Abstract

Levo- and dextro-chloro-skuliline are prepared by synthesis process and belong to tetrahydroberberine compound with stronger medicinal action.

Description

Left and right chlorine Si Kuli quinoline and their purposes of revolving
The present invention relates to organic synthesis.
L-spd [(-)-stepholidine, (-)-SPD] [I] and rotundin [(-)-tetrahydropalmatine, (-)-THP] [II] 12-chloro Si Kuli quinoline [2,9-dihydroxyl 3,10-dimethoxy-12-chloro-tetrahydrochysene berbine, THPB-18] [III], their structure is very similar, through Shanghai Pharmaceutical Inst., Chinese Academy of Sciences at first confirm they be in the brain of novel type Dopamine HCL (Dopamine, DA) receptor-blocking agent have extensive potential applicability in clinical practice.
L-spd and hyndarin are Tetrahydro-proto-berberines congener (tetrahydroprotoberberines, THPBs), rotundin is a kind of neuroleptanalgesic, loaded China pharmacopeia, left-handed stephanine clinical application is in treatment hyperkinetic syndrome and migraine, and can be used for psychotic treatment.L-spd is to separate to obtain from the piece root of Root of Japanese Stephania plant, but because plant resources sharply descends, clinical use has hidden danger, because l-spd carries out large-scale commercial production with synthetic method very big difficulty is also arranged, be necessary that therefore the congener of seeking other substitutes l-spd again.
Control the racemize of reporting with golden Tian Chongfu 2 by Japanese scientist tortoise paddy wise man, synthetic (the pharmaceutical journal 87 of 9-dihydroxyl-3-10-dimethoxy-12-chloro-tetrahydrochysene berbine, 1070 (1967)] nineteen sixty-eight is recorded in chemical abstracts, compound number is [17891-0-0-8], it is that reaction makes through 11 steps as starting raw material with isovanillin, but up to making the report of not seeing about its biological effect.
The present invention seeks to seek a kind of Tetrahydro-proto-berberines congener, it not only can be made the interior novel retarding agent of Dopamine Receptors of brain but also meets the industrial production condition.
The present invention finishes through the following steps.
Make 1 (Ber.96,1520[1962]) by isovanillin through two step reactions.
Figure A9411223500051
Compound 1 sulfuryl chloride chlorination; obtain 2-chloro-4-methoxyl group-5-hydroxyl phenylacetic acid (2); compound 2 usefulness iodate 1-methyl-2-bromopyridines make activator and 3-methoxyl group-4-benzyloxy phenylethylamine 3 is condensed into acid amides 4; also can be by compound 2 and 3 directly dehydration generation 4 at high temperature; the hydroxyl of compound 4 generates 5a respectively with isobutyl oxygen formyl radical or ethanoyl protection; 5b; 5a; 5b is transformed into dihydro-isoquinoline salt 6a with the Bischler-Napieralski method respectively with Phosphorus Oxychloride; 6b; in ethanol or methyl alcohol, reduce and the deacylated tRNA base with boron hydrogen sodium then; obtain tetrahydroisoquinoline 7; 7 at room temperature carry out the Mannich reaction with formaldehyde; obtain racemize 2-benzyloxy-3,10-dimethoxy-9-hydroxyl-12-chloro-tetrahydrochysene berbine (8).Compound 8 is used the hydrochloric acid debenzylation in formic acid, obtain racemize 2,9-dihydroxyl-3,10-dimethoxy-12-chloro-tetrahydrochysene berbine (III) (±-THPB-18).
Compound 8 usefulness optical activity dibenzoyl tartaric acids split into left-handed and dextral compound 8 as resolving agent, levorotatory compound 8 and dextrorotatory compound 8 obtain the levorotatory compound III with the hydrochloric acid debenzylation respectively in formic acid and the dextrorotatory compound III is (-)-THPB-18 and two compounds of (+)-THPB-18.
The chemical property of (-)-THPB-18 compound;
The chiral carbon of (-)-THPB-18 is C14, and specific rotation is [α] D 11.5=-223.19 ° of (CHCl 3, C=0.14), fusing point 161-162 ℃ (decomposition), C 2And C 9The position has hydroxyl, C 3And C 10The position has methoxyl group; The face look is a dark brown red, is dissolved in dilute sulphuric acid and methyl alcohol, organic solvents such as chloroform, silica gel thin-layer chromatography, (solvent systems is an ethyl acetate), R rBe worth consistent with (±)-THPB-18.

