4-OXOQUINOLINE COMPOUNDS AND UTILIZATION THEREOF AS HIV INTEGRASE INHIBITORS

Description

[0001] The present invention relates to a novel 4-oxoquinoline compound useful as an anti-HIV agent and a pharmaceutically acceptable salt thereof. The present invention also relates to a novel use of a certain 4-oxoquinoline compound and a pharmaceutically acceptable salt thereof as anti-HIV agents. More particularly, the present invention relates to an anti-HIV agent containing a 4-oxoquinoline compound that particularly shows an anti-HIV action based on an integrase inhibitory activity thereof, or a pharmaceutically acceptable salt thereof.

[0002] HIV (Human Immunodeficiency Virus (type 1)) belonging to retrovirus is a causative virus of AIDS (Acquired Immunodeficiency Syndrome).

[0003] HIV targets CD4 positive cell groups such as helper T cell, macrophage and dendritic cell and destroys these immunocompetent cells to cause immunodeficiency.

[0004] Accordingly, a pharmaceutical agent that eradicates HIV in the body or suppresses its growth is effective for the treatment or prophylaxis of AIDS.

[0005] HIV possesses a bimolecular RNA gene in a core protein, and which is covered with an envelope protein. The RNA codes for several enzymes (protease, reverse transcriptase, integrase) characteristic of the virus and the like, and has translated reverse transcriptase and integrase in the core, as well as protease inside and outside the core.

[0006] HIV attaches to and invades a host cell, causes uncoating, and releases a complex of RNA and integrase, and the like into the cytoplasm. From the RNA, DNA is transcribed by reverse transcriptase, and a full length double stranded DNA is produced. The DNA is imported into the nucleus of the host cell and integrated by integrase into the DNA of the host cell. The integrated DNA is converted to an mRNA by polymerase of the host cell, from which mRNA various proteins necessary for forming a virus are synthesized by HIV protease and the like, and a virus particle is finally formed, which then undergoes budding and its release.

[0007] These virus specific enzymes are considered to be essential for the growth of HIV. These enzymes are drawing attention as the target of the development of antiviral agents, and several anti-HIV agents have been already developed.

[0008] For example, zidovudine, didanosine, lamivudine and the like have been already on the market as reverse transcriptase inhibitors, and indinavir, nelfinavir and the like as protease inhibitors.

[0009] In addition, a multiple drug combination therapy concurrently using these pharmaceutical agents has been employed. For example, a combined use of two reverse transcriptase inhibitors (zidovudine and didanosine), and a combined use of three agents of reverse transcriptase inhibitors (zidovudine and lamivudine) and a protease inhibitor (nelfinavir) and the like have been clinically applied. Such multiple drug combination therapy is becoming a mainstream of AIDS therapy (see, e.g., Guidelines for the Use of Antiretroviral Agents in HIV-Infected Adults and Adlescent. August 13, 2001).

[0010] However, some of these pharmaceutical agents are known to cause side effects such as liver function failure, central nervous disorders (e.g., vertigo), and the like. In addition, acquisition of resistance to a pharmaceutical agent causes a problem. Even worse, emergence of an HIV that shows multiple drug resistance in a multiple drug combination therapy has been known.

[0011] Under the circumstances, a further development of a novel pharmaceutical agent, particularly a development of an anti-HIV agent based on a new mechanism, has been desired, wherein a development of an anti-HIV agent having an integrase inhibitory activity is expected, because an integrase characteristic of retrovirus is an essential enzyme for the growth of HIV.

[0012] Nevertheless, an effective integrase inhibitor has not been found as yet.

[0013] Known compounds comparatively similar to the anti-HIV agent of the present invention are described in the following.

[0014] WO02/0704865 describes the following compounds [A], [B] and the like as anti-HIV agents having an integrase inhibitory activity (see WO02/0704865 p. 118, Example I-62, p. 203, Example I-152).

[0015] In addition, WO02/36734 describes the following compound [C] and the like as anti-HIV agents having an integrase inhibitory activity (see WO02/36734, p. 106, Ex. 3).

[0016] Moreover, WO02/55079 describes the following compound [D] and the like as anti-HIV agents having an integrase inhibitory activity (see WO02/055079, p. 79, Ex. 1).

[0017] However, these publications do not include the 4-oxoquinoline compound disclosed in the present specification, or any description suggestive thereof.

[0018] The compounds comparatively similar to the compound of the present invention are described in the following.

