In addition, the present invention relates to a method for treating and/or preventing a sodium channel associated disease by administering the novel cycloalkane derivative of the present invention. 
     Description of the Related Art 
     A variety of pains including acute pain such as inflammatory pain and nociceptive pain; intractable chronic pain such as neurogenic pain, myogenic pain and fibromyalgia; and phantom limb pain probably derived from a psychogenic factor are known as pathologic pains. Since pain greatly degrades the quality of life of a patient in many cases, social loss caused by pain is incalculable. 
     Currently, nonsteroidal analgesics, nonnarcotic analgesics, narcotic analgesics, antiepileptic drugs and antidepressants are used as therapeutic agents for pain. Although a method for treating most cases of inflammatory pain and nociceptive pain has been established, there are very limited effective therapeutic agents for chronic pains such as neurogenic pain for which a nonsteroidal antiinflammatory drug is ineffective and which is resistant to narcotic analgesics. 
     Pregabalin and the like are currently used as therapeutic agents for neurogenic pain, but it is reported that pregabalin shows an effective therapeutic ratio based on self-evaluation of patients of painful diabetic neuropathy of approximately 50% (Non Patent Literature 1), and hence, it cannot be said that patient satisfaction with treatment is always attained. 
     Voltage-gated sodium channels (Navs) are ion channels each including an α subunit having four domains and auxiliary β subunits, at least nine subtypes thereof have been reported so far, and these subtypes respectively have different expression distributions and physiological actions so as to regulate biological functions. 
     The sodium channels are an essence of neural activity, and drugs such as a local anesthetic of lidocaine, an antiarrhythmic of mexiletine and an antiepileptic of carbamazepine are known as inhibitors of the sodium channels. Such drugs have, however, low selectivity for the Nav subtypes. Since sodium channels of different subtypes are expressed in muscles, cardiac muscle cells and the central nervous system as shown in Table 1, there arises a problem of an adverse drug action caused when such a drug is systemically administered.

     On the other hand, it is known that Nav 1.7 defect causes pain insensitivity in a human (Non Patent Literature 2), and since similar tendency is observed in KO mice (Non Patent Literature 3), it is regarded that a Nav 1.7 selective inhibitor is a promising target of therapeutic agents for various pains. 
     Patent Literature 1 relates to a Nav 1.7 modulator and specifically describes, for example, a compound represented by formula (A) below (in Example 811). The feature of the compound described in this patent literature is that two aromatic rings are connected through an oxygen atom, and further, N-substituted sulfonamide is connected to one of the aromatic rings (phenyl group). The compound of the present invention differs therefrom in that cycloalkane is connected to an aromatic ring through an oxygen atom. Patent Literature 1 neither describes nor suggests the structure of the compound of the present invention. 
     
       
         
         
             
             
         
       
     
     Specifically, the compound disclosed in Patent Literature 1 is described in the claim as falling within a structure represented by formula (B) below. The moiety B in this structure is defined as “phenyl or Het 2 , wherein Het 2  is defined as a 5- or 6-membered aromatic heterocyclic group containing (a) one to four nitrogen atoms, (b) one oxygen atom or one sulfur atom, or (c) one oxygen atom or one sulfur atom and one or two nitrogen atoms”. Thus, the moiety B is an aromatic substituent. The patent literature neither discloses that this moiety is a saturated substituent nor discloses that cycloalkane is formed. 
     
       
         
         
             
             
         
       
     
     Patent Literature 2 relates to an N-type calcium channel inhibitor and specifically describes, for example, a compound represented by formula (C) below (in Example 5 (11)). The compound described in this patent literature has a structure in which an aromatic ring and a saturated heterocyclic ring are connected through a polymethylene(oxy) chain. An N-substituted sulfonamide is bonded to aromatic ring (phenyl group), and two substituents are further introduced in the nitrogen atom of this sulfonamide. Specifically, the feature of this compound is that the nitrogen atom of the sulfonamide is di-substituted. The compound of the present invention differs therefrom in that: a saturated ring is not a heterocyclic ring; cycloalkane and an aromatic ring are connected through an oxygen atom and not through a polymethylene chain; and a sulfonamide moiety is mono-substituted at its nitrogen atom. Patent Literature 2 neither describes nor suggests the compound of the present invention at all.

