[0082] IV. Detailed Description definition Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the subject matter described herein belongs. The definitions provided below are intended to supplement and illustrate, not preclude, definitions that would be apparent to one of ordinary skill in the art upon review of this disclosure.

[0083] Unless otherwise specified, the moieties described below are optionally substituted, i.e., they may be substituted in one or more positions. The terms substituted and substituent, whether preceded by the term "optionally" or not, as used herein, refer to the ability to replace one or more functional groups on a molecule with another functional group(s), provided that the valences of all atoms are maintained. When more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituents may be either the same or different at each position. Substituents may also be further substituted (e.g., an aryl group substituent may have another substituent, such as another aryl group, different from the aryl group, which is further substituted in one or more positions).

[0084] When the term "independently selected" is used, the substituents being referenced (e.g., R groups such as groups R1, R2, or variables such as "m" and "n") can be the same or different. For example, both R1 and R2 can be substituted alkyl, or R1 can be hydrogen and R2 can be substituted alkyl, etc.

[0085] The terms "a," "an," or "a(n)," when used herein in reference to a group of substituents, mean at least one. For example, if a compound is substituted with "an" alkyl or aryl, then the compound is optionally substituted with at least one alkyl and / or at least one aryl. Furthermore, if a moiety is substituted with R substituents, then the group can be referred to as "R-substituted." When a moiety is R-substituted, then the moiety is substituted with at least one R substituent, and each R substituent is optionally different.

[0086] A named "R" or group generally has the art-recognized structure corresponding to the group having that name, unless otherwise specified herein. For purposes of illustration, certain representative "R" groups set forth above are defined below.

[0087] The description of the compound of the present disclosure is limited by the principles of chemical bond formation known to those skilled in the art.Therefore, when group can be substituted by one or more of several substituents, this substitution is selected to be compatible with the principles of chemical bond formation, and to bring about a compound that is not inherently unstable, and / or is not known to those skilled in the art to be unstable under ambient conditions, such as aqueous conditions, neutral conditions and some known physiological conditions.For example, heterocycloalkyl or heteroaryl is bonded to the rest of the molecule through ring heteroatom according to the principles of chemical bond formation known to those skilled in the art, thereby avoiding the compound from being inherently unstable.

[0088] Unless expressly defined otherwise, a "substituent group," as used herein, includes a functional group selected from one or more of the following moieties, as defined herein:

[0089] The term hydrocarbon, as used herein, refers to any chemical group containing hydrogen and carbon. The hydrocarbon may be substituted or unsubstituted. As known to those skilled in the art, when any substitution is made, all valences must be satisfied. The hydrocarbon may be unsaturated, saturated, branched, unbranched, cyclic, polycyclic, or heterocyclic. Exemplary hydrocarbons are further defined herein below and include, for example, methyl, ethyl, n-propyl, isopropyl, cyclopropyl, ally 1, vinyl, n-butyl, tert-butyl, ethynyl, cyclohexyl, etc.

[0090] The term "alkyl," by itself or as part of another substituent, means, unless otherwise stated, a straight-chain (i.e., unbranched) or branched-chain, acyclic or cyclic saturated hydrocarbon group, or combinations thereof, and can include divalent and polyvalent groups having the specified number of carbon atoms (e.g., C1-10 means 1 to 10 carbons, including 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 carbons). In certain embodiments, the term "alkyl" refers to a C1-C20 group, inclusive, derived by removing one hydrogen atom from a hydrocarbon moiety containing between 1 and 20 carbon atoms. 1~20 refers to linear (i.e., "straight chain"), branched, or cyclic saturated hydrocarbon radicals (containing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20 carbons).

[0091] Representative saturated hydrocarbon groups include, but are not limited to, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, n-pentyl, sec-pentyl, isopentyl, neopentyl, n-hexyl, sec-hexyl, n-heptyl, n-octyl, n-decyl, n-undecyl, dodecyl, cyclohexyl, (cyclohexyl)methyl, cyclopropylmethyl, and homologs and isomers thereof.

