Technical field
The invention belongs to technical field of medicine synthesis, and in particular to a kind of preparation side of high-purity Vidarabine Monophosphate
Method.
Background technology
Vidarabine Monophosphate(Vidarabine MonopHospHate, structural formula one),
Entitled 9- (β-D- the arabinofuranoses)-adenine 5'- phosplates of chemistry.
Vidarabine Monophosphate is the mono-phosphorylated compound of arabinosy ladenosine, is that a kind of artificial synthesized adenosine class resists
Viral medicine.Vidarabine Monophosphate enters after cell, and arabinosy ladenosine diphosphonic acid and arabinosy ladenosine triphosphoric acid are generated by phosphorylation,
Antiviral activity is derived mainly from arabinosy ladenosine triphosphoric acid.Current Vidarabine Monophosphate is mainly used in chronic viral in China
Hepatitis, herpes simplex virus, herpes zoster virus, vaccinia virus and many animals herpesviral and a small number of oncornavirus RNAs
Deng.Vidarabine Monophosphate clinical efficacy is definite, but its drug safety and adverse reaction it is similarly subjected to extensive concern.In medicine
During thing Clinical practice, the adverse reaction of generation is relevant except the pharmacological property with medication people's constitution and medicine in itself
Outside, also there is very big relation with medicine impurity present in, for example, causing the main of allergy using antibiotic such as penicillin
Reason is containing macromolecule impurities such as polymers among medicine.Because Vidarabine Monophosphate is big in the quantity of China, it is
The security of clinical application is further ensured that, by improving the process exploitation of Vidarabine Monophosphate purity to reduce in medicine
Impurity just seems particularly necessary.
At present majority producers prepare synthetic route that Vidarabine Monophosphate generally uses for:Arabinosy ladenosine and POCl3
Phosphorylation reaction is carried out in organic solvent, and Vidarabine Monophosphate is obtained after hydrolysis.
According to reaction mechanism, during phosphorylation reaction, while required 5'- phosplates are obtained, 3' can be also produced,
5'- bisphosphates(Structural formula two), 5', 5'- monophosphate diester(Structural formula three), 3', 5'- monophosphate diester(Structural formula four)Deng
Major impurity.
Because above-mentioned major impurity is similar with the physicochemical property of Vidarabine Monophosphate, conventional recrystallization method can not be thorough
Bottom is removed, and the finished product purity of gained is relatively low.
Old crooked chisel, Chen Shucheng, leaf wild goose ripple Vidarabine Monophosphates synthetic method improves [J] massages and medical science of recovery therapy,
2013,4(2):98-99 is reported, and arabinosy ladenosine carries out low-temp reaction with POCl3 through high temperature dehydration in triethyl phosphate,
Hydrolysis, after dichloromethane extraction, water layer adjusts pH crystallizations to obtain Vidarabine Monophosphate product, and yield is not referred to pure up to more than 98%
Degree.
Wang Zhengxiong, Improved synthesis [J] Chemical Engineerings and the equipment, 2008 (12) of ginger Liu Wei Vidarabine Monophosphates:75-
76, the synthetic method of report is similar, and difference is, water layer is adjusted after pH, is slowly added to ethanol crystallization and obtains crude product, crude product
Vidarabine Monophosphate finished product is recrystallized to obtain in ethanol, purifying aqueous systems, total recovery 66.6%, content 99.1% there are no purity
Report(Explanation:Content is used to reflect the amount of Main Ingredients and Appearance in test sample, is relative relative to one of standard items or reference substance
Value, and purity is absolute value, the content for reflecting impurity in test sample.Even if the purity of a medicine is relatively low, its content
May also > 100%).
Zhou Lihong(Synthesis, Structural Identification and the quality research [master thesis] of Vidarabine Monophosphate, Central China science and technology
University 2006)Use, arabinosy ladenosine reacts with POCl3 in pyridine, acetonitrile mixed system, hydrolyze to obtain crude product, crude product warp
Water for injection recrystallizes to obtain Vidarabine Monophosphate finished product, total recovery about 73%.The route needs to use substantial amounts of pyridine and second
Nitrile, both expensive, toxicity are larger, and miscible with water, reclaim difficult, and production cost is high, environmental pollution is big, business metaplasia
The feasibility of production is relatively low.
Patent CN103204890B is used, and arabinosy ladenosine, in dichloromethane system, adds acid binding agent with POCl3
DIPEA, the reaction of catalyst DMAP, reaction filters to obtain solids after terminating, de- by activated carbon
Color etc. post-processes to obtain crude product, most afterwards through recrystallizing to obtain Vidarabine Monophosphate finished product, total recovery 78.1%.The route reaction is separated out
Solid directly filter, because reaction terminates rear system and still remains a certain amount of POCl3, unprocessed direct filtering meeting
Cause certain potential safety hazard.The patent has no that purity is reported.
The Vidarabine Monophosphate preparation method that current existing patented technology and document are reported is substantially similar, arabinose gland
Glycosides and POCl3 carry out phosphorylation reaction in organic solvent, through hydrolysis, crystallization, be recrystallized to give Vidarabine Monophosphate into
Product, because the major impurity of Vidarabine Monophosphate is very difficult to remove by conventional recrystallization, therefore existing patent document is almost
The not no report on purity data.Scope of the purity of current most products on the market 98.0%~98.5%, by multiple
Although recrystallization can improve the purity of product to a certain extent, because Vidarabine Monophosphate has certain dissolving in water
Degree, with recrystallization number of times increase, total yield of products is reduced on the contrary.It is badly in need of researching and developing a kind of high-purity, in high yield for this
