The present invention relates to novel compounds possessing an antiviral activity, more particularly, polycyclic carbamoylpyridone derivatives having a HIV integrase inhibitory activity and a pharmaceutical composition, particularly an anti-HIV agent containing the same.
Among viruses, human immunodeficiency virus (hereafter, referred to as HIV), a kind of retrovirus, is known to cause acquired immunodeficiency syndrome (hereafter, referred to as AIDS). The therapeutic agent for AIDS is mainly selected from a group of reverse transcriptase inhibitors (e.g., AZT, 3TC) and protease inhibitors (e.g., Indinavir), 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, currently, a combination therapy is reported to be efficient in treatment for AIDS because of the frequent emergence of the resistant mutant. Two kinds of reverse transcriptase inhibitors and protease inhibitors are clinically used as an anti-HIV agent; however agents having the same mechanism of action often exhibit cross-resistance or only an additional activity. Therefore, development of anti-HIV agents having the other mechanism of action is desired.
Under the circumstances above, an integrase inhibitor has been focused on as an anti-HIV agent having a novel mechanism of action (Ref: Patent Documents 1 and 2). As an anti-HIV agent having such a mechanism of action, known are carbamoyl-substituted hydroxypyrimidinone derivative (Ref: Patent Documents 3 and 4) and carbamoyl-substituted hydroxypyrrolidione derivative (Ref: Patent Document 5). Further, a patent application concerning carbamoyl-substituted hydroxypyridone derivative has been filed (Ref: Patent Document 6, Example 8).
Other known carbamoylpyridone derivatives include 5-alkoxypyridine-3-carboxamide derivatives and γ-pyrone-3-carboxamide derivatives, which are a plant growth inhibitor or herbicide (Ref: Patent Documents 7-9).
Other HIV integrase inhibitors include N-containing condensed cyclic compounds (Ref: Patent Document 10).
In addition, the present applicant filed a dicyclic carbamoylpyridone derivative as a HIV integrase inhibiting agent (Ref: Patent Document 11).
Under such the circumstances, the development of a novel integrase inhibitor has been desired.
The present inventors intensively studied to find that a novel polycyclic carbamoylpyridone derivative possesses a potent HIV integrase inhibitory activity. Moreover, the present inventors have discovered that a compound of the present compound and a pharmaceutical composition containing the same are useful as an antiviral agent (e.g. antiretroviral agent, anti-HIV agent, anti-HTLV-1 (Human T cell leukemia virus type 1) agent, anti-FIV (Feline immunodeficiency virus) agent, anti-SIV (Simian immunodeficiency virus) agent), especially an anti-HIV agent, an anti-AIDS agent, or a therapeutic for associated diseases, to accomplish the present invention shown below.

The HIV integrase inhibitory activity was investigated based on the following assay method.
(1) Preparation of DNA Solution
By the same method as that described in Experimental Example 1 of WO 2004/024693, a substrate DNA solution (2 μmol/μl) and a target DNA solution (5 μmol/μl) were prepared. After each target DNA solution was once boiled, a temperature was slowly lowered to anneal complementary chains, which was used. Each sequence of a substrate DNA and a target DNA is as described in the same Experimental Example.
(2) Measurement of Inhibition Rate (IC50 Value)
Streptavidin (manufactured by Vector Laboratories) was dissolved in a 0.1 M carbonate buffer solution (composition: 90 mM Na2CO3, 10 mM NaHCO3) to a concentration of 40 μg/ml. Each 50 μl of this solution was added to a well of an immunoplate (manufactured by NUNC), and this is allowed to stand at 4° C. overnight to adsorb. Then, each well was washed with a phosphate buffer (composition: 13.7 mM NaCl, 0.27 mM KCl, 0.43 mM Na2HPO4, 0.14 mM KH2PO4) two times, and 300 μl of a phosphate buffer containing 1% skim milk was added to block it for 30 minutes. Further, each well was washed with a phosphate buffer two times, 50 ml of a substrate DNA solution (2 μmol/μl) was added to adsorb at room temperature for 30 minutes while shaking, and this was washed with a phosphate buffer two times and, then, distilled water once.
Then, to each well prepared as described above were added 12 μl of a buffer (composition: 150 mM MOPS (pH7.2), 75 mM MnCl2, 50 mM 2-mercaptoethanol, 25% glycerol, 500 μg/ml bovine serum albumin-fraction V), and 51 μl of a reaction solution prepared from 39 ml of distilled water. Then, 9 μl of an integrase solution (30 μmol) was added, and the mixture was mixed well. To a well as a negative control (NC) was added 9 μl of a diluting solution (composition: 20 mM MOPS (pH7.2), 400 mM potassium glutamete, 1 mM EDTA, 0.1% NP-40, 20% glycerol, 1 mM DTT, 4 M urea), and this was mixed well using a plate mixer.
After the plate was incubated at 30° C. for 60 minutes, the reaction solution was discarded, followed by washing with 250 μl of a washing buffer (composition: 150 mM MOPS (pH7.2), 50 mM 2-mercaptoethanol, 25% glycerol, 500 μg/ml bovine serum albumin-fraction V) three times.
Then, to each well were added 12 μl of a buffer (composition: 150 mM MOPS (pH7.2), 75 mM MgCl2, 50 mM 2-mercaptoethanol, 25% glycerol, 500 μg/ml bovine serum albumin-fraction V), and 53 μl of a reaction solution prepared from 41 μl of distilled water. Further, 6 μl of a solution of a test compound in DMSO was added to each well, and 6 μl of DMSO was added to a well as a positive control (PC), followed by mixing well using a plate mixer. After the plate was incubated at 30° C. for 30 minutes, 11 of a target DNA (5 μmol/μl) was added, and this was mixed well using a plate mixer.
After each plate was incubated at 30° C. for 10 minutes, the reaction solution was discarded, followed by washing with a phosphate buffer two times. Then, an anti-digoxigenin antibody labeled with alkaline phosphatase (sheep Fab fragment: manufactured by Boehringer) was diluted 2000-fold with an antibody diluting solution, 100 μl of the diluent was added to bind at 30° C. for 1 hour, and this was washed successively with a phosphate buffer containing 0.05% Tween20 two times, and a phosphate buffer once. Then, 150 μl of an alkaline phosphatase coloring buffer (composition: 10 mM paranitrophenyl phosphate (manufactured by Vector Laboratories), 5 mM MgCl2, 100 mM NaCl, 100 mM Tris-HCl (pH 9.5)) was added to react at 30° C. for 2 hours, 50 μl of a 1N NaOH solution was added to stop the reaction, an absorbance (OD405 nm) of each well was measured, and an inhibition rate (IC50) was obtained according to the following calculation equation.
Inhibition rate (%)=100[1−{(C abs.−NC abs.)/(PC abs.−NC abs.)}]
C abs.; absorbance of well of compound
NC abs.: absorbance of NC
PC abs.: absorbance of PC