[0019] US3,472,859 describes the following compound [E] and the like as antibacterial agents or antimicrobial agents (see US3,472,859, column 11, line 10).

[0020] In addition, JP-A-48-26772 describes the following compound [F] and the like as compounds having an antibacterial activity (see, e.g., JP-A-48-26772, p. 6, Example 9; KYUSHU KYORITSU UNIVERSITY, Memoirs Department of Engineering, No. 14, pp. 21-32, March 1990; Memoirs Kyushu Inst. Tech. (Eng.) No.14, pp. 13-16, 1984).

[0021] As dehydrogenase inhibitors, moreover, the following compound [G] and the like have been pharmacologically evaluated (see Journal of Medicinal Chemistry, table 1, vol. 15, No. 3, pp. 235-237, 1972).

[0022] In addition, JP-A-2002-534416 (patent family: WO00/40561, US6,248,739, EP1140850) describes the following compound [H] and the like as synthetic intermediates for compounds having an antiviral activity (see JP-A-2002-534416, p. 141, compound 60).

[0023] JP-A-2002-534417 (patent family: WO00/40563, US6,248,736, EP1140851) also describes the following compound [J] and the like as synthetic intermediates for compounds having an antiviral activity (see JP-A-2002-534417, p. 34, compound 18).

[0024] Moreover, WO01/98275 (patent family: US2001/103220) also describes the following compound [K] and the like as synthetic intermediates for compounds having an antiviral activity (see WO01/98275, p. 39, line 29).

[0025] Furthermore, JP-A-4-360872 (patent family: US5,985,894, EP498721B1) describes the following compound [L] and the like as compounds having an antagonistic action against anti-angiotensin II receptor (see JP-A-4-360872, p. 64, Table 1)).

[0026] US 5,217,972 discloses a certain class of quinolonecarboxylic acid derivatives and their use as antiviral agents.

[0027] From the findings based on the pharmacological researches and clinical results obtained so far, an anti-HIV agent is effective for the prophylaxis of the onset of AIDS and the treatment thereof, and particularly a compound having an integrase inhibitory action can provide an effective anti-HIV agent.

[0028] It is therefore an object of the present invention to provide a pharmaceutical agent having an anti-HIV action, particularly a pharmaceutical agent having an integrase inhibitory action.

[0029] The present inventors have conducted intensive studies in an attempt to find a compound having an anti-HIV action, particularly a compound having an integrase inhibitory action, and completed the present invention.

Experimental Examples

[0334] The following explains evaluation methods of the HIV integrase inhibitory activity of the compound of the present invention.

(i) Construction of recombinant integrase gene expression system
The 185th phenylalanine of HIV integrase full length gene (J. Virol., 67, 425-437 (1993)) was substituted by histidine and inserted into the restriction enzyme NdeI and XhoI sites of plasmid pET21a(+) (Novagen), whereby an integrase expression vector pET21a-IN-F185H was constructed.

(ii) Production and purification of integrase protein
Escherichia coli recombinant BL21 (DE3) transformed with plasmid pET21a-IN-F185H obtained in (i) was shake cultured at 30°C in a liquid medium containing ampicillin. When the culture reached the logarithmic growth phase, isopropyl-β-D-thiogalactopyranoside was added to promote expression of integrase gene. The culture was continued for 3 hrs to promote accumulation of the integrase protein. The recombinant E. coli was collected in pellets by centrifugal separation and preserved at -80°C.
The E. coli was suspended in Lysis buffer (20 mM HEPES (pH 7.5), 5 mM DTT, 10 mM CHAPS, 10% glycerol) containing 1M sodium chloride and subjected to repeat pressurization and depressurization for rupture, and centrifugal separation at 4°C, 40,000×g, 60 min to recover a water-soluble fraction (supernatant). This was diluted 10-fold with Lysis buffer free of sodium chloride, mixed with SP-Sepharose (Pharmacia Corporation) and stirred at 4°C for 60 min to allow absorption of integrase protein to the resin. The resin was washed with Lysis buffer containing 100 mM sodium chloride and the integrase protein was eluted with Lysis buffer containing 1M sodium chloride.
The eluted integrase protein solution was applied to a Superdex 75 (Pharmacia Corporation) column for gel filtration. The protein was eluted with Lysis buffer containing 1M sodium chloride.
The obtained fractions of the integrase protein were collected and preserved at -80°C.

