Description

Radix Wikstroemae extract of anti-AIDS and preparation method thereof, medicine and purposes
The present invention relates to medical technical field, exactly it is Radix Wikstroemae extract of anti-AIDS (AIDS) and preparation method thereof, medicine and purposes.
Radix Wikstroemae (Wikstroemia indica) is a Thymelaeceae Flos Wikstroemiae Dolichanthae platymiscium, is born in the shrubbery of the foot of the hill and hillside humidity, mainly is distributed in ground such as Guangdong, Guangxi, Fujian, Taiwan, Zhejiang, Jiangxi, Hunan, Sichuan.This stem leaves of plants, root and fruit all can be used as medicine, and have the effect of heat-clearing and toxic substances removing, dispersing swelling and dissipating binds, pain relieving, control carbuncle, rheumatalgia, traumatic injury [the new medical college in Jiangsu is compiled Chinese medicine voluminous dictionary (1977, the Shanghai People's Press), pp.51-53].Among the people, normal and other Chinese herbal medicine compatibilities of Radix Wikstroemae are widely used in kinds of tumors [Wang Bing chief editor, Chinese medicine medicine for preventing Fang Xuan (1992, the People's Medical Officer Press), pp.16-17] such as treatment pulmonary carcinoma, cervical cancer, breast carcinoma, lymphatic cancer.Yet up to now, research to Radix Wikstroemae is less, be more common in the chemical constituent report, the rarely seen inhibition of activity research mice body endolymph cancer p-338 tumor strain effect [Katoet al., J.Nat.Prod., 1979,42:159-162] and PKC enzyme inhibition [Ko eta1., Biochem.J., 1993,295:321-327; Wangetal., Euro.J.Pharm., 1995,288:341-348; Chen et al., Biochem.Pharm., 1996,52:1025-1032].In addition, do not see any report about anti-AIDS (AIDS) or HIV (human immunodeficiency virus) HIV-1 and HIV-2.Acquired immune deficiency syndrome (AIDS) is the very high and extremely refractory disease of a kind of infectiousness, also finds no the report of the higher medicine of cure rate at present both at home and abroad.The inventor is upon the look in medical herbs anti-AIDS (AIDS) the active component process, found that brother's five extracts have good anti-AIDS (AIDS) activity, and therefrom obtained a plurality of chemical compounds with multiple framework types such as the active dicoumarol of anti-AIDS (AIDS), lignanoid, flavone, flavonoid glycoside and bisflavones.
The objective of the invention is to systematically study anti-AIDS (AIDS) active component of Radix Wikstroemae, searching obtains the new purposes of anti-AIDS (AIDS) effective site exploitation Radix Wikstroemae anti-AIDS (AIDS), a kind of anti-AIDS new drug Radix Wikstroemae extract is provided, and simple and practical process route is provided.
The present invention is achieved in that herb, root, stem and leaf or the fruit with Radix Wikstroemae (Wikstroemia indica) is raw material, adopt solvent extraction method, solvent extraction, resin adsorption method, polyamide adsorpting column chromatography method, one or more technologies in the technologies such as normal phase column chromatography, reversed-phase column chromatography, and be prepared into Radix Wikstroemae extract in conjunction with conventional drying method such as concentrate drying, lyophilization, spray dryinges.With the Radix Wikstroemae extract made as AIDS resisting (AIDS) active component, make it to combine and make dosage forms such as powder, granule, tablet, capsule, pill, suppository, enteric agents, injection, syrup, Emulsion, suspensoid, tincture, unguentum, spray, be used for the treatment of and comprise by HIV-1 and HIV-2 virus and other viral AIDS that causes (AIDS) and various complication thereof according to conventional method with suitable excipient.
Plant material Radix Wikstroemae (Wikstroemia indica) can be a herb, also can be root, stem and leaf or fruit.Raw material can be fresh collection, also can be through concocting.
The chemical compound that comprises wherein contained various types of coumarins, dicoumarol, lignanoid, flavone, flavonoid glycoside, bisflavone and other framework types as the Radix Wikstroemae extract of AIDS resisting (AIDS) active component.
