## Background
TECHNICAL FIELD
The present invention relates to a benzodiazepine compound and a pharmaceutical composition.
BACKGROUND ART
Atrial fibrillation (hereinafter referred to as “AF”) is the most frequently observed type of arrhythmia in clinical examinations. Although not a lethal arrhythmia, AF causes cardiogenic cerebral embolism, and is therefore recognized as an arrhythmia that greatly affects vital prognoses and QOL. It is known that the onset of AF increases with age, and that repeated AF strokes lead to chronic (serious) AF (The Journal of American Medical Association, 285, 2370-2375 (2001) and Circulation, 114, 119-123 (2006)).
To prevent chronic AF, which causes difficulty in restoring sinus rhythm and increases the risk of cardiogenic cerebral embolism, early defibrillation and subsequent prevention of recurrence (maintenance of the sinus rhythm) are required. Antiarrhythmic drugs (classes I and III) are most commonly used as pharmacotherapy, but these drugs achieve insufficient therapeutic effects, while causing serious side effects such as a proarrhythmic effect (Am. J. Cardiol., 72, B44-B49 (1993)).
The onset of AF is triggered by atrial premature contraction with underlining causes such as intra-atrial conduction delay, shortening and heterogeneity of the atrial refractory period (Nature Reviews DRUG DISCOVERY 4, 899-910 (2005)). It is known that the prolongation of refractory period of atrial muscle can terminate AF (defibrillation) or prevent the occurence of AF. The action potential duration of the mammalian cardiac muscle is predominantly determined by voltage-dependent K+ channels. Inhibition of the K+ channel prolongs myocardial action potential duration, which results in prolongation of the refractory period (Nature Reviews DRUG DISCOVERY 5, 1034-49 (2006)). The action mechanism of class III antiarrhythmic drugs (e.g., Dofetilide) is to inhibit rapid delayed rectifier K+ current (IKr), K+ current encoded by HERG. However, since IKr is present in both the atria and ventricles, such drugs might cause ventricular arrhythmias, such as torsades de pointes (Trends Pharmacol. soc., 22, 240-246 (2001)).
Ultra-rapid delayed rectifier K+ current (IKur), K+ current encoded by Kv1.5, has been identified as K+ channel that is specifically expressed only in human atria (Cric. Res., 73, 1061-1076 (1993), J. Physiol., 491, 31-50 (1996) and Cric. Res., 80, 572-579 (1997)). Muscarine potassium current (IKACh) encoded by two genes called GIRK1 and GIRK4 is known as a K+ channel specifically expressed in human atria (Nature 374, 135-141 (1995)). Accordingly, a pharmacologically acceptable substance that selectively blocks the IKur current (the Kv1.5 channel) or the IKAch current (GIRK1/4 channel) can act selectively on the atrial muscle and is considered effective to exclude the proarrhythmic effect caused by prolonged action potential duration of the ventricular muscle.
DISCLOSURE OF THE INVENTION
The present inventors conducted extensive research to develop a compound that blocks the IKur current (Kv1.5 channel) and/or the IKAch current (GIRK1/4 channel) potently and more selectively than other K+ channels.

