TECHNICAL FIELD OF THE INVENTION
The invention relates to compounds useful as inhibitors of sodium channels. The
invention also provides pharmaceutically acceptable compositions comprising the compounds of
the invention and methods of using the compositions in the treatment of various disorders
including pain.
BACKGROUND OF THE INVENTION
Pain is a protective mechanism that allows healthy animals to avoid tissue damage
and to t further damage to injured tissue. Nonetheless there are many conditions where pain
ts beyond its usefulness, or where patients would benefit from inhibition of pain.
athic pain is a form of chronic pain caused by an injury to the sensory nerves (Dieleman,
J.P., et al., Incidence rates and treatment of neuropathic pain conditions in the general tion.
Pain, 2008. 137(3): p. 681-8). Neuropathic pain can be divided into two categories, pain caused
by generalized metabolic damage to the nerve and pain caused by a discrete nerve injury. The
metabolic neuropathies include post herpetic neuropathy, diabetic neuropathy, and drug-induced
neuropathy. Discrete nerve injuries tions include post amputation pain, post-surgical nerve
injury pain, and nerve entrapment injuries like athic back pain.
Voltage-gated sodium channels (NaV’s) play a critical role in pain signaling.
NaV’s are key biological mediators of electrical ing as they are the primary mediators of the
rapid upstroke of the action potential of many excitable cell types (e.g. neurons, skeletal myocytes,
cardiac es). The evidence for the role of these ls in normal physiology, the
pathological states arising from mutations in sodium channel genes, preclinical work in animal
, and the clinical pharmacology ofknown sodium channel modulating agents all point to
the central role ofNaV’s in pain sensation (Rush, A.M. and TR. s, Painful Research:
fication ofa Small-Molecule Inhibitor that Selectively Targets NaV1.8 Sodium ls. Mol
Interv, 2007. 7(4): p. 192-5); England, 8., Voltage-gated sodium ls: the search for subtype-
selective analgesics. Expert Opin Investig Drugs 17 (12), p. 1849-64 (2008); Krafte, D. S. and
Bannon, A. W., Sodium channels and nociception: recent concepts and therapeutic opportunities.
Curr Opin Pharmacol 8 (1), p. 50-56 (2008)). NaV’s are the primary mediators of the rapid
upstroke of the action potential of many excitable cell types (e.g. neurons, skeletal myocytes,
cardiac myocytes), and thus are critical for the initiation of signaling in those cells (Hille, ,
Ion Channels OfExcz'table Membranes, Third ed. (Sinauer Associates, Inc., Sunderland, MA,
2001)). Because of the role NaV’s play in the initiation and propagation of neuronal signals,
antagonists that reduce NaV currents can prevent or reduce neural signaling and NaV channels
have long been considered likely targets to reduce pain in conditions where hyper-excitability is
observed (Chahine, M., Chatelier, A., Babich, 0., and Krupp, J. J., Voltage-gated sodium channels
in neurological disorders. CNS Neural Disord Drug Targets 7 (2), p. 144-58 (2008)). Several
clinically useful analgesics have been fied as inhibitors ofNaV channels. The local
anesthetic drugs such as lidocaine block pain by inhibiting NaV channels, and other compounds,
such as carbamazepine, lamotrigine, and tricyclic antidepressants that have proven effective at
reducing pain have also been ted to act by sodium channel inhibition (Soderpalm, B.,
Anticonvulsants: aspects of their mechanisms of action. Eur J Pain 6 Suppl A, p. 3-9 (2002);
Wang, G. K., Mitchell, J., and Wang, S. Y., Block of persistent late Na+ currents by antidepressant
sertraline and paroxetine. JMembr Biol 222 (2), p. 79-90 (2008)).
The NaV’s form a subfamily of the e-gated ion channel super-family and
ses 9 ms, designated Nav1.1 — Nav1.9. The tissue localizations of the nine isoforms
vary greatly. Nav1.4 is the primary sodium channel of skeletal muscle, and Nav1.5 is primary
sodium channel of cardiac myocytes. NaV’s 1.7, 1.8 and 1.9 are ily localized to the
peripheral nervous system, while NaV’s 1.1, 1.2, 1.3, and 1.6 are neuronal channels found in both
the central and peripheral nervous systems. The functional behaviors of the nine isoforms are
similar but distinct in the ics of their voltage-dependent and c behavior (Catterall, W.
A., Goldin, A. L., and Waxman, S. G., International Union of cology. XLVII.
Nomenclature and structure-function relationships of voltage-gated sodium channels. col
Rev 57 (4), p. 397 (2005)).
Immediately upon their discovery, NaV1.8 channels were identified as likely
targets for analgesia (Akopian, A.N., L. tti, and J.N. Wood, A tetrodotoxin-resistant voltage-
gated sodium l expressed by sensory neurons. Nature, 1996. 379(6562): p. 257-62). Since
then, NaV1.8 has been shown to be the most significant carrier of the sodium current that ins
action potential firing in small DRG neurons (Blair, NT. and B.P. Bean, Roles of otoxin
(TTX)-sensitive Na+ current, TTX-resistant Na+ current, and Ca2+ current in the action potentials
of nociceptive sensory s. J Neurosci., 2002. 22(23): p. 10277-90). NaV1.8 is essential for
spontaneous firing in damaged neurons, like those that drive neuropathic pain (Roza, C., et al., The
tetrodotoxin-resistant Na+ channel NaV1.8 is essential for the expression of spontaneous activity in
damaged sensory axons ofmice. J. Physiol., 2003. 550(Pt 3): p. 921-6; Jarvis, M.F., et al., A-

