Description

WO 2009/079624 PCT/US2008/087397 4-IMIDAZOLIDINONES AS KV1.5 POTASSIUM CHANNEL INHIBITORS FIELD OF THE INVENTION The present invention relates to compounds that are effective as Kv1.5 potassium channel inhibitors. The present invention also relates to compositions comprising 5 certain Kv1.5 potassium channel inhibitors, and to methods for treating cardiac arrhythmia. BACKGROUND OF THE INVENTION Atrial fibrillation (AF) is a frequently encountered cardiac arrhythmia in the clinical setting. It affects nearly 3 million people in the United States and its prevalence 10 increases with the aging of the population. AF is most often treated with class III antiarrhythmic agents, acting at both the atrial and ventricular levels. Commonly used or prescribed antiarrhythmic drugs inhibit various potassium channels, and prolong ventricular repolarization. Prolongation of ventricular repolarization can in turn precipitate the occurrence of life-threatening-ventricular arrhythmias, mainly 15 Torsades de Pointes (TdP). Certain atrial-selective antiarrhythmic agents offer one possibility of increased therapeutic efficacy and safety by minimizing cardiac proarrhythmia inherent in conventional antiarrhythmic therapies. There is an unmetneed to provide certain new compounds that function as effective 20 atrial-selective antiarrhythmic agents and which do not affect ventricular rhythm. In addition, there is an unmet need to provide certain new compounds that function as effective atrial-selective antiarrhythmic agents and that are compatible with other cardiac devices, cardiac protocols, therapies, and medications.

DETAILED DESCRIPTION OF THE INVENTION 5 Kv1.5 potassium channel inhibitors of the present invention are capable of treating and preventing arrhythmia in the atrial portion of the human heart or in the heart of certain animals. It has been discovered that functional Kv1.5 potassium channels are found in human atrial tissue but not in human ventricular myocytes. Without wishing to be limited by theory, it is believed the inhibition of the Kv1.5 voltage-gated 10 Shaker-like potassium (K+) ion channel can ameliorate, abate, or otherwise cause to be controlled, atrial fibrillation and flutter without prolonging ventricular repolarization. DEFINITIONS As used herein, all percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (0C), unless otherwise 15 specified. All documents cited are in relevant part; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention. Throughout the description, where compositions are described as having, including, or comprising specific components, or where processes are described as having, 20 including, or comprising specific process steps, it is contemplated that compositions of the present invention also consist essentially of, or consist of, the recited components, and that the processes of the present teachings also consist essentially of, or consist of, the recited processing steps. In this specification, where an element or component is said to be included in and/or 25 selected from a list of recited elements or components, it should be understood that the element or component can be any one of the recited elements or components -4- WO 2009/079624 PCT/US2008/087397 and can be selected from a group consisting of two or more of the recited elements or components. The use of the singular herein includes the plural (and vice versa) unless specifically stated otherwise. In addition, where the use of the term "about" is before a 5 quantitative value, the present invention also includes the specific quantitative value itself, unless specifically stated otherwise. It should be understood that the order of steps or order for performing certain actions is immaterial so long as the present teachings remain operable. Moreover, two or more steps or actions can be conducted simultaneously. 10 As used herein, unless otherwise noted, "alkyl" whether used alone or as part of a substituent group refers to saturated straight and branched carbon chains having 1 to 20 carbon atoms or any number within this range, for example, 1 to 6 carbon atoms or 1 to 4 carbon atoms.

