Description

Substituted indoline and indole derivatives Field of the invention The present invention relates to novel substituted indole and indoline derivatives being openers of the KCNQ family potassium ion channels. The compounds are useful for the prevention, treatment and inhibition of disorders and diseases being responsive to opening of the KCNQ family potassium ion channels, one such disease is epilepsy.
Background of the invention Ion channels are cellular proteins that regulate the flow of ions, including potassium, calcium, chloride and sodium into and out of cells. Such channels are present in all animal and human cells and affect a variety of processes including neuronal transmission, muscle contraction, and cellular secretion.
Humans have over 70 genes encoding potassium channel subtypes (Jentsch Nature Reviews Neuroscience 2000, 1, 21-30) with a great diversity with regard to both stucture and function. Neuronal potassium channels, which are found in the brain, are primarily responsible for maintaining a negative resting membrane potential, as well 2o as controlling membrane repolarisation following an action potential.
One subset of potassium channel genes is the KCNQ family. Mutations in four out of five KCNQ genes have been shown to underlie diseases including cardiac arrhythmias, deafiiess and epilepsy (Jentsch Nature Reviews Neuroscience 2000, 1, 21-30).
The KCNQ4 gene is thought to encode the molecular correlate of a potassium channel found in outer hair cells of the cochlea and in Type I hair cells of the vestibular apparatus, in which, mutations can lead to a form of inherited deafiiess.
KCNQ1 (KvLQTl) is co-assembled with the product of the KCNE1 (miumal K(+)_ channel protein) gene in the heart to form a cardiac-delayed rectifier-lilce K(+) current. Mutations in this channel can cause one form of inherited long QT
syndrome type 1 (LQT1), as well as being associated with a form of deafness (Bobbins Phaf°macol TZaeY 2001, 90, 1-19).
The genes KCNQ2 and KCNQ3 were discovered in 1988 and appear to be mutated in an inherited form of epilepsy l~nown as benign familial neonatal convulsions (Rogawslci Trends in Neu~osciences 2000, 23, 393-398). The proteins encoded by the KCNQ2 and KCNQ3 genes are localised in the pyramidal neurons of the human cortex and hippocampus, regions of the brain associated with seizure generation and propagation (Cooper et al. Proceedings National Academy of Science U S A 2000, 97, 4914-4919).
KCNQ2 and KCNQ3 are two potassium channel subunits that form "M-currents"
when expressed in vitro. The M-current is a non-inactivating potassium current found in many neuronal cell types. In each cell type, it is dominant in controlling membrane excitability by being the only sustained current in the range of action potential initiation (Marrion Ayanual Review Physiology 1997, 59, 483-504). Modulation of the M-curl ent has dramatic effects on neuronal excitability, for example activation of the current will reduce neuronal excitability. Openers of these KCNQ channels, or activators of the M-current, will reduce excessive neuronal activity and may thus be 2o of use in the treatment, prevention or inhibition of seizures and other diseases and disorders characterised by excessive neuronal activity, such as neuronal hyperexcitability including convulsive disorders, epilepsy and neuropathic pain.
Retigabine (D-23129; N-(2-amino-4-(4-fluorobenzylamino)-phenyl) carbamic acid ethyl ester) and analogues thereof are disclosed in EP554543. Retigabine is an anti-convulsive compound with a broad spectrum and potent anticonvulsant properties, both in vitro and in vivo. It is active after oral and intraperitoneal administration in rats and mice in a range of anticonvulsant tests including: electrically induced seizures, seizures induced chemically by pentylenetetrazole, picrotoxin and N-methyl-3o D-aspartate (NMDA) and in a genetic animal model, the DBA/2 mouse (Rostocl~
et al.
