Description

TECHNICAL FIELD

The present invention relates to a novel compound having an antiviral activity, in detail heteroaromatic derivatives having an inhibitory activity against HIV integrase, a pharmaceutical composition containing the same, especially an anti-HIV agent and a process for preparing the same.

BACKGROUND ART

Among viruses, human immunodeficiency virus (HIV), a kind of retrovirus, is known to cause acquired immunodeficiency syndrome (AIDS). The therapeutic agent for AIDS is mainly selected from the group of reverse transcriptase inhibitors (e.g., AZT, 3TC, and the like) and protease inhibitors (e.g., Indinavir and the like), but they are proved to be accompanied by side effects such as nephropathy and the emergence of resistant viruses. Thus, the development of anti-HIV agents having the other mechanism of action has been desired.

On the other hand, a combination therapy is reported to be efficient in treatment for acquired immunodeficiency syndrome because of the frequency emergency of the resistant mutant in Balzarini, J. et al, Proc. Natl. Acad. Sci. USA 1996, 93, p13152-13157. Reverse transcriptase inhibitors and protease inhibitors are clinically used as an anti-HIV agent but agents having the same mechanism of action often exhibit cross resistance or only an additional activity. Therefore, anti-HIV agents having the other mechanism of action are desired.

Under the above circumstance, the research has been focused on integrase, which is an enzyme relating to the site-specific recombination or insertion of viral DNA into chromosomes in animal cells, and the research for anti-HIV agents based on the enzyme inhibitory activity has been performed; (1) KOURILSKY P et al., Proc. Natl. Acad. Sci. USA 61 (3), 1013-1020 (1968); (2) F Barin et al., J. VIROL. METHODS (NETHERLANDS), 17/1-2(55-61) (1987); (3) Fesen. M R, Proc. Natl. Acad. Sci. USA 90: 2399, (1993); (4) DeNoon, D J, CDC AIDS Weekly Pagination:P2 (1990).

On the other hand, a gene therapy has been applied to thirteen hereditary diseases such as adenosine deaminase deficiency, familial hypercholesterolemia, haemophilia and the like, and recently extended to rheumatics, cancer, infectious diseases such as HIV and the like. Namely, the number of diseases as an object of a gene therapy is increasing year by year. The gene therapies have been applied on more than three thousands patients in the world, especially in the U.S.A. Several methods for transfections of genes have been developed such as a lipofectin method and a transfection with an adenovirus vector, an adeno-associated virus vector, and the like. Over fifty percents of the gene therapies are performed by using a retrovirus vector prepared from MLV (Moloney murine leukemia virus, Mo-MLV, MMLV). Though each method has merits and demerits, a retrovirus vector is expected to stably express the gene for a long term without disappearance of the gene by cell divisions because it is inserted into host cells. However, the clinically used retrovirus vector derived from MLV can infect only proliferating cells because it is not able to actively transfer to the nucleus. Therefore, the retrovirus vector derived from HIV can overcome the above problem, which is being researched.

The problems accompanied by these retrovirus vectors include 1) the emergence of self-replicating viruses by mutation or transformation with endogenous virus, 2) cytotocisity, 3) oncogenicity and the like. Therefore, it is important to solve the problems accompanied by these retrovirus vectors and various types of the improved vectors are studied. (Takashi Yoshida, The Japanese Association of Gene, Handbook of the development of the gene therapy, N.T.S., 1999).

Some integrase inhibitors have recently been reported, for example, peptide derivatives described in U.S. Pat. No. 5,578,573, tetrahydronaphthyl derivatives described in GB 2306476A, and acrydone derivatives described in WO 97/38999.

Additionally, in Kihm. Geterotsikl. Soedin. 1973, (11), 1519, the following 2-hydroxy-4-oxo-2-butenoic acid derivatives substituted with indolyl at the 4-position are described without showing any therapeutic activity.

Gardner, T. S. reported, in J. Org. Chem. 1961, (26), 1514, the following 2-hydroxy-4-oxo-2-butenoic acid esters substituted with heteroaryl at the 4-position, but their therapeutic activity is not described therein.

It is described in JP-A 61-134346 that the following 2-hydroxy-4-oxo-2-butenoic acid derivatives substituted with heteroaryl at the 4-position are useful as an antiulcer agent.

Ferles, M. Collect. Czech. Chem. Commun., 1990, 55, p1228-1233 and Barleunga, J. Synthesis 1996, 1, p133-140 disclose the following heteroaromatic derivatives having 1-hydroxy-3-oxo-propenylene group are described without any therapeutic activity.

Moreover, in U.S. Pat. No. 5,475,109, dioxobutanoic acid derivatives substituted with non-aromatic heterocycles are described to be useful as an anti influenza viral agent, whose mechanism of the action is the inhibition of cap-dependent endonuclease.

1-(5-Phenylaminotriazol-3-yl)-3-hydroxy-(thiophen-2-yl)-propenone, 1-[5-(4-tolylamino)triazol-3-yl]-3-hydroxy-(thiophen-2-yl)-propenone and the like are described in Indian. Journal of Chemistry Vol. 30B, March 1991, pp. 313-319, but their therapeutic activity is not described.