is, for the purposes of the present invention, considered a heteroaryl group. When a fused ring unit contains heteroatoms in both a saturated and an aryl ring, the aryl ring will predominate and determine the type of category to which the ring is assigned. 15 For example, 1,2,3,4-tetrahydro-[1,8]naphthyridine having the formula: H N N is, for the purposes of the present invention, considered a heteroaryl group. The terms "treat" and "treating," as used herein, refer to partially or completely alleviating, inhibiting, ameliorating and/or relieving a condition from which a patient is 20 suspected to suffer. -9- WO 2009/079624 PCT/US2008/087397 As used herein, "therapeutically effective" refers to a substance or an amount that elicits a desirable biological activity or effect. Except when noted, the terms "subject" or "patient" are used interchangeably and refer to mammals such as human patients and non-human primates, as well as 5 experimental animals such as rabbits, rats, and mice, and other animals. Accordingly, the term "subject" or "patient" as used herein means any mammalian patient or subject to which the compounds of the invention can be administered. In an exemplary embodiment of the present invention, to identify subject patients for treatment according to the methods of the invention, accepted screening methods 10 are employed to determine risk factors associated with a targeted or suspected disease or condition or to determine the status of an existing disease or condition in a subject. These screening methods include, but are not limited to for example, conventional work-ups to determine risk factors that may be associated with the targeted or suspected disease or condition. These and other routine methods allow 15 the clinician to select patients in need of therapy using the methods and compounds of the present invention. The term "substituted" is used throughout the specification. The term "substituted" is defined herein as a moiety, whether acyclic or cyclic, which has one or more (e.g. 1 10) hydrogen atoms replaced by a substituent as defined herein below. Substituents 20 include those that are capable of replacing one or two hydrogen atoms of a single moiety at a time, and also those that can replace two hydrogen atoms on two adjacent carbons to form said substituent. For example, substituents that replace single hydrogen atoms includes, for example, halogen, hydroxyl, and the like. A two hydrogen atom replacement includes carbonyl, oximino, and the like. Substituents 25 that replace two hydrogen atoms from adjacent carbon atoms include, for example, epoxy, and the like. When a moiety is described as "substituted" any number of its hydrogen atoms can be replaced, as described above. For example, difluoromethyl is a substituted C, alkyl; trifluoromethyl is a substituted C, alkyl; 4-hydroxyphenyl is a substituted aryl ring; (N,N-dimethyl-5-amino)octanyl is a substituted C8 alkyl; 3 30 guanidinopropyl is a substituted C3 alkyl; and 2-carboxypyridinyl is a substituted heteroaryl. - 10- WO 2009/079624 PCT/US2008/087397 At various places in the present specification, substituents of compounds are disclosed in groups or in ranges. It is specifically intended that the description include each and every individual subcombination of the members of such groups and ranges.

Next, the material was dissolved in 2 mL of DMF with stirring. This was followed by the addition of cesium carbonate (557 mg, 1.71 mmol). Lastly, iodomethane (0.17 mL, 3.41 mmol) was added to the reaction in one portion via syringe. The reaction 10 vial was then capped and heated in a Biotage Initiator 60 microwave at 150 0C for 5 minutes. The reaction was then cooled to room temperature and de-capped. The reaction mixture was then partitioned between 20 mL of de-ionized water and 20 mL of methylene chloride and separated. The remaining aqueous layer was further extracted with 2 more 20 mL portions of methylene chloride. The combined organic 15 extracts were filtered over anhydrous MgSO 4 and evaporated dryness. The resulting material was purified by flash column chromatography to afford a clear viscous syrup, 256 mg, chemical yield 81.9%.

Kv1.5 is stably over expressed in HEK cells. Microelectrodes are pulled from borosilicate glass (TW150) and heat polished (tip resistance, 1.5 to 3 megaohms). The external solution is standard Tyrodes solution. The internal (microelectrode) solution contained: 110 mM KCI, 5 mM K 2 ATP, 5 mM K 4 BAPTA, 1 -117- WO 2009/079624 PCT/US2008/087397 mM MgCl 2 and 10 mM HEPES, adjusted to pH 7.2 with KOH. Command potentials are applied for 1 second to +60mV from a holding potential of -70 mV using Axon software (pClamp 8.1) and hardware (Axopatch 1D, 200B). Compounds are prepared as 10-20mM DMSO stocks and diluted to appropriate test concentrations. After 5 stable currents are achieved, compounds are perfused onto the cells and the cells are pulsed every 5 seconds until no further changes in current are evident at a given compound concentration. Inhibition is measured at the end of the 1 second pulses and expressed relative to controls. Kv1.5 inhibition is estimated by single point determinations done at 1 IM. 10 Generally following this procedure, results for representative compounds according to the present invention are listed in Table 2 below.