Epilepsy Research 1996, 23, 211-223). In addition, retigabine is active in the amygdala lcindling model of complex partial seizures, further indicating that this compound has potential for anti-convulsive therapy. In clinical trials, retigabine has recently shown effectiveness in reducing the incidence of seizures in epileptic patients (Bialer et al. Epilepsy Research 2002, 51, 31-71).
Retigabine has been shown to activate a K(+) current in neuronal cells and the pharmacology of this induced current displays concordance with the published pharmacology of the M-channel, which recently was correlated to the KCNQ2/3 K(+) chamlel heteromultimer. This suggests that activation of KCNQ2/3 channels may be responsible for some of the anticonvulsant activity of this agent (Wiclcenden et al.
Molecular Pharmacology 2000, 58, 591-600) - and that other agents working by the to same mechanism may have similar uses.
KCNQ 2 and 3 channels have also been reported to be upregulated in models of neuropathic pain (Wickenden et al. Society for Neuroscience Abstracts 2002, 454.7), and potassium channel modulators have been hypothesised to be active in both neuropathic pain and epilepsy (Schroder et al. Neuropharmacology 2001, 40, 888-898).
Retigabine has also been shown to be beneficial in animal models of neuropathic pain (Blaclcburn-Munro and Jensen European Journal of Pharmacology 2003, 460, 109-116), and it is thus suggested that openers of KCNQ channels will be of use in treating pain disorders including neuropathic pain.
The localisation of KCNQ channel mRNA is reported in brain arid other central nervous system areas associated with pain (Goldstein et al. Society for Neuroscieh.ce Abstracts 2003, 53.8).
In addition to a role in neuropathic pain, the expression of mRNA for KCNQ 2-5 in the trigeminal and dorsal root ganglia and in the trigeminal nucleus caudalis implies that openers of these channels may also affect the sensory processing of migraine pain (Goldstein et al. Society for Neuroscience Abstracts 2003, 53.8).
Recent reports demonstrate that mRNA for KCNQ 3 and 5, in addition to that for KCNQ2, are expressed in astrocytes and glial cells. Thus KCNQ 2, 3 and 5 channels may help modulate synaptic activity in the CNS and contribute to the neuroprotective effects of KCNQ channel openers (Noda et al., Society fog Neuy-osciefZCe Abstracts 2003, 53.9).
Retigabine and other KCNQ modulators may thus exhibit protection against the neurodegenerative aspects of epilepsy, as retigabine has been shown to prevent limbic neurodegeneration and the expression of markers of apoptosis following kainic acid-induced status epilepticus in the rat (Ebert et al. Epilepsia 2002, 43 Suppl 5, 86-95).
This may have relevance for preventing the progression of epilepsy in patients, i.e. be 1o anti-epileptogenic. Retigabine has also been shown to delay the progression of hippocampal leindling in the rat, a further model of epilepsy development (Tober et al.
European Journal OfPharmacology 1996, 303, 163-169).
It is thus suggested that these properties of retigabine and other KCNQ
modulators may prevent neuronal damage induced by excessive neuronal activation, and may be of use in the treatment of neurodegenerative diseases, and be disease modifying (or antiepileptogenic) in patients with epilepsy.
Given that anticonvulsant compounds such as benzodiazepines and chlormetluazole 2o are used clincially in the treatment of the ethanol withdrawal syndrome and that other anticonvulsant compounds e.g. gabapentin, are very effective in animal models of this syndrome (Watson et al. Neuropha~macology 1997, 36, 1369-1375), other anticonvulsant compounds such as KCNQ openers are thus expected to be effective in this condition.
mRNA for KCNQ 2 and 3 subunits are found in brain regions associated with anxiety and emotional behaviours such as bipolar disorder e.g. hippocampus and amygdala (Saganich et al. .Iour~nal of Neuroscience 2001, 21, 4609-4624), and retigabine is reportedly active in some animal models of anxiety-like behaviour (Hartz et al.
.Tour-raal ofPsycl2oplaarmacology 2003, 17 suppl 3, A28,B16), and other clinically used anticonvulsant compounds are used in the treatment of bipolar disorder.

