Description

Benzamide compound activates the application of hiding in HIV (human immunodeficiency virus) medicine in preparation
Technical field
The present invention relates to field of medicaments, be specifically related to benzamide compound and activate the application of hiding in HIV (human immunodeficiency virus) medicine in preparation.
Background technology
Acquired immune deficiency syndrome (AIDS) (AIDS) is by HIV (human immunodeficiency virus) (HIV), to be infected the infectious disease of the serious harm human health causing, be one of the most serious public disease of facing of the current mankind, its effective prevention and thoroughly healing are still global difficult problems.On the 19th the World AIDS Conference of holding on July 22nd, 2012 (http://aids2012.org), international AIDS brainstrust is unanimously thought and be there is some evidence " mankind prevent and treat AIDS Epidemic and welcome Important Change point " " acquired immune deficiency syndrome (AIDS) changes a kind of chronic disease into gradually from ' century incurable disease ' ".This is because the existing approximately 30 kinds of retrovirus medicines in the whole world can form effective Therapeutic Method, if drug combination, i.e. " highly active antiretroviral therapy (HAART) ", HIV (human immunodeficiency virus) in patient body can be controlled to extremely low level, greatly delay PD, improve patient's life-span and quality of life.Yet existing medicine is treatment of AIDS thoroughly all, the infected needs lifelong medication, once drug withdrawal, the HIV (human immunodeficiency virus) amount in body will rebound fast.Therefore, current the World AIDS Conference is classified the following mankind as by " treatment of AIDS " and is prevented and treated one of most important target of acquired immune deficiency syndrome (AIDS).
Existence just because of latent infection and the bunker of hiding of HIV (human immunodeficiency virus), just causes existing AIDS-treating medicine cannot eradicate HIV (human immunodeficiency virus), thoroughly treatment of AIDS.The latent infection of so-called HIV (human immunodeficiency virus), is incorporated into its viral gene in people's genome after referring to AIDS viral infection host cell, keep the latency that do not copy, so the medicine that those antiviral copy does not have inhibitory action to it.Once but condition maturity (after drug withdrawal), these viruses of hiding can be recovered replication capacity again, discharge the virion making new advances and infect contiguous immunocyte.The bunker of hiding of HIV (human immunodeficiency virus) has the persistency of height, comprises that highly active antiretroviral therapy (HARRT claims again " HAART ") is all helpless to the bunker of hiding of removing HIV (human immunodeficiency virus) in interior chemotherapy when its tranquillization.
At present, generally believe that removing the HIV (human immunodeficiency virus) bunker of hiding is one of key of thorough treatment of AIDS.Research finds that histon deacetylase (HDAC) (HDAC) inhibitor, Protein kinase C (PKC) antagonist, dnmt rna (DNMT) inhibitor etc. all have certain activation to the HIV (human immunodeficiency virus) of hiding.In the recent period, on the top Scientific Periodicals < < Nature > > magazine of the world, reported a up-to-date breakthrough achievement: a kind of cancer therapy drug Vorinostat--Vorinostat(HDAC inhibitor) can activate the HIV (human immunodeficiency virus) of hiding in human body.In its experiment, research worker takes medicine Vorinostat to eight patients infected hivs, and these eight the infecteds are before at antiretroviral therapy, and stable disease.After having taken Vorinostat, the virus load in patient body has on average increased by 4.5 times, and this has implied that the HIV (human immunodeficiency virus) of hiding in their body after taking medicine is activated.This part of report proved that hdac inhibitor can excite the HIV (human immunodeficiency virus) of hiding in bunker effectively first in transforming clinical research, is key one step of thorough treatment of AIDS.In combining under use of such medicine and anti-reverse transcription medicine, treatment of AIDS becomes possibility.
Chidamide (CS055/HBI-8000); selectivity Antibiotic FR 901228 (HDACi); chemistry N-(2-amino-4-fluorophenyl)-4-[N-[(E by name)-3-(3-pyridine) acryloyl group] aminomethyl] Benzoylamide (N-(2-Amino-4-fluorophenyl)-4-[N-[(E)-3-(3-pyridyl) acryloyl] aminomethyl] benzamide, C 22h 19fN 4o 2, molecular weight390.41), be a kind of novel Antibiotic FR 901228, it has anti-tumor activity and can strengthen the cytotoxicity for the immunocyte mediation of tumor cell.But up to now, at home and abroad there is no chidamide at the application of the medicine of hiding as activation HIV (human immunodeficiency virus), i.e. the research report of the functional healing of acquired immune deficiency syndrome (AIDS) aspect.
The major reason that acquired immune deficiency syndrome (AIDS) is difficult to be cured is completely can hide form the storehouse of hiding in tranquillization memory CD4+ cell due to HIV (human immunodeficiency virus).To remove the HIV (human immunodeficiency virus) in patient body completely, need to remove on the one hand the inside and outside virion with infection ability of infection cell, also will remove on the other hand those and continue to hide and be hidden in the provirus gene of hiding in bunker in infection cell neutralization.Now, just concentrating in the world advantage strength at the strategy of research and development " shock and kill " (first stimulate latent virus to bring back to life with HIV (human immunodeficiency virus) activator, then treat with Anti-AIDS Drugs), to be used as the scheme for the treatment of of AIDS.
