Abstract
The invention discloses a kind of new salbutamol drug salts salbutamol fumarate and preparation method thereof.The novel substance exists in the form of salts, there is preferable stability, and solubility in aqueous improves a lot than former drugs salbutamol, with larger range of application.It, with salbutamol and fumaric acid as raw material, is 3 in ratio that the preparation method of this salt is:1~1:Under conditions of 2, the alcoholic solution of fumaric acid will be dissolved with and be slowly dropped in the alcoholic solution containing a certain amount of salbutamol, 3 ~ 4 h are heated to reflux afterwards, directly filtered, that is, obtain salbutamol fumarate, yield is more than 85%.
Description
Technical field
The present invention relates to medicinal chemistry art, and in particular to salbutamol fumarate and preparation method thereof.
Technical background
Bronchial astehma is a kind of non-specific disease of air flue, is also a kind of most common chronic to human health threat
Disease.The current whole world at least 300,000,000 people above asthmatics, and just have 30,000,000 asthmatic patients in China, the incidence of disease is about
It is 1.3%.Though control of the salbutamol as a kind of air flue diastole agent for the treatment of bronchial disease to disease has certain treatment
Effect, but single salbutamol medicine can have some side effects to health, therefore salbutamol is done further
It is necessary to explore with research.
Salbutamol fumarate is such as shown in (I).
Entitled 1- (hydroxymethyl phenyl of 4 hydroxyl -3) -2- (the tertiary fourth amino) ethanol of salbutamol chemistry, also known as methoxyphenamini hydrochloridum, be
A kind of selective β 2 receptor agonist, at present, in the market is more to be existed in the form of its sulfate, next to that the shape of hydrochloride
Formula.
Fumaric acid has been related to the form appearance of medicine fumarate, such as fumaric acid at present as the acceptable acid of medicine
Ketotifen piece.
Any report about salbutamol fumarate is not seen also at present.
The content of the invention
Object of the present invention is to provide a kind of new salbutamol drug salts-salbutamol fumarate and its preparation
Method.
The preparation method of salbutamol fumarate is mainly realized by the following aspects in the present invention:
(1) it, with salbutamol and fumaric acid as raw material, is 3 in ratio that its preparation method is:1~1:Under conditions of 2, by rich horse
The alcoholic solution of acid is slowly dropped in the alcohol solution containing a certain amount of salbutamol, and 3~4h, direct mistake are heated to reflux afterwards
Filter, that is, obtain salbutamol fumarate.
In above-mentioned (1), alcohol used is methyl alcohol, ethanol, normal propyl alcohol, isopropanol, n-butanol, isobutanol, ethylene glycol, glycerine.
In above-mentioned (1), the consumption of alcohols solvent used is 50~150mg solutes/g solvents.
The invention provides a kind of new salbutamol drug salts-salbutamol fumarate and preparation method thereof.And profit
With infrared spectrum (IR), proton nmr spectra (H1NMR), X-ray powder diffraction (XRD) experiment is entered to salbutamol fumarate
Row is characterized.
FTIR spectrum (FT-IR).
The FT-IR of salbutamol fumarate is obtained by Prestige-21 infrared spectrophotometers, and sample does background with KBr, red
External curve is shown in accompanying drawing 1.
Proton nmr spectra (H1-NMR)。
The hydrogen nuclear magnetic resonance spectrogram of salbutamol fumarate comes from the NMRs of Bruker AVANCE 500,000,000, and its figure is shown in
Accompanying drawing 2.
X-ray powder diffraction (XRD) method
The X-ray powder diffraction figure of salbutamol fumarate uses the X-ray powder of Philips X ' the Pert types equipped with Cu-Ka
Last diffractometer, powder diagram is shown in accompanying drawing 3.
The H of salbutamol fumarate1- NMR data is as follows:H1-NMR(D2O,500MHz):1.27 (s, 9H), 3.20-3.00
(m, 2H), 4.54 (s, 2H), 4.80 (dd, J=9.4,3.7Hz, 1H), 6.38 (s, 1H), 6.83 (d, J=8.3Hz, 1H),
7.15 (dd, J=8.4,2.4Hz, 1H), 7.23 (d, J=2.3Hz, 1H).
The X-ray powder diffraction instrument data of salbutamol fumarate are as follows:
