5-[(1 S)-1 -(4-BROMOPHENOXY)ETHYL]-2H-TETRAZOLE DERIVATIVES AND RELATED COMPOUNDS AS CLC-1 ION CHANNEL INHIBITORS FOR TREATING NEUROMUSCULAR DISORDERS

Technical field

The present disclosure relates to compounds and their use in treating, ameliorating and/or preventing neuromuscular disorders, including the reversal of drug-induced 5 neuromuscular blockade. The compounds as defined herein preferably inhibit the CIC- 1 ion channel. The disclosure further relates to methods of treating, preventing and/or ameliorating neuromuscular disorders, by administering said composition to a person in need thereof.

Background

0 Walking, breathing, and eye movement are examples of essential everyday

physiological activities that are powered by the contractile activity of skeletal muscle. Skeletal muscles are inherently in a resting state and contractile activity occurs

exclusively in response to commands from the central nervous system (CNS). Such neuronal commands take the form of action potentials that travel from the brain to the5 muscle fibres in several steps. The neuromuscular junction (NMJ) is a highly

specialized membrane area on muscle fibres where motor neurons come into close contact with the muscle fibres, and it is at the NMJ where neuronal action potentials are transmitted to muscular action potentials in a one-to-one fashion via synaptic

transmission.

0

Neuromuscular transmission refers to the sequence of cellular events at the NMJ whereby an action potential in the lower motor neuron is transmitted to a corresponding action potential in a muscle fibre (Wood SJ, Slater CR. Safety factor at the

neuromuscular junction. Prog. Neurobiol. 2001 , 64, 393-429). When a neuronal action5 potential arrives at the pre-synaptic terminal it triggers influx of Ca 2+ through voltage

gated P/Q-type Ca 2+ channels in the nerve terminal membrane. This influx causes a rise in cytosolic Ca 2+ in the nerve terminal that triggers exocytosis of acetylcholine

(ACh). Released ACh next diffuses across the synaptic cleft to activate nicotinic ACh receptors in the post-synaptic, muscle fibre membrane. Upon activation, ACh

0 receptors convey an excitatory current flow of Na + into the muscle fibre, which results in a local depolarization of the muscle fibre at the NMJ that is known as the endplate potential (EPP). If the EPP is sufficiently large, voltage gated Na + channels in the muscle fibre will activate and an action potential in the muscle fibre will ensue. This action potential then propagates from the NMJ throughout the muscle fibre and triggers release of Ca 2+ release from the sarcoplasmic reticulum. The released Ca 2+ activates the contractile proteins within the muscle fibres, thus resulting in contraction of the fibre.

Failure of neuromuscular transmission can arise from both pre-synaptic dysfunction [Lambert Eaton syndrome (Titulaer MJ, Lang B, Verschuuren JJ. Lambert-Eaton myasthenic syndrome: from clinical characteristics to therapeutic strategies. Lancet Neurol. 2011 , 10, 1098-107), amyotrophic lateral sclerosis (Killian JM, Wilfong AA, Burnett L, Appel SH, Boland D. Decremental motor responses to repetitive nerve stimulation in ALS. Muscle Nerve, 1994, 17, 747-754), spinal muscular atrophy (Wadman Rl, Vrancken AF, van den Berg LH, van der Pol WL. Dysfunction of the neuromuscular junction in spinal muscular atrophy types 2 and 3. Neurology, 2012, 79, 2050-2055) and as a result of post-synaptic dysfunction as occurs in myasthenia gravis (Le Panse R, Berrih-Aknin S. Autoimmune myasthenia gravis: autoantibody

mechanisms and new developments on immune regulation. Curr Opin Neurol., 2013, 26, 569-576)]. Failure to excite and/or propagate action potentials in muscle can also arise from reduced muscle excitability such as in critical illness myopathy (CIM) (Latronico, N., Bolton, C.F. Critical illness polyneuropathy and myopathy: a major cause of muscle weakness and paralysis. Lancet Neurol. 2011 , 10, 931-941). In Lambert Eaton syndrome, an autoimmune attack against the pre-synaptic P/Q-type Ca 2+ channels results in markedly reduced Ca 2+ influx into the nerve terminal during the pre-synaptic action potential and consequently a reduced release of ACh into the synaptic cleft. In myasthenia gravis, the most common finding is an autoimmune attack on the post-synaptic membrane either against the nicotinic ACh receptors or the musk- receptor in the muscle fibre membrane. Congenital forms of myasthenia are also known. Common to disorders with neuromuscular transmission failure (Lambert Eaton syndrome, amyotrophic lateral sclerosis, spinal muscular atrophy and myasthenia gravis) is that the current flow generated by ACh receptor activation is markedly reduced, and EPPs therefore become insufficient to trigger muscle fibre action potentials.

