This invention also describes the three noval compounds, and their pharmaceutically acceptable salts, and their prepn. methods, where: X1, X2, R1, R2, (R3), (R6), (R7), (R9), (R11), R4, R5, R8, R10, R12 are illustrated as specification of this invention.
Description
Technical field
The present invention relates to be used for the treatment of the new compound of cancer and broad-spectrum antimicrobial--morellic acid, neogambogic acid, allogambogic acid series derivates and preparation method thereof.
Background technology
Gamboge is guttiferae plant gamboge tree excretory dry resin, and is cold in nature, and it is sour, hot, puckery, poisonous to distinguish the flavor of, and the successive dynasties are that cream, ball, the powder of main component has multiple with the gamboge.Gamboge is recorded by American Pharmacopeia, and its activeconstituents is mainly morellic acid (comprising a spot of neogambogic acid and allogambogic acid).General chemotherapy anticarcinogen also influences normal hemopoietic system and white corpuscle in kill cancer cell.And morellic acid is when using as cancer therapy drug, and it is kill cancer cell optionally, can not influence normal hemopoietic system and white corpuscle.Therefore, total cambogic acid is used as anticancer chemicals, compares with anticancer chemicals commonly used in the market to have extraordinary advantage.
" Jiangxi Medical College's journal " 1980 (1), 17,1981 (1) 13 report morellic acids are to sarcoma (S
180) and ehrlich carcinoma restraining effect is arranged." Jiangxi Medical College's journal " 1983 (3), 5 be the morellic acid extraction using alcohol, and the total ethanol extract that obtains reclaims ethanol, uses the boric acid water dissolution, and add the tween 80 solubility promoter and make injection, and this injection is carried out relevant toxicity research.
" Tianjin medicine oncology supplement " 1981,8,230 reports are made injection liquid with morellic acid and are used for clinical treatment 50 routine malignant tumours.Present report mainly is that the general extractive with gamboge is dissolved in the physiological saline and uses.According to " Jiangxi medicine ": the clinical use of gamboge has local irritant effect to blood vessel, and is too fast when instiling, concentration is high slightly or administration time when longer, can cause superficial phlebitis; Soup leaks into outside the blood vessel during injection, can cause local swelling and pain.Though so total cambogic acid has the advantage of selectively killing cancer cells as anticancer chemicals, it is bigger yet to exist toxicity.Use inconvenience and bring the problem of side effect.
The patent of China Medicine University " mixture of gambogic acid compounds with anticancer activity and preparation method thereof ", and publication number: CN1309125A (application number: 01108049.3), 2001/01/17.It is with gambogic acid compounds and different base or ion formation mixtures, mainly make morellic acid and amino acid form water miscible mixture, and be that effective constituent has been made anticancer chemical drug respectively with this mixture, powder injection, complex tablet, complex capsule, emulsion etc. are arranged.Thereby improved drug effect, reduced pungency and toxicity.This patent is that morellic acid is laid a good foundation as a kind of good promoting the use of of PTS.Morellic acid is planted as pure natural and is carried cancer therapy drug, and it has obtained very big success.
Morellic acid is orange-yellow crystalline powder, solubleness is bigger in organic solvents such as alcohols, ketone, but in water, can not dissolve, though in highly basic (as sodium hydroxide solution), can dissolve, but the morellic acid in the alkaline solution is extremely unstable, is easy to hydrolysis, and patent CN1309125A selects compound L-arginine for use, solved water-soluble problem, but stability also not very high.Simultaneously, though patent CN1309125A has improved the anticancer drug effect of morellic acid, compare with cancer therapy drug such as camptothecine or slightly inferior.
Summary of the invention
The purpose of this patent is exactly under the prerequisite of the main framing that keeps total cambogic acid (comprising morellic acid, neogambogic acid, allogambogic acid) structure, its group is modified, so that when using, compare with total cambogic acid and to have as the effective constituent of new cancer therapy drug and broad-spectrum antimicrobial:
(1) higher stability.
(2) better solvability, better at the partition ratio of fat phase and aqueous phase.
(3) better drug effect.
(4) smaller toxic side effect.
Nineteen fifty-five Amorosa obtains highly purified morellic acid first through the pyridinium salt crystallization, and nineteen sixty-five has been determined the molecular structure of morellic acid by nucleus magnetic resonance, and the report document of morellic acid preparation is more.We select for use following method to prepare highly purified total cambogic acid (HPLC＞97%) at this:
(1) select a kind of organic solvent for use: acetone or methyl alcohol or pyridine etc. are molten to be got and crystallization obtains the crude product of morellic acid pyridinium salt.
(2) with behind the ether-sherwood oil recrystallization three times, obtain purified morellic acid pyridinium salt.
(3) thus this salt obtains highly purified morellic acid with hydrochloric acid flush away pyridine in organic solvents such as ether.
This morellic acid is obtained morellic acid, neogambogic acid, allogambogic acid through the high performance column separation.Structural formula is as follows respectively:
