DESCRIPTION

Title of the Invention: HETEROCYCLIC COMPOUND

Technical Field

[0001]

The present invention relates to a heterocyclic compound having a calcium/calmodulin-dependent protein kinase II

(sometimes to be abbreviated as "CaMKII" in the present specification) inhibitory action, which is expected to be useful as an agent for the prophylaxis or treatment of cardiac diseases (particularly catecholaminergic polymorphic

ventricular tachycardia, postoperative atrial fibrillation, heart failure, fatal arrhythmia) and the like.

[0002]

(Background of the Invention)

Cardiac diseases include heart failure, arrhythmia, myocardial infarction, angina, valvular heart disease and the like, and they are high-mortality diseases. In treatment of cardiac diseases with a drug, the symptoms are improved by control of each risk factor and symptomatic therapy. However, the satisfaction with treatment remains low level, and there is now no definitive therapy.

Calcium-calmodulin complex binds to Ca ²⁺ /calmodulin- dependent protein kinase (CaMK) included in serine/threonine protein kinase, and activates the kinase. The CaMK family includes CaMKII, and four isoforms (α, β, γ and δ) exist as CaMKII. CaMKII a and CaMKII β are expressed mainly in cerebral tissue, and CaMKII γ and CaMKII δ are expressed in many tissues including heart. CaMKII is activated by amino acid- modification due to oxidative stress or hyperglycemia, in addition to the binding of calcium-calmodulin complex. CaMKII regulates cell functions by phosphorylation of a transcription factor which is a substrate, a protein that plays a function in organelle uptake/excretion of Ca ²⁺ , a protein that regulates contract and relax of muscles, a channel that regulates an intracellular ion concentration, and the like, due to its kinase activation.

Some documents suggest that CaMKII plays a harmful role in progress of cardiac disease conditions. Expression and activity of CaMKII are increased in heart of human patient or animal with heart failure (Non-Patent Documents 1-4) . In transgenic mouse overexpressing CaMKII δ in heart, onsets of cardiac hypertrophy and heart failure are reported (Non-Patent Document 4) . By studies using an inhibitor by a

pharmacological method, and studies using a gene deletion by genetic method, protecting effects on heart failure, cardiac hypertrophy, myocardial infarction and arrhythmia by an inhibition of CaMKII and an overexpression of CaMKII inhibitory protein are reported in mouse (Non-Patent Documents 5-7) . For catecholaminergic polymorphic ventricular tachycardia, improving effects on disease conditions by CaMKII inhibitor in mutant ryanodine knock-in mouse (RyR2 ^R4496c+/~ mouse) are reported (Non-Patent Document 8) . These findings suggest availabilities of CaMKII inhibitors in the prophylaxis and/or treatment of cardiac diseases including heart failure, cardiac hypertrophy, myocardial infarction and cardiac arrhythmia.

Recently, CaMKII exacerbating action on growth or metastasis of a certain type of cancer is suggested (Non-Patent Document 9) . In addition, therapeutic effect on acute renal failure, intimal hypertrophy, hepatic fibrosis, stroke, pain, rheumatoid arthritis and the like by CaMKII inhibition are also indicated (Non-Patent Documents 10-15) .

However, genetic methods achieve only deficiency of protein or overexpression of inhibitory protein, and they are different from a mechanism which inhibits temporarily kinase activity, and therefore, effects by kinase inhibitor cannot be always expected. In addition, inhibitors which have been already reported are not suitable for application as a

medicament for a CaMKII selective inhibitor, because they have a low kinase selectivity to CaMKII, or they are not suitable for oral administration or chronic administration.

(i) Objective

In vitro CaMKII5 inhibitory activity was evaluated by an enzyme assay.

(ii) Methods

10 Human CaMKII enzyme inhibition assay

Kinase assay for CaMKIIs was performed using the

radiometric assay. Human full-length CaMKII5 (Cat# 02-111) was obtained from Carna Biosciences (Kobe, Japan) .