Neuromuscular blocking agents also reduce EPP by antagonizing ACh receptors. In CIM with reduced muscle excitability, the EPP may be of normal amplitude but they are still insufficient to trigger muscle fibre action potentials because the membrane potential threshold for action potential excitation has become more depolarized because of loss of function of voltage gated Na + channels in the muscle fibres.

While ACh release (Lambert Eaton, amyotrophic lateral sclerosis, spinal muscular atrophy), ACh receptor function (myasthenia gravis, neuromuscular blockade) and function of voltage gated Na + channels (CIM) are essential components in the synaptic transmission at NMJ, the magnitude of the EPP is also affected by inhibitory currents flowing in the NMJ region of muscle fibres. These currents tend to outbalance excitatory current through ACh receptors and, expectedly, they thereby tend to reduce EPP amplitude. The most important ion channel for carrying such inhibitory membrane currents in muscle fibres is the muscle-specific CIC-1 Cl ion channel (Kwiecihski H, Lehmann-Horn F, Rudel R. Membrane currents in human intercostal muscle at varied extracellular potassium. Muscle Nerve. 1984, 7, 465-469; Kwiecihski H, Lehmann-Horn F, Rudel R. Drug-induced myotonia in human intercostal muscle. Muscle Nerve. 1988, 11, 576-581 ; Pedersen, T.H., F. de Paoli, and O.B. Nielsen. Increased excitability of acidified skeletal muscle: role of chloride conductance. J. Gen. Physiol., 2005, 125, 237-246).

ACh esterase (AChE) inhibitors are traditionally used in the treatment of myasthenia gravis. This treatment leads to improvement in most patients but it is associated with side effects, some of which are serious (Mehndiratta MM, Pandey S, Kuntzer T.

Acetylcholinesterase inhibitor treatment for myasthenia gravis. Cochrane Database Syst Rev. 2014, Oct 13; 10). Because ACh is an import neurotransmitter in the autonomic nervous system, delaying its breakdown can lead to gastric discomfort, diarrhoea, salivation and muscle cramping. Overdosing is a serious concern as it can lead to muscle paralysis and respiratory failure, a situation commonly referred to as cholinergic crisis. Despite the serious side effects of AChE inhibitors, these drugs are today the treatment of choice for a number of disorders involving neuromuscular impairment. In patients where pyridostigmine (a parasympathomimetic and a reversible AChE inhibitor) is insufficient, corticosteroid treatment (prednisone) and

immunosuppressive treatment (azathioprine) is used. Plasma exchange can be used to obtain a fast but transient improvement. Unfortunately, all of the currently employed drug regimens for treatment of myasthenia gravis are associated with deleterious long-term consequences (Howard, J.F. Jr.

Adverse drug effects on neuromuscular transmission. Semin Neurol. 1990, 10, 89 - 102) despite research to identify new treatments (Gilhus, N.E. New England Journal of Medicine, 2016, 375, 2570-2581).

The CIC-1 ion channel (Pedersen, T.H., Riisager, A., Vincenzo de Paoli, F., Chen, T-Y, Nielsen, O.B. Role of physiological CIC-1 Cl ion channel regulation for the excitability and function of working skeletal muscle. J. Gen. Physiol. 2016, 147, 291 - 308) is emerging as a target for potential drugs, although its potential has been largely unrealised.

Summary

The present disclosure comprises a new series of compounds that alleviate disorders of the neuromuscular junction through inhibition of CIC-1 channels.

It has been found that a set of compounds that inhibit CIC-1 ion channels are capable of restoring neuromuscular transmission, as evidenced by the data generated by investigation of the compound set in biological models described herein. Compounds of the disclosure thus constitute a new group of potential drugs that can be used to treat or ameliorate muscle weakness and muscle fatigue in neuromuscular junction disorders caused by disease or by neuromuscular blocking agents.

The present disclosure thus concerns the discovery of CIC-1 ion channel inhibitors with application in the treatment of a range of conditions, such as reversal of block, ALS and myasthenic conditions, in which muscle activation by the nervous system is

compromised and symptoms of weakness and fatigue are prominent.

