Description

DfflYDROPYRIMIDONE INHIBITORS OF CALCIUM CHANNEL FUNCTION
FIELD OF THE INVENTION The present invention relates to dihydropyrimidone compounds useful as inhibitors of calcium channel function, pharmaceutical compositions comprising said compounds, and methods of treating calcium channel-dependent disorders including hypertension.
BACKGROUND OF THE INVENTION Calcium channels convert electrical signals in the cell membrane into an increase in intracellular calcium, thereby activating many crucial physiological processes, including muscle contraction, hormone secretion, neurotransmission, synaptic plasticity, regulation of enzymatic activites and gene expression. Calcium channels can be classified into a number of types and subtypes, for example L- (or Cayl), P/Q- (or Cav2.1), N- (or Cav2.2), R- (Cav2.3) and T- (or Cav3) types. T-type calcium channels can, for example, be subclassified into αlG (or Cav3.1), αlH (or Cav3.2), and all (or Cav 3.3) T channels. See, e.g., Catterall et al., Annu. Rev. Cell Dev. Biol. 16, 521-55, (2000); and Perez-Reyes et al., Physiol. Rev. 83, 117-161, (2003). Physiologically, calcium channels are distributed widely. For example, T-type channels can be found in neurons, the heart, kidney, smooth muscle, skeletal muscle, sperm, and endocrine tissues (such as adrenal and pituitary glands and the pancreas). Consequently, T-type calcium channels are thought to be involved in autonomic nervous functions, and in regulation of cardiovascular activities such as heart rate, arterial and venous smooth muscle innervation and tone, pulmonary rate, and other critical processes. Due to their role in modulating many physiological processes, abnormal or unwanted calcium channel activity is also associated with many disease states. Agents which antagonize or agonize the activity of calcium channels have been shown to be useful as therapies for treating a wide variety of diseases and disorders. See, e.g., WO 99/23072; EP 0545845; and Kochegarov et al., Expert Qpin. Ther. Patents. 12, 243-287, (2002). L-channel blockers have a well established role in the treatment of diseases such as hypertension and angina (see e.g. Mannhold et al, Drugs of Today. 30, 103- 122, 1994). Compounds that have exclusively or predominantly T-channel blocking activity or that have dual L- and T-channel blocking activities are considered to be useful for the treatment of hypertension, angina, arrhythmia, congestive heart failure, renal disease, epilepsy, neuropathic pain, and other diseases and conditions. See, e.g., Perez-Reyes et al, Physiol. Rev. 83, 117-161 (2003) and WO 03/07953. T-channel blockers are also useful for the treatment of sleep disorders, mood disorders, depression, migrane headache, neuronal excitability disorders, hyperaldosteronemia, preterm labor, urinary incontinence, brain aging, or neurodegenerative related diseases such as Alzheimer's disease. See, e.g., WO 01/02561; WO 00/02455; JP11035483 and Chemin et al, J. Physiol.. 540, 3-14, (2002). Additionally, T-type calcium channels play a role in pancreatic beta-cell insulin secretion. Therefore, T-type blockers may be useful for treatment of hypo- and hyperinsulinemia and the treatment and/or prevention of type 1 and type 2 diabetes as well as microvascular or macrovascular diseases associated with diabetes. See, e.g., Bhattacharjee et al., Endocrinology. 138, 3735-40, (1997) and WO 00/15845. T-type calcium channel blockers may also be useful in the treatment of cancer. See, e.g., WO 00/59882 and WO 01/019845. Drugs such as mibefradil and efonidipine which block both T and L calcium channels have been shown to be useful or potentially useful in a variety of disease states. Such drugs may have therapeutic advantages over calcium channel blockers that predominantly target the L-channel. For example, mibefradil was shown to be useful for the treatment of hypertension and angina and did not show the negative side-effects including inotropy, reflex tachycardia, vasoconstrictive hormone release or peripherial edema, which are often shown by predominantly L-channel blockers. See, e.g., Sandman et al., J. Clin. Basic Cardiol.. 2, 187-201 (1999) and Glasser et al., J. Clin. Pharmacol.. 38, 659-669 (1998). Also, mibefradil has been shown to be potentially cardioprotective (see e.g. Nillame, Cardiovascular Drugs and Therapy. 15, 41-48 (2001) and Ramires, et al., J. Mol. Cell CardioL. 30, 475-483, (1998)) and renal protective (see e.g. Honda, J. et al., Hypertension, 19, 2031-2037 (2001); Baylis et al., Am. J. Kidney Pis.. 38, 1292-1297 (2001); Qiu, et al., J. Hypertension. 1489-1495 (1999); and Karam et al, Hypertension. 34, 673-678, (1999)). Also, unlike most predominant L-channel blockers, mibefradil has been shown to be potentially useful in the treatment of heart failure. See, e.g., Clozel, et al., Proceedings of the
Association of American Physicians. Ill, 429-437 (1999); Mulder, et al., Journal of the American College of Cardiology. 29, 416 (1997); and Meissner, et al, Exp. Biol. Med 227. 336-44, (2002). Mibefradil may also be useful in the treatment of atherosclerosis (see e.g. Mason, et al., Biochemical Pharmacology, 55, 1843-1852, (1998)) and inflammation (see, e.g., Bilici, et al., Pharmacological Research. 527-531 (2001)). Efonidipine, another calcium channel blocker with a combination of T- and L-channel blocking activities, also shows therapeutic advantages over pure L-channel blockers. See, e.g., Harada, et al., Circ. J. 67, 139-145 (2003); Hayashi, et al, Amer. Heart J.. 16, 116-122 (2003); and Tanaka, et al., Cardiovascular Drug Reviews, 20, 81-92 (2002).