[0092] "Branched" refers to an alkyl group in which a lower alkyl group, such as methyl, ethyl, or propyl, is attached to a linear alkyl chain. "Lower alkyl" refers to an alkyl group having 1 to about 8 carbon atoms, e.g., 1, 2, 3, 4, 5, 6, 7, or 8 carbon atoms (i.e., C 1~8 "Higher alkyl" refers to alkyl groups having about 10 to about 20 carbon atoms, e.g., 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 carbon atoms.

Still further, for alkylene and heteroalkylene linking groups, orientation of the linking group is not implied by the direction in which the formula of the linking group is written. For example, the formula -C(O)OR'- represents both -C(O)OR'- and -R'OC(O)-.

[0109] The term "spirocyclyl" refers to a polycyclic compound in which two rings have a single atom, such as carbon, as the only common member of the two rings. Thus, "spirocycloalkyl" refers to a cycloalkyl group in which the two rings have a single carbon in common, and "spiroheterocycloalkyl" or "spiroheterocycloalkyl" refers to a cycloheteroalkyl group in which the two rings have a single carbon or other atom, such as nitrogen, in common.

Substituents for each of the above-defined aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. The terms "arylene" and "heteroarylene" refer to the divalent forms of aryl and heteroaryl, respectively.

[0112] When a heteroalkyl, heterocycloalkyl, or heteroaryl contains a specific number of members (eg, "3 to 7 members"), the term "member" refers to a carbon atom or a heteroatom.

[0113] Each of the above terms is intended to include both substituted and unsubstituted forms of the indicated radical. Optional substituents are provided below.

[0114] Substituents include, but are not limited to, the following: -OR', ═O, ═NR', ═N-OR', -NR'R"-SR', -halogen, -SiR'R"R", -OC(O)R, -C(O)R, -COR-C(O)NR'R", -OC(O)NR'R", -NR"C(O)R, -NR'-C(O)NR"R"', -NR"C(O)OR', -NR-C(NR'R") ═NR''', -S(O)R, -S(O)R', -S(O)NR'R", -NRSOR', -CN, CF, fluorinated C(O) groups in a number ranging from 0 to (2m'+1) where m' is the total number of carbon atoms in such group. 1~4 R', R", R'", and R"" can each independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted alkyl, alkoxy or thioalkoxy, or arylalkyl. Other non-limiting examples of substituents include (C1-C6)alkyl, (C2-C8)alkenyl, (C3-C8)alkynyl, halogen, halo(C1-C6)alkyl, hydroxy, -O(C1-C6)alkyl, halo(C1-C6)alkoxy, (C3-C8)cycloalkyl, (C6-C 10 )aryl, heterocyclyl, heteroaryl, amino, cyano, nitro, (C1-C6)alkyl-OH, (C1-C6)alkyl-NH2, (C1-C6)alkyl-O-(C1-C6)alkyl, (C1-C6)alkyl-N-(C1-C6)alkyl, (C1-C6)alkyl(C6-C 10)aryl, —C(O)(C1-C6)alkyl, —C(O)NR′R″, —S(O)(C1-C6)alkyl, —S(O)NR′R″, —S(O)2(C1-C6)alkyl, —S(O)2NR′R″, —O(C1-C6)alkyl-S(O)(C1-C6)alkyl, —O(C1-C6)alkyl-S(O)NR′R″, —O(C1-C6)alkyl-S(O)2(C1-C6)alkyl, and —O(C1-C6)alkyl-S(O)2NR′R″. As used herein, an “alkoxy” group is an alkyl attached to the remainder of the molecule through a divalent oxygen.

