Description

USE OF ION CHANNEL MODULATORS IN THE PROPHYLAXIS AND TREATMENT OF INFLAMMATORY AND IMMUNOLOGICAL DISEASES

Field of the Invention

The present invention relates to the use of ion channel modulators in the treatment of inflammatory and immunological diseases, and more particularly to the use of heterocyclic compounds which inhibit the interaction between the pore-forming (alpha) subunits of Kv1 voltage-gated potassium channels and accessory (Kvbeta subunit) proteins.

Background to the Invention

Voltage-dependent potassium (Kv) channels conduct potassium ions across cell membranes in response to changes in the membrane voltage and thereby can regulate cellular excitability by modulating (increasing or decreasing) the electrical activity of the cell.

Mammalian homologues (Kv1.1-Kv1.8) of so called Kv1 potassium channel alpha subunits encoded by the Drosophila Shaker gene can form tetrameric protein complexes that span the plasma membrane of cells and allow the passage of K+ ions. These tetrameric protein complexes of KvLx channels constitute the ion channel pore-forming domain.

Functional Kv1 channels consist of a tetramer of transmembrane spanning KvIx channel subunits may be associated with and regulated by accessory (Kvbeta) proteins that are able to modulate the function of ion channel pore- forming domains (for reviews, see: Xu, J. & Li, M., Trends Cardiovasc. Med., 1998, 8, 229-234; Pongs, O., et al., Ann. N.Y. Acad. ScL, 1999, 868, 344- 355).

Functional Kv1 channels can exist as multimeric structures formed by the association of either identical or dissimilar Kv1 ,x and/or Kvbeta proteins. Modulation of functional Kv1 channel complexes by Kvbeta subunits is believed to be Kv subfamily specific (Sewing et al., Neuron 1996, 15, 455- 463).

Kvbeta subunits bind to Kv1.x channel alpha subunits through an interaction domain known as the T1 domain' or 'tetramerisation domain" located on the N-terminus of Kv1.x channel alpha subunits. The T1 domain was originally identified as an amino-terminal fragment of Kv1.x channels that was necessary for alpha subunit assembly (Li et al,, Science, 1992, 257, 1225- 1229; Shen et al., Neuron, 1993, 11 , 67-76). The putative sequence of the interaction site between KvLx alpha subunits with Kvbeta subunits has been determined and a sequence identified within the so-called T1 domain that is necessary for this interaction (Yu et al., Neuron, 1996, 16, 441-453; Sewing et al. Neuron 1996, 15, 455-463). More recently, elucidation of the crystal structure of the interaction between the Kv1.1 T1 domain and the Kvbeta2 subunit, has established the current understanding of sequence of the critical interaction site between Kv1.1 channels and Kvbeta subunits (Gulbis et al., Science, 2000, 289, 123-127).

"KvIx" channels consist of at least 8 members which include one or more of the following mammalian channels: Kv1.1 , Kv1.2, Kv1.3, Kv1.4, Kv1.5, Kv1.6, Kv1.7, Kv1.8 and any mammalian or non-mammalian equivalents or variants (including splice variants) thereof.

"Kvbeta" proteins may include one or more of the following mammalian subunits: Kvbetai .1 , Kvbeta 1.2, Kvbeta1.3, Kvbeta2.1 , Kvbeta2.2, Kvbeta3, Kvbeta3.1 , Kvbeta4 and any mammalian or non-mammalian equivalents or variants (including splice variants) thereof.

At a functional level, interactions between KvIx channels and Kvbeta proteins can confer modulation (increasing or decreasing) of a number of features of functional Kv1 channels including, but not limited to (i) the transport or chaperone of Kv1.x channels to the plasma membrane of a given cell type (e.g Shi et al., Neuron, 1996, 16, 843-852) and/or (ii) gating properties such as channel inactivation (for example see Rettig et al., Nature, 1994,369, 289-294; Heinemann et al., Journal of Physiology, 1996, 493, 625- 633; Bahring et al., Molecular Membrane Biology, 1994, 21 , 19-25).

In addition to modulation of Kv channel "Inactivation", which refers to the closing of the Kv channel by any mechanism such as by N-type inactivation, Kv beta subunits can also exert effects on other gating properties (see HiIIe, B. Ionic Channels of Excitable Membranes, Sunderland, M A, 1992 by mechanisms which may alter the time and voltage dependency of the open (conducting state), closed (non-conducting state) and inactivated states (nonconducting state) of Kv1.x channels.

Furthermore, the interaction between specific Kvbeta subunits and different Kv1.x channel compositions may confer differential modulation to Kv1.x channei currents (Bahring et al., Molecular Membrane Biology, 1994, 21 , 19- 25). This phenomenon may account for the wide diversity of K+ channels. However, exact subunit compositions of native K+ channels and the physiologic role that particular channels play are, in most cases, stil! unclear.