Description of Drawings

Figure 1. Panel A shows a schematic representation of the positioning of the three microelectrodes (Vi, V2 and V3) when inserted in a single skeletal muscle fibre for G m determination. Please note that the drawing illustrates only the impaled fibre although it is part of an intact muscle that contains many such fibres. All electrodes recorded the membrane potential of the fibre and the two peripheral electrodes were used to inject current (-30 nA, 50 ms). The electrodes were inserted with known inter-electrode distances (Xi, X2 and X3). After insertion, current was passed first via the Vi electrode and then via the V3 electrode. The resulting deflections in the membrane voltage were measured by the other electrodes. The steady state deflections in membrane potential were measured and divided by the magnitude of the injected current (-30 nA) to obtain transfer resistances. These were next plotted against inter-electrode distances, and fitted to an exponential function (Panel B), from which G m could be calculated using linear cable theory. The approach described in panel A and B, was repeated for several muscle fibres in the muscle during exposure at increasing concentrations of compound E-8, with approx. 10 fibres at each concentration. Average G m at each concentration was plotted as a function of compound concentration in panel C, and fitted to a 4- parameter sigmoidal function from which the EC50 value for the compound was obtained (dashed line)

Figure 2. Panel A shows representative force traces before and after exposure to compound E-8. Force traces from a representative muscle stimulated to contract in 1) control condition before addition of neuromuscular blocking agent, 2) the force response to stimulation after 90 minutes incubation with Tubocurarine. Here the muscle displays severe neuromuscular transmission impediment, and 3) The muscle force response after addition of 50 mM compound E-8. Panel B shows average force (AUC) from 3 muscles relative to their initial force. The traces presented in panel A (1 , 2, 3), correspond to the dotted lines in panel B, respectively. Thus, force is lost due to 90 min incubation in tubocurarine and is subsequently recovered when compound E-8 is added.

Figure 3: Panel A illustrates the voltage protocol used to evoke currents in whole cell patches of CHO cells expressing human CIC-1 channels. Panel B shows

representative whole cell current traces from a patched CHO cell expressing human CIC-1 channels. Currents were evoked by applying the voltage protocol shown in Panel A.

Figure 4: Panel A shows a representative l/V plot of constant current density in a CIC- 1 expressing CHO cell before (circles) and after (squares) application of 100 mM of the CIC-1 inhibitor, 9-anthracenecarboxylic acid (9-AC, Sigma A89405). Panel B shows a l/V plot of instant tail current density from the same CIC-1 expressing CHO cell as illustrated in Panel A, before (circles) and after (squares) application of 100 pM 9-AC. Figure 5: Figure 5 shows representative plots of normalized instant tail currents from a CIC-1 expressing CHO cell patch before (circles) and after (squares) application of 100 pM 9-AC. The instant tail currents at each voltage step were normalized to the maximal tail current obtained following the (+)120 mV voltage step and fitted to a Boltzmann function to determine the half activation potential, V1 / 2.

Neuromuscular disorders

The compound or compound for use of the present disclosure is used for treating, ameliorating and/or preventing a neuromuscular disorder, or reversing neuromuscular blockade caused by non-depolarizing neuromuscular blocker or antibiotic agent.

The inventors of the present disclosure have shown that inhibition of CIC-1 channels strengthens neuromuscular transmission. CIC-1 function may therefore contribute to muscle weakness in conditions of compromised neuromuscular transmission.

Thus, in one embodiment of the present invention, the compound or the compound for use as described herein inhibits CIC-1 channels. Thus, it is appreciated that

compounds and/or compounds for use of Formula (I) inhibit CIC-1 channels.

The neuromuscular disorder may also include neuromuscular dysfunctions.

Neuromuscular disorders include for example disorders with symptoms of muscle weakness and fatigue. Such disorders may include conditions with reduced

neuromuscular transmission safety factor. In one embodiment the neuromuscular disorders are motor neuron disorders. Motor neuron disorders are disorders with reduced safety in the neuromuscular transmission. In one embodiment motor neuron disorders are selected from the group consisting of amyotrophic lateral sclerosis (ALS) (Killian JM, Wilfong AA, Burnett L, Appel SH, Boland D.

Metab., 2012, 15, E551 - 561) and sarcopenia (Gilmore K.J.,

Morat T., Doherty T.J., Rice C.L., Motor unit number estimation and neuromuscular fidelity in 3 stages of sarcopenia. 2017, 55(5):676-684).

Thus, in one embodiment of the present disclosure the neuromuscular disorder is amyotrophic lateral sclerosis (ALS). In another embodiment the neuromuscular disorder is spinal muscular atrophy (SMA). In another embodiment the neuromuscular disorder is Charcot-Marie tooth disease (CMT). In another embodiment the

neuromuscular disorder is sarcopenia. In yet another embodiment, the neuromuscular disorder is critical illness myopathy (CIM).

As stated above the neuromuscular disorders include for example disorders with symptoms of muscle weakness and fatigue. Such disorder may for example include diabetes (Burton, A. Take your pyridostigmine: that's an (ethical?) order! Lancet Neurol., 2003, 2, 268).

