Abstract
Description
Technical Field
[0001] This invention relates to pyridone compounds, their use in inhibiting GIRK1 / 4 channels, and methods of using them to treat diseases or disorders. Prior Technology
[0002] A normal cardiac cycle begins in the sinoatrial node, which generates an excitatory electrical stimulus. This stimulus propagates in an orderly fashion throughout the atrial and ventricular myocardium to induce contraction (systole). At the cellular level, the excitatory electrical impulse triggers the cardiac action potential. The cardiac action potential is characterized by an initial rapid membrane depolarization, followed by a plateau phase, and then repolarization to return to the resting membrane potential. The cardiac action potential controls signal propagation throughout the heart. For example, the rate of initial cellular depolarization determines the speed at which the excitatory stimulus propagates. The duration of the repolarization phase determines the action potential duration (APD) and refractory period, or the time during which cardiomyocytes are unable to respond to another electrical stimulus.
[0003] Abnormalities in cardiac action potentials are associated with arrhythmias. For example, excessive reduction in action potential duration and associated effective refractory period can provide a basis for so-called reentrant tachyarrhythmia. In this condition, cardiac impulses do not propagate normally but instead feed back to themselves via excitable tissue to form a reentrant circuit (Waldo et al., Lancet 341, 1189-1193). Existing class III antiarrhythmic drugs are thought to work by prolonging the effective refractory period (APD) and associated effective refractory period (ERP), thereby minimizing the risk of re-excitation and subsequent formation of fibrillary reentrant circuits (Singh et al., British Journal of Pharmacology 39, 675-687).
[0004] Certain class III antiarrhythmic drugs (such as sotalol) are used to treat atrial fibrillation (AF). AF is the most common form of persistent arrhythmia in humans and is characterized by fibrillating contractions that affect atrial function. AF is associated with adverse cardiovascular events. In particular, the presence of AF is an independent risk factor for thromboembolic stroke, heart failure, and all-cause mortality (Estes et al., (2008). Journal of the American College of Cardiology 51, 865-884)(Fang et al., 2008. Journal of the American College of Cardiology 51, 810-815). AF can also reduce the quality of life for some patients by inducing palpitations and reducing exercise tolerance (Thrall et al., 2006. The American journal of medicine 119, 448.e441-419). The goal of antiarrhythmic therapy for AF is to avoid these adverse effects and outcomes.
[0005] A drawback of existing Class III antiarrhythmic drugs is that they prolong the effective refractory period of both the atria and ventricles. Excessive prolongation of ventricular tissue can prolong the QTc interval and may lead to arrhythmias. Some drugs with this mechanism of action (e.g., dofetilide) are known to induce potentially life-threatening ventricular arrhythmias, such as torsades de pointes (Redfern et al., 2003. Cardiovascular Research 58, 32-45). Therefore, there is a need for novel antiarrhythmic therapies for arrhythmia that selectively target atrial tissue rather than ventricular tissue.
[0006] The configuration and duration of cardiac action potentials are controlled at the cellular level through the action of multiple different transmembrane ion channels. For example, the initial depolarization phase is mediated by sodium influx via cardiac-specific Nav1.5 channels. Potassium channels are responsible for the later stages of repolarization and thus contribute to regulating the total duration of the action potential. In fact, class III antiarrhythmic drugs targeting potassium channels (e.g., dofetilide) prolong both the duration of the action potential and the effective refractory period. Several different types of transmembrane potassium channels exist (Schmitt et al., 2014. Physiological reviews 94, 609-653; Tamargo et al., 2004. Cardiovascular research 62, 9-33), including: • Voltage-gated channels (Kv1-9) • Calcium-activated channels (KCa1-2) • Dual-channel design (e.g., TASK) • Inward rectifier channels (Kir1-6)
[0007] While most cardiac potassium channels contribute to the repolarization of both atrial and ventricular tissues in humans, Kv1.5 and GIRK1 / 4 (i.e., G protein-regulated inward rectifier potassium channels 1 / 4) are thought to be present only in the atria (Gaborit et al., 2007. The Journal of Physiology 582, 675-693). This atrial-specific pattern of expression makes these particularly attractive targets for novel antiarrhythmic therapies for AF, as they do not have the adverse ventricular effects of existing class III drugs such as dofetilide.
