Abstract

Description

Inhibitors of viral replication, their process of preparation and their
therapeutical uses
The present invention relates to compounds, their use in the treatment or the prevention of viral disorders, including HIV. The present invention also relates to methods for the preparation of such compounds. The present invention also relates to pharmaceutical compositions comprising such compounds. The present invention also relates to the treatment of viral infections by the administration of a therapeutically efficient amount of such compounds.
The Acquired Immuno Deficiency Syndrome (AIDS) is a disease due to infection by the Human Immunodeficiency Virus (HIV). HIV is a retrovirus, belonging to the subclass of primate lentiviruses. Two types of HIV have been identified, HIV-1 and HIV-2. HIV-1 is responsible for the larger part of the AIDS global epidemic in the world, with virtually every country reporting cases.
Currently HIV infected patients are treated with Highly Active Anti Retroviral Therapies (HAART) that rely on a combination of several drugs belonging to different classes. Up to 2003, all approved anti-HIV drugs were inhibitors of the catalytic activity of two viral enzymes, Reverse Transcriptase (RT) inhibitors and Protease (PR) inhibitors. Reverse Transcriptase inhibitors include two different classes, Nucleoside/Nucleotide RT Inhibitors (NRTI) and Non Nucleoside RT Inhibitors (NNRTI). In 2003 a new class of Anti-retroviral drug (ARV), Fusion inhibitor (Enfuvirtide) was introduced (Cervia et al, Clin Infect Dis., 2003, 37(8):1 102-6). And lately, in 2007, two other classes of ARV were approved, Entry inhibitors (Maraviroc (Pfizer)) targeting the CCR5 co-receptor, and Integrase inhibitors (Raltegravir (Merck)) (Hughes et al, J Infect., 2008, 57(1 ):1 -10.)- Although these three novel drugs were very useful to treat patients in therapeutic failure due to multiresistance to RT and PR inhibitors, resistance mutations against these drugs have already been reported.
Although the development of these potent anti-HIV drugs, has allowed HIV-infected people to live longer and to benefit of a higher quality of life, it is clear that these drugs do not cure the HIV infection. Moreover, their prolonged use often results in significant toxicity and in the emergence of drug-resistant viruses. Importantly, the ability of HIV to establish latent reservoirs early in the course of infection ensures the persistence of the virus even in the face of intensive drug therapy and vigorous antiviral immune response. Thus, there is a continuous need for the development of novel anti-HIV therapies or a 2008, 13(3):393-416.). Document of Christ et al (Christ et al, Nat. Chem. Biol., 2010, 6: 442.) and documents WO 2007/131350, WO 2009/062285, WO 2009/062288, WO 2009/062289, WO 2009/062308, WO 2010/130034, WO 2010/130842, WO 201 1/015641 , WO201 1/076765, WO 2012/003498 and WO 2012/0033735 describe partially or totally unsaturated heterocyclic derivatives as anti-HIV agents.
Document WO 2012/003497 describes napthyl derivatives as anti-HIV agents.
However, these compounds are different from the compounds according to the invention. Summary of the Invention
The present invention relates to compounds that are able to totally or partially solve the above-mentioned problems and drawbacks. The present invention provides new antiviral agents, especially anti-retroviral agents, and more particularly anti-HIV compounds.
The compounds according the invention are inhibitors of HIV replication as assessed by HIV-1 replication assay as herein-detailed. These compounds are thus useful agents for treating or preventing virus, such as HIV, or other viral pathogenic diseases or disorders, by inhibiting replication of the virus into the host infected cells.
Therefore, the compounds according to the invention constitute a useful class of new potent antiviral compounds that can be used in the treatment and/or prevention of viral infections in animals, mammals and humans, more specifically for the treatment and/or prevention of HIV in humans.
The present invention further relates to such compounds for their use as a medicine, to the use of such compounds as medicines, more specifically as antiviral agents, and to their use for the manufacture of medicaments for treating and/or preventing viral infections, in particular retroviral infections such as, but not limited to, HIV in humans. The invention also relates to pharmaceutical compositions comprising such compounds in an antiviral effective amount, optionally in combination with at least one further antiviral agent. The present invention further relates to such pharmaceutical composition for its use for the treatment of an HIV infection in a mammal being infected or having a risk to be infected by the HIV.
The present invention also relates to a method of treatment or prevention of viral infections, in particular retroviral infections such as, but not limited to HIV in humans by the administration of one or more such compounds, optionally in combination with one or more other antiviral agents, to a patient in need thereof.
The present invention also relates to a method of inhibiting the replication of HIV comprising exposing the virus to an effective amount of one or more such compounds under conditions where replication of HIV is inhibited.
In a first aspect, the invention provides compounds comprising a 6-membered carbocycle or heterocycle, said compounds having a structure according to formula (A):

Antiviral activity
The antiviral activity, particularly against HIV, of compounds according to the invention is evaluated by the protocol described below.
Preparation of Virus stock of the NL4-3 strain of HIV-1 (Adachi et al, J Virol, 1986, 59(2):284-91 ).
The virus was prepared as described in Lopez et al (Lopez et al, Proc Natl Acad Sci U S A., 2006, 103(40): 14947-52, by transfecting 2 x 106 293T cells (CRL-1573, ATCC ) with following modifications: 6μg of NL4-3 proviral DNA molecular clone were mixed with Fugene 6 transfection reagent from Roche, and used according to manufacturer's instructions. Forty eight hours later, transfected cell supernatants were harvested, filtered through 0.45^m-pore-size filters, quantified for HIV-1 p24 antigen by using a Innotest HIV antigen mAb assay (Ingen) according to manufacturer's instructions, and used in infection experiments.
Preparation of compounds:
Serial dilutions of compounds to be tested were prepared in complete RPMI medium from 10mM DMSO stock solutions, and distributed in a volume of 20 I in 96 well Falcon 353072 Microtest™ tissue culture plate, in order to get 0.5% DMSO final concentration in each well, after the addition of infected cells. Control wells contained also 0.5% DMSO final concentration but no compound.
Infection of cells:
MT4 cells (from the NIH AIDS Research and Reference Reagent Program) in RPMI complete medium were counted (10X106 cells per well in Falcon 353047 Multiwell™ 24 well) and infected for 2 hours at 37°, at a multiplicity of infection (moi) of 0.0001 -0.00001. Cells were then centrifuged 3min at 3000rpm, and washed two times in 1 ml PBS to remove viruses that have not entered in cells. Infected cells were resuspended in complete RPMI at 1 .25x106 cells/ml, and 80 I of infected cells were distributed in each well containing compounds to be tested or control wells. The plates were then incubated at 37°for 5 days.
Assay used to measure the inhibition of HIV replication by the compounds (according to Gregg S. Jones et al., Antimicrobial Agents and Chemotherapy, 2009, 53 (3): 1 194- 1203).
After 5 days of incubation, 50 I of CellTiter-Glo reagent (Promega Biosciences, Inc., Madison Wl, USA) were added to each well. Cell lysis was carried out at room temperature during 10min, 150μΙ of lysates were transferred in Packard Optiplate 96 well, and luminescence was read on a Fluoroskan (Thermo Scientific).
The EC50, or effective concentration 50, is the concentration of compound leading to 50% of cyto-protection in a Cell-Titer-Glo® viability assay based on MT4 cells infected with NL4-3 virus.