Pharmacological Test 1

(1) Production of Human Kv1.5-Expressing CHO-K1 Cell Lines
CHO-K1 cell lines stably expressing human Kv1.5 channels were prepared in the following manner.
Full-length human Kv1.5 cDNA was cloned from a human heart cDNA library (produced by Stratagene). The obtained human Kv1.5 sequence corresponds to the sequence described in FASEB J. 5, 331-337 (1991).
The obtained human Kv1.5 cDNA was inserted into a plasmid encoding a CMV promoter and a G418 resistance marker to produce a Kv1.5 expression vector. The human Kv1.5 expression vector was transfected into CHO-K1 cells by the lipofectamine method. After culturing the cells in an F-12 medium (produced by Invitrogen Corp.) containing 10% FBS (produced by Invitrogen Corp.) for 3 or 4 days, the medium was replaced with a FBS-containing F-12 medium that included 1,000 μg/ml of G418 (produced by Invitrogen Corp.), and single colonies were isolated. The amount of Kv1.5 channel expression in the single colonies was quantified at the mRNA level by RT-PCR and then quantified at the protein level by western blotting. Finally, the expressed current was analyzed by patch clamp method. Cell lines expressing a current of 200 pA or more per cell were selected as channel-expressing cell lines for activity measurement by patch clamp method.
(2) Production of CHO Cell Line Expressing Human GIRK1/4
CHO cell lines stably expressing human GIRK1/4 channels were prepared in the following manner.
Full-length human GIRK1 cDNA was cloned from HuH cell- and HeLa cell-derived cDNA libraries. Full-length GIRK4 cDNA was amplified from a human heart cDNA library (produced by Clontech Laboratories, Inc.) by PCR using synthetic primers shown in Table 1, and cloned into the Eco-RI restriction enzyme site of pCR-Blunt (produced by Invitrogen Corporation) or into the HincII site of pUC118 (produced by Takara Bio, Inc.).

The obtained human GIRK1 and GIRK4 cDNA sequences correspond to known sequences (NCBI database: GIRK1 (NM—002239) and GIRK4 (NM—000890) respectively). The obtained GIRK1 and GIRK4 cDNA sequences were cloned into the Eco-RI restriction enzyme site of pCR-Blunt (available from Invitrogen Corporation) or into the HincII site of pUC118 (available from Takara Bio, Inc.). A GIRK4 expression vector was constructed by insertion into the BamHI-XhoI site of pcDNA5/FRT. A GIRK1 expression vector was constructed by insertion into the KpnI-XhoI site of pcDNA3. 1 (+) or pCAG_neo. FLP-IN-CHO cells (produced by Invitrogen Corporation) were transfected with human GIRK1 and GIRK4 expression vectors by using Lipofectamine 2000 (produced by Invitrogen Corporation) according to the protocol enclosed with the reagent or using an electronic induction method (“Nucleofector Kit-T”, produced by Amaxa). First, the cells transfected with the GIRK4 expression vector were cultured in a 10% serum-containing F12 medium (produced by Sigma) supplemented with 600 μg/ml of hygromycin in an incubator with 5% carbon dioxide at 37° C. Then the cells expressing GIRK4 were transfected with the GIRK1 expression vector and were cultured in 10% serum-containing F12 medium supplemented with 350 μg/ml of G418 and 600 μg/ml of hygromycin in an incubator with 5% carbon dioxide at 37° C. to select GIRK1/4 expressing cell lines. Cell populations whose growth was observed after about 2 weeks were isolated using cloning rings, and the obtained single colonies were proliferated. RNA was extracted from single colonies, and single-stranded cDNA was synthesized by a cDNA synthesis kit (produced by Invitrogen Corporation), and the amount of expression was quantified at the mRNA level by real-time PCR (Applied Biosystems, Ltd.). Finally, the expressed current was analyzed by patch clamp method described below. The cell lines expressing a current of 500 pA or more per cell were selected as channel-expressing cell lines for activity measurement by patch clamping method.
(3) Measurement of Ion Channel Current by Patch Clamp Method (Human Kv1.5-Expressing CHO-K1 Cell Line)
An experiment was carried out using a patch clamp setup at room temperature (20 to 26° C.). A perfusion chamber having a diameter of 20 nun (flow rate: about 5 ml/min) was mounted on the stage of a phase-contrast inverted microscope (produced by Nikon Corporation) placed on a vibration isolated table. A poly-L-lysine (produced by Sigma) -coated coverslip (diameter: 15 mm, produced by Matsunami Glass Ind., Ltd.) on which human Kv1.5-expressing cells were cultured was placed in the perfusion chamber.
Depolarizing stimulation pulses were applied and ionic current was recorded by using a patch clamp amplifier (EPC-7 or EPC-7 PLUS, produced by HEKA) and a personal computer (manufactured by IBM Corp.) in which software for data acquisition and analysis of ion channel current (PULSE 8.77, produced by HEKA) was installed. The current was measured in the whole-cell configuration of the patch-clamp technique. The tip (resistance: 2 to 4 MΩ) of a borosilicate glass pipette (produced by Sutter Instrument Co.) was gently placed on the cell membrane by using a three-dimensional mechanical micromanipulator (produced by Shoshin EM Corporation). Weak suction resulted in giga seal formation (the pipette resistance increased to more than 1 GΩ). Subsequently, stronger suction was applied to break the cell membrane. The capacitative current derived from the cell membrane was corrected using a patch clamp amplifier. Subsequently, the series resistance (Rs) between the pipette and the interior of the cell was measured and corrected.