(iii) Preparation of DNA solution
The following DNA synthesized by Greiner was dissolved in TE buffer (10 mM Tris-hydrochloric acid (pH 8.0), 1 mM EDTA) and mixed with donor DNA, target DNA, each complementary strand (+ and - strands) to 1 µM. The mixture was heated at 95°C for 5 min, 80°C for 10 min, 70°C for 10 min, 60°C for 10 min, 50°C for 10 min and 40°C for 10 min and preserved at 25°C to give a double stranded DNA, which was used for the test. Donor DNA (- strand having biotin attached to the 5' terminal) Donor + strand: 5'-Biotin-ACC CTT TTA GTC AGT GTG GAA AAT CTC TAG CA-3' (SEQ ID NO:1)
Donor - strand: 5'-ACT GCT AGA GAT TTT CCA CAC TGA CTA AAA G-3' (SEQ ID NO:2)
Target DNA (+, - strands both having digoxigenin added at 3' terminal)
Target + strand: 5'-TGA CCA AGG GCT AAT TCA CT-Dig-3' (SEQ ID NO:3)
Target - strand: 5'-AGT GAA TTA GCC CTT GGT CA-Dig-3' (SEQ ID NO:4)

(iv) Determination of enzyme (HIV integrase) inhibitory activity

[0335] The donor DNA was diluted with TE buffer to 10 nM, of which 50 µl was added to each well of streptavidin-coated microtiter plate (Roche) and allowed to adsorb at 37°C for 60 min. The DNA was washed with phosphate buffer (Dulbecco PBS, Sanko Junyaku Co., Ltd.) containing 0.1% Tween 20 and phosphate buffer. Then, a reaction mixture (70 µl) having the following composition, a test substance (10 µl) diluted with the reaction mixture and 100 µg/ml integrase protein (10 µl) were added to each well and reacted at 37°C for 60 min.

[0336] The, 50 nM target DNA (10 µl) was added, reacted at 37°C for 10 min and washed with phosphate buffer containing 0.1% Tween 20 to stop the reaction.

[0337] Then, 100 mU/ml peroxidase labeled anti-digoxigenin antibody solution (Roche, 100 µl) was added, and the mixture was reacted at 37°C for 60 min, followed by washing with phosphate buffer containing 0.1% Tween 20.

[0338] A peroxidase color solution (Bio Rad, 100 µl) was added and allowed to react at room temperature for 4 min. The color reaction was stopped by adding 1N sulfuric acid (100 µl). The absorbance at 450 nm was measured.

[0339] The HIV integrase inhibitory activity (IC₅₀) of the compound of the present invention was calculated from the inhibition rate according to the following formula. The results are shown in Tables 5, 6 and 7.

Evaluation of antiviral activity

[0340] The effect of combined use of the compound of the present invention with known anti-HIV agents can be determined as shown below.

[0341] For example, the effect of two-drug use of an existing nucleoside reverse transcriptase inhibitor (Zidovudine, Lamivudine, Tenofovir), a non-nucleoside reverse transcriptase inhibitor (Efavirenz) or a protease inhibitor (Indinavir, Nelfinavir) and a test substance A, and the like are evaluated in an acute infection system using HIV-1 IIIB-infected CEM-SS cells by the XTT method.

[0342] In addition, the effect of three-drug use of test substance A, Zidovudine and Lamivudine, or test substance A, Tenofovir and Lamivudine and the like is evaluated.

[0343] Prior to the combined use test, IC₅₀ and CC₅₀ of each pharmaceutical agent alone are determined. The effect of two-drug use is evaluated based on the combination of five concentrations of pharmaceutical agent A and nine concentrations of pharmaceutical agent B, which have been determined based on the above results. For three-drug use, high concentrations of pharmaceutical agent B and pharmaceutical agent C are mixed and the obtained concentrations are combined with the concentrations of pharmaceutical agent A for evaluation.

[0344] The experimental data of the test substance and pharmaceutical agent to be combined in the case of single use and combined use are analyzed by the programs of Prichard and Shipman MacSynergy II version 2.01 and Delta graph version 1.5d. A three dimensional plot is created at a 95% (or 68%, 99%) confidence level, from the percent inhibition at the concentration of each combined pharmaceutical agent, which is obtained from triplicate experiments, and the effect of combined use is evaluated based on the numerical values of µM²% calculated therefrom. The evaluation criteria are shown in the following.

definition of interaction	µM2%
highly synergistic	>100
slightly synergistic	+51 to +100
additive	+50 to -50
slightly antagonistic	-51 to -100
highly antagonistic	<-100
