Description

TECHNICAL FIELD

The present invention relates to a tetracyclic fused heterocyclic compound or a pharmaceutically acceptable salt thereof, which shows anti-hepatitis C virus (HCV) activity, particularly anti-HCV activity based on an RNA-dependent RNA polymerase inhibitory activity. In addition, the present invention relates to a hepatitis C virus polymerase inhibitor, an anti-hepatitis C virus agent and a therapeutic agent for hepatitis C containing said tetracyclic fused heterocyclic compound or a pharmaceutically acceptable salt thereof.

BACKGROUND ART

In 1989, a main causative virus of non-A non-B posttransfusion hepatitis was found and named hepatitis C virus (HCV). Since then, several types of hepatitis viruses have been found besides type A, type B and type C, wherein hepatitis caused by HCV is called hepatitis C.

The patients infected with HCV are considered to involve several percent of the world population, and the infection with HCV characteristically becomes chronic.

HCV is an envelope RNA virus, wherein the genome is a single strand plus-strand RNA, and belongs to the genus Hepacivirus of Flavivirus (from The International Committee on Taxonomy of Viruses, International Union of Microbiological Societies). Of the same hepatitis viruses, for example, hepatitis B virus (HBV), which is a DNA virus, is eliminated by the immune system and the infection with this virus ends in an acute infection except for neonates and infants having yet immature immunological competence. In contrast, HCV somehow avoids the immune system of the host due to an unknown mechanism. Once infected with this virus, even an adult having a mature immune system frequently develops persistent infection. When chronic hepatitis is associated with the persistent infection with HCV, it advances to cirrhosis or hepatic cancer in a high rate. Enucleation of tumor by operation does not help much, because the patient often develops recurrent hepatic cancer due to the sequela inflammation in non-cancerous parts. In addition, there is a report on the involvement of HCV infection in dermatosis such as chronic urticaria, lichen planus, cryoglobulinemic purpura and the like (The Japanese Journal of Dermatology, Vol. 111, No. 7, pages 1075-1081, 2001).

Thus, an effective therapeutic method of hepatitis C is desired. Apart from the symptomatic therapy to suppress inflammation with an anti-inflammatory agent, the development of a therapeutic agent that reduces HCV to a low level free from inflammation and that eradicates HCV has been strongly demanded.

At present, a treatment with interferon is the only effective method known for the eradication of HCV. However, interferon can eradicate the virus only in about one-third of the patient population. For the rest of the patients, it has no effect or provides only a temporary effect. In recent years, polyethylene glycolated interferon has been put to practical use, and enhanced effects and reduced side effects have been achieved. However, complete response rate still remains at a low level, and therefore, an anti-HCV drug to be used in the place of or concurrently with interferon is awaited in great expectation.

In recent years, Ribavirin (1-β-D-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide) has become commercially available as a therapeutic agent for hepatitis C, which is to be used concurrently with interferon. It enhances the efficacy of interferon but only to a low efficacy rate, and a different novel therapeutic agent for hepatitis C is desired.

Also, an attempt has been made to potentiate the immunocompetence of the patient with an interferon agonist, an interleukin-12 agonist and the like, thereby to eradicate the virus, but an effective pharmaceutical agent has not been found yet.

In addition, the inhibition of HCV growth, wherein HCV-specific protein is targeted, has been drawing attention these days.

The gene of HCV encodes a protein such as serine protease, RNA helicase, RNA-dependent RNA polymerase and the like. These proteins function as a specific protein essential for the growth of HCV.

One of the specific proteins, RNA-dependent RNA polymerase (hereinafter to be also briefly referred to as an HCV polymerase), is an enzyme essential for the growth of the virus. The gene replication of HCV having a plus-strand RNA gene is considered to involve synthesis of a complementary minus-strand RNA by the use of the plus-strand RNA as a template and using the obtained minus-strand RNA as a template, amplifying the plus-strand RNA. The portion called NS5B of a protein precursor, that HCV codes for, has been found to show an RNA-dependent RNA polymerase activity (EMBO J., Vol. 15, pages 12-22, 1996), and is considered to play a central role in the HCV gene replication.

Therefore, an HCV polymerase inhibitor can be a target in the development of an anti-HCV drug, and the development thereof is eagerly awaited. However, an effective HCV polymerase inhibitor has not been developed yet, like in other attempts to develop an anti-HCV drug based on other action mechanisms. As the situation stands, no pharmaceutical agent can treat hepatitis C satisfactorily.

The evaluation of the HCV polymerase inhibitory activity of the compound of the present invention is explained in the following. This polymerase is an enzyme coded for by the non-structural protein region called NS5B on the genome RNA of HCV (EMBO J., 15:12-22, 1996).