[0115] When a compound of the present disclosure includes more than one R group, for example, each R group is independently selected as are R', R", R'", and R"" groups, when more than one of these groups is present. When R' and R" are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, -NR'R" is meant to include, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, those of skill in the art will understand that the term "alkyl" is meant to include groups that include carbon atoms bonded to groups other than hydrogen groups, for example, haloalkyl (e.g., -CF3 and -CH2CF3) and acyl (e.g., -C(O)CH3, -C(O)CF3, and -C(O)CHOCH3, etc.).

[0116] Two of the substituents on adjacent atoms of the aryl or heteroaryl ring can optionally form a ring of the formula -T-C(O)-(CRR')U-, where T and U are independently -NR-, -O-, -CRR'-, or a single bond, and q is an integer from 0 to 3. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring can optionally be replaced by a substituent of the formula -A-(CH)B-, where A and B are independently -CRR'-, -O-, -NR-, -S-, -S(O)-, -S(O)-, -S(O)NR'-, or a single bond, and r is an integer from 1 to 4.

[0117] One of the single bonds in the new ring thus formed may optionally be replaced by a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced by substituents of the formula -(CRR')s-X'-(C"R''')d-, where s and d are independently integers from 0 to 3, and X' is -O-, -NR'-, -S-, -S(O)-, -S(O)2-, or -S(O)2NR'-.

[0156] It will be apparent to one skilled in the art that certain compounds of the present disclosure may exist in tautomeric forms, and all such tautomeric forms of the compounds are within the scope of the present disclosure. The term "tautomer," as used herein, refers to one of two or more structural isomers that exist in equilibrium and are readily converted from one isomeric form to another.

[0157] Unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms, for example, the replacement of hydrogen by deuterium or tritium, or 13 C or 14 Compounds having this structure including the replacement of a carbon with a C-enriched carbon are within the scope of this disclosure.

[0158] The compounds of the present disclosure may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds.

All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure.

[0159] The compounds of the present disclosure can exist as salts, particularly as pharmaceutically acceptable salts. The present disclosure includes such salts. Examples of applicable salt forms include hydrochloride, hydrobromide, sulfate, methanesulfonate, nitrate, maleate, acetate, citrate, fumarate, tartrate (e.g., (+)-tartrate, (-)-tartrate, or a mixture thereof, including a racemic mixture), succinate, benzoate, and salts with amino acids such as glutamic acid. These salts can be prepared by methods known to those skilled in the art. Also included are base addition salts, such as sodium, potassium, calcium, ammonium, organic amino, or magnesium salts, or similar salts. When a compound of the present disclosure contains a relatively basic functional group, an acid addition salt can be obtained by contacting the neutral form of such a compound with a sufficient amount of the desired acid, either neat or in a suitable inert solvent, or by ion exchange. Examples of acceptable acid addition salts include those derived from inorganic acids such as hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydroiodic, or phosphoric acids, and salts derived from organic acids such as acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, and methanesulfonic acids. Also included are salts of amino acids such as alginate, and salts of organic acids such as glucuronic or galactunoric acids. Certain specific compounds of the present disclosure contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts.

[0160] The neutral forms of the compounds can be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner.

[0161] The parent form of the compound differs from the various salt forms in certain physical properties, such as solubility in polar solvents.

[0162] Certain compounds of the present disclosure can exist in non-solvated form and solvated form, including hydrated form.Generally, solvated form is equivalent to non-solvated form and is included in the scope of the present disclosure.Specific compounds of the present disclosure can exist in multiple crystalline forms or amorphous forms.Generally, all physical forms are equivalent for the use envisioned by the present disclosure and are intended to be within the scope of the present disclosure.

[0163] In addition to salt forms, the present disclosure provides compounds in prodrug form. Prodrugs of the compounds described herein are compounds that readily undergo chemical changes under physiological conditions to yield compounds of the present disclosure. Furthermore, prodrugs can be converted to compounds of the present disclosure by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to compounds of the present disclosure when placed in a transdermal patch reservoir with a suitable enzyme or chemical reagent.

