Description

The oxo-1-pyrrolidine ethanamide aseptic powdery of one kind (S) -4- hydroxyls -2 and its preparation Method
Technical field
The invention mainly relates to pharmaceutical technology field, and in particular to the OXo-1-pyrrolidine second of one kind note (S) -4- hydroxyls -2 Acid amides aseptic powdery and preparation method thereof.
Background technology
It is a kind of promotion study that cereboactive drug, which is also known as cereboactive drug, strengthens the new medicine for central nervous system of memory. Nootropics requires selection index system in cerebral cortex, with selection activation, protection and promotion damaged nerve cell functional rehabilitation Feature.Different from other neurologic agents be a little their above-mentioned effect not by network or olfactory bulb, but directly Act on cortex.Behavior is neither influenceed, also without calm excitation, therefore such medicine has caused the extensive concern of people and emerging Interest, the demand to such medicine is also growing day by day.
Oxiracetam (oxiracetam, CAS No.:62613-82-5) chemical entitled 4- hydroxyls -2- OXo-1-pyrrolidines Acetamide, is that (compound is disclosed in the anti anoxia class cereboactive drug that was synthesized first in 1974 of Italian ISFS.P.A companies US4118396), it is ring GABOB derivatives, Phosphorylcholine and phosphatidyl ethanolamine can be promoted to synthesize, promote brain metabolism, through blood brain Barrier, has stimulation to specific nervous centralis road, can improve intelligence and memory, to cerebrovascular disease, brain trauma, brain Knurl, intracranial infection, brain degenerative disease etc. also have preferable curative effect, and the drug toxicity is extremely low, no mutagenesis and carcinogenic work With and genotoxicity.Giorgio et al. discloses the chemical constitution and preparation method of Oxiracetam in US4118396, Chiodini et al. is disclosed in WO9306826A, and clinical effectiveness proves that the drug effect of the Oxiracetam of S configurations (left-handed) is better than R structures Type (dextrorotation), Oxiracetam and levo-oxiracetam structure are as follows.
The existing oxo-1-pyrrolidine ethanamide aseptic powdery of (S) -4- hydroxyls -2 its be primarily present preparation process impurity increase Substantially, without solid shape, be difficult to form skeleton, easily there is spray bottle phenomenon in freeze-drying process in product, and stability is poor, and shelf life is short The problems such as.
The content of the invention
It is an object of the invention to provide it is a kind of with solid form, good stability, shelf life length (S) -4- hydroxyls -2 Oxo-1-pyrrolidine ethanamide aseptic powdery.
Another object of the present invention is to provide the above-mentioned oxo-1-pyrrolidine ethanamide aseptic powdery of (S) -4- hydroxyls -2 Preparation method.
The purpose of the present invention is realized by following technical measures:
The oxo-1-pyrrolidine ethanamide aseptic powdery of one kind (S) -4- hydroxyls -2, it is characterised in that it is by following weight The supplementary material of percentage is made:(S) oxo-1-pyrrolidine ethanamide 30%~50% of -4- hydroxyls -2, additives 50%~ 70%, wherein the additives are sucrose, trehalose, mannitol, lactose, glucose, maltose, glucan, albumin, poly- second Glycol, glycerine, Serine, vitamin C, sodium thiosulfate, methionine, sodium glutamate, alanine, glycine, methyl amimoacetic acid, One or more in phosphate, acetate, citrate.
Inventor has found in research process, selects specific additives species, coordinates specific supplementary material consumption proportion Relation, may be such that the oxo-1-pyrrolidine ethanamide aseptic powdery of above-mentioned injection (S) -4- hydroxyls -2 in preparation process impurity level Increasing smaller, product has solid shape, easily forms skeleton, is not in spray bottle phenomenon in freezing dry process, and can Extend shelf life;The above-mentioned oxo-1-pyrrolidine ethanamide aseptic powdery of (S) -4- hydroxyls -2, it is characterised in that it is It is made by the supplementary material of following weight percents:(S) oxo-1-pyrrolidine ethanamide 35%~45% of -4- hydroxyls -2, L- ammonia Acid 20%~28%, mannitol 25%~38%, sodium glutamate 3%~9%, methionine 2%~10%.
In order to which further such that product impurity incrementss in preparation process are smaller, shelf life is longer, above-mentioned (S) -4- hydroxyls The oxo-1-pyrrolidine ethanamide aseptic powdery of base -2, it is characterised in that it is made by the supplementary material of following weight percents: (S) oxo-1-pyrrolidine ethanamide 38%~42% of -4- hydroxyls -2, Serine 22%~25%, mannitol 28%~ 33%, sodium glutamate 4%~7%, methionine 3%~6%.
Supplementary material needed for above-mentioned, is well known to those skilled in the art, in the market is commercially available.