inflammatory pain in the rat. Proc Natl Acad Sci. U S A, 2007. 104(20): p. 8520-5; Joshi, S.K., et
al., Involvement of the TTX-resistant sodium channel Nav1.8 in inflammatory and neuropathic,but
not post-operative, pain states. Pain, 2006. 123(1-2): pp. 75-82; Lai, J., et al., Inhibition of
athic pain by decreased expression of the tetrodotoxin-resistant sodium channel, NaVl .8.

excitable nerves. M01 Pain, 2008. 4: p. 33; Black, J.A., et al., Multiple sodium channel isoforms

nerves. FEBS Lett, 2000. 467(2-3): p. ; ri, S., et al., Relationship of axonal voltage-
gated sodium channel 1.8 (NaVl .8) mRNA accumulation to sciatic nerve injury-induced painful
neuropathy in rats. J Biol Chem. 286(46): p. 39836-47). The small DRG neurons where NaV1.8 is
expressed include the nociceptors critical for pain signaling. NaV1.8 is the primary channel that
mediates large amplitude action potentials in small neurons of the dorsal root ganglia (Blair, NT.
and B.P. Bean, Roles of tetrodotoxin (TTX)-sensitive Na+ current, TTX-resistant Na+ t, and
Ca2+ current in the action potentials of nociceptive sensory neurons. JNeurosci., 2002. 22(23): p.
10277-90). Navl .8 is necessary for rapid repetitive action potentials in nociceptors, and for
spontaneous activity of damaged neurons. (Choi, J.S. and S.G. Waxman, Physiological
interactions between NaVl .7 and NaVl .8 sodium channels: a computer simulation study. J
hysiol. 106(6): p. 3173-84; Renganathan, M., T.R. s, and S.G. Waxman,