[0164] The term "protecting group" refers to a chemical moiety that blocks some or all of the reactive moieties of a compound, preventing such moieties from participating in a chemical reaction until the protecting group is removed, such as those listed and described in TW Greene, PGM Wuts, Protective Groups in Organic Synthesis, 3rd ed. John Wiley & Sons (1999). When different protecting groups are used, it can be advantageous for each (different) protecting group to be removable by a different means. Protecting groups that are cleaved under completely different reaction conditions allow for differential removal of such protecting groups.

[0165] For example, protecting groups can be removed by acid, base, and hydrogenolysis. Groups such as trityl, dimethoxytrityl, acetal, and tert-butyldimethylsilyl are acid-labile and can be used to protect carboxy and hydroxy reactive moieties in the presence of amino groups protected by hydrogenolysis-removable Cbz and base-labile Fmoc groups. Carboxylic acid and hydroxy reactive moieties can be blocked with base-labile groups such as, but not limited to, methyl, ethyl, and acetyl in the presence of acid-labile groups such as tert-butyl carbamate, or amines blocked with carbamates that are both acid- and base-stable but removable by hydrolysis.

[0166] Carboxylic acid and hydroxy reactive moieties may also be blocked with hydrolytically removable protecting groups such as benzyl groups, while amine groups capable of hydrogen bonding with acids may be blocked with base labile groups such as Fmoc. Carboxylic acid reactive moieties may be blocked with oxidatively removable protecting groups such as 2,4-dimethoxybenzyl, while coexisting amino groups may be blocked with fluoride labile silyl carbamates.

[0167] Because allyl blocking groups are stable, they are useful in the presence of acid- and base-protecting groups and can be subsequently removed by metal or pi-acid catalysis. For example, an allyl-blocked carboxylic acid can be deprotected by palladium(O)-catalysis in the presence of acid-labile t-butyl carbamate or base-labile acetate amine protecting groups. Yet another form of protecting group is a resin to which a compound or intermediate can be attached. As long as the residue is attached to the resin, the functional group is blocked and cannot react. Once released from the resin, the functional group is available for reaction.

[0206] General synthetic scheme Several methods for preparing the compounds of the present invention are illustrated in the following schemes and examples. The present invention further provides a process for preparing the compounds of formula I defined above. In some cases, the order of carrying out the above-described reaction schemes can be changed to facilitate the reaction or to avoid undesired reaction products. The following examples are provided for illustrative purposes only and should not be construed as limitations on the disclosed invention.

[0207] [ka] As illustrated in Scheme A, compounds of formula (I) can generally be synthesized starting from carboxylic acid A-1 by reacting it with a substituted aniline or heteroaryl aniline A-2 using a standard amide coupling reagent, including but not limited to HATU, TBTU, EDC, or T3P, and a base such as DIEA in an organic solvent to provide an intermediate of type A-3. Intermediate A-3 can contain a protecting group (PG), such as Boc, which can be removed by treatment with an acid such as TFA to provide a compound of formula (I) having structure A-4. Any suitable PG, such as Cbz or Fmoc, can be used and removed accordingly. Alternatively, carboxylic acid A-1 can be treated with ammonia or a primary amine (R5NH2) in the presence of an amide coupling reagent, such as HATU, and a base such as DIEA to provide a carboxamide intermediate A-5, which can undergo metal-catalyzed coupling with a halogen-substituted aryl or heteroaryl compound of type A-6 to provide a compound of formula A-3. Compounds of formula (I) can then be obtained from A-3 as described.

[0208] [ka] As further illustrated in Scheme B, in general, compounds of the present invention can be prepared by reacting intermediate A-1 with amine B-1 using amide coupling conditions, or by activation of an appropriately functionalized carboxylic acid A-1 with (COCl) or POCl and an amine B-1 and a base such as DIEA or pyridine in DCM, DMF, or THF to give compounds of type B-2. Compounds of formula B-3 can be formed by removing a protecting group such as Boc under acidic conditions. In some instances, B-3 can be separated into the corresponding R and S isomers using chiral HPLC. The R and S isomers can also be prepared by coupling the acid with an enantiomerically pure amine B-1 followed by deprotection.