In one embodiment the compound or the compound for use of the present disclosure is used to prevent neuromuscular disorder. The compound or the compound for use may for example be used prophylactically against nerve gas that is known to cause symptoms of muscle weakness and fatigue (Kawamura, Y., Kihara, M., Nishimoto, K., Taki, M. Efficacy of a half dose of oral pyridostigmine in the treatment of chronic fatigue syndrome: three case reports. Pathophysiology, 2003, 9, 189-194). In one embodiment the compound or the compound for use of the present disclosure is used in the treatment of botulism poisoning (Sellin, L.C., The action of botulinum toxin at the neuromuscular junction, Med Biol., 1981 , 59, 11-20. In one disclosure, the compound or the compound for use of the present disclosure is used in the treatment of snake bites (Silva A., Maduwage K., Buckley N.A., Lalloo D.G., de Silva H.J., Isbister G.K., Antivenom for snake venom-induced neuromuscular paralysis, Cochrane Database of Systematic Reviews, 2017, 3, Art. No.: CD012604).

In another embodiment the neuromuscular disorders is chronic fatigue syndrome. Chronic fatigue syndrome (CFS) (Fletcher, S.N., Kennedy, D.D., Ghosh, I.R., Misra, V.P., Kiff, K., Coakley, J.H., Hinds, C.J. Persistent neuromuscular and

neurophysiologic abnormalities in long-term survivors of prolonged critical illness. Crit. Care Med. 2003, 31, 1012 - 1016) is the common name for a medical condition characterized by debilitating symptoms, including fatigue that lasts for a minimum of six months in adults. CFS may also be referred to as systemic exertion intolerance disorder (SEID), myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS), chronic fatigue immune dysfunction syndrome (CFIDS), or by several other terms. Symptoms of CFS include malaise after exertion; unrefreshing sleep, widespread muscle and joint pain, physical exhaustion, and muscle weakness.

In another embodiment the neuromuscular disorder is myotubular myopathy (Dowling, J.J. et al, Myotubular myopathy and the neuromuscular junction:

a novel therapeutic approach from mouse models, Disease Models & Mechanisms, 2012, 5, 852-859). In another embodiment the neuromuscular disorder is Duchenne muscular dystrophy (van der Pijl, M.M. et al, Characterization of neuromuscular synapse function abnormalities in multiple Duchenne muscular dystrophy mouse models, European Journal of Neuroscience, 2016, 43, 1623-1635.

In a further embodiment the neuromuscular disorder is a critical illness polyneuropathy (Angelini C. Spectrum of metabolic myopathies. Biochim. Biophys. Acta., 2015, 1852, 615 - 621) or CIM (Latronico, N., Bolton, C.F. Critical illness polyneuropathy and myopathy: a major cause of muscle weakness and paralysis. Lancet Neurol. 2011 , 10, 931-941). Critical illness polyneuropathy and CIM are overlapping syndromes of widespread muscle weakness and neurological dysfunction developing in critically ill patients.

The neuromuscular disorder may also include metabolic myopathy (Milone, M., Wong, L.J. Diagnosis of mitochondrial myopathies. Mol. Genet. Metab., 2013, 110, 35 - 41) and mitochondrial myopathy (Srivastava, A., Hunter, J.M. Reversal of neuromuscular block. Br. J. Anaesth. 2009, 103, 115 - 129). Metabolic myopathies result from defects in biochemical metabolism that primarily affects muscle. These may include glycogen storage disorders, lipid storage disorder and 3-phosphocreatine storage disorder. Mitochondrial myopathy is a type of myopathy associated with mitochondrial disorder. Symptoms of mitochondrial myopathies include muscular and neurological problems such as muscle weakness, exercise intolerance, hearing loss and trouble with balance and coordination.

In another embodiment the neuromuscular disorder is periodic paralysis, in particular hypokalemic periodic paralysis which is a disorder of skeletal muscle excitability that presents with recurrent episodes of weakness, often triggered by exercise, stress, or carbohydrate-rich meals (Wu, F., Mi, W., Cannon, S.C., Neurology, 2013, 80, 11 IQ- 1116 and Suetterlin, K. et at, Current Opinion Neurology, 2014, 27, 583-590) or hyperkalemic periodic paralysis which is an inherited autosomal dominant disorder that affects sodium channels in muscle cells and the ability to regulate potassium levels in the blood (Ammat, T. et at, Journal of General Physiology, 2015, 146, 509-525).

In an embodiment the neuromuscular disorder is a myasthenic condition. Myasthenic conditions are characterized by muscle weakness and neuromuscular transmission failure. Congenital myasthenia gravis (Finlayson, S., Beeson, D., Palace, J. Congenital myasthenic syndromes: an update. Pract. Neurol., 2013, 13, 80 - 91) is an inherited neuromuscular disorder caused by defects of several types at the neuromuscular junction.