Compounds which inhibit the interaction between Kv1.x channels and Kvbeta proteins and thus preserve or enhance either the conducting state of Kv1.x channels (e.g. though reducing the rate of KvLx channel inactivation) and/ or increase the transport of KvLx channels to the plasma membrane, are defined as "KvLx channel openers" (KvLx channel opening)

Compounds which inhibit the interaction between Kv1.x channels and Kvbeta proteins and thus preserve either the closed state of Kv1.x channels and/or decrease the transport of Kv1.x channels to the plasma membrane, are defined as "KvLx channel inhibitors" (KvLx channel inhibition)

Such KvLx channel openers or KvLx channel inhibitors have potential utility in the treatment, prevention, inhibition, amelioration or alleviation of symptoms of a number of inflammatory and immunological diseases (or a disorder involving immunosuppression) including inflammatory bowel disease, rheumatoid arthritis, graft rejection, asthma, chronic obstructive pulmonary disease, multiple sclerosis cystic fibrosis and atherosclerosis.

Multiple sclerosis (MS) affects around 350,000 persons in the US aione, with an incidence of 30 patients per 100,000. Internationally, >1 million worldwide are affected with MS (MedTRACK Epidemiology Report, 2006). MS presents more often in populations of northern European ancestry and also affect females more than males by a ratio of 1.6-2:1.

MS significantly affects the quality of life for most patients over many years, with disease lasting, on average, 30 years. MS is unpredictable and symptoms can range from mild to severe, brief to persistent and include: fatigue, visual problems, difficulty walking, numbness or tingling in the hands and feet, dizziness, pain, loss of muscle strength and movement, stiffness and spasms, anxiety, cognitive disorders, speech problems and incontinence.

MS can manifest as one of four clinical courses of the disease, which range in severity between mild to severe. These are characterised as:

(i) 'Relapsing-Remitting' - the most common form of MS at the time of initial diagnosis, affecting 85% of suffers,

(ii) 'Primary-Progressive' - a relatively rare form affecting 10% of suffers,

(Ni) 'Secondary-Progressive' - 50% of people with relapsing-remitting MS develop this form of the disease within 10 years of their initial diagnosis, before treatment. Long-term data are not yet available to demonstrate if secondary progression is significantly delayed by treatment.

(iv) 'Progressive-Relapsing': a relatively rare form affecting 5% of suffers.

MS is a progressive degenerative disease of the CNS that is characterised by the destruction and subsequent loss of the myelin sheath around nerves, leaving scar tissue called sclerosis. These damaged areas are also known as plaques or lesions. When myelin or the nerve fibre is destroyed or damaged, the ability of the nerves to conduct electrical impulses is disrupted, causing debilitating symptoms that vary depending on the site of the sclerosis within the CNS. Although the precise cause of MS is not yet fully understood the presence of immune infiltrates in the CNS white matter of MS patients suggests that myelin damage is immune mediated (see Beeton, C. and Chandy, K. G. (2005), Neuroscientist, 11 , 550-62). An autoimmune aetiology for MS is supported by the induction of experimental autoimmune encephalomyelitis (EAE) which resembles MS in rodent models following immunisation with myelin derived antigens.

K⁺-channels and T-cells

In MS, myelin-reactive T-cells (thymus cells or lymphocytes) exhibit a memory phenotype [Allegretta, M. et a/ (1990), Science, 247,718-721 ; Lovett-Racke, A.E. et a/ (1998), J. CHn. Invest. 101 ,725-730; Scholz, C. e^ a/ (1998), J. Immunol. 160,1532-1538; Markovic-Plese, S. et al (2001), J. CHn. Invest. 108,1185-1194] and are believed to contribute to the inflammatory attack on the CNS due to their ability to induce experimental autoimmune encephalomyelitis (EAE) in animals models of MS [Holoshitz, J. et al (1984), Eur. J. Immunol. 14,729-734]. Therapeutic strategies designed to specifically suppress the function of chronically activated memory T-cells (effector memory) without impairing the function of naϊve T-cells may therefore afford significant advantage in the treatment of MS.

The existence of a novel K⁺ channel pattern in chronically activated encephalitogenic myelin-reactive human memory T-cells has recently been reported [Wuiff, H. et al (2003), J Clin Invest 111 , 1703-13]. These cells specifically up-regulated Kv1.3 channels 48hrs after activation with the myelin antigen, Myelin Basic Protein (MBP), with no change in the surface expression of other ion channel targets such as IKCaL Furthermore, this phenotype was not reflected in T-cells from MS patients, activated with the control antigens: glutamate acid decarboxylase 65 (GAD65), insulin-peptide or ovalbumin-specific and mitogen-activated T-cells from MS patients, or in myelin antigen activated T-cells from healthy controls (Wulff et al., 2003).