W001/022953 describes the use of retigabine for prophylaxis and treatment of neuropathic pain such as allodynia, hyperalgesic pain, phantom pain, neuropathic pain related to diabetic neuropathy and neuropathic pain related to migraine.
to W002/049628 describes the use of retigabine for the prevention, treatment, inhibition and amelioration of anxiety disorders such as anxiety, generalized anxiety disorder, panic a~zxiety, obsessive compulsive disorder, social phobia, performance anxiety, post-traumatic stress disorder, acute stress reaction, adjustment disorders, hypochondriacal disorders, separation anxiety disorder, agoraphobia and specific 15 phobias.
W097/15300 describes the use of retigabine for the treatment of neurodegenerative disorders such as Alzheimer's disease; Huntington's chorea; sclerosis such as multiple sclerosisand amyotrophic lateral sclerosis; Creutzfeld-Jakob disease;
Parkinson's 2o disease; encephalopathies induced by AIDS or infection by rubella viruses, herpes viruses, borrelia and unknown pathogens; trauma-induced neurodegenerations;

Indoles and indolines of the general formula XII and XIII substituted at position 4 or 6 with RZ-(U)S are commercially available, described in the literature or prepared according to methods known to chemists skilled in the art [R. J. Sundberg "Pyrroles 1o and their Benzo Derivatives: (iii) Synthesis and Applications" in Comprehensive Heterocyclic Chemistry, A. R. I~atritzky, C.W. Rees (Editors), vol. IV, pp 313-376, Pergamon Press, 1984]. Indoles of the general formula XII can be converted into indolines of the general formula XIII by methods known to chemists skilled in the art such as catalytic hydrogenation or reduction with NaBH3CN in appropriate solvents such as acetic acid [S. M. Bromidge, S. Dabbs, D. T. Davies, D. M. Duckworth, I. T.
Forties et al. J. Med. Chem. 41, 1998, 1598-1612]. Compounds of the general formula XII or XIII with s being 0 and R2 being in particular but not limited to substituted aryl or substituted heteroaryl as defined above can be prepared from corresponding compounds with R2 being I or Br by means of C-C coupling reactions known to 2o chemists skilled in the art, such as Suzuki coupling, Stille coupling, or other traalsition metal catalysed cross-coupling reactions [D.W. Knight "Coupling Reactions Between sp2 Carbon Centers" in Compreherasive Organic Synthesis, v. 3, pp. 481-520, Pergamon Press 1991].
Compounds of the general formula XIV are prepaxed by protection of the indoline nitrogen of the compounds of the general formula XIII with an appropriate protecting group (PGl) [Protective Groups in Organic Synthesis, 3rd Edition T. W. Greene, P. G.
M. Wuts, Wiley Interscience 1999], such as a trifluoroacetyl group known to chemists skilled in the art as TFA group, by reaction with the reagent forming the protective 3o group such as trifluoroacetic acid anhydride in a suitable solvent, such as 1,2-dichloroethane at appropriate temperatures.

The obtained compounds of the general formula XIV are converted into compounds of the general formula XV by regioselective nitration at position 5 of the indoline moiety by methods known to chemists skilled in the art [R. Behnisch "
Aromatische Nitro-Verbindungen" in Methoden den O~ganisch.e Chemiel(Houben-Weyl) p. 255, v.
El6d, Tlueme: 1992] such as reaction with concentrated nitric acid in appropriate solvent such as acetic anhydride, acetic acid, concentrated sulphuric acid or mixtures thereof at appropriate temperatures. The nitro compounds of the general formula XV

Alternatively, compounds of the general formula XIX are commercially available, described in the literature or can be prepared from compounds of the general formula XV by deprotection as described above. Then they are subjected to reductive allcylation with aldehydes of the general formula YCHO or to nucleophilic substitution reactions with electrophiles of the general formula (Y)(Rl)(Rl')C-LG as 3o described above, furnishing compounds of the general formula XX. Then the vitro group is reduced as described above forming compounds of the general formula XXI.
Finally, the compounds of the invention of the general formula I with indoline moiety are obtained by the method described above for the conversion of compounds of the general formula XVI into compounds of the general formula XVII.
Optionally, compounds of the invention of the general formula I with indole moiety 5 can be obtained from indolines of the general formula I by means of dehydrogenation known to chemists skilled in the art such as oxidation with appropriate reagents such as 2,3,5,6-tetrachloro-[1,4]benzoquinone, Mn02, or catalytic dehydrogenation in the presence of a catalyst such as Pd on charcoal or RuCl2(PPh3)3 in appropriate solvents such as toluene or xylene at appropriate temperatures.

15 5-Nitroindoline is protected with an appropriate protecting group, such as TFA group, as described above for compounds of the general formula XIV, furnishing compounds of the general formula XXII. Then the nitro group is reduced as described above for preparation of compounds of the general formula XVI, furnishing compounds of the general formula XXIII. They are converted into compounds of the general formula 2o XXIV with appropriate electrophiles forming R3-(Z)q-X as described above for compounds of the general formula XVII. Compounds of the general formula XXV
where s is 0 and R2 is NOZ or halogen such as Cl, Br or I, are obtained by means of regioselective electrophilic aromatic substitution, well known to chemists skilled in the art, with appropriate electrophiles such as N-chlorosuccinimide, bromine, iodine, 25 iodochloride in the appropriate solvent such as acetic acid or by nitration under conditions as described for compounds of the general formula XV.