     Test Example 1 
     Construction and Cultivation of Cell Lines 
     HNav 1.7 and hNav β1 and β2 subunits cloned from human brain were stably expressed by using Lipofectamine (Invitrogen Corp.) in HEK293A cells, and stably expressing cell lines of hNav 1.7/β1/β2-were selected by taking an amount of expression as an indicator. As the culture medium, DMEM (Invitrogen Corp.) containing 20% fetal bovine serum (Hyclone Laboratories, Inc.), 100 U/ml penicillin (Invitrogen Corp.), 100 μg/ml streptomycin (Invitrogen Corp.), 200 μg/ml hygromycin B (Invitrogen Corp.), 200 μg/ml Zeocin (Invitrogen Corp.) and 1 μg/ml puromycin (Clontech Laboratories, Inc.) was used. 
     Test Example 2 
     Electrophysiological evaluation (J. Biomol. Screen., 2006 August; 11(5): 488-96.) 
     Current record was obtained by an automated patch clamp system “IonWorks Quattro (Molecular Devices Corporation)” in Population Patch Clamp mode. The operation was conducted in accordance with the operating procedure of the system. A Dulbecco&#39;s phosphate buffer containing calcium and magnesium (Sigma) was used as an extracellular fluid, and a low C1-buffer (100 mM K-gluconate, 40 mM KCl, 3.2 mM MgCl 2 , 5 mM EGTA, 5 mM Hepes, pH 7.3) was used as an intracellular fluid. A test compound was dissolved in dimethylsulfoxide (DMSO) to prepare a 30 mM stock solution, so as to produce 4-fold serial dilutions with the extracellular fluid for attaining a DMSO concentration of 0.3% in measurement. 
     The hNav 1.7/β1/β2 cells cultured to a 70-80% confluent state in a T150 flask (Sumilon) were washed with PBS and subsequently with versene (Invitrogen Corp.), and collected by allowing to react with 0.05% trypsin (Invitrogen Corp.) at 37° C. for 3 minutes. After washing with a culture medium, the resultant cells were suspended in an extracellular fluid at a concentration of 2×10 −6  cells/ml so as to be used for the measurement. The cell membrane was perforated by using an intracellular fluid including 100 μg/ml amphotericin B (Sigma). 
     Current response was obtained at a sampling frequency of 10 kHz. Leakage current correction was performed by applying a step pulse of −110 mV before a test pulse. The membrane potential was fixed at −100 mV for 5 seconds immediately-before applying the test pulse. 
     In order to check the state-dependency of the inhibiting activity of a test compound, the test pulse was applied as follows: After applying a depolarization pulse of −10 mV for 5 msec., the potential was fixed at −100 mV for 200 msec., a potential (V1/2) at which approximately 50% of channels are inactivated was held for 2 seconds, and a depolarization pulse of −10 mV was applied for 50 msec. Such a test pulse was applied before adding the test compound and after cultivation of 5 minutes and 30 seconds with a solution of the test compound gradually added by 3.5 μl at each time. Since IonWorks Quattro has a measuring electrode head (E-head) and an agent supplying head (F-head) separated from each other, the membrane potential was not clamped during the addition and the cultivation of the test compound. 
     The inhibiting activity of the test compound was analyzed with respect to the responses to the two depolarization pulses. Data to be analyzed was selected under conditions that a ratio of a resistance value attained before adding the test compound to a resistance value attained after the addition fell in a range of 0.5 to 1.6, that a seal resistance value was 30 MΩ) or more, and that the current response obtained before adding the test compound was ⅓ or more of an average of all wells. An inhibiting activity value was determined on the basis of currents generated in response to the depolarization pulses applied before and after adding the test compound, and a 50% inhibition concentration (IC 50 ) was calculated by regression analyzing a 6-point concentration response curve in accordance with the following sigmoidal dose-response function:
 
 y =Bottom+(Top −Bottom)(1+10^[(Log EC50 −x )×Hill slope])
 
     The values of IC 50  of the inhibiting activity of test compounds corresponding to the response caused by the second depolarization pulse (with a pre-pulse potential set to V1/2) are shown in Tables 7-1 and 7-2.

     Test Example 3 
     Thermal Hyperalgesia Assay 
     In the present invention, mice and rats affected by thermal hyperalgesia were used for evaluation. 
     A test compound was orally administered to an animal, and the thermal hyperalgesia was evaluated at each measurement time determined by a study director. Specifically, thermal stimulation was applied to the sole of hind paw of the animal, and latency until it showed escape behaviors such as licking and shaking was measured. 
     The test compound was evaluated by calculating a improvement rate of pain score (%) at a constant dose against the vehicle treatment group. Improvement rates of pain score (%) at a constant dose are shown in Tables 8-1 and 8-2 as “C” when the rate was 0 to 30%, as “B” when the rate was 31 to 60%, and as “A” when the rate was 61 to 100%.