[0209] [ka] As illustrated in Scheme C, compounds of the present invention can generally be prepared by activating an appropriately functionalized carboxylic acid A-1 with either (COCl) or SOCl in an organic solvent, followed by the addition of NHOH to yield C-1. Intermediate C-1 can then be combined with variously substituted Br compounds C-2 using Xantphos-Pd-G2 mediated coupling conditions to yield intermediate C-3. Compounds of formula C-3 can be treated with ammonium carbonate or ammonium carbamate and (diacetoxyiodo)benzene (PIDA) in methanol to provide compounds of formula B-3. In some instances, B-3 was separated into the corresponding R and S isomers using chiral HPLC conditions. Compounds of formula B-4 were obtained using standard amide coupling reagents, such as, but not limited to, HATU, a base, such as DIEA, and C-4.

[0210] The above schemes are intended to be illustrative and not limiting in any way. One skilled in the art can prepare compounds of formula (I) using these general schemes as a guide, but other methods are available to achieve the synthesis of compounds of the invention. Specific methods to further illustrate the synthesis of compounds of formula (I) are provided with each of the examples.

Cells were cultured at 37°C / 5% CO2 in Ham's F-12 medium supplemented with 10% fetal bovine serum, 100 U / mL penicillin G sodium, 100 mg / mL streptomycin sulfate, and selection antibiotics (0.01 mg / mL blasticidin, 0.4 mg / mL zeocin, and 0.25 mg / mL hygromycin). On the day of recording, cells in the culture dish were washed twice with Hank's balanced salt solution (HBSS) and treated with Accutase for approximately 20 minutes. Immediately before use in the SynchroPatch384PE using an 8-well NPC-384 chip, cells were washed in HBSS to remove Accutase and resuspended in extracellular solution. All experiments were performed at ambient temperature. The intracellular solution contained (mM): CsCl 50; CsF 90; MgCl2 5; EGTA 1; HEPES 10, pH adjusted to 7.2 with CsOH. The extracellular solution contained (mM): NaCl 137; KCl 4.0; CaCl2 3.8; MgCl2 1; HEPES 10; glucose 10, pH adjusted to 7.4 with NaOH. 100 nM tetrodotoxin (TTX) was added to the extracellular solution to block endogenous TTX-sensitive sodium currents.

[0307] Compounds were tested in quadruplicate in 0.3% DMSO and 0.03% pluronic acid. Compounds were diluted 1:3.33 with extracellular solution to generate eight-point concentration-response curves. Each plate included a historical positive control and up to 10 compounds. 300 μM tetracaine and 0.3% DMSO + 0.03% pluronic acid were used as high and low controls, respectively.

[0308] Whole-cell patch-clamp recordings were performed according to Nanion's standard procedure for SyncroPatch384PE®. Cells were held at a holding potential of -120 mV. A 30 ms depolarizing step to 10 mV was applied (P1 measurement), followed by a 100 ms hyperpolarizing step to -100 mV. A 10 s inactivating step at -35 mV was applied, followed by a 20 ms step to -100 mV, followed by a 30 ms step to 10 mV (P2 measurement), followed by a 30 ms return to -100 mV. The sweep interval was 15 s. After establishing the whole-cell configuration in the extracellular solution, cells were washed in an extracellular solution containing 0.3% DMSO and 0.03% pluronic acid to stabilize baseline currents. Compounds were then applied to each well using the SynchroPatch384 PE system, and currents were recorded in the extracellular solution for 5 minutes, after which tetracaine was applied at the end of the experiment to achieve complete blockade. Compound efficacy was assessed using two readings: resting-state block (P1 measurement) or inactivation-state block (P2 measurement), to obtain IC50 values. Values ​​were normalized to high (tetracaine) and low (DMSO + pluronic acid) controls.

