Description

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 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 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 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 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

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 Shaker-like potassium (K') ion channel can ameliorate, abate, or otherwise cause to be controlled, atrial fibrillation and flutter without prolonging ventricular repolarization.

Step 1: Preparation of tent-butyl 1-(4-methoxyphenethylamino)-2-methyl-1-oxopropan-2-ylcarbamate: The starting BOC-Aib-OH (5.0 g, 24.6 mmol) was dissolved in methylene chloride (200 mL) in a single-neck 500mL flask equipped with a stir bar under an inert N2 atmosphere. Next, 1-(3-dimethylaminopropyl)-ethylcarbodiimide hydrochloride (6.13 g, 32.0 mmol), followed by 1-hydroxybenzotriazole (4.32 g, 32.0 mmol) were added to the mixture and dissolved.
4-methylmorpholine (8.11, 73.8 mmol) was then added to the reaction in one portion via syringe. Lastly, 4-methoxyphenethylamine (3.61 mL, 24.6 mmol) was added to the reaction in one portion also via syringe. The reaction was then vigorously stirred at room temperature for 18 hours then extracted twice with saturated aqueous NaHCO3 (2 x 250 mL) and d.i. H2O (250 mL). The remaining organic layer was then filtered over anhydrous MgS04, and evaporated to dryness on a rotovap.

Next, trifluoroacetic acid (10.9 mL, 141 mmol) was added to the reaction in one portion via syringe increasing the concentration to 25% by volume in acid. The reaction was then vigorously stirred at room temperature for 3 hours. After transferring the mixture to a 500 mL Erlenmeyer flask, the reaction was slowly diluted with saturated aqueous NaHCO3 (100 mL) and d.i. H2O (25 mL). The biphasic mixture was then basified to a constant pH of 9 via the addition of solid KOH. The mixture was separated and the remaining aqueous phase was further extracted with methylene chloride (2 x 100 mL). The combined organic extracts were filtered over anhydrous MgSO4, and evaporated to dryness on a roto-evaporator to give a viscous yellow syrup (3.06 g, chemical yield 92%). 1H-NMR (300 MHz, CDC13) b 7.65 (bs, 1H), 7.09 (d, 2H, J = 8.8 Hz), 6.81 (d, 2H, J = 8.8 Hz), 3.76 (s, 3H), 3.41 (dd, 2H, J =

Step 3: Preparation of 3-(4-methoxyphenethyl)-2-(4-tent-butylphenyl)-5,5-dimethylimidazolidin-4-one: The N-(4-methoxyphenethyl)-2-amino-2-methylpropanamide (1 g, 4.23 mmol) was dissolved in methanol (25 mL) in single-neck 100 mL flask equipped with a stir bar under an inert N2 atmosphere. Next, K2CO3 (644 mg, 4.66 mmol) was added to the reaction in one portion. Lastly, 4-t-butyl benzaldehyde (0.78 mL, 4.66 mmol) was added to the reaction in one portion via syringe. The reaction was then vigorously stirred at room temperature for hours. The reaction was evaporated to dryness on a roto-evaporator. The resulting residue was re-dissolved in methylene chloride (100 mL) and extracted with saturated aqueous NaHCO3 (3 x 100 mL). The remaining organic layer was filtered over anhydrous MgSO4 and evaporated a second time to dryness. Subsequent flash column chromatography using a hexane, HOAc gradient system affords a white solid (935 mg, chemical yield 58%). 1H-NMR (300 MHz, CDC13) b 7.43 (d, 2H, J =

Kv1.5 currents are recorded by the whole cell mode of patch clamp electrophysiology. 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 K2ATP, 5 mM K4BAPTA, 1 mM MgCl2 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 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 M.

Generally following this procedure, results for representative compounds according to the present invention are listed in Table 2 below.