In vitro characterization of CD4⁺ T-cells has revealed the existence of functional Kv1.3 channels, the surface density of which increases with cell proliferation. During myelin basic protein (MBP) induced T-ceil proliferation there is an influx of calcium ions through calcium release-activated calcium channels which is counterbalanced by potassium efflux. Thus, block of Kv1.3 channels inhibits cell proliferation in MBP - specific T-cells, where an external stimulus is required for proliferation, but does not affect cell proliferation of transformed cells such as Jurkat JH6.2.

In human T-cells, the voltage-gated potassium channel, Kv1.3, exists as tetramers of four identical subunits and contributes to controlling the resting membrane potential [Cahalan, M. D. and Chandy, K. G. (1997), Curr Opin Biotechnol. 8, 749-56; Leonard, R.J. et a/ (1992), Proc. Natl. Acad. Sci. USA. 89, 10094-10098]. Kv1.3 is a primary regulator of Ca²⁺ signalling in T-cells. Optimal T-ce!l activation requires Ca entry from the external milieu through Ca²⁺-release-activated channels. Ca²⁺ influx depolarizes the membrane and dissipates the electrochemical gradient required for further Ca²⁺-entry. Kv1.3 channels, in addition to IKCa channels, provide the cation efflux, necessary for sustained Ca²⁺-entry which is required for mitogen-stimulated cytokine production and proliferation of T-cells.

Kv1.3 channels exist as protein complexes forming functional channels. Components of such protein complexes including Kvβ2 accessory proteins, are able to modulate channel functions such as cell surface expression or kinetics (c.f Kvβi) [Lazaroff, M.A. et a/ (2002), J. Physiol. 541 , 673-83; Shi, G ef a/ (1996), Neuron 16, 843-852; Nagaya, N., and Papazian, D. M. (1997), J. Biol. Chem. 272, 3022-3027]. Kvβ2 accessory proteins which are cytosolic accessory proteins have been shown to be the predominant Kvβ subunit expressed in mouse T-celis (Autieri, M. V. et al (1997), J. Neuroimmunol. 77, 8-16) and Kvβ2 was significantly increased at both the mRNA transcript level and protein level following mitogen stimulation (McCormack, T. et a/ (1999), J Biol. Chem. 274, 20123-20126). Kvβ2 accessory proteins bind to the intracellular N-terminus of Kv channels such as Kv1.3 at a site known as the T1 domain (Sewing, S. et at (1996), Neuron 16, 455-63). These Kvβ2 accessory proteins form a 4-fold symmetric structure to complement the tetrameric nature of the Kv1.3 channel counterpart. The recent, elucidation of the crystal structure of the interaction between the Kv1.x channel T1 domains and the Kvβ2 subunit, has defined the sequence and nature of this interaction site (Gulbis, J. M. et al (2000), Science. 289,123-7; Long, S.B. et al (2005), Science. 309, 897-903). Furthermore, each Kvβ2 subunit is an oxidoreductase enzyme with structural homology to 3α-hydroxysteroid dihydrodiol dehydrogenase (3α-HSD) that has been shown to possess a binding site for a nicotinamide co-factor. Indeed NADP+ was found to be bound within a deep cleft within the crystal structure of Kvbeta2 and was shown to interact with Kvβ2 through an array of intramolecular hydrogen bonding and van der Waals interactions (Gulbis, J. M. et ai (1999), Cell. 97, 943-52).

Given the pivotal role of Kvβ2 subunits in the function of Kv1.3 channels in T- cells, inhibition of the interaction between Kv1.3 channels and Kvβ2 accessory proteins is anticipated to lead to selective inhibition of in Kv1.3 channel activity following mitogen stimulation.

Inhibition of Kv1.3 channels induces membrane depolarisation of T-ce!is. In turn this leads to an attenuation of the rise in intracellular Ca²⁺ concentration that occurs upon cell stimulation, which is required for T-cell proliferation (Lin, CS. et al. (1993), J. Exp. Med. 177, 637-645). Peptidyl blockers, specific for Kv1.3 channels, such as margatoxin (Koo er a/., 1997, J., Immunol. 158, 5120-8) and charybdotoxin (Price et al., 1989, Proc. Natl. Acad. Sci. USA. 86, 10171-10175), have been demonstrated to inhibit T-cell proliferation in in vitro protocols. Furthermore, the Kv1.3 inhibitor margatoxin (Koo et al., 1997) has been shown to display immunosuppressant activity in vivo as margatoxin attenuates the Delayed-Type Hypersensitivity (DTH) response in the miniswine (Koo et al., 1997). Significantly, selective blockade of T-cell Kv1.3 channels, using ShK (a 35 amino acid peptide from the sea anemone Stichodactyla helianthus) has also been shown to ameliorate the model MS disease (EAE) in Lewis rats, providing additional support for the role for Kv1.3 channels as a key target in the search for novel therapeutics for the treatment of MS.

