Abstract
The invention relates to the use of CY in preparing smooth muscle spasmolysis agent, and in preparing medicaments for treating stomach and intestinal spasm colicky pain, intestine excitable syndrome, ulcerative colitis, stomach and intestine dysfunction, and functional diarrhea.
Description
Technical field:
The present invention relates to medical technical field, exactly is that morpholine methyltetralone (CY) is used to prepare the purposes of smooth muscle spasmolysis agent.
Background technology
The chemical name of CY is a morpholine methyltetralone
(3,4-dihydro-2-(4-morpholinylmethyl)-1 (2H)-naphthalenone), this chemical compound in 1977 by Welch, Willard M.; Harbert, Charles A.; Sarges, Reinhard; Stratten, Wilford P.; Weissman waits the people successfully to synthesize, and its analgesic activities is investigated.The result shows that this chemical compound has more weak analgesic activities, but does not see the report of relevant CY diastole smooth muscle effect so far, and the inventor finds first that through many-sided experiment screening this chemical compound has the smooth muscle spasmolysis effect.
The chemical system title of morpholine methyltetralone is 2-(4-morpholine methyl)-1-tetralone, and its synthetic method is as follows
With 4.20g (0.028mol) 1-tetralone, 2.50g (0.029mol) morpholine mixes with the 10mL absolute methanol, regulate pH=2 with the saturated methanol solution of hydrogen chloride, add 2.25g (0.075mol) paraformaldehyde again, reflux 6h, separate out solid after the cooling, sucking filtration, use methanol wash, get white solid, use the absolute methanol recrystallization, obtain 3-(4-morpholine methyl)-1-tetralone hydrochlorate white solid, productive rate 77.1%.CY is soluble in water, is insoluble to ether, ethyl acetate, cyclohexane extraction, chloroform, is slightly soluble in methanol, ethanol, acetone.
Summary of the invention:
The present invention provides the purposes of treatment smooth muscle spasm to morpholine methyltetralone (CY).
Studies show that: the strong contraction of smooth muscle causes spasm and can cause multiple disease, can cause asthma as bronchial muscular spasm, the gastrointestinal smooth muscular spasm can cause stomachache, the biliary tract smooth muscle contraction can cause biliary colic, the strong contraction of bladder can cause urine urgency-frequency, and uterine smooth muscle shrinks may cause premature labor, influences the fetus normal development, so research smooth muscle spasmolysis medicine has very big realistic meaning, and diseases such as treatment asthma, frequent micturition, urgent micturition, the various angor of alleviation are all had directive significance and reference value.
We studies show that: CY can reduce the tension force and the amplitude of isolated small intestines of rabbits spontaneous activity, isolated small intestines of rabbits, colon, gallbladder that diastole acetylcholine, barium chloride, potassium chloride shrink; The stripped bladder of the rabbit that diastole acetylcholine, potassium chloride shrink, trachea.The CY gastric infusion can obviously suppress the diarrhea of mouse due to Oleum Ricini, magnesium sulfate, the liquid paraffin, and the intestinal propulsion and the large intestine that also can obviously suppress normal mouse advance.Therefore, CY can be used to prepare the spasmolytic for the treatment of smooth muscle spasm.

4, experimental technique
4.1 effect: after treating the specimen tension stability, in bathing pipe, add the CY (10 of variable concentrations respectively to the isolated small intestines of rabbits spontaneous activity
-4Mol/L, 0.3 * 10
-4Mol/L, 10
-3Mol/L) 0.1ml and aqueous solvent, the variation of observing and writing down small intestinal shrinkage curve under every kind of concentration is before the record administration, the variation of tension force, amplitude and frequency after the administration 0,5,10,15,20 minute the time.Experimental data is represented with means standard deviation, and is made paired t-test, the significance of judgement difference.
4.2 to causing the effect that isolated small intestines of rabbits, colon, gallbladder, bladder, trachea that the convulsion agent causes shrink: after treating the specimen tension stability, in bathing pipe, add and cause convulsion agent (acecoline 1mg/ml, barium chloride 10%, potassium chloride 60mmol/L), after obtaining maximum collapse, fully the flushing tissue adds with the convulsion agent that causes of concentration and induces contrast to shrink once more, when with preceding once shrink basically identical after, totally add CY (10 respectively
-5Mol/L~10
-3Mol/L), record amount effect curve.So that the maximum shrinkage amplitude of convulsion agent is 100%, draws amount effect curve, and data are represented with meansigma methods ± standard error, and obtained EC
50
5, experimental result: (table 1~table 8, Fig. 1~Fig. 5), by harmony in the exterior figure as can be known CY can reduce the tension force and the amplitude of isolated small intestines of rabbits spontaneous activity, isolated small intestines of rabbits, colon, gallbladder that diastole acetylcholine, barium chloride, potassium chloride shrink; The stripped bladder of the rabbit that diastole acetylcholine, potassium chloride shrink, trachea.
