Description
Technical field
The present invention relates to the preparation and application of a kind of noval chemical compound；Specifically [2- (1H)-quinolinone -3- bases] aminomethyl phosphine
The preparation of acid esters and the application as influenza virus neuraminidase inhibitor.
Background technology
Avian influenza virus (avian influenza virus, AIV) belongs to influenza A virus, can be divided into 16 H
(H1-H16) hypotype and 9 N (N1-N9) hypotype, in the numerous hypotypes of influenza A virus, H5And H7For highly pathogenic bird flu disease
Poison.So far find that the avian influenza virus subtype of energy direct infection people has H5N1、H7N2、H7N3、H7N7、H9N2、H10N7、H7N9And
In December, 2013 is found that new bird flu H in China Jiangxi10N9Hypotype.The Symptoms of these hypotypes are each different, mainly may be used
To show as respiratory symptom, conjunctivitis or even death.Wherein highly pathogenic H5N1Hypotype and in March, 2013 on human body for the first time
It was found that new bird flu H7N9Hypotype is particularly noticeable.
1997, find the H of the energy direct infection mankind for the first time in Hong Kong5N1Hypotype.By the end of in July, 2014, the whole world is reported altogether
It has accused people and has infected highly pathogenic H5N1Bird flu 667, wherein 393 dead.Case is distributed in 16 countries, wherein, China
It is found that 45, dead 30.Most people infects H5N1Bird flu case is young man and children.The H of 2009 outbursts1N1Stream
Influenza Virus results in global high speed and propagates, serious threat is constituted to Global Health.By the end of in December, 2014 world
The H that health organization (World Health Organization, WHO) is announced1N1Influenza makes a definite diagnosis people more than 1,310,000, more than dead 14000
People.In March, 2013, finder infects H for the first time in China7N9Bird flu case, the new strain of bird flu found for the first time for the whole world are sub-
Type.End on January 25th, 2015, the H that the World Health Organization announces7N9494 people, dead 221 people are made a definite diagnosis in bird flu.
Anti-influenza virus medicament is broadly divided into two classes：M2 inhibitors of ion channels and NA inhibitor.M2 ion channels inhibit
Agent shows gastrointestinal tract and central nervous system serious side effects, and only effective to A types because being also easy to produce drug resistance, and clinic should
With being extremely restricted.And NA inhibitor is a kind of relatively new anti-A, Type B influenza virus drug, it is by being adhered to new shape
Into the glycoprotein on virion NA surfaces, the virus of host cell release new is prevented, and increases new virus self assemble, is reduced
Its diffusivity and infectivity.Therefore, NA inhibitor becomes the emphasis of current Tamiflu research.Up to the present, as god
The anti-influenza virus medicament listed through propylhomoserin enzyme inhibitor mainly has zanamivir (Zanamivir), oseltamivir
(Oseltamivir) and Peramivir (Peramivir).
2011, the Academia Sinica of TSRL Inc. of the U.S. and TaiWan, China was repaiied on the architecture basics of zanamivir
Decorations, separately design and have synthesized a series of zanamivir L-threonine derivatives of high therapeutic index and zanamivir phosphonic acid ester drug, this two classes drug
With significant NA inhibiting effect, it is possible to the medicine as anti influenza.
Drug research worker studies the neuraminic acid enzyme inhibition activity of a large amount of compounds in recent years.Middle promulgated by the State Council
Bright patent (CN101570521B) describe 4- tertiary butyl -6- phenyl -2- amino -6H-1,3- thiazine salt preparation method and its
Pharmaceutically it is used to prepare influenza virus neuraminidase inhibitor.
Chinese invention patent (CN101891705B；CN102204914B 4- alkyl-6-aryl -2- acyl ammonia) is respectively described
Base -1,3- thiazine -5- formic acid esters and 4- alkyl-6-aryl-5-acetyl-1,3-thiazines, which are used as, prepares neuraminidase inhibitor
Application.