(5) Measurement of Human Kv1.5 Current
While the membrane potential was holded at −80 mV, depolarizing pulses (−80 mV for 0.05 seconds→+40 mV for 0.2 seconds→−40 mV for 0.2 seconds→−80 mV for 0.05 seconds) were applied at a stimulation frequency of 1 Hz to measure Kv1.5 channel current. More specifically, first, while perfusing an extracellular solution containing 0.1% DMSO and holding the membrane potential at −80 mV, depolarizing pulses were applied. The current obtained during the pulse application was recorded as a current in the absence of the test compounds. Subsequently, while perfusing an extracellular solution containing 0.1 μM of a test compound and holding the membrane potential at −80 mV, depolarizing pulses were applied. After the inhibitory effect of the test compound had been stabilized, the current was recorded. The same procedure was repeated using an extracellular solution containing 1 μl of the test compound and then using an extracellular solution containing 10 μM of the test compound. The current obtained using the solution containing the test compound at each concentration was recorded.
The data was analyzed by using the step end current recorded during the +40 mV depolarizing stimulation. The “step end current” refers to the average current flowing for a period of 195 to 199 milliseconds from the start of the +40 mV depolarizing pulse stimulation.
Using the step end current in the presence of the test compound and the step end current in the absence of the test compound, the relative current in the solution containing the test compound at each concentration was calculated according to the following formula:

Relative current=(Step end current in the presence of the test compound)/(Step end current in the absence of the test compound)

(6) Measurement of Human GIRK1/4 Current
While the membrane potential was holded at −80 mV, hyperpolarizing pulses (−80 mV for 0.05 seconds→=120 mV for 0.2 seconds→=80 mV for 0.05 seconds) were applied at a stimulation frequency of 1 Hz to measure GIRK1/4 channel current. More specifically, first, while perfusing an extracellular solution containing 0.1% DMSO and maintaining the membrane potential at −80 mV, hyperpolarizing pulses were applied. The current obtained during the pulse application was recorded as the current in the absence of the test compounds. Subsequently, while perfusing an extracellular solution containing 0.1 μM of a test compound and maintaining the membrane potential at −80 mV, hyperpolarizing pulses were applied. After the inhibitory effect of the test compound had been stabilized, the current was recorded. The same procedure was repeated using an extracellular solution containing 1 μM of the test compound and then using an extracellular solution containing 10 μM of the test compound. The current obtained using the solution containing the test compound at each concentration were recorded.
The data was analyzed by using the step end current recorded during the −120 mV depolarizing stimulation. The “step end current” refers to the average current flowing for a period of 195 to 199 milliseconds from the start of the −120 mV depolarizing pulse stimulation.
Using the step end current in the presence of the test compound and the step end current in the absence of the test compound, the relative current in the solution containing the test compound at each concentration was calculated according to the following formula:

Relative current=(Step end current in the presence of the test compound)/(Step end current in the absence of the test compound)

(7) Calculation of Inhibitory Activity on Kv1.5 Channel Ionic Current and GIRK1/4 Channel Current

The concentration for 50% inhibition of Kv1.5 channel current or GIRK1/4 channel current (IC50 value) was calculated according to the following nonlinear regression equation:

Relative current=1/(1+[Concentration of the compound]/IC50)nH wherein nH is the Hill coefficient.