[0008] Mammalians exhibit four distinct GIRK channels (GIRK 1, 2, 3, and 4; encoded by KCNJ3, KCNJ6, KCNJ9, and KCNJ5, respectively). These transmembrane proteins arrange themselves into tetramers (homoterams or heterotetramers) to form functional potassium channels (Krapivinsky et al., 1995. Nature 374, 135-141). These channels are ligand-gated (i.e., regulated by the binding of ligands to Gi protein-coupled receptors present in the same cell membrane). For example, the GIRK1 / 4 channel is a heterotetramer (two subunits of GIRK1 and GIRK4), strongly expressed in the sinoatrial and atrioventricular nodes, as well as in the atrial myocardium (Wickman et al., 1999. Annals of the New York Academy of Sciences 868, 386-398). One function of this channel is to regulate the autonomic regulation of heart rate. Acetylcholine released upon parasympathetic stimulation of the cardiac vagal efferent neurons binds to Gi-coupled M2 muscarinic receptors in the heart. This releases the Gβγ subunit, which in turn opens GIRK1 / 4 channels to allow potassium outflow from cardiomyocytes, thereby promoting membrane repolarization. In the spontaneously depolarizing pacemaker cells of the sinoatrial node, the intensity of this repolarization determines the time interval between depolarizations, thus determining the heart rate. Because the current mediated by GIRK1 / 4 channels is regulated by acetylcholine, it is called IKAch (Wickman et al., 1999).
[0009] Several pieces of evidence point to the GIRK1 / 4 lineage as a desired antiarrhythmic target for arrhythmias. In animals, vagal stimulation promotes the release of acetylcholine from the vagus nerve and an increase in IKAch. This, in turn, shortens the duration of atrial (but not ventricular) action potentials and the effective refractory period, and can induce arrhythmias via reentry mechanisms (Hashimoto et al., 2006. Pharmacological research: the official journal of the Italian Pharmacological Society] 54, 136-141). IKAch lineage dysregulation has been shown in atrial tissue of individuals with persistent arrhythmias and in animals subjected to rapid atrial pacing (an accepted model for promoting electrical remodeling and arrhythmia susceptibility). Specifically, even in the absence of acetylcholine, the pathway tends to be open (Cha et al., 2006. Circulation 113, 1730-1737; Voigt et al., 2014. Advances in pharmacology (San Diego, CA) 70, 393-409). In these studies, short atrial APD / ERP ratios were observed in both patients and animals.
[0010] Therefore, the development of GIRK1 / 4 blockers will be beneficial for the treatment of a range of heart-related diseases. For these reasons, small molecule inhibitors of GIRK1 / 4 remain needed. Summary of the Invention

[0050] Any formulas given herein are also intended to represent the unlabeled form of the compound as well as the isotopically labeled form. Isotopically labeled compounds have the structures represented by the formulas given herein, except that one or more atoms are replaced by atoms having a selected atomic mass or mass number. Isotopes that may be incorporated into the compounds of this invention include, for example, isotopes of hydrogen.
[0051] Furthermore, the incorporation of certain isotopes, particularly deuterium (i.e., 2H or D), can provide certain therapeutic advantages due to increased metabolic stability, such as increased in vivo half-life, reduced dose requirements, therapeutic index, or improved tolerability. It should be understood that deuterium in this context is considered a substituent in the compounds of this invention. The concentration of deuterium can be defined by an isotope enrichment factor. As used herein, the term "isotope enrichment factor" refers to the ratio between the isotope abundance and the native abundance of the specified isotope. If the substituent in the compound of the present invention indicates deuterium, then such a compound has an isotopic enrichment factor for each specified deuterium atom of at least 3500 (52.5% deuterium doping on each specified deuterium atom), at least 4000 (60% deuterium doping), at least 4500 (67.5% deuterium doping), at least 5000 (75% deuterium doping), at least 5500 (82.5% deuterium doping), at least 6000 (90% deuterium doping), at least 6333.3 (95% deuterium doping), at least 6466.7 (97% deuterium doping), at least 6600 (99% deuterium doping), or at least 6633.3 (99.5% deuterium doping). It should be understood that the term "isotopic enrichment factor" can be applied to any isotope in the same manner as described for deuterium.
[0052] Other examples of isotopes that can be incorporated into the compounds of this invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, and chlorine, such as 3H, 11C, 13C, 14C, 15N, 18F, 31P, 32P, 35S, 36Cl, 123I, 124I, and 125I, respectively. Therefore, it should be understood that this invention includes compounds incorporated with one or more of the aforementioned isotopes (including, for example, radioactive isotopes such as 3H and 14C), or compounds containing non-radioactive isotopes such as 2H and 13C. Such isotopically labeled compounds can be used for metabolic studies (with 14C), reaction kinetic studies (e.g., with 2H or 3H), detection or imaging techniques including drug or substrate tissue distribution determination (e.g., positron emission tomography (PET) or single-photon emission computed tomography (SPECT)), or for use in the radiotherapy of patients. In particular, 18F or labeled compounds may be especially desirable for PET or SPECT studies. Isotopically labeled compounds of the present invention can generally be prepared by conventional techniques known to those skilled in the art or by methods similar to those described in the appended examples and general synthetic schemes, using appropriate isotopically labeled reagents instead of previously used unlabeled reagents.