Experimental Example [I]

i) Preparation of Enzyme (HCV Polymerase)

Using, as a template, a cDNA clone corresponding to the full length genome RNA of HCV BK strain obtained from the blood of a patient with hepatitis C, a region encoding NS5B (J Virol 1991 March, 65(3), 1105-13, 544 amino acids after deletion of 47 amino acids on the C-terminal) was amplified by PCR. The objective gene was prepared by adding a 6 His tag {base pair encoding 6 continuous histidine (His)}to the 3′ end thereof and transformed to Escherichia coli. The Escherichia coli capable of producing the objective protein was cultured. The obtained cells were suspended in a buffer solution and crushed in a microfluidizer. The supernatant was obtained by centrifugation and applied to various column chromatographys {mono-S, Sephacryl S-200 (Pharmacia)}, inclusive of metal chelate chromatography, to give a standard enzyme product.

ii) Synthesis of Substrate RNA

Using a synthetic primer designed based on the sequence of HCV genomic 3′ untranslated region, a DNA fragment (148 bp) containing polyU and 3′X sequence was entirely synthesized and cloned into plasmid pBluescript SK II(+) (Stratagene). The cDNA encoding full length NS5B, which was prepared in i) above, was digested with restriction enzyme KpnI to give a cDNA fragment containing the nucleotide sequence of from the restriction enzyme cleavage site to the termination codon. This cDNA fragment was inserted into the upstream of 3′ untranslated region of the DNA in pBluescript SK II(+) and ligated. The about 450 bp inserted DNA sequence was used as a template in the preparation of substrate RNA. This plasmid was cleaved immediately after the 3′X sequence, linearized and purified by phenol-chloroform treatment and ethanol precipitation to give DNA.

RNA was synthesized (37° C., 3 hr) by run-off method using this purified DNA as a template, a promoter of pBluescript SK II(+), MEGAscript RNA synthesis kit (Ambion) and T7 RNA polymerase. DNase I was added and the mixture was incubated for 1 hr. The template DNA was removed by decomposition to give a crude RNA product. This crude product was treated with phenol-chloroform and purified by ethanol precipitation to give the objective substrate RNA.

This RNA was applied to formaldehyde denaturation agarose gel electrophoresis to confirm the quality thereof and preserved at −80° C.

iii) Assay of Enzyme (HCV Polymerase) Inhibitory Activity

A test substance (compound of the present invention) and a reaction mixture (30 μl) having the following composition were reacted at 25° C. for 90 min.

10% Trichloroacetic acid at 4° C. and 1% sodium pyrophosphate solution (150 μl) were added to this reaction mixture to stop the reaction. The reaction mixture was left standing in ice for 15 min to insolubilize RNA. This RNA was trapped on a glass filter (Whatman GF/C and the like) upon filtration by suction. This filter was washed with a solution containing 1% trichloroacetic acid and 0.1% sodium pyrophosphate, washed with 90% ethanol and dried. A liquid scintillation cocktail (Packard) was added and the radioactivity of RNA synthesized by the enzyme reaction was measured on a liquid scintillation counter.

The HCV polymerase inhibitory activity (IC₅₀) of the compound of the present invention was calculated from the values of radioactivity of the enzyme reaction with and without the test substance.

The results are shown in Tables 269-293.

As the compound of the present invention, preferred is a compound showing less than 1 μM of HCV polymerase inhibitory activity (IC₅₀), more preferred is a compound showing less than 0.1 μM of HCV polymerase inhibitory activity (IC₅₀), and still more preferred is a compound showing less than 0.01 μM of HCV polymerase inhibitory activity (IC₅₀).

Reaction mixture: HCV polymerase (0.5 μg/ml) obtained in i), substrate RNA (5 μg/ml) obtained in ii), ATP (50 μM), GTP (50 μM), CTP (50 M), UTP (2 μM), [5,6-³H]UTP (46 Ci/mmol (Amersham), 1 μCi) 20 mM Tris-HCl (pH 7.5), EDTA (1 mM), MgCl₂ (5 mM), NaCl (50 mM), DTT (1 mM), BSA (0.01%)

Experimental Example [II]

The test compound was dissolved in DMSO (dimethyl sulfoxide; final concentration 0.5%), and adjusted to a 10-fold concentration of the final concentration with a medium.

Replicon cells (Huh-5-2: manufactured by ReBLikon GmbH) were inoculated on a medium at 5×10³/90 μl/well in a 96-well plate.

The medium was changed to a 4% HSA (human serum albumin)-containing medium (90 μl) the next day, and 10 μl of the above-mentioned adjusted product at each concentration was added.

At 48 hr later, luciferase activity was measured with Steady-Glo (manufactured by PROMEGA). The inhibitory rate relative to the control group (0.5% DMSO addition group) was calculated and EC₅₀ value was determined by proportional calculation, based on the data of two points across 50%, with the concentration of the compound taken as logarithm. Composition of medium: Dulbecco's modified Eagle's medium (DMEM), 10% fetal bovine serum (FBS), 2 mM L-glutamine, 0.1 mM MEM non-essential amino acid, 100 U/ml penicillin, 0.1 mg/ml streptomycin

As in the test, one showing high replication inhibitory, or HCV polymerase inhibitory activity in the presence of a protein is one of the preferable embodiments.

As is evident from the above-mentioned results, the compound of the present invention shows a high inhibitory activity against HCV polymerase.

Therefore, the compound of the present invention can provide a pharmaceutical agent effective for the prophylaxis or treatment of hepatitis C, based on the anti-HCV effect afforded by the HCV polymerase inhibitory activity. When used concurrently with a different anti-HCV agent, such as interferon, and/or an anti-inflammatory agent and the like, it can provide a pharmaceutical agent more effective for the prophylaxis or treatment of hepatitis C. Its high inhibitory activity specific to HCV polymerase suggests the possibility of the compound being a pharmaceutical agent with slight side effects, which can be used safely for humans.