Myasthenia gravis and Lambert-Eaton syndrome (Titulaer MJ, Lang B, Verschuuren JJ. Lambert-Eaton myasthenic syndrome: from clinical characteristics to therapeutic strategies. Lancet Neurol. 2011 , 10, 1098-107) are examples of myasthenic conditions. Myasthenia gravis is either an autoimmune or congenital neuromuscular disorder that leads to fluctuating muscle weakness and fatigue. In the most common cases, muscle weakness is caused by circulating antibodies that block ACh receptors at the postsynaptic neuromuscular junction, inhibiting the excitatory effects of the

neurotransmitter ACh on nicotinic ACh-receptors at neuromuscular junctions (Gilhus, N.E., Owe, J.F., Hoff, J.M., Romi, F., Skeie, G.O., Aarli, J.A. Myasthenia Gravis: A Review of Available Treatment Approaches, Autoimmune Diseases, 2011 , Article ID 84739). Lambert-Eaton myasthenic syndrome (also known as LEMS, Lambert-Eaton syndrome, or Eaton-Lambert syndrome) is a rare autoimmune disorder that is characterized by muscle weakness of the limbs. It is the result of an autoimmune reaction in which antibodies are formed against presynaptic voltage-gated calcium channels, and likely other nerve terminal proteins, in the neuromuscular junction.

Thus, in one embodiment of the present disclosure the neuromuscular disorder is myasthenia gravis. In another embodiment the neuromuscular disorder is Lambert- Eaton syndrome.

Neuromuscular blockade is used in connection with surgery under general

anaesthesia. Reversing agents are used for more rapid and safer recovery of muscle function after such blockade. Complications with excessive muscle weakness after blockade during surgery can result in delayed weaning from mechanical ventilation and respiratory complications after the surgery. Since such complications have pronounced effects on outcome of the surgery and future quality of life of patients, there is a need for improved reversing agents (Murphy GS, Brull SJ. Residual neuromuscular block: lessons unlearned. Part I: definitions, incidence, and adverse physiologic effects of residual neuromuscular block. Anesth Analg. 2010 111 (1): 120-8). Thus, in one embodiment, the neuromuscular disorder has been induced by a neuromuscular blocking agent. In one particular embodiment the neuromuscular disorder is muscle weakness caused by neuromuscular blockade after surgery. In another embodiment of the present disclosure the compound or the compound for use is used for reversing and/or ameliorating neuromuscular blockade after surgery. In one embodiment, the neuromuscular blockade is drug induced. In one embodiment the neuromuscular blockade is induced by an antibiotic. In one embodiment the neuromuscular blockade is induced by a non-depolarizing neuromuscular blocker.

General synthetic strategies

Compounds of formula (I) may be synthesized by the following general methods:

General Method A

(GM.I) (GM.II) (GM.III) (GM.IV)

Method A involves the synthesis of compounds of formula (GM.IV), which is an aryloxyalkyl-substituted tetrazole derivative, and -R 1 , -R 2 , -R 3 , -R 4 and n are as defined in Formula (I) above. Compound (GM.I), wherein -Z represents a group, for example a carboxylic acid functionality, that can be converted into a primary amide by a range of reaction conditions, is available either commercially or synthetically. Compound (GM.I) can be converted into a substituted ether of formula (GM.II) by methods which include the presence of ammonium chloride, a coupling agent such as hexafluorophosphate azabenzotriazole tetramethyl uranium (HATU) and a base such as triethylamine, as well as some two-step methods that include the formation of an amide with

dibenzylamine and subsequent conversion into a primary amide. The primary amide functionality in compound (GM.II) can be converted into the corresponding nitrile (GM.III) under dehydrative conditions, including via the use of acetic anhydride, thionyl chloride or phosphorus oxychloride in a suitable solvent such as THF or 1 ,2- dichloroethane.

The nitrile (GM.III) can be readily converted into the target tetrazole derivative (GM.IV), typically by a cycloaddition reaction under a range of reaction conditions, utilising e.g. trimethylsilyl azide or an alkali metal azide.

Alternative methods involve the reaction of e.g. a suitably protected alcohol, e.g. a benzyl protected tetrazole-CH(R 4 )-OH, with a suitably substituted phenol wherein - R 1 , -R 2 , -R 3 and n are as defined above under Mitsunobu reaction conditions, followed by deprotection to provide the desired tetrazole derivative GM.IV.