Cells were cultured at 37°C / 5% CO2 in DMEM / F-12 supplemented with 10% fetal bovine serum, 1x non-essential amino acids, and selection antibiotics (0.625 μg / mL puromycin, 400 μg / mL geneticin, and 100 μg / mL hygromycin). One or two days before recording, cells were transferred to a cooler incubator at 30°C / 5% CO2 to increase channel surface expression. On the day of recording, cells in the culture dish were incubated with Ca 2+ -Mg 2+Cells were washed twice with free DPBS and treated with Detachin (Genlantis, San Diego) for 3 minutes, then resuspended in serum-free medium (EX-CELL® ACF CHO medium (Sigma-Aldrich) for cell culture supplemented with 0.04 mg / mL soybean trypsin inhibitor and 25 mM HEPES (all components supplied by Sigma-Aldrich, St. Louis, MO)) and allowed to recover for a minimum of 20 minutes in an on-board QStirrer. All experiments were performed at ambient temperature. The intracellular solution contained (mM): CsCl, 50; CsF, 90; MgCl2, 2; EGTA, 5; HEPES, 10, and the pH was adjusted to 7.2 with CsOH. The extracellular solution contained (mM): NaCl, 137; KCl, 4; CaCl, 3.8; MgCl, 1; HEPES, 10; glucose, 10, and the pH was adjusted to 7.4 with NaOH. 500 nM tetrodotoxin (TTX) was added to this extracellular solution to block endogenous TTX-sensitive sodium currents.

[0311] Compounds were tested in two cohorts of wells in an interleaved fashion to generate a total of eight concentration-response curves. The final concentration contained 0.1% DMSO and 0.03% pluronic acid. The concentration range generally ranged from 0.01 to 300 nM. Compounds were diluted 1:10 with extracellular solution within each cohort. DMSO (0.1% by volume) served as a vehicle control to verify assay performance.

[0312] Whole-cell patch-clamp recordings were performed according to Sophion standard procedures on a QPatch II®. Cells were held at a holding potential of -120 mV. A 30 ms depolarizing step to 10 mV was applied to measure inward Na +Currents were elicited. The interval between sweeps was 15 seconds. After establishing the whole-cell configuration in the extracellular solution, cells were washed twice in an extracellular solution containing 0.1% DMSO and 0.03% pluronic acid to stabilize the baseline current. Compounds were then applied to each well in an ascending fashion within a cohort using the QPatch II system, and currents were recorded for 5 minutes for each concentration. The percentage of remaining current was determined by averaging at least five sweeps within each concentration and normalizing to the most recent pre-compound saline period. Compound potency (IC 50 ) values ​​were assessed for resting-state block only. Wells in which the initial sodium current magnitude was less than 2 nA or the whole-cell resistance fell below 100 MΩ were excluded from analysis.

[0313] The table below shows the human Na V 1.8, and "A" indicates the potency of the compound against IC 50 "B" indicates an IC of greater than 5 nM but less than 50 nM or equal to 50 nM. 50 "C" represents an IC greater than 50 nM but less than 100 nM or equal to 100 nM 50 "D" represents an IC of greater than 100 nM but less than 200 nM or equal to 200 nM 50 "E" represents an IC greater than 200 nM 50 Represents.

[0346] General synthetic scheme Several methods for preparing the compounds of the present invention are illustrated in the following schemes and examples. The present invention further provides a process for preparing the compounds of formula I defined above. In some cases, the order of carrying out the above-described reaction schemes can be changed to facilitate the reaction or to avoid undesired reaction products. The following examples are provided for illustrative purposes only and should not be construed as limitations on the disclosed invention.

