Abstract
A process is described for producing anhydrous beta -form of ((Z)-2-[[[(2-amino-4-thiazolyl)[[trans-(2S,3S)-2-methyl-4-oxo-1-sulfo-3-azetidinyl]carbamoyl]methylene]amino]oxy]-2-methylpropionic acid (also known as Aztreonam).
Description
Technical field
The present invention relates to a kind of crystal anhydrous beta type (Z)-2-[[[(2-amino-4-thiazole) [[suitable-(2S, 3S)-2-methyl-4-oxo-1-sulfo--3-azetidinyl]-carbamyl] methylene radical] amino] oxo]-2 Methylpropionic acid " (Z)-2-[[[(2-amino-4-thiazolyl) [[trans-(2S, 3S)-2-methyl-4-oxo-1-sulfo-3-azetidinyl]-carbamoyl] methylene] amino] oxy]-2-methylpropionic acid " production method of (being also referred to as aztreonam).
Background technology
Aztreonam shown in the molecular formula I (Aztreonam) is a kind of monocycle beta-lactam antibiotics preparation (synthetic monocyclic beta-lactam antimicrobialagent) of synthetic, and (gram-negative organism) has anti-microbial activity to gram-negative micro-organism.
Molecular formula I
Some reference have disclosed the technology of preparing of aztreonam, for example: american documentation literature 4,775,670 and 5,194,604.Present known aztreonam has polymorphism (polymorphism), and american documentation literature 4,826,973 reported four kinds of different aztreonam crystalline structure forms, i.e. a-, and β-, γ-, δ-type.The a-type is hydrated crystal (hydrated crystals), comprises the moisture of 7-14% usually, and storage stability is poor.Therefore, should convert it into β-type, the latter possesses anhydrous (anhydrous), moistureproof (substantially non-hygroscopic) and have good flowability (possesses good flowability), less surface-area (low surface area), stronger solid-state stability features such as (enhanced solid state stability), be more suitable for as medicinal preparations.
American documentation literature the 4th, 946, the preparation flow of describing β-type aztreonam No. 838 promptly makes a-type crystallization (crystallization) by raw spirit (anhydrous alcohol).Wherein, the a-type can be dissolved in methyl alcohol and ethanol under 55-60 ℃.Under these conditions, the a-type can temporary transient dissolving, recrystallize (recrystallises), formation β-type aztreonam naturally afterwards.Above-mentioned flow process is not suitable for carrying out sterile production (sterile preparation), because aztreonam does not have (in solution) maintenance sufficiently long time in raw spirit, to carry out sterile filtration (asepticfiltration).
American documentation literature the 4th, 946 has been introduced the method for the another kind of β of preparation-type aztreonam No. 838.Wherein, the a-type is dissolved in dehydrated alcohol (anhydrous ethanol) with triethylamine salt form (triethylamine salt), just can obtain β-type aztreonam to wherein adding anhydrous chlorides of rase hydrogen solution (anhydroushydrogen chloride solution) afterwards.Though this method is suitable for carrying out sterile filtration, target product is polluted by triethylamine hydrochloride (triethylaminehydrochloride).
At american documentation literature the 4th, 946, in another production sequence that No. 838 are introduced, at dipolar aprotic solvent (aprotic solvent), for example in the acetonitrile (acetonitrile), add binding agent (silylating agent) the a-type is handled, to obtain the solution of aztreonam bonding derivative (Aztreonam as silyl derivative).Add ethanol in above-mentioned solution, β-type is precipitated comes out.The output of this method is very low, in bonding process (silylationstep), the a-type must be dissolved simultaneously.Purpose of the present invention described below will address these problems exactly.
Summary of the invention
The present invention relates to a kind of brand-new Production Flow Chart, with preparation high purity, aseptic crystal-anhydrous beta-type aztreonam.Utilize the present invention, just no longer need to add triethylamine or binding agent when in dehydrated alcohol (absolute ethanol), preparing a-type aztreonam solution, and the solution of preparation like this can carry out sterile filtration to generate aseptic β-type aztreonam crystal.
It is worth noting that the present invention can make the a-type be dissolved in dehydrated alcohol at low temperatures.A-type aztreonam can be dissolved in dehydrated alcohol between-10-+15 ℃, when temperature is increased to 50-55 ℃, form β-N-type waferN by recrystallize.If temperature rests on-10-+15 ℃, aztreonam will can recrystallize in this solution.This uncommon solvability of a-type aztreonam (solubility characteristic) is not report in the literature so far.But, american documentation literature 4,912, in No. 211 6 pairs of another kind of microbiotic of example (antibiotic)---the similar solvability of cefotaxime sodium (cefotaxime sodium) is described.Above-mentioned a-type aztreonam solution can be sloughed color after by carbon treatment, and sterilizing filter that also can be by 0.2 micron is to carry out sterile preparation (aseptic preparation).
A-type aztreonam is dissolved in raw spirit, especially dehydrated alcohol.Temperature range is-10-+15 ℃, and optimum temps is 5-10 ℃.Keep the said temperature level, application of active carbon (activated carbon) is handled respectively, purifies filter (clarification filter) and sterile filters (sterile filter) and filters a-type aztreonam solution to obtain sterile solution.Afterwards, the temperature of aseptic filtrate (sterile filtrate) is risen to 50-55 ℃, will form anhydrous beta-type aztreonam crystallization.At last, above-mentioned product also need pass through vacuum filtration and drying.β-type aztreonam by these program preparations is suitable for as medicinal preparations (pharmaceutical agent), with basic substance, after for example L-arginine (L-arginine) mixes, can be by intravenous injection and muscle injection mode medication (intravenous and intramuscular administration).
Compared with former technology, main beneficial effect of the present invention is to simplify production process.The Production Flow Chart of prior art needs extra step, promptly must add triethylamine or binding agent and make the dissolving of a-type aztreonam, thereby carry out sterile filtration.And in flow process of the present invention, a-type aztreonam can directly be dissolved in ethanol at low temperatures to obtain a solution, and this solution is fit to be used for preparing aseptic β-type aztreonam.
By the flow process that describes below, can finish by a-type aztreonam preparation β-type aztreonam.
Description of drawings
Embodiment
Under 8-10 ℃,, stir 30 minutes to obtain limpid liquid with in the dehydrated alcohol of a-type aztreonam (40g) adding precooling (2400ml).Still under 8-10 ℃, handled above-mentioned solution 15 minutes with activated carbon (1g).Suspension (suspension) is filtered by flocculating aids (celite), and surplus materials washs with ethanol (50ml).Afterwards, filtrate (filtrate) slowly was heated to 50-55 ℃ in 2 hours, and recrystallize forms β-type aztreonam.The suspension of heating is cooled to 15-20 ℃, stirs 1 hour and filters once more.Above-mentioned crystalline product carries out drying in a vacuum, and finally forms the 33g end product.Utilize IR spectrum (IR spectrum), powder x ray diffraction pattern (powder X-ray diffraction pattern) and dsc (differential scanning calorimetry) to confirm that this end product is exactly β-type aztreonam.