The specific rotation of (+)-THPB-18 [α] D 11.5+ 222.53 ° of (CHCl 3, C=0.12), other physico-chemical properties are identical with (-)-THPB-18 in addition, calculated value: C, 63.07 H, 5.57 N, 3.87 Cl, 9.80, measured value: C, 62.83, H, 5.72 N, 3.62Cl9.99.
Method of the present invention is that raw material reacts synthetic racemize 2 through 9 steps with the isovanillin, 9-dihydroxyl-3, and 10-dimethoxy-12-chloro-tetrahydrochysene berbine, more easier than the method in Gui Gu and golden field.
(-)-THPB-18, (+)-THPB-18, (±)-THPB-18 and (-)-SPD compare the avidity of DA receptors bind:
Use D 1And D 2Two kinds of DA receptor binding assays, prove (-)-THPB-18 and (±)-THPB-18 be to D 1And D 2Look and power [Ki] all on the nM level, wherein (-)-THPB-18 is to D 1And D 2Effect stronger slightly than (±)-THPB-18, yet (-)-THPB-18 and (±)-THPB-18 are to D 1Effect than (+)-THPB-18 15-25 eager to excel in whatever one does doubly, they are to D 2Effect than the strong 953-1605 of (+)-THPB-18 doubly.(-)-TBPB-18 is to D 1Effect and (-) SPD similar.Yet the former is to D 2Effect stronger approximately 14 times than (-)-SPD, show thus (-)-effect of THPB-18 is stronger than (-)-SPD.
Table 1 THPB-18 optically active isomer and (-) SPD are right
The comparison radioreceptor of DA receptor acting avidity is in conjunction with test (-)-SPD (-)-TBPB-18 (±) THPB-18 (+)-THPB-18[ 2H] S △ H28890 D1 Ki (mM) 8.6 5.7 8.9 135[ 2H]-Spipeane D2 Ki (mM) 80.0 6.7 9.6 9150
D 2/ D 1Ratio 91 1.07 67 (-)-THPB-18 is to the pharmacodynamics test (table 2) of DA acceptor retardation: from suppressing the minimizing of spontaneous activity in mice, the antagonism amphetamine to mouse excitation activity and antagonism Apomorphinum to typing active action of mouse etc., the test of three DA nervous system activities shows that (-)-THPB-18 has retardation to DA acceptor in the brain, the effect of antagonism presynaptic and postsynaptic DA receptor simultaneously, action intensity is similar to (-) SPD or strong slightly.
By the DA neurone discharge activities test of record black substance dense area (SNC), prove (-)-THPB-18 can antagonism D 2And D 1The effect of receptor stimulant, show (-)-THPB-18 has the action characteristic of DA receptor-blocking agent stronger slightly than the effect of (-)-SPD.
Rat circling behavior and GTP regulate D 1The test of acceptor high-affinity demonstrates (-)-THPB-18 to D 1Acceptor has agonism, and this action characteristic is identical with (-) SPD.In the DA receptor-blocking agent, have D concurrently 1The compound of receptor agonism has only (-)-SPD at present, and this agonism may be to weaken the cataleptic major reason of (-)-SPD, becomes (-)-big characteristics of SPD effect.Similarly, (-)-THPB-18 also has such action characteristic.
According to the chemical structure of (-)-THPB-18 and similarity inference (-)-THPB of pharmacological action feature and (-)-SPD, the clinical application of (±)-THPB has the indication similar to (-) SPD probably.