[0053] Any asymmetric atom (e.g., carbon, etc.) in one or more compounds of the present invention may be present in a racemic or mirror-isomer enriched form (e.g., (R)-, (S)-, or (R,S)- configuration). In some embodiments, each asymmetric atom has at least 50% mirror-isomer excess, at least 60% mirror-isomer excess, at least 70% mirror-isomer excess, at least 80% mirror-isomer excess, at least 90% mirror-isomer excess, at least 95% mirror-isomer excess, or at least 99% mirror-isomer excess in the (R)- or (S)- configuration. If possible, substitutions on atoms having unsaturated double bonds may be present in cis-(Z)- or trans-(E)- form.
[0054] Therefore, as used herein, the compounds of the present invention may be in the form of one of the following: stereoisomers, rotational isomers, tautomers, tautomers or mixtures thereof, for example, as substantially pure geometric (cis or trans) stereoisomers, non-mirror image isomers, optical isomers (enantiomers), racemates or mixtures thereof.
[0055] Based on the physicochemical differences of the components, such as by chromatography and / or fractional crystallization, any resulting mixture of stereoisomers can be separated into pure or substantially pure geometric or optical isomers, non-mirror isomers, and racemates.
[0056] Any racemic derivative of the compounds or intermediates of the present invention can be resolved into optically active enantiomers by known methods, for example, by separating their non-mirror image isomer salts obtained with optically active acids or bases, releasing optically active acidic or basic compounds. In particular, the basic moiety can therefore be used to resolve the compounds of the present invention into their optically active enantiomers, for example, by fractional crystallization with salts formed from optically active acids such as tartaric acid, dibenzoyltartaric acid, diacetylated tartaric acid, di-O,O'-p-toluenetartaric acid, mandelic acid, malic acid, or camphor-10-sulfonic acid.

[0128] Aldosterone synthase inhibitors or pharmaceutically acceptable salts thereof should be understood as active ingredients with properties that inhibit aldosterone production. Aldosterone synthase (CYP11B2) is a mitochondrial cytochrome P450 enzyme that catalyzes the final step in aldosterone production in the adrenal cortex: the conversion of 11-deoxycorticosterone to aldosterone. Inhibition of aldosterone production with so-called aldosterone synthase inhibitors is known to be a successful variant for treating hypokalemia, hypertension, congestive heart failure, atrial fibrillation, or renal failure. Such aldosterone synthase inhibitory activity can be readily determined by those skilled in the art using standard assays (e.g., US 2007 / 0049616).
[0129] Aldosterone synthase inhibitors include steroidal and nonsteroidal aldosterone synthase inhibitors, with the latter being the best.
[0130] The class of aldosterone synthase inhibitors includes compounds with different structural features. For example, reference may be made to compounds selected from the group consisting of: nonsteroidal aromatase inhibitors anastrozole, fazodazole (including its (+)-mirror isomers), and steroidal aromatase inhibitor isomestan, or, in each applicable case, its pharmaceutically acceptable salts.
[0131] The best nonsteroidal aldosterone synthase inhibitor is the (+)-mirror isomer of fazolidinium hydrochloride.

Protecting groups are manipulated according to standard methods of organic synthesis (TW Greene and PGM Wuts, "Protective Groups in Organic Synthesis", 3rd ed., Wiley, NY 1999). These groups are removed at a convenient stage of compound synthesis using methods readily apparent to those skilled in the art. The selection of procedures, reaction conditions, and their sequence of execution should be consistent with the preparation of compounds having formula (I).

Therefore, the present invention includes two possible stereoisomers (unless otherwise indicated in the synthesis) and includes not only racemic compounds but also individual mirror-image and / or non-mirror-image isomers. When a compound is required as a single mirror-image or non-mirror-image isomer, it can be obtained by stereo-oriented synthesis or by resolving the final product or any convenient intermediate. The resolving of the final product, intermediate, or starting material can be influenced by any suitable method known in the art. See, for example, "Stereochemistry of Organic Compounds" by E.L. Eliel, S.H. Wilen, and L.N. Mander (Wiley-Interscience, 1994).