[0347] [ka] As illustrated in Scheme A, compounds of formula (I) can generally be synthesized by starting with carboxylic acid A-1 and reacting it with a substituted aniline or heteroaryl aniline A-2 using a standard amide coupling reagent, including but not limited to HATU, TBTU, EDC, or T3P, and a base such as DIEA in an organic solvent to provide an intermediate of type A-3. Intermediate A-3 can contain a protecting group (PG), such as Boc, which can be removed by treatment with an acid such as TFA to provide an intermediate having structure A-4. Any suitable PG, such as Cbz or Fmoc, can be used and removed accordingly. The NH group of A-4 can be acylated using a standard amide coupling reagent, such as HATU, in combination with a carboxylic acid and a base such as DIEA, or the NH group can be acylated with a reactive carboxylic acid ester, such as an N-hydroxysuccinimide ester, to provide a compound of formula (I) after removal of the protecting group, if present. Numerous methods exist for acylating the NH group, which can be performed by one skilled in the art. If desired, the compound of formula (I) can be further modified to obtain additional compounds of formula (I). Alternatively, the carboxylic acid A-1 can be treated with ammonia or a primary amine (R5NH2) in the presence of an amide coupling reagent such as HATU and a base such as DIEA to give the carboxamide intermediate A-5, which can undergo metal-catalyzed coupling with a halogen-substituted aryl or heteroaryl compound of the type A-6 to give a compound of formula A-3. The compound of formula (I) can then be obtained from A-3 as described.

[0348] [ka] As further illustrated in Scheme B, in general, compounds of the present invention can be prepared by reacting intermediate A-1 with amine B-1 using amide coupling conditions, or by activation of an appropriately functionalized carboxylic acid A-1 with (COCl) or POCl and an amine B-1 and a base such as DIEA or pyridine in DCM, DMF, or THF to give compounds of type B-2. Compounds of formula B-3 can be formed by removing a protecting group such as Boc under acidic conditions. In some instances, B-3 can be separated into the corresponding R and S isomers using chiral HPLC. The R- and S-isomers can also be prepared by coupling the acid with enantiomerically pure amine B-1 followed by deprotection. The sulfoximine nitrogen of intermediate B-3 is acylated using a standard amide coupling reagent, such as, but not limited to, HATU, a base such as DIEA, and HO2C-R6-PG to give compounds of formula B-4. As shown, if B-4 contains PG, it can be removed to give a compound of formula B-5. For example, if a Boc group was used to protect the sulfoximine, it can be removed by treatment with TFA to give a compound of formula B-5. A trialkylsilyl group can be used to protect the hydroxyl group and can be removed by treatment with an aqueous acid such as acetic acid. If no protecting group is required, B-3 can directly give compound B-5.

[0349] [ka] As illustrated in Scheme C, compounds of the present invention can generally be prepared by activating an appropriately functionalized carboxylic acid A-1 with either (COCl) or SOCl in an organic solvent, followed by the addition of NHOH to give C-1. Intermediate C-1 can then be combined with variously substituted Br compounds C-2 using Xantphos-Pd-G2-mediated coupling conditions to give intermediate C-3. Compounds of formula C-3 can be treated with ammonium carbonate or ammonium carbamate and (diacetoxyiodo)benzene (PIDA) in methanol to provide compounds of formula B-3. In some instances, B-3 was separated into the corresponding R and S isomers using chiral HPLC conditions. Compounds of formula B-4 were obtained using standard amide coupling reagents, such as, but not limited to, HATU, a base such as DIEA, and HO2C-R6-PG. When the protecting group PG was Boc, it was removed by treatment with TFA to give compounds of formula B-5. A trialkylsilyl group can be used to protect the hydroxyl group and can be removed by treatment with an aqueous acid such as acetic acid. If no protecting group is needed, B-3 can directly give compound B-5.

[0350] The above schemes are intended to be illustrative and not limiting in any way. One skilled in the art can prepare compounds of formula (I) using these general schemes as a guide, but other methods are available to achieve the synthesis of compounds of the invention. Specific methods to further illustrate the synthesis of compounds of formula (I) are provided with each of the examples.