The terms "heterocyclic" or "heterocyclo" as used herein by itself or as part of another group refer to optionally substituted, fully saturated or partially unsaturated cyclic groups (for example, 3 to 13 member monocyclic, 7 to 17 member bicyclic, or 10 to 20 member tricyclic ring systems, preferably containing a total of 3 to 10 ring atoms) which have at least one heteroatom in at least one carbon atom-containing ring. Each ring of the heterocyclic group containing a heteroatom may have 1, 2, 3 or 4 heteroatoms selected from nitrogen atoms, oxygen atoms and/or sulfur atoms, where the nitrogen and sulfur heteroatoms may optionally be oxidized and the nitrogen heteroatoms may optionally be quatemized. The heterocyclic group may be attached at any heteroatom or carbon atom of the ring or ring system, where valance allows. The rings of multi-ring heterocycles maybe either fused, bridged and/or joined through one or more spiro unions. Exemplary heterocyclic groups include azetidinyl, pyrrolidinyl, oxetanyl, imidazolinyl , oxazolidinyl, isoxazolinyl, thiazolidinyl, isothiazolidinyl, tetrahydrofuranyl, piperidinyl, piperazinyl, 2-oxopiperazinyl, 2-oxopiperidinyl, 2-oxopyrrolodinyl, 2-oxoazepinyl, azepinyl, 4-piperidonyl, tetrahydropyranyl, morpholinyl, thiamo holinyl, thiamorpholinyl sulfoxide, thiamorpholinyl sulfone, 1,3-dioxolane and tetrahydro-l,l-dioxothienyl,

and the like. The term "ring" encompasses homocyclic (i.e., as used herein, all the ring atoms are carbon) or "heterocyclic" (i.e., as used herein, the ring atoms include carbon and one to four heteroatoms selected from N, O and /or S, also referred to as heterocyclo), where, as used herein, each of which (homocyclic or heterocyclic) may be saturated or partially or completely unsaturated (such as heteroaryl). Throughout the specification, groups and substituents thereof may be chosen to provide stable moieties and compounds. The compounds of formula I form salts which are also within the scope of this invention. Reference to a compound of the formula I herein is understood to include reference to salts thereof, unless otherwise indicated. The term "salt(s)", as employed herein, denotes acidic and/or basic salts formed with inorganic and/or organic acids and bases. In addition, when a compound of formula I contains both a basic moiety and an acidic moiety, zwitterions ("inner salts") may be formed and are included within the term "salt(s)" as used herein. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful, e.g., in isolation or purification steps which may be employed during preparation. Salts of the compounds of the formula I may be formed, for example, by reacting a compound I with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization. The compounds of formula I which contain a basic moiety may form salts with a variety of organic and inorganic acids. Exemplary acid addition salts include acetates (such as those formed with acetic acid or trihaloacetic acid, for example, trifluoroacetic acid), adipates, alginates, ascorbates, aspartates, benzoates, benzenesulfonates, bisulfates, borates, butyrates, citrates, camphorates, camphorsulfonates, cyclopentanepropionates, digluconates, dodecylsulfates, ethanesulfonates, fumarates, glucoheptanoates, glycerophosphates, hemisulfates, heptanoates, hexanoates, hydrochlorides (formed with hydrochloric acid), hydrobromides (formed with hydrogen bromide), hydroiodides, 2-hydroxyethanesulfonates, lactates, maleates (formed with maleic acid), methanesulfonates (formed with methatiesulfonic acid), 2-naphthalenesulfonates, nicotinates, nitrates, oxalates, pectinates, persulfates, 3-phenylpropionates, phosphates, picrates, pivalates, propionates, salicylates, succinates, sulfates (such as those formed with sulfuric acid), sulfonates (such as those mentioned herein), tartrates, thiocyanates, toluenesulfonates such as tosylates, undecanoates, and the like. The compounds of formula I which contain an acidic moiety may form salts with a variety of organic and inorganic bases. Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases (for example, organic amines) such as benzathines, dicyclohexylamines, hydrabamines (formed with N,N-bis(dehydroabietyl)ethylenediamine), N-methyl-D-glucamines, N-methyl-D-glucamides, t-butyl amines, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quatemized with agents such as lower alkyl halides (e.g. methyl, ethyl, propyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, dibutyl, and diamyl sulfates), long chain halides (e.g. decyl, lauryl, myristyl and stearyl chlorides, bromides and iodides), aralkyl halides (e.g. benzyl and phenethyl bromides), and others. Prodrugs and solvates of the compounds of the invention are also contemplated herein. The term "prodrug", as employed herein, denotes a compound which, upon administration to a subject, undergoes chemical conversion by metabolic or chemical processes to yield a compound of the formula I, or a salt and/or solvate thereof. Solvates of the compounds of formula I are preferably hydrates. Any tautomers which may exist are also contemplated herein as part of the present invention. Various forms of prodrugs are well known in the art. For examples of such prodrug derivatives, see: a) Design of Prodrugs. edited by H. Bundgaard, (Elsevier, 1985) and
Methods in Enzymology. Nol.42, p. 309-396, edited by K. Widder, et al. (Acamedic Press, 1985); b) A Textbook of Drug Design and Development, edited by Krosgaard- Larsen and H. Bundgaard, Chapter 5, "Design and Application of Prodrugs," by H. Bundgaard, pp. 113-191 (1991); and c) H. Bundgaard, Advanced Drug Delivery Reviews. 8, 1-38 (1992), each of which is incorporated herein by reference. All stereoisomers of the present compounds, such as those which may exist due to asymmetric carbons on the R substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons, e.g., afropisomers) and diastereomeric forms, are contemplated within the scope of this invention. Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations.
Methods of Preparation The compounds of the present invention may be prepared by methods such as those illustrated in the following Schemes 1 through 6. Solvents, temperatures, pressures, and other reaction conditions may be selected by one of ordinary skill in the art. Starting materials are commercially available or readily prepared by one of ordinary skill in the art. Scheme 1 describes the preparation of the pyrimidine core intermediates. See J. Med. Chem. 33 (5), 1510, (1990). Briefly, an aryl (as depicted in schemes 1-6) or heteroaryl aldehyde 1 is condensed with ketone 2 in the presence of a base such as pyridine to afford a-benzylidine intermediate 3, which is reacted with O- methylisourea or S-methylisothiourea to afford the core structure 4. Scheme 1
Figure imgf000017_0001
In scheme 2, the pyrimidine core intermediate 4 is alkylated in the presence of a base, such as sodium hydide with a side-chain intermediate 5 to provide intermediate 6. L is a leaving group such as bromo, iodo, or tosyl, and P is an amino protecting group such as Boc or Cbz. Acids such as TFA or HCl are employed to remove acid-labile protecting groups P (such as Boc groups) and, at the same time, hydrolyze the metliyoxy or methylthio group to afford intermediate 7. Condensation of the side-chain amine of 7 with an acid chloride in the presence of base such a triethylamine or with an acid in the presence of DCC affords the compound of invention la. When protecting groups, "P", of intermediate 6 are removed under non-acidic conditions the 2-methyoxy or 2-methylthio group may remain intact and require a separate hydrolysis step for its removal. For example, if P is CBZ and X is oxygen, hydrogenolysis removes the CBZ group to afford 8 and the 2-methyoxy group is hydrolyzed in a separate step using, for example, TFA or aqueous HCl to afford 7.

As described in scheme 4, alkylation of core intermediate 4 with protected acid 10 provides intermediate 11, which following deprotection, affording 12, and condensation of the acid group with an amine in the presence of DCC provides compound of the invention If. Scheme 4
Figure imgf000019_0001
12 Scheme 5 describes the treatment of the pyrimidine core intermediate 4 with a compound 13 (having two leaving groups, L and L) in the presence of a base such as sodium hydride thereby providing intermediate 14. The reaction of 14 with a urea in the presence of a base such as sodium hydride provides intermediate 15. Hydrolysis of 15 provides compound of the invention Ig. Alternatively, treatement of core intermediate 4 with a compound 16 having a leaving group and a protected alcohol provides intermediate 17, which upon deprotection provides intermediate 18. Reaction of 18 with an alkane or arene sulfonyl chloride (such as methane sulfonyl chloride or toluene sulfonyl chloride) in the presence of a base such as triethylamine provides intermediate 19 which can be reacted with urea 19 to provide product of the invention Ig.