In the solvent extraction method that is adopted, a kind of solvent in optional water, methanol, ethanol or other lower aliphatic alcohols, the also mixed solvent that can be formed with arbitrary proportion with any two or more solvents wherein, at room temperature soak into extraction or, perhaps under heated condition, soak into extraction or reflux, extract, with supersonic oscillations instrument supersound extract.Extraction time can be once also can be repeatedly.
In the solvent extraction that is adopted, a kind of solvent in water or lower aliphatic alcohols or mixed solvent can be extracted and the extract mixture through being obtained is suspended from the water, directly extract with in ethyl acetate, n-butyl alcohol, aquifer ethyl or the moisture n-butyl alcohol one or more.Perhaps after low polarity solvent (as petroleum ether) defat, one or more in reuse ethyl acetate, n-butyl alcohol, aquifer ethyl or the moisture n-butyl alcohol extract.Extraction times can be once also can be repeatedly.
In the resin adsorption method that is adopted, resin can be selected the adsorbent resin of D-101 type adsorbent resin, XAD-2 type adsorbent resin, CHP-20P adsorbent resin and other types for use, one or more in eluting solvent methanol, ethanol, acetone, aqueous methanol, aquiferous ethanol or the aqueous acetone.Can the isoconcentration eluting during eluting, also can gradient elution.
The eluting solvent is with methanol or aqueous acetone in the polyamide adsorpting column chromatography method that is adopted.Can the isoconcentration eluting during eluting, also can gradient elution.
In the normal phase column chromatography that is adopted, can select normal pressure or pressurized silica gel column chromatography for use, the optional column chromatography silica gel of used column packing, perhaps thin layer chromatography silica gel, eluant can be selected one or more in benzene/acetone, dichloromethane/acetone, chloroform/acetone, methylene chloride, chloroform/methanol, ethyl acetate/methanol, benzene/acetone, dichloromethane/acetone, chloroform/acetone, methylene chloride/water, chloroform/methanol or the ethyl acetate/methanol/water etc. for use.Can the isoconcentration eluting during eluting, also can gradient elution.
The reversed-phase column chromatography that is adopted can be selected normal pressure or pressurization reversed phase column chromatography for use, the optional octadecyl bonding of used column packing phase (ODS) or eight alkyl linked phases, and eluant is with aqueous methanol or contain water-acetonitrile.Can the isoconcentration eluting during eluting, also can gradient elution.
The drying means that is adopted comprises conventional drying method such as concentrate drying, lyophilization, spray drying.
As AIDS resisting (AIDS) active component, the consumption of Radix Wikstroemae extract is adult 1~1000mg every day, preferred 30~800mg/ days, takes every day 2~3 times.
Oral administration can be made into common formulations such as tablet, powder, granule, capsule, needs a kind of excipient at least, as starch, lactose, sucrose, mannose, hydroxy methocel etc., but tablet coating also.Except that these excipient, also can use magnesium stearate, sodium laurylsulfate, Pulvis Talci etc. as lubricant, dextrin, crystalline cellulose, polyvinylpyrrolidone, arabic gum, corn starch, gelatin etc. are as binding agent, and potato starch, hydroxy methocel are as disintegrating agent.In addition, also can be made into syrup, Emulsion, suspensoid etc.For these dosage forms, can add correctives, flavoring agent or coloring agent etc.
Exterior-applied formulation comprises suppository, ointment, external pulvis, spray, enema, Emulsion or the like.Here employed solid or liquid additive are often using in the art.For ointment, select the additive of the hydrophobic base formed by water, fat, fatty oil, lanoline, vaseline, glycerol, Cera Flava, paraffin, liquid paraffin, resin, higher alcohol, plastics, surfactant or hydrophilic matrix (comprising Emulsion substrate, water-soluble base suspended substrate) etc. for use.
When making injection, generally use distilled water for injection, normal saline, D/W, injection vegetable oil, propylene glycol, Polyethylene Glycol etc.In case of necessity, also can add suitable isotonic agent, cosolvent, antioxidant, antiseptic etc.