Neurophysiol., 2001. 86(2): p. 629-40; Roza, C., et al., The tetrodotoxin-resistant Na+ channel
NaVl .8 is essential for the expression of spontaneous actiVity in damaged sensory axons of mice. J
Physiol., 2003. 550(Pt 3): p. 921-6). In rized or damaged DRG neurons, NaV1.8 appears to
be the primary driver of hyper-excitablility (Rush, A.M., et al., A single sodium channel on
produces hyper- or citability in ent types of neurons. Proc Natl Acad Sci USA, 2006.
103(21): p. 8245-50). In some animal pain models, NaV1.8 mRNA expression levels have been
shown to increase in the DRG (Sun, W., et al., Reduced conduction failure of the main axon of
polymodal nociceptive C-fibres contributes to painful diabetic neuropathy in rats. Brain. 135(Pt 2):
p. 359-75; Strickland, I.T., et al., Changes in the expression ofNaVl .7, NaVl.8 and NaVl .9 in a
distinct population of dorsal root ganglia innervating the rat knee joint in a model of chronic
inflammatory joint pain. Eur J Pain, 2008. 12(5): p. 564-72; Qiu, F., et al., sed sion of
tetrodotoxin-resistant sodium ls NaVl .8 and NaVl .9 within dorsal root ganglia in a rat
model of bone cancer pain. Neurosci. Lett. 512(2): p. 61-6).
The primary drawback to the known NaV inhibitors is their poor eutic
window, and this is likely a consequence of their lack of isoform selectivity. Since NaV1.8 is
primarily restricted to the neurons that sense pain, selective NaV1.8 blockers are unlikely to induce
the adverse events common to non-selective NaV blockers. Accordingly, there remains a need to
develop additional NaV channel antagonists preferably those that are more Nav1.8 selective, more
potent and with fewer side s.

stration ofPharmaceutically acceptable salts and compositions
In certain embodiments of the invention an “effective ” of the
compound, a pharmaceutically acceptable salt thereof or pharmaceutically acceptable composition is
that amount effective for treating or lessening the severity of one or more of chronic pain, gut pain,
neuropathic pain, musculoskeletal pain, acute pain, atory pain, cancer pain, idiopathic pain,
multiple sclerosis, Charcot—Marie-Tooth me, incontinence or cardiac hmia.
The compounds and compositions, according to the method of the invention,
may be administered using any amount and any route of stration effective for treating or
lessening the severity of one or more of the pain or non-pain diseases recited herein. The exact amount
required will vary from subject to subject, depending on the species, age, and general condition of the
subject, the severity of the infection, the particular agent, its mode of administration, and the like. The
compounds of the invention are preferably formulated in dosage unit form for ease of administration
and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically
discrete unit of agent appropriate for the subject to be treated. It will be understood, however, that the
total daily usage of the compounds and compositions of the ion will be decided by the attending
physician within the scope of sound medical judgment. The specific effective dose level for any
particular subject or organism will depend upon a variety of factors including the disorder being
treated and the severity of the disorder; the activity of the c compound employed; the specific
composition employed; the age, body weight, general health, sex and diet of the subject; the time of
administration, route of administration, and rate of excretion of the specific compound employed; the
duration of the treatment; drugs used in combination or coincidental with the specific compound
employed, and like factors well known in the medical arts. The term “subject” or “patient,” as used
herein, means an animal, preferably a mammal, and most preferably a human.
The pharmaceutically acceptable compositions of this invention can be
administered to humans and other s orally, rectally, parenterally, intracistemally, intravaginally,
intraperitoneally, topically (as by powders, nts, or drops), bucally, as an oral or nasal spray, or
the like, depending on the severity of the ion being treated. In certain embodiments, the
nds of the invention may be administered orally or parenterally at dosage levels of about 0.01
mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body
weight per day, one or more times a day, to obtain the desired therapeutic effect.
Liquid dosage forms for oral administration include, but are not limited to,
pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In
addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used
in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as
ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl l, benzyl benzoate,
propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, seed, groundnut,
corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols
and fatty acid esters of sorbitan, and mixtures thereof Besides inert diluents, the oral compositions
can also include adjuvants such as wetting agents, fying and suspending agents, sweetening,
flavoring, and perfuming agents.
Injectable preparations, for example, sterile injectable s or nous
suspensions may be formulated according to the known art using suitable sing or g agents
and suspending . The sterile inj ectable preparation may also be a sterile injectable on,
suspension or emulsion in a ic parenterally acceptable diluent or solvent, for example, as a
on in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are
water, ’s solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils
WO 20820
are conventionally employed as a t or suspending medium. For this purpose any bland fixed oil
can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid
are used in the preparation of injectables.
The inj ectable formulations can be sterilized, for example, by filtration
through a bacterial-retaining filter, or by incorporating izing agents in the form of sterile solid
compositions which can be dissolved or dispersed in sterile water or other sterile able medium
prior to use.
In order to prolong the effect of a compound of the ion, it is often
desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This
may be lished by the use of a liquid suspension of crystalline or amorphous material with poor
water solubility. The rate of tion of the compound then depends upon its rate of dissolution that,
in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a
parenterally stered compound form is accomplished by dissolving or suspending the compound
in an oil vehicle. able depot forms are made by forming microencapsule matrices of the
compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of
compound to polymer and the nature of the particular polymer employed, the rate of compound release
can be controlled. Examples of other radable polymers include poly(orthoesters) and
poly(anhydrides). Depot inj ectable formulations are also prepared by entrapping the compound in
liposomes or mulsions that are compatible with body tissues.
Compositions for rectal or vaginal administration are preferably suppositories
which can be prepared by mixing the compounds of this invention with suitable non-irritating
excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at
ambient temperature but liquid at body temperature and ore melt in the rectum or vaginal cavity
and e the active compound.

compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol earate, h)
absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium. te,
magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the
case of capsules, tablets and pills, the dosage form may also comprise buffering .l
Solid compositions ofa similar type may also be employed as fillers in sofi
and hard-filled n capsules using-such excipients as lactose or milk sugar as‘well as high

ASSAYS FOR DETECTING AND MEASURING NaKINHIBITIONPROPERTIES OF COMPOUNDS
E-VIPR l membrane potential assay method with electrical stimulation
Sodium channels are voltage-dependent proteins that can be activated by
inducing membrane voltage changes by applying electric fields. The electrical stimulation instrument
and methods of use are described in Ion Channel Assay Methods PCT/US01/21652, herein
incorporated by reference and are referred to as . The instrument comprises a microtiter plate
r, an optical system for exciting the coumarin dye while simultaneously recording the coumarin
and oxonol emissions, a waveform generator, a current- or e-controlled amplifier, and a device
for inserting electrodes in well. Under integrated computer control, this instrument passes user-
programmed electrical stimulus protocols to cells within the wells of the microtiter plate.
24 hours before the assay on E-VIPR, HEK cells expressing human Nav1.8
were seeded in 384-well poly-lysine coated plates at 15,000-20,000 cells per well. HEK cells were
grown in media (exact composition is specific to each cell type and NaV e) supplemented with
% FBS (Fetal Bovine Serum, qualified; GibcoBRL #16140-071) and 1% Pen-Strep (Penicillin-
Streptomycin; GibcoBRL #15140-122). Cells were grown in vented cap flasks, in 90% ty and
% C02.

