Definitions
- the present invention relates to a hydroxy acid ester compound substituted with phenol, a preparation method and use in medicine.
- the compound can be used as a sedative hypnotic and/or anesthetic drug administered intravenously or intravenously.
- Propofol is a sedative that is currently widely used in the induction, maintenance, and intensive care of general anesthesia. Propofol has the characteristics of rapid onset and rapid metabolic inactivation. Since its first clinical report in 1977, it has been gradually promoted and applied worldwide. Since the solubility of propofol in water is only 146 mg/L, the currently clinically applied preparation is prepared from 1% propofol, 10% soybean oil, 2. 25% glycerol and 1.2% refined egg yolk lecithin. As a 0/W emulsion, this dosage form is still widely used in countries all over the world.
- disodium edetate is also added as an inhibitor of bacterial growth.
- the formulation is a white emulsion liquid, P H7.0 is slightly viscous, easy to inject, stable at room temperature, insensitive to light, and encapsulated in ampoules with nitrogen.
- this preparation still has many disadvantages.
- various stabilizers and solubilizers added are inevitably susceptible to some allergic reactions; soybean oil, lecithin, etc.
- the present invention will first provide a hydroxy acid ester compound substituted with a phenol. Based on this, the present invention further provides a process for preparing the compound, and the use of the compound in medicine.
- the hydroxy acid ester compound of the substituted phenol of the present invention has a structure as shown in the formula (I):
- Y is a linear carbon chain of c r4 , preferably the linear carbon chain Y is a saturated carbon chain, in particular, the linear carbon chain Y is -CH 2 -CH 2 - or - CH 2 -CH 2 - CH 2 - is the best.
- the linear carbon chain Y in the structure of the compound of the above formula (I) is in the form of a simple linear carbon chain, and may have at least one H on its carbon chain including a mercapto group, an ethyl group, a cyclopropyl group, A form substituted with a substituent such as a hydroxy group, a thiol group, an amino group or a substituted amino group.
- the experimental results show that the compound of the present invention having the structure of the above formula (I), as a prodrug of propofol, is configured as a pharmaceutically acceptable emulsion and the like, and enters the body intravenously, and can rapidly decompose and release the substituted phenol structure therein.
- (propofol) produces sedative, hypnotic and/or anesthetic effects, which can effectively overcome the shortcomings of the hydroxy group in the substituted phenol structure, which is stable in vitro and can be rapidly decomposed into the body.
- the hydroxy acid or the corresponding esterified product released by the compound of the formula (I) is not toxic to the human body.
- the substituted phenolic hydroxyester compound of the formula (I) of the present invention can be suitably used as a central inhibitory drug which exerts sedative, hypnotic and/or anesthetic effects on animals or humans by intravenous or extravascular routes. Function and effect. Further modifications can be obtained by further modifying the hydroxyl groups in the structure of the compound of formula (I) ⁇ ! Juice organisms, for example, bonded to water-soluble molecules, can give various water-soluble substituted phenol derivatives based on the above structures.
- the preparation of the above substituted phenolic hydroxyester compound can be carried out by using 2,6-diisopropylphenol (II) as a raw material, and reacting with the dianhydride compound (III) in the presence of a deacidifying agent and 4-diaminopyridine. Forming the diacid monoester intermediate (IV); or the 2,6-diisopropylphenol (II) and the diacid compound (III') in the condensing agent N, N-dicyclohexylcarbodiimide ( DCC) reacts with a catalytic amount of 4-diaminopyridine to form a diacid monoester intermediate (IV).
- DCC N-dicyclohexylcarbodiimide
- the diacid monoester intermediate (IV) is reacted with sodium borohydride and iodine to obtain the corresponding substituted phenol hydroxy ester compound product (I), the dianhydride compound (III) and the diacid compound ( ⁇ ) Y in the formula is a linear carbon chain of C r4 .
- the reaction process is as follows:
- Y in the diacid compound ( III ' ) or the dianhydride compound ( III ) in the reaction formula is a saturated carbon chain, and among them, preferably - CH 2 -CH 2 -or- CH plant CH plant CH 2 -.
- an organic basic compound such as pyridine or a tertiary amine compound including triethylamine can be usually selected.
- the preparation process can be generally carried out in, for example, dichloromethane, chloroform, carbon tetrachloride, chlorobenzene, benzene, toluene, petroleum ether, cyclohexane, n-hexane, acetonitrile, acetone, DMF, DMS0>tetrahydrofuran, diethyl ether. It is carried out in various organic solvents such as triethylamine or pyridine.
- diacid monoester intermediate (IV) of 2,6-diisopropylphenol In addition to the use of the dianhydride compound (III), it is also possible to make 2,6-diisopropylphenol (II) with an equimolar diacid compound (III') in an equimolar amount of N,N-dicyclohexylcarbodihydryl In the presence of an imine (DCC) condensing agent and a catalytic amount of 4-dipyridinium aminopyridine, after sufficiently reacting at TC-room temperature, the precipitate in the reactant is filtered off, and the solvent is distilled off to obtain a diacid monoester intermediate. (IV) The crude diacid monoester intermediate (IV) can be further recrystallized from cyclohexane/ethyl acetate or another suitable solvent to give the purified intermediate (IV).
- DCC imine
- V mixing the upper diacid monoester intermediate (IV) with an equimolar amount of sodium borohydride in the solvent (such as anhydrous tetrahydrofuran, etc.), adding an equimolar amount of iodine under stirring, after sufficient reaction (if no The bubble is generated, the color of the solution is reduced to colorless, and the tetrahydrofuran is distilled off under reduced pressure, and the organic solvent (such as ethyl acetate) is dissolved and washed with water, and then the organic solvent is removed to obtain a colorless transparent viscous liquid.
- the solvent such as anhydrous tetrahydrofuran, etc.
- Figure 1 is a graph showing the in vitro plasma in vivo decomposition of propofol hydroxybutyrate of the present invention.
- Figure 2 is a graph showing the in vitro plasma in vivo decomposition of propofol hydroxyvalerate of the present invention.

- mice were injected into the tail vein, and the disappearance of the Forepaw Righting Reflex (FRR) was used as the endpoint of the anesthesia. The fore paw reflex was restored to the anesthesia recovery index. The results indicate: ED 5 of the test drug of the present invention.
- FRR Forepaw Righting Reflex
- the compound of the invention makes 2,6-diisopropylphenol (propofol) form its hydroxy acid ester derivative, overcomes the disadvantage that the hydroxyl group in the propofol structure is easily oxidized, and has stability in vitro, It can be rapidly decomposed into the body, so it can be applied in centrally inhibiting drugs that produce sedative, hypnotic and/or anesthetic effects on animals or humans via intravenous or extravascular routes, increasing the scope of application of propofol prodrugs.