Finally, as illustrated in Scheme 6, a compound of the invention Ih may contain functionality in the Rl group, such an azide, which can be further modified. For example, reduction of the azide group of Ih with hydrogen in the presence of a palladium catalyist provides product of the invention Ig. Scheme 6

The following assays may be employed in ascertaining the degree of activity of a compound as an antagonists of calcium channels (especially T-type and or L-type calcium channels). Compounds described in the following Examples have demonstrated measurable activity as calcium channel antagonists. Aortic ring protocol: Male Sprague-Dawley rats (250-300 g) were euthanized by CO2 and cervical dislocation. The thoracic aorta was removed and placed in physiological salt solution (PSS) of the following composition, in mM: 118.4 NaCl, 4.7 KCl, 1.2 MgCl2 , 1.2 KH 2PO4 , 1.9 CaCl2, 25.0 NaHCO3 , and 10.1 glucose. The aorta was cleaned of adherent connective tissue and cut into rings approximately 3 mm wide. The endothelium was removed from each ring by placing the ring on a dissecting probe and gently rolling on PSS-moistened filter paper. Each rat aortic ring was mounted for isometric force recording on stainless steel wires in a 10 ml organ chamber between a micrometer for control of tissue length and a GRASS® FT-03 force transducer. Mechanical responses were recorded using a PowerLab® data acquisition system. The organ chambers contained PSS aerated with 95% O2, 5% CO2 to maintain the pH at 7.4. The experiments were performed at 37°C. The tissues were gradually stretched over a 2 hr equilibration period to approximately 2 g preload.
Compounds were tested for the ability to produce relaxation of aortic rings that were contracted with 80 mM KCl.
Patch-clamp electropysiologv: T- and L-type calcium currents were studied using cell lines stably expressing the cloned human T- (alphalH) and L-type calcium ion channel genes. Membrane current recordings were made with Axopatch 200A and 200B integrating patch-clamp amplifiers (Axon Instruments, Foster City, CA) using the whole-cell variant of the patch-clamp technique. The bath solution, which replaced the cell culture media during experiments, for T-type calcium current experiments contained (in mM): 140 NaCl, 5 CaCl2, 4 KCl, 1 MgCl2, 10 Glucose, 10 HEPES (pH 7.35, NaOH). The patch pipette filling solution used T-type calcium current experiments experiments contained (in mM): 130 KCl, 1 CaCl2,l MgCl2, 5 ATP-K2, 10 EGTA, 10 HEPES (pH 7.2, KOH). The bath solution for L-type calcium current experiments contained (in mM): 103 NaCl, 30 BaCl2, 4 CsCl, 1 MgCl2, 10 glucose, 10 HEPES (pH 7.35, NaOH). The pipette solution used in L-type calcium current experiments contained (in mM): 20 CsCl, 20 tetraethylammonium chloride, 82 glutamate, 3 ATP-Mg, 0.5
NaH2PO4, 3 Na2-creatine PO4, 11 EGTA, 10 HEPES (pH 7.25, CsOH). The bath and pipette solutions used in L-type calcium current studies minimized current "rundown" over time. Barium has a greater conductance than calcium through the L-type calcium channel and was used as charge carrier in L-type calcium channel experiments to increase whole-cell current amplitude. No protein was present in bath solutions, so concentrations of test agents represent free or unbound test agent. T-type calcium currents were elicited by repetitive 200ms voltage steps to -30 mV applied from a holding potential of -80 mV. The repetitive voltage steps were continuously applied at a frequency of 0.2 Hz throughout experiments. Effects of compounds were calculated by measuring inliibition of peak current elicited during voltage steps. Peak current was measured from the holding current at -80 mV and used to calculate per cent inhibition. L-type calcium currents were elicited by repetitive 200ms voltage steps to 30 mV applied from a holding potential of -50 mV. The repetitive voltage steps were continuously applied at a frequency of 0.2 Hz throughout experiments. Effects of compounds were calculated by measuring inhibition of peak current recorded at 30 mV. Data were sampled at rates at least two times the low pass filter rate. The flow rate was kept constant throughout the experiments (~ 5 ml/min). All membrane currents were recorded at 25°C.
