilute Ethanol, insoluble in chloroform or ether.Andrographolide three succinic acid half-ester and andrographolide three succinic acid half-ester salt pharmacodynamics Research shows that its antipyretic response is significantly larger than Andrographolide.
Investigate effective dose and the pharmacological action of described andrographolide three succinic acid half-ester glycinate, for clinical practice Foundation is provided.Method: Ovum Gallus domesticus album causes rat paw edema, rat granuloma is swollen and mice caused by dimethylbenzene xylene peritonitis model observes punching The antiinflammatory action of lotus lactone three succinic acid half-ester glycinate;Dry yeast cause rat fever, dinitrophenol,DNP cause rat fever and Endotoxin causes rabbit fever models and observes the refrigeration function of andrographolide three succinic acid half-ester glycinate;Tube propagation method is seen Examine the antibacterial action of andrographolide three succinic acid half-ester glycinate.
Result: andrographolide three succinic acid half-ester glycinate dose-effect relationship is obvious: 300mg/kg and 150mg/kg pair Rat fever caused by dry yeast and dinitrophenol,DNP and the fever in rabbits caused by endotoxin all have good refrigeration function, 75mg/kg is to three kinds of heating functioins the most inconspicuous (seeing table 1, table 2, table 3).400mg/kg and 200mg/kg is to caused by Ovum Gallus domesticus album Rat paw edema, rat granuloma be swollen and mouse peritoneum inflammation caused by dimethylbenzene all has a good antiinflammatory action, 100mg/kg pair Three kinds of inflammatory effect the most inconspicuous (seeing table 4, table 5, table 6).
Seeing table 7, the MCI of andrographolide three succinic acid half-ester glycinate escherichia coli and dysentery bacterium is 2mg/kg It is 1mg/kg conclusion to gold-coloured staphylococci and pneumococcal MCI: andrographolide three succinic acid half-ester glycinate has relatively Good antipyretic and antiinflammatory action, but its antibacterial action is more weak.
Horse lotus ester tripotassium salt is basically identical with andrographolide three succinic acid half-ester glycinate results of pharmacodynamic test.