Enzyme reactions were performed in 25 mM HEPES, pH 7.5,

15 with 5 mM magnesium chloride, 1 mM calcium chloride, 10 μg/mL

Calmodulin, 2 mM DTT, 0.01% Tween20 and 500 nM ATP (0.2

Ci/well of [γ-33Ρ] ATP) containing 0.5 nM CaMKII5 and 0.1 μΜ autophosphorylation peptide (KKALRRQETVDAL) (Toray Research

Center) .

20 After incubating the enzyme, peptide, and compounds for 5 min, kinase reactions were initiated by adding ATP, followed by incubation for 60 min at room temperature in a total volume of 50 μΐ.. The reactions were terminated by the addition of 10% trichloroacetic acid (final concentration) . The [γ-33Ρ]-

25 phosphorylated proteins were filtered in a Harvest Plate (Merck Millipore) with a Cell Harvester (PerkinElmer) and then free

[γ-33Ρ] ATP was washed out with 3% phosphoric acid. The plates were dried, followed by the addition of 40 μΐ of MicroScintO ( PerkinElmer) . The radioactivity was counted by a TopCount scintillation counter (PerkinElmer) . The signals of the reaction without enzyme were defined as 100% inhibitory activity and those of the reaction without inhibitors as 0% inhibitory activity. In vitro CaMKII5 inhibitory activity was evaluated by % inhibitory activity of 3 μΜ compound

concentration .

(iii) Methods

Time-resolved fluorescence resonance energy transfer (TR-FRET) assay

All assays were conducted using 384-well, white, flat- bottomed plates (product # 784075, Greiner Bio-One,

Frickenhausen, Germany) in kinase assay buffer, which consists of 50 mM HEPES pH 7.6, 10 mM MgCl2, 1 mM EGTA, 0.01% Brig-35, 0.1 mM DTT) . The fluorescent probe ligand was added at a final concentration of 300 nM to solutions containing 0.21 nM Tb- anti-GST Ab, 1 mM CaCl ₂ , 10 μg/mL calmodulin, and 0.5 nM GST- tagged CaMKII5. After shaded incubation of the protein-probe mixture on ice for 30 min, the premix was dispensed in the assay plate including test inhibitors with 4 fold dilution series of eight concentrations. After 1 hr incubation at room temperature, TR-FRET signals were measured in duplicate using an Envision microplate reader (Perkin Elmer, Waltham, MA, USA) . The solution in each well was excited with a laser (λ = 340 nm) reflected by a dichroic mirror (D400/D505 (Perkin Elmer) through an excitation filter (UV (TRF) 340, (Perkin Elmer)), and fluorescence from Tb and BODIPY were detected through two emission filters (CFP 495 (Perkin Elmer) for Tb, Emission 520 (Perkin Elmer) for BODIPY) .

The percentage of inhibition of test compounds was calculated according to equation (1)

Inhibition (%) = 100 ^χ (μ _Η -Τ) / (μ _Η -μι) (1)

Where T is the value of the wells containing test compounds and μΗ and μι are the mean values of the 0% and 100% inhibition control wells, respectively. The values of the 0 and 100% controls were the signals obtained in the absence and presence of 3 μΜ its parent compound, respectively. The half maximal inhibitory concentration (IC50) of test compounds was calculated by fitting the data with the logistic equation using XLfit (IDBS, Guildford, UK) . The IC50 was classified according to the following activity ranks.

A: less than 10 nM

B: 10 nM or more and less than 100 nM

C: 100 nM or more

The results are shown in Table 2.

Test compounds were suspended in 0.5% [w/v]

methylcellulose/water solution and administered (10 or 30 mg/kg) to male CD (SD) IGS rat (6-8 weeks old, n=4) by the p.o. route (5 mL/kg) . At 2-4 hours after the administration, rats were sacrificed and the hearts were harvested. After washing the isolated hearts with ice-cold saline, connective tissues were removed on ice, and the isolated left ventricle were frozen into liquid nitrogen gas and stored at -80°C.

The left ventricle samples were homogenized in RIPA- buffer containing phosphatase inhibitors and protease

inhibitors. Samples were analyzed by Western blotting using anti-P-PLN (Thrl7, Santa Cruz Biotechnology, sc-17024-R) antibody. The band intensities were quantified using an imaging system and were normalized relative to the vehicle- treated group.