4.5mM (0.335g/L), Sodium Chloride 160mM (9.35g/L).
Hexyl Dye Solution: Bathl Buffer + 0.5% B-cyclodextrin (make this prior to
use, Sigma #C4767), 8 uM CC2-DMPE + 2.5 uM DiSBAC6(3). To make the solution added volume
of 10% Pluronic F127 stock equal to volumes of CC2-DMPE + DiSBAC6(3). The order of preparation
was first mix Pluronic and CC2-DMPE, then added 6(3) while vortexing, then added Bathl +
odextrin.
Assay Protocol:
1) otted compounds (in neat DMSO) into compound plates. Vehicle
control (neat DMSO), the ve control (20mM DMSO stock tetracaine, 125 uM final in assay) and
test compounds were added to each well at 160x desired final concentration in neat DMSO. Final
compound plate volume was 80 uL (80-fold intermediate dilution from 1 [LL DMSO spot; 160-fold
final dilution after transfer to cell plate). Final DMSO concentration for all wells in assay was 0.625%.
2) Prepared Hexyl Dye Solution.
3) Prepared cell plates. On the day of the assay, medium was aspirated and
cells were washed three times with 100 uL of Bath] Solution, maintaining 25 [LL residual volume in
each well.
4) Dispensed 25 uL per well of Hexyl Dye Solution into cell .
ted for 20-35 minutes at room temp or ambient conditions.
5) Dispensed 8O uL per well of Bathl into compound plates. Acid Yellow-17
(1 mM) was added and Potassium Chloride was altered from 4.5 to 20 mM depending on the NaV
subtype and assay sensitivity.
6) Washed cell plates three times with 100 uL per well of Bath], g 25
uL of residual volume. Then transfered 25uL per well from Compound Plates to Cell Plates.
lncubated for 20-35 minutes at room temp/ambient condition.
7) Read Plate on E-VIPR. Used the t-controlled amplifier to deliver
ation wave pulses for 10 seconds and a scan rate of 200Hz. A pre-stimulus recording was
med for 0.5 seconds to obtain the un-stimulated intensities baseline. The stimulatory waveform
was followed by 0.5 seconds of post-stimulation recording to examine the relaxation to the resting
state.
Data Analysis
Data was analyzed and reported as normalized ratios of emission ities
measured in the 460 nm and 580 nm channels. The response as a function of time was reported as the
ratios obtained using the following formula::
-l2l-
(intensity 460 nm - background 460 nm)
R(t) = ---------------------------------------------
(intensity 580 nm - background 580 nm)
The data was further reduced by calculating the l (R) and final (Rf)
ratios. These were the average ratio values during part or all of the pre-stimulation period, and during
sample points during the stimulation period. The response to the stimulus R= Rf/Ri was then calculated
and reported as a function of time.
Control responses were obtained by performing assays in the presence of a
compound with the desired properties ive control), such as tetracaine, and in the absence of
cological agents (negative control). Responses to the negative (N) and ve (P) ls
were calculated as above. The compound antagonist activity A is defined as:
A _R—P *100.
N — P where R is the ratio response of the test compound
ELECTROPHYSIOLOGYASSAYSFOR NaZACTIVITYAND INHIBITION OF TEST
COMPOUNDS
Patch clamp electrophysiology was used to assess the efficacy and selectivity
of sodium channel blockers in dorsal root ganglion neurons. Rat neurons were isolated from the dorsal
root ganglions and maintained in e for 2 to 10 days in the presence ofNGF (50 ng/ml) re
media consisted obasalA supplemented with B27, glutamine and antibiotics). Small diameter
neurons (nociceptors, 8- 12 pm in diameter) were visually fied and probed with fine tip glass
electrodes connected to an amplifier (Axon Instruments). The “voltage clamp” mode was used to
assess the compound’s IC50 holding the cells at — 60 mV. In addition, the “current clamp” mode was
employed to test the efficacy of the compounds in blocking action potential generation in response to
current injections. The s of these experiments contributed to the definition of the efficacy profile
of the compounds.
The exemplified compounds in Table 1 herein are active against Navl.8
sodium channels as measured using the assays bed herein and as presented in Table 3 below.

] IonWorks assays. This assay was performed to determine the activity for the
compounds of the present invention against non NaV1.8 channels. Sodium currents were recorded
using the automated patch clamp system, IonWorks (Molecular Devices Corporation, Inc.). Cells
expressing NaV subtypes were harvested from tissue culture and placed in suspension at 0.5-4 million
cells per mL Bath]. The IonWorks ment measured changes in sodium currents in response to
applied voltage clamp similarly to the ional patch clamp assay, except in a 384-well format.
Using the IonWorks, dose-response relationships were determined in voltage clamp mode by
depolarizing the cell from the experiment specif1c holding potential to a test potential of about 0 mV
before and following addition of the test compound. The influence of the compound on currents were
measured at the test potential.
Many cations and variations of the embodiments described herein may
be made without departing from the scope, as is apparent to those skilled in the art. The specific