Attempts have also been made to identify non-peptide-based inhibitors of Kv1.3 channels. In this regard, the complex natural product correolide, a nortriterpene, has been shown to inhibit Kv1 ,3 channels by binding to an intracellular site and preferentially blocks open or inactivated channel states of the channel. In in vitro immunological assays with human T-cells, correolide attenuates the Ca²⁺-dependent pathway of IL-2 production and suppresses, in a reversible manner, T-cell proliferation. Two analogues of correolide with appropriate pharmacokinetic properties suppress the deiayed-type hypersensitivity response to tuberculin in vivo in the mini-swine, further indicating that targeting Kv1.3 channels represents a novel approach to immunosuppressant therapy (Koo et al., 1999). As summarised by Schmalhofer et al. [(2002), Biochemistry. 41 , 7781-94] correolide and its analogues also appear to inhibit Kv1.1 channels present in some peripheral nerve terminals, thereby causing acetylcholine release, which may explain some of the limited toxicity observed in vivo with these compounds. In addition a number of other small molecule inhibitors of Kv1.3 have been described such as UK-78282 (Hanson et al., 1999, Br. J. Pharmacol, 126, 1707-1716), WIN 17317-3 [(Nguyen et al., 1996, MoI. Pharmacol. 50, 1672- 1679; Hill et al., 1995, MoI. Pharmacol. 48, 98-104)] and verapamil [(Chandy βt al., 1984, Exp Med. 160, 369-85; Rauer & Grissmer, 1996, MoI. Pharmacol. 50, 1625-1634)]. Neither WIN 17317-3 nor verapamil appear to be viable drug development candidates as they block, with high affinity, voltage-gated sodium and calcium channels, respectively.

More recently further studies have attempted to find more potent small molecule inhibitors of Kv1.3 channels. These include Psora-4, the C18 analogue of correolide, and trans 4-pheny!-4-(3-(2-methoxyphenyl)-3-oxo-2- azaprop-1-yl)cyclohexanone, but none are specific for Kv1.3 and also inhibit other Kv channels such as the cardiac Kv1.5 channel [(Schmitz et al., 2005, MoI Pharmacol. 68, 1254-70; Beeton & Chandy 2005, Neuroscientist 11 , 550- 62)]. Most recently PAP-1 , a 5-methoxy-psoralen analogue has been shown to inhibit to Kv1.3 channels with a 23-fold selectivity over cardiac Kv1.5 channels (Schmitz et al., 2005).

While Kv1.3 channels appear to represent a good therapeutic approach to modulate the pathologic immune responses mediated by effector memory T- cells, Kv1.3 are also expressed on other tissues such as the CNS, kidney, liver skeletal muscle, platelets, macrophages, testis and osteoclasts raising the possibility that Kv1.3 blockers could have adverse effects. However, in a 28-day toxicity study performed in rats, the Kv1.3 inhibitor PAP-1 administered by gavage, failed to induce any histopathologicai changes in any tissues examined including those that are reported to express Kv1.3 channels (Beeton et al., 2006, Proc. Natl. Acad. ScL USAΛ0Z, 17414-9). The relative safety of compounds that target Kv1.3 channels may also be in part due to the differential nature of the Kv1.3 channel targets between T-celis and other tissues such as the CNS, such that compounds may be optimised to display a differential affinity for the Kv1.3 homotetrameric protein complexes present in T-cells versus the heterotetrameric Kv1.3 channel protein complexes present in the CNS.

On the basis of the detail provided above, selective Kv1.3-based therapies that suppress the activation of effector memory T-cells without significant impairment of the proliferation of naϊve and central memory T-cells have potential utility as therapeutics for the management of MS and other T-cell mediated disorders that have also been reported to exhibit a memory phenotype such as type-1 diabetes, rheumatoid arthritis, psoriasis, Hashimoto's disease and Crohn's Disease.

Thus, it would be desirable to identify KvLx channel openers and KvLx channel inhibitors for the prophylaxis or treatment of inflammatory and immunological diseases. Using assays based on the interaction between KvLx channel T1 domains and Kvbeta subunits immobiiised through an affinity tag, we have discovered a new family of heterocyclic compounds which inhibit the interaction between Kvϊx channels and Kvbeta proteins for said use.