Method B involves the synthesis of compound (GM.VII), an aryloxy-substituted hydroxamic acid ether derivative, wherein -R 1 , -R 2 , -R 3 , -R 4 , -R 14 , -R 15 and n are as defined in Formula (I) above. Compound (GM.V), wherein the group -W is a feasible carboxylic acid precursor, which can include an ester, an alcohol, a nitrile, including (GM.III), is available either commercially or synthetically. In the case of the acid precursor being a primary alcohol, it can be oxidised to a carboxylic acid under standard conditions involving potassium permanganate, Jones oxidation conditions, the Heyns oxidation, ruthenium tetroxide or TEMPO. Compound (GM.V) thereby provides varied and facile access to the substituted carboxylic acid (GM.VI), wherein -R 1 , -R 2 , - R 3 and -R 4 are as defined above. The target aryloxy substituted hydroxamic acid ether derivative (GM.VII) is readily obtained under reaction conditions that include a coupling procedure between the carboxylic acid (GM.VI), a suitable coupling agent, such as HATU, a suitable dialkylcarbodiimide derivative, or 2-chloro-/\/-methyl pyridinium iodide, and a hydroxylamine derivative of formula R 15 -0-NH-R 14 , with -R 14 and -R 15 as defined above, as a nucleophile. An alternative to a coupling reaction is reaction of e.g. the acid chloride derived from compound (GM.VI), by treatment with for example thionyl chloride, with a hydroxylamine derivative of formula R 15 -0-NH-R 14 in the presence of a suitable base, e.g. a trialkylamine.

General Method C

Method C involves the synthesis of compound (GM.VIII), an aryloxy-substituted N- cyano derivative, wherein -R 1 , -R 2 , -R 3 , -R 4 , -R 13 and n are as defined in Formula (I) above. Compound (GM.V), wherein the group -W is a feasible carboxylic acid precursor, which can include an ester, an alcohol, a nitrile, including (GM.III), is available either commercially or synthetically. In the case of the acid precursor being a primary alcohol, it can be oxidised to a carboxylic acid under standard conditions involving potassium permanganate, Jones oxidation conditions, the Heyns oxidation, ruthenium tetroxide or TEMPO. Compound (GM.V) thereby provides varied and facile access to the substituted carboxylic acid XVII, wherein -R 1 , -R 2 , -R 3 and -R 4 are as defined above. The target aryloxy substituted N-cyano derivative (GM.VIII) is readily obtained under reaction conditions that include a coupling procedure between the carboxylic acid (GM.VI), involving a suitable coupling agent, such as HATU, a suitable dialkylcarbodiimide derivative or 2-chloro-/\/-methyl pyridinium iodide, and e.g. a compound of formula R 13 -NH-CN, as a nucleophile, wherein R 13 is as defined above. An alternative to a coupling reaction is reaction of e.g. the acid chloride derived from compound (GM.VI), by treatment with for example thionyl chloride, with e.g. a compound of formula R 13 -NH-CN, as a nucleophile, wherein R 13 is as defined above, in the presence of a suitable base, e.g. a trialkylamine.

Example 9: Electrophysiological measurement of compound inhibition of CIC-1 in rat muscle

The investigatory goal of these experiments was to evaluate whether compounds inhibit CIC-1 channels in native tissue of rat skeletal muscle fibres. Apparent CIC-1 affinity was reported by the concentration of compound at which 50% of the

compound’s full inhibition of CIC-1 was observed (EC50).

CIC-1 Cl ion channels generate around 80% of the total membrane conductance (G m ) in resting skeletal muscle fibres of most animals including rat and human (Bretag, A H. Muscle chloride channels. Physiological Reviews, 1987, 67, 618-724). Other ion channels that contribute to G m can therefore be considered negligible, and it is possible to evaluate whether a compound inhibits CIC-1 in rat muscle by comparing G m measurements before and after exposure to a compound. CIC-1 inhibition would in such recordings be reflected by a reduction of G m . Experimentally, G m was measured in individual fibres of whole rat soleus muscles using a three micro-electrodes technique described in this example and in full detail elsewhere (Riisager ef a/., Determination of cable parameters in skeletal muscle fibres during repetitive firing of action potentials. Journal of Physiology, 2014, 592, 4417- 4429). Briefly, intact rat soleus muscles were dissected out from 12-14 week old Wistar rats and placed in an experimental chamber that was perfused with a standard Krebs Ringer solution containing 122 mM NaCI, 25 mM NaHCC>3, 2.8 mM KCI, 1.2 mM KH2PO4, 1.2 mM MgSCU, 1.3 mM CaCh, 5.0 mM D-glucose. During experiments, the solution was kept at approx. 30°C and continuously equilibrated with a mixture of 95% O2 and 5% CO2, pH ~7.4. The experimental chamber was placed in Nikon upright microscope that was used to visualize individual muscle fibres and the three electrodes (glass pipettes filled with 2 M potassium citrate). For G m measurements, the electrodes were inserted into the same fibre with known inter-electrode distances of 0.35 - 0.5 mm (V1-V2, X1) and 1.1-1.5 mm (V1-V3, X3) (Figure 1A). The membrane potential of the impaled muscle fibre was recorded by all electrodes. Two of the electrodes were furthermore used to inject 50 ms current pulses of -30 nA. Given the positions of the electrodes, three different inter-electrode distances could be identified (X1-X2, X1-X3, X2-X3) and hence the membrane potential responses to the current injections could be obtained at three distances from the point of current injection. The steady state voltage deflection at each distance was divided by the magnitude of current injected (-30 nA) and the resulting transfer resistances were plotted against inter-electrode distance and the data was fitted to a mono-exponential function from which G m could be calculated using linear cable theory (Figure 1 B).

