Description
Technical field
The present invention relates to 24 (R)-pseudo-ginsenoside-GQ and semisynthesis thereof and its application in preparation treatment myocardial ischemia, ischemic shock, arrhythmia and reperfusion injury and cancer therapy drug.
Background technology
After the main effective constituent, chemists are devoted to the conversion of the synthetic and effective monomer of some monomer saponin in ginsenoside is proved conclusively to genseng and Radix Panacis Quinquefolii.At present, mainly contain following several method in research and using, for example acid-hydrolysis method, alkali hydrolysis method, enzymolysis process, condensation method etc.First three methods mainly is between total saponins and monomer saponin, falls in the molecule certain part or several parts by hydrolysis and realizes that a certain monomer saponin or several monomer saponin are after transforming; The back is a kind of then to obtain a certain monomeric compound with aglycon by becoming the glycosides reaction by sugar.
Nineteen eighty-two, Hart B H reported first with under the gentle sour condition, make ginsenoside degraded and measured the structure of degraded product.For example, with ginsenoside-Rg1, use 0.1M HCl, under 37 ℃ of conditions with without handling pitch time, obtain the degraded product ginsenoside Rh1, Li Pingya, prepare the monomer ginsenoside Rg3 (patent No.: ZL98103433.0) Deng having studied through acid hydrolysis from ginsenoside glycol group, Chen Yingjie waits first and finds, under suitable reaction conditions, the alkali catalyzed hydrolysis method, to ginsenoside degraded have reaction temperature and, advantage such as control is successfully synthesized ginsenoside Rh1 from the ginsenoside Rg2 with this method easily.Song Changchun in 1992 etc. use with quadrat method and have prepared monomer ginsenoside Rh1 and Rh2 from the stem and leaf of Radix Panacis Quinquefolii saponin(e.Also have some with the acid-base method degraded, with the example of enzymic degradation, repeat no more.Li Pingya waits and has reported that relevant oxidation, the cyclization method of utilizing makes ginsenoside Rg3 change into pseudo-ginsenoside-Pgq (patent No.: ZL 0012837.9).
Do not see the synthetic method of relevant 24 (R)-pseudo-ginsenoside-GQ and the report of compound at present, this compound belongs to new compound, belongs to synthetic first; The new pharmaceutical use of this compound belongs to first to be found.
Summary of the invention
The object of the present invention is to provide a kind of compound: 24 (R)-pseudo-ginsenoside-GQ:
Its chemical name is: 3-O-[β-D-Glucopyranose-(1-2)-β-D-glucopyranosyl]-Da Ma-20S, 24R-epoxy-3 β, 12 β, the 25-triol (3-O-[β-D-glucopyranosyl-(1-2)-β-D-glucopyranosyl]-dammar-20S, 24R-epoxy-3 β, 12 β, 25-triol).Mp:231.7 ℃～232.2 ℃, white powder is soluble in methyl alcohol, ethanol, propylene glycol etc.Because of this compound is a new compound, be to obtain through semisynthesis with the protopanoxadiol saponin(e, its constitutional features C17 position has similar residue to pseudo-ginsenoside F 11, difference is that the C-24 position is configured as the R type, it also is one of endemic element in the Radix Panacis Quinquefolii, so called after 24 (R)-pseudo-ginsenoside-GQ is called for short 24 (R)-PGQ (P: intend; G: genseng; Q: Radix Panacis Quinquefolii: promptly change into the compound with Radix Panacis Quinquefolii constitutional features by the protopanoxadiol saponin(e, the C-24 position is configured as the R type).
The present invention also aims to utilize 20 (S)-ginsenoside Rg3s is precursor, through organic chemistry synthetic methods such as peroxidation, cyclisation, prepares a kind of novel substance that has than strong biological activity.
For achieving the above object, invent the semisynthesis of taking is:

The application of the present invention 24 (R)-pseudo-ginsenoside-GQ in preparation treatment coronary heart disease, myocardial ischemia, ischemic shock, arrhythmia and reperfusion injury and cancer therapy drug.
When the present invention is used for preparation treatment coronary heart disease, myocardial ischemia, ischemic shock, when arrhythmia and reperfusion injury and anticancer medicine, its oral or parenteral admin, all be safe, under oral situation, it can any conventionally form administration, as powder, granula, tablet, capsule, pill, solution, suspension, syrup, buccal tablets, sublingual lozenge etc.: when this medicine administered parenterally, can take any conventionally form, for example injection: as intravenous injection, ointment, suppository, percutaneous dosing, inhalation etc.
It is to be made of effective constituent monomer or the effective constituent vehicle with solid or liquid that the present invention prepares treatment coronary heart disease, myocardial ischemia, ischemic shock, arrhythmia and reperfusion injury and anticancer medicine, the vehicle of solid used herein or liquid is well known in the art, lift several object lessons below, powder is the powder agent that takes orally, its vehicle has lactose, starch, paste essence, lime carbonate, synthetic or puritan filler aluminium, magnesium oxide, Magnesium Stearate, sodium bicarbonate, dry yeast etc.; The vehicle of solution has water, glycerine, 1,2-propylene glycol, simple syrup, ethanol, ethylene glycol, polyoxyethylene glycol, Sorbitol Powder etc.; The vehicle of ointment can use fatty oil, and hydrous wool, Vaseline, glycerine, honeybee is cured, wood is cured, white oil, resin, senior hydrophobizing agent or the hydrophilizing agent that is combined into such as cured.
Beneficial effect of the present invention is, new compound 24 (R)-pseudo-ginsenoside-GQ can be used for preparation treatment coronary heart disease, myocardial ischemia, ischemic shock, arrhythmia and reperfusion injury and anticancer medicine, compare with precursor compound 20 (S)-ginsenoside Rg3 or with its enantiomorph pseudoginsenoside GQ, have the characteristics that are better than the two evident in efficacy.
Because of containing fat-soluble pair of key in 20 (S)-ginsenoside Rg3 side chain C24-35 positions, water-soluble relatively poor, oral administration biaavailability is low, through 24 (R)-pseudo-ginsenoside-GQ behind the structural modification, when having eliminated two key, increase by 1-OH, thereby increased water-soluble widely, improved oral administration biaavailability, biological activity obviously improves, and makes it have more into the property of medicine.
The dosage of active substance can be according to the mode of taking, and patient's age and body weight and the degree that is in a bad way change with other similar factor, and oral dose is: 8.0～16.0mg/kg, and every day, secondary was taken: injection 6.0～9.0mg/kg, once a day.