The crystalline forms were characterized using the analytical methods shown in Table 2 below, including X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), ultra-high performance liquid chromatography (UPLC), and NMR.
[0232] XRPD spectra for each crystal form are shown in the figures. A list of characteristic XRPD peaks is provided in the table below and described in the figures. Peaks listed here are given in degrees 2θ (±0.1 degrees). As those skilled in the art will understand, the relative intensities of the individual peaks in the table below may vary due to many factors, such as the orientation effect of the crystals in the X-ray beam or the purity or crystallinity of the analyzed material. Peak positions may also shift with variations in sample height, but the peak positions will remain substantially as defined in the given table. Those skilled in the art will also understand that measurements using different wavelengths will result in different shifts according to the Bragg equation nλ = 2d sin θ. However, such alternative XRPD patterns generated by using alternative wavelengths represent the same material.

Blood was also collected after PO administration at 0.25, 0.5, 1, 2, 4, 7, and 24 hours post-administration.
[0448] It is important to record the exact time of drug administration and sampling. Time points may be changed as needed and for appropriate reasons. The rats were euthanized by CO2 after the last sampling time.
[0449] Blood samples should be immediately placed on ice, frozen to -20°C or lower, and stored until analysis. Test tubes should be stored in plastic bags / shelves pre-labeled with the compound name, sample number, study number, route of administration, time, and date.
[0450] [Bioanalysis]
[0451] Bioanalysis of the formulation
[0452] Aliquots of each dosing formulation were taken, appropriately diluted, and the drug concentration was analyzed. The observed concentrations were scaled using a dilution factor to determine the final concentration.
[0453] Bioanalysis of blood samples
[0454] The concentrations of compounds in whole blood were determined using liquid chromatography-mass spectrometry (LC-MS / MS). 20 μL of each blood sample was precipitated with 100 μL of acetonitrile containing a universal internal standard (cabamapin / telmisartan / verapamil; c = 50 ng / mL). The sample was thoroughly vortexed and then centrifuged (5 min, 4°C). The supernatant (80 μL) was transferred to a clean 96-well plate and mixed with 80 μL of water.
[0455] Samples are injected (1 to 20 μL) onto a suitable analytical column using various isocratic methods and flow rates. The mobile phase typically consists of 0.1% formic acid in water (solvent A) and 0.1% formic acid in acetonitrile (solvent B), and other modifiers may be added if necessary. The compound and internal standard elute at different retention times. The HPLC system is connected to a mass spectrometer. MS / MS analysis is performed using electrospray ionization (ESI), typically in positive ionization mode. Multiple reaction monitoring (MRM) is used to monitor the compound and internal standard.
[0456] The standard curve used for sample quantification spans several log units. The lower limit of quantification (LLOQ) in blood is determined and used as a cutoff value for analytical sensitivity. Known amounts of the compound are incorporated into blood to create quality control samples with six known concentrations exhibiting a unimodal peak. The accuracy of in vivo blood concentration determination is considered acceptable when the intra-assay accuracy of the quality control samples is within 70% to 130% of the expected concentration. Subsequently, pharmacokinetic parameters are calculated using non-compartmental regression analysis with an internal fitting program based on time-concentration data.
[0457] [Pharmacokinetic Analysis]
[0458] Based on time-concentration data, pharmacokinetic parameters were calculated using an internal fitting program via non-compartmental regression analysis. AUC (nM*h) The AUC ultimately refers to the area under the concentration-time curve from t = 0 to the final t. This data is calculated using the linear trapezoidal rule, the log-linear trapezoidal rule (when the decay between time points is exponential), or a combination of both from t = 0 to the final T. Therefore, the choice of method depends on the judgment of the PK analyst (e.g., MAP PTM). CL (mL / min / kg) The clearance rate CL is calculated as dose after IV administration / AUCinf. F(%) The optimal exovascular availability F is calculated as the dose-normalized ratio of extravascular AUCinf to intravenous AUCinf. For example, for orally administered substances: F = [AUCinfPO / PO dose] / [IV AUCinfIV / IV dose] x 100% For crossover design studies, F is calculated for each animal. For studies with continuous sampling but no crossover design, the mean intravenous AUCinf was used to calculate the bioavailability per animal administered via extravascular route. If AUCinf is unavailable (because λz is undefined or because AUC is extrapolated infinitely beyond 25% of AUCinf), then AUC is used to replace AUCinf in the final calculation.