To establish a dose response relationship, G m was first determined in 10 muscle fibres in the absence of compound and then at four increasing compound concentrations with G m determinations in 5-10 fibres at each concentration. The average G m values at each concentration were plotted against compound concentration and the data was fitted to sigmoidal function to obtain an EC50 value (Figure 1 C). Table 2 shows the EC50 values for a range of compounds with n values referring to number of experiments that each reflect recordings from around 50 fibres.

Example 10: Measurement of force in an in vitro model

The current disclosure relates to compounds that inhibit CIC-1 ion channels and increase muscle excitability and thereby improve muscle function in clinical conditions where muscle activation is failing. Such conditions result in loss of contractile function of skeletal muscle, weakness and excessive fatigue. In this series of experiments the compounds were tested for their ability to restore contractile function of isolated rat muscle when the neuromuscular transmission had been compromised akin to neuromuscular disorders.

Experimentally, soleus muscles from 4-5 week old rats were isolated with the motor nerve remaining attached. The nerve-muscle preparations were mounted in experimental setups that enabled electrical stimulation of the motor nerve. Stimulation of the motor nerve led to activation of the muscle fibres and ensuing force production that was recorded. The nerve-muscle preparations were also in these experiments incubated in the standard Krebs Ringer (see example 5) and the solution was heated to 30°C and continuously equilibrated with a mixture of 95% O2 and 5% CO2, pH ~7.4.

After mounting the nerve-muscle preparation in the experimental setup, the contractile function of the muscle was initially assessed under the control conditions (Figure 2A). Sub-maximal concentration of tubocurarine (115 nM), an acetylcholine receptors antagonist, was then added to the experimental bath to impose partial inhibition of the ability of the motor nerve to activate the muscle fibres. The experimental condition mimics the failing neuromuscular transmission in a range of neuromuscular disorders. After addition of tubocurarine the contractile force declined over the next 90 mins to IQ- 50 % of the control force. 50 mM of the test compound was then added and the contractile force recovered despite the continued presence of tubocurarine. To quantify the ability of the compound to restore force the percentage of the initial force that was restored was determined after 40 mins of compound exposure (Figure 2B) and the point increase is reported in Table 3.

Table 3: Percentage increase of initial force that was restored

In conclusion, this example demonstrates that the compounds of the present disclosure are able to increase muscle excitability and thereby improve muscle function in clinical conditions.

Example 11 : Screening of compounds on the human isoform of CIC-1 expressed in CHO cells using automated patch-clamp

The investigatory goal of these experiments was to evaluate how compounds affect the open probability and current amplitude of human CIC-1 channels expressed in CHO cells. Experiments were performed using an automated patch clamp system that allowed high throughput testing of whole cell patches together with both intracellular and extracellular addition of compound.

Automated voltage clamp measurements

Automated whole cell patch clamp experiments were performed with the Qpatch 16 system (Sophion Bioscience, Ballerup, Denmark) at room temperature. Data acquisition and analysis were performed in the Qassay software (ver. 5.6, Odense).

Voltage protocol and analysis of whole cell CIC-1 currents

To evoke CIC-1 currents in whole cell patches, the membrane potential was initially stepped from a holding potential of -30 mV to +60 mV for 100 ms and then to various test voltages (sweeps) ranging from +120 mV to -140 mV in steps of 20 mV for 300 ms. To obtain tail currents, the membrane potential was stepped to -100 mV after each test voltage for 300 ms and then relaxed to -30 mV for 2 sec between sweeps (Figure 3). l/V relationships for whole cell instant and steady state current amplitudes were obtained by plotting average current densities at the beginning and at the end of the 300 s step against the membrane potential (Figure 4).