This exemplifies a KCNQ2 screening protocol for evaluating compounds of the present invention. The assay measures the relative efflux through the KCNQ2 channel, and was carned out according to a method described by Tang et al.
(Tang, l0 W. et. al., J. Bioynol. Screen. 2001, 6, 325-331) for hERG potassium channels with the modifications described below.
An adequate number of CHO cells stably expressing voltage-gated KCNQ2 channels were plated at a density sufficient to yield a mono-confluent layer on the day of the 15 experiment. Cells were seeded on the day before the experiment and loaded with 1 ~Ci/ml [86Rb] over night. On the day of the experiment cells were washed with a HBSS-containing buffer. Cells were pre-incubated with drug for 30 minutes and the B~Rb+ efflux was stimulated by a submaximal concentration of 15 mM KCl in the continued presence of drug for additional 30 minutes. After a suitable incubation 2o period, the supernatant was removed and counted in a liquid scintillation counter (Tricarb). Cells were lysed with 2 mM NaOH and the amount of $6Rb+ was counted.
The relative efflux was calculated ((CPMsuper/(CPMsuper+ CPM~eII))~mpa/
(CPMsupen/(CPMsuper+ CPM~eII))lsr~~cc1)*100-100.
25 The compounds of the invention have an ECSO of less than 20000nM, in most cases less than 2000 nM and in many cases less than 200 nM. Accordingly, the compounds of the invention are considered to be useful in the treatment of diseases associated with the KCNQ family potassium channels.
3o Electrophysiological patch-clamp recordings.
Voltage-activated KCNQ2 currents were recorded from mammalian CHO cells by use of conventional patch-clamp recordings techniques in the whole-cell patch-clamp configuration (Hamill OP et.al. Pfliigers Arcla 1981; 391: 85-100). CHO cells with stable expression of voltage-activated KCNQ2 channels were grown under normal cell culture conditions in COZ incubators and used for electrophysiological recordings 1-7 days after plating. KCNQ2 potassium channels were activated by voltage steps up to + 80 mV in increments of 5-20 mV (or with a ramp protocol) from a membrane holding potential between -100 mV and - 40 mV (Tatulian L et al. JNeuroscience 2001; 21 (15): 5535-5545). The electrophysiological effects induced by the compounds were evaluated on various parameters of the voltage-activated KCNQ2 current. Especially effects on the activation threshold for the current and on the maximum induced current were studied.
to Some of the compounds of the invention have been tested in this test. A left-ward shift of the activation threshold or an increase in the maximum induced potassimn current is expected to decrease the activity in neuronal networks and thus make the compounds useful in diseases with increased neuronal activity - like epilepsia.
Maximum electroshock The test was conducted in groups of male mice using corneal electrodes and administering a square wave current of 26mA for 0.4 seconds in order to induce a convulsion characterised by a tonic hind limb extension (Wlaz et al. Epilepsy 2o Research 1998, 30, 219-229).
Pilocarpine induced seizures Pilocarpine induced seizures are induced by intraperitoneal injection of pilocarpine 250mg/lcg to groups of male mice and observing for seizure activity resulting in loss of posture within a period of 30 minutes (Stan et al. Pharmacology Biochemistry and Behavior' 1993, 45, 321-325).
Electrical seizure -threshold test A modification of the up-and-down method (Kimball et al. Radiatiofa Research 1957, 1-12) was used to determine the median threshold to induce tonic hind-limb extension in response to corneal electroshock in groups of male mice. The first mouse of each group received an electroshoclc at 14 mA, (0.4 s, 50 Hz) and was observed for seizure activity. If a seizure was observed the current was reduced by 1 mA for the next mouse, however, if no seizure was observed then the current was increased by 1 mA.
This procedure was repeated for all 15 mice in the treatment group.
Chemical seizure -threshold test The threshold dose of pentylenetetrazole required to induce a clonic convulsion was measured by timed infusion of pentylenetetrazole (Smg / mL at 0.5 mL/minute) into a lateral tail vein of groups of male mice (Nutt et al. JPharmacy and Pharmacology 1986, 38, 697-698).
1o Amygdala kindling Rats underwent surgery to implantation of tri-polar electrodes into the dorsolateral amygdala. After surgery the animals were allowed to recover before the groups of rats received either varying doses of test compound or the drug's vehicle. The animals were stimulated with their initial after discharge threshold + 25 p,A daily for 3-5 15 weeks and on each occasion seizure severity, seizure duration, and duration of electrical after discharge were noted. (Racine. Electroencephalography and Clinical Neuf°ophysiology 1972, 32, 281-294).
Side effects 2o Central nervous system side-effects were measured by measuring the time mice would remain on rotarod apparatus (Capacio et al. Drug ayad Claemical Toxicology 1992, 15, 177-201); or by measuring their locomotor activity by counting the number of infra-red beams crossed in a test cage (Watson et al. Neuroplaarnaacology 1997, 36, 1375). Hypothermic actions on the animals core body temperature of the compound 2s were measured by either rectal probe or implanted radiotelemetry transmitters capable of measuring temperature (Keeney et al. Physiology and Behaviour 2001, 74, 177-184).
Pharmacokinetics 3o The pharmacolcinetic properties of the compounds were determined via. i.v.
and p.o.
dosing to Sprague Dawley rats, and, thereafter, drawing blood samples over 20 hours.
Plasma concentrations were determined with LC/MS/MS.
