Embodiment 1

[0067] The preparation of embodiment 1 rotundine hydrochloride 0.5 hydrate gets the fine powder 6.22g of rotundine in 250ml flask, adds 50ml of water, stirs, heats, adds the hydrochloric acid solution of appropriate amount 4M, stirs, control solution pH=below 1.5, Continue to stir for about 4 hours, filter, decompress and concentrate for a while, place, slowly cool to about 0°C, place, wait for the precipitate to be fully separated, filter, and wash the solid obtained three times with ice-cold water and a small amount of ice-cold ethanol, and filter with suction , dilute the obtained crystals, blow dry at about 25°C for 3 hours, and then dry at about 50°C for about 5 hours to obtain 5.53 grams of off-white solid; Identification: 1) Take 10 mg of the product prepared in this example, add 2ml of water to dissolve it , add 1 drop of potassium dichromate test solution, promptly produce yellow precipitate; (2) get the product 10mg that this embodiment prepares, add 2ml water to diss...

Embodiment 2

[0068] The preparation of embodiment 2 rotundine hydrochloride 0.5 hydrate gets the fine powder 5.36g of rotundine, ethanol 5ml, water 50ml in the 250ml flask, stirs, heats, feeds hydrogen chloride gas, stirs, control solution pH=below 1.5, Continue to stir for about 4 hours, slowly cool to about -5°C, place it until the precipitate is fully separated, filter, wash with ice-cold ethanol, filter with suction, dilute the obtained crystals, and dry it with air at about 28°C for 6 hours, then re-dry it at about 40°C Dry it in a vacuum oven for about 2 hours (the degree of vacuum is about 0.08 MPa), and obtain 2.47 grams of off-white solid; Identification: 1) Take 10 mg of the product prepared in this example, add 2 ml of water to dissolve, add 1 drop of potassium dichromate test solution , that is, a yellow precipitate is produced; (2) take 10 mg of the product prepared in this embodiment, add 2 ml of water to dissolve, add 1 drop of dilute potassium ferricyanide test solution, tha...

Embodiment 3

[0069] The preparation of embodiment 3 rotundine hydrochloride 0.75 hydrate gets the fine powder 5.36g of rotundine, adds ethanol 50ml in the 250ml flask, stirs, and heating makes dissolving, adds the hydrochloric acid solution of right amount 6M, stirs, and controls solution pH= Below 1.5, stir for about 30 minutes, decompress and concentrate for a while, let stand, slowly cool to about -20°C, let stand overnight, wait until the precipitate is fully separated, filter, wash with ice-cold ethanol, and suction filter, put the obtained solid in a flask , add 2ml of water, add an appropriate volume of 90% ethanol and heat it at about 78°C to dissolve, carry out recrystallization operation, keep it below 0°C, place it until the crystals are fully separated, filter with suction, dilute the obtained crystals, and drum at about 28°C Air-dried for 3 hours, then dried at about 60°C for about 2 hours to obtain 3.23 grams of light yellow crystals; identification: 1) Take 10 mg of the produ...

Abstract

Dibenzo quinolizine compound entity has relatively low hygroscopicity and relatively high storage stability, and is applicable to preparation of analgesic, sedative, hypnotic and tranquillizing medicines, medicines for treating hypertension, arrhythmia and functional dyspepsia, stopping cough, resisting schizophrenia and heroin and other drug dependence, reversing tumor cell drug resistance and delaying or reducing myocardial ischemia reperfusion injury, calcium antagonists, and medicines for protecting the liver and preventing visceral implicated reaction and other effects, which are applied to humans or animals.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to provide analgesia, sedation, hypnosis, stability, treatment of hypertension, anti-arrhythmia, functional dyspepsia, cough, anti-schizophrenia, detoxification, reversal of drug resistance of tumor cells A dibenzoquinazine alkaloid compound entity that delays or alleviates myocardial ischemia-reperfusion injury and uses thereof-rotundine hydrochloride crystalline hydrate and its preparation and use. Background technique [0002] Polymorphic forms of chemical drugs play an important role in drug research. In the field of pharmacology, the research work on drug crystal forms and drug hydrates or drug solvates has been listed in the research scope of the National Twelfth Five-Year Major New Drug Innovation Science and Technology Major Project. Solvents of compounds, including hydrates, have been prepared and used in medicines for a long time. For example, the antineoplastic drug cyc...