In order to determine the relative overall open probability (Po), the instantaneous tail currents were normalized to the maximal tail current obtained following the most positive voltage step and plotted against the test voltage. Plots of normalized tail currents from each whole cell patch were then fitted to a Boltzmann function allowing determination of half activation voltages (V1 / 2, Figure 5).

Solutions

For automated patch clamp experiments extracellular solutions contained: 2 mM CaCI 2 , 1 mM MgCI 2 , 10 mM HEPES, 4 mM KCI, 145 mM NaCI, 10 mM Glucose, pH adjusted to 7.4 with NaOH (2 M). Osmolality adjusted to -320 using sucrose.

Intracellular solutions contained: 80 mM CsF, 60 mM CsCI, 5/1 mM KOH/EGTA, 10 mM HEPES, 10 mM NaCI, pH adjusted to 7.2 with NaOH (2 M). Osmolality adjusted to -320 mOsm using sucrose.

Cell line information:

Cells used in patch clamp experiments were Chinese hamster ovary cells (CHO) constitutively expressing human CIC-1 channels. The amino acid sequence encoded by the cDNA used to create this cell line was identical to the translated sequence for GenBank accession number NM_000083.2. Cells were produced by Charles River (Catalogue CT6175, Cleveland OH, USA) in a cryopreserved format. Experiments were performed on the cells directly after thawing (3 x 10 6 cells used in each experiment).

Test protocol

To evaluate the compound effect on CIC-1 , when applied directly to the intracellular side of the cell membrane, the half activation voltage, V1 / 2, was determined from whole cell patches with compound added to the intracellular solution and then compared to V1/2 determined from control cell patches with only vehicle added to the intracellular solution. Additionally, the effect of extracellular added compound was evaluated by determine V1/2 and steady state current amplitudes before and after exchanging the extracellular solution to contain compound.

The difference in half activation voltage of CIC-1 channels, D\L /2 , was determined as the difference between the cell patches treated intracellularly with compound and control cells patches and is reported in Table 4 below. A positive shift in D L/2 is reflecting CIC-1 channel inhibition by the tested compound. P-values of <0.05 is considered significant.

Example 12: Measurement of In Situ Muscle Contractile Characteristics

Isometric hindlimb force was measured in 12-week old female Lewis rats in the presence and absence of compound.

Rats were placed under anesthesia with isoflurane (2-4%), intubated and subsequently connected to a micro ventilator (Microvent 1 , Hallowell EMC, US). Two stimulation electrodes were inserted through the skin to stimulate the sciatic nerve. A small incision was made proximal to the ankle, to expose the Achilles tendon, which was tied by cotton string, and connected to a force transducer (Fort250, World Precision

Instruments) with adjustable position (Vernier control). The Achilles tendon was then cut distal to the attached cotton string. The rat was placed on a heated pad, and to prevent movement artefacts from contraction of the ankle dorsiflexors, the foot was fixated by tape on a footplate.

Muscle contractile properties were assessed by applying an electrical current (under supramaximal voltage conditions) to the nerve and recording the force generated by the muscle. The muscle was stretched until maximal force was obtained, when assessed by 2 Hz stimulation. Isometric force was measured every 30 seconds at 12 Hz (Twitch), 10 pulses, and at every 5 minutes at 80 Hz (Tetanic) for 1 second (80 pulses). This stimulation pattern was employed throughout the experiment, expect in few cases where 80 Hz stimulation was replaced by 12 Hz (10 pulses). Neuromuscular transmission was partially inhibited by constant infusion of Cisatracurium (Nimbex, GlaxoSmithKline) at a concentration of 0.1 g/kg at an adjustable infusion speed, adjusted individually for each animal to obtain a level of inhibition of ca. 50% of the forced generated at 12 Hz stimulation on the 4 th pulse. When the level of

neuromuscular inhibition was stable, the test article was injected i.v. at the chosen concentration. The effect of test article was assessed on its ability to increase force generated from the stimulation pattern applied. The effect was assessed in the ability to increase force per se (tetanic, 80 Hz, stimulation), and the ratio between individual twitch peaks (12 Hz stimulation). The effect was monitored for at least 1 hour after injection of test article. In addition, the time from injection of test article to maximal effect on force (both twitch and tetanic) was noted and the time for the effect to disappear (return to baseline), if possible. When appropriate the infusion of

neuromuscular blocking agent was ceased, with the stimulation pattern continued, and the return of force to control levels was monitored. Animals were sacrificed by cervical dislocation while still fully sedated.

Compound E-8 was dosed 21.6 mg/kg i.v. resulting in an increase in tetanic force of 1 1 %. This demonstrates that compounds of the invention, such as Compounds E-8, can restore force to muscles in vivo which have been partially inhibited by a

neuromuscular blocker.