(3) To a solution of 2-acetyl-1-tert-butoylcarbonylpyrrole (313.7 mg, 1.5 mmol) in THF (10 ml) was added dropwise under −65° C., a solution of lithiumbistrimethylsilylamide in THF (1 M solution, 2 ml, 2 mmol). Subsequently, the reaction mixture was gradually warmed up to 0° C., cooled down to −70° C. again and mixed dropwise with a solution of 5-(4-fluorobenzyl)-furan carboxylic acid chloride (358 mg, 1.5 mmol) in THF (5 ml). The reaction mixture was gradually warmed up to room temperature and stirred for 30 minutes. The reaction solution was poured into an excess amount of ammonium chloride aqueous solution, extracted with ethylacetate, washed with brine and dried. The solvent was evaporated. To the obtained yellow oil was added trifluoroacetic acid (2 ml) and stirred for 30 minutes at room temperature. Trifluoroacetic acid was evaporated under reduced pressure. The residue was extracted with ethylacetate, washed with aqueous sodium hydrogencarbonate, washed with brine and dried. The solvent was evaporated. The obtained residue was recrystallized from n-hexane-isopropylether to give the titled compound (200 mg) as a yellow crystal. Yield 43%.

(2) Calculations of the percent inhibitions (the IC 50 values of test compounds)

Streptavidin, obtained from Vector Laboratories, was dissolved in 0.1M carbonate buffer (composition: 90 mM Na 2 CO 3 , 10 mM NaHCO 3 ) at concentration of 40 μg/ml. After coating each well of microtiter plates (obtained from NUNC) with 50 μl of the above solution at 4° C. over night, each well was washed twice with PBS (composition: 13.7 mM NaCl, 0.27 mM KCl, 0.43 mM Na 2 HPO 4 , 0.14 mM KH 2 PO 4 ) and blocked with 300 μl of 1% skim milk in PBS for 30 min. Additionally, each well was washed twice with PBS and added 50 μl of substrate DNA solution (2 pmol/μl). The microtiter plates were kept at room temperature for 30 min. Then, each well was washed twice with PBS and once with H 2 O.

Subsequently, in the each well prepared above were added 45 μl of the reaction buffer prepared from 12 μl of the buffer (composition: 150 mM MOPS (pH 7.2), 75 mM MnCl 3 , 50 mM 2-mercaptethanol, 25% glycerol, 500 μg/ml bovine serum albumin-fraction V), 1 μl of target DNA (5 pmol/μl), and 32 μl of the distilled water. Additionally, 6 μl of either a test compound in DMSO or DMSO for positive control (PC) was mixed with the above reaction buffer, then 9 μof an integrase solutions (30 pmol) was added and mixed well. In the well of negative control (NC) was added 9 μl of the integrase dilution buffer (composition: 20 mM MOPS (pH7.2) 400 mM potassium glutamate, 1 mM EDTA, 0.1% NP-40, 20% glycerol, 1 mM DTT, 4M urea).

The microtiter plates were incubated at 30° C. for 1 hour. The reaction solution was removed and each well was washed twice with PBS. Subsequently, each well of the microtiter plates was filled with 100 μl of anti-digoxigenin antibody labeled with alkaline phosphatase (Sheep Fab fragment: obtained from Boehringer) and incubated at 30° C. for 1 hour. Then, each well was washed twice with 0.05% Tween20 in PBS and once with PBS. Next, 150 μl of the Alkaline phosphatase reaction buffer (composition: 10 mM p-Nitrophenylphosphate (obtained from Vector Laboratories), 5 mM MgCl 2 , 100 mM NaCl, 100 mM Tris-HCl (pH 9.5)) was added in each well. The microtiter plates were incubated at 30° C. for 2 hours and the reaction was terminated by the addition of 50 μl of 1N NaOH solution. The optical density (OD) at 405 nm of each well was measured and the percent inhibition was determined by the following expression.

The percent inhibition (%)=100[1-{(C abs.-NC abs.)/(PC abs.-NC abs.)}]

C abs.; the OD of the well of the compounds

NC abs.; the OD of the negative control (NC)

PC abs.; the OD of the positive control (PC)

When the percent inhibition (%) is X% at the concentration of x μg/ml and the percent inhibition (%) is Y% at the concentration of y μg/ml, one of which is more than 50% and the other is less than 50%, IC 50 can be determined by the following expression.

IC 50 (μg/ml)= x -{( X -50)( x - y )/( X - Y )}

Therefore the present compound can inhibit not only an integrase of a HIV-1, but also that of an retrovirus such as HIV-2 (Human immunodeficiency virus type 2), HTLV-1 (Human T cell leukemia virus type 1), FIV (Feline immunodeficiency virus), SIV (Simian immunodeficiency virus) and suppress a replication thereof.

Therefore, the present compound, the tautomer, the prodrug, the pharmaceutically acceptable salt or the hydrate thereof, and the pharmaceutical composition containing them are useful as an antiviral agent, an antiretroviral agent, an anti-HIV agent, an anti-HTLV-1 agent, an anti-SIV agent, an anti-FIV agent.

Moreover, the present compound, which inhibits are integrase of a virus especially, Lentivirus), can be used for the gene therapy.

The process for producing the present compound and the intermediate thereof is useful for preparing an integrase inhibitor, an antiviral agent, an antiretroviral agent, an anti-HIV agent, as anti-HTLV-1 agent, an anti-SIV agent, an anti-FIV agent and the like. Whereas a peptide protease inhibitor is very expensive, difficult to prepare continually, therefore, difficult to apply to a treatment for HIV infectious disease in the developing country, the present process enables to produce the present compound economically, to provide the present compound continually, and to apply the present compound to a treatment for HIV infectious disease in the developing country.