Each plate included a historical positive control and up to 10 compounds. 300 μM tetracaine and 0.3% DMSO + 0.03% pluronic acid were used as high and low controls, respectively.

[0425] Whole-cell patch-clamp recordings were performed according to Nanion's standard procedure for SyncroPatch384PE®. Cells were held at a holding potential of -120 mV. A 30 ms depolarizing step to 10 mV was applied (P1 measurement), followed by a 100 ms hyperpolarizing step to -100 mV. A 10 s inactivating step at -35 mV was applied, followed by a 20 ms step to -100 mV, followed by a 30 ms step to 10 mV (P2 measurement), followed by a 30 ms return to -100 mV. The sweep interval was 15 s. After establishing the whole-cell configuration in the extracellular solution, cells were washed in an extracellular solution containing 0.3% DMSO and 0.03% pluronic acid to stabilize baseline currents. Compounds were then applied to each well using the SynchroPatch384 PE system, and currents were recorded in the extracellular solution for 5 minutes, after which tetracaine was applied at the end of the experiment to achieve complete blockade. Compound efficacy was assessed using two readings: resting-state block (P1 measurement) or inactivation-state block (P2 measurement), to obtain IC50 values. Values ​​were normalized to high (tetracaine) and low (DMSO + pluronic acid) controls.

[0463] General synthetic scheme Several methods for preparing the compounds of the present invention are illustrated in the following schemes and examples. The present invention further provides a process for preparing the compounds of formula I defined above. In some cases, the order of carrying out the above-described reaction schemes can be changed to facilitate the reaction or to avoid undesired reaction products. The following examples are provided for illustrative purposes only and should not be construed as limitations on the disclosed invention.

[0464] Compounds of formula (I) can be prepared from A-1 starting materials or intermediates, including but not limited to, methyl 4,6-dichloropyridazine-3-carboxylate, 2,6-dichloro-3-(trifluoromethyl)pyridine, 2,4-dichloro-5-nitropyridine, methyl 2-hydroxy-4-methylnicotinate, 2-bromo-3,5-dichloroisonicotinic acid, methyl 2,4-dichloro-6-methylpyrimidine-5-carboxylate, methyl 5-bromo-2-chloro-4-methylnicotinate, ethyl 5-bromo-3-fluoro-2-diiodoisonicotinate, 2,6-dichloro-4-methylnicotinic acid, ethyl 2-chloro-4-methyl-6-(trifluoromethyl)nicotinate, methyl 2-chloro-5-nitronicotinate, 2-chloro-4,6-dimethylnicotinic acid, which are commercially available, synthesized using published procedures, or by methods known to those skilled in the art. Modifications can be made to the starting materials and intermediates to prepare still other intermediates, having alternative or additional groups such as alkyl, fluoroalkyl, trifluoromethyl, cyano, halogen, chloro, bromo, iodo, amino, nitro, aryl, heteroaryl, carboalkoxy, alkoxy, aryloxy, and heteroaryloxy. The methods used to convert the starting materials to compounds of formula (I) are provided for each of the examples.

[0465] [ka] As illustrated in Scheme A, compounds of Formula (I) can generally be synthesized from a starting material or intermediate of type A-1. Rings A and X of A-1 can be first modified to provide intermediate A-1, suitable for subsequent modification. Modifications can include, but are not limited to, exchange of trifluoromethyl with halogen, metal-catalyzed coupling to introduce alkyl, aromatic, or heteroaromatic groups, treatment with nitric acid to introduce a nitro group, reduction of the nitro group to an amino group, or other transformations known to those skilled in the art. The X group of A-1 can be displaced with various substituted phenols or heteroaromatic alcohols in the presence of a base such as KCO, CsCO, NaH, KH, or other organic bases to provide intermediates of type A-2. Intermediates of type A-2 may or may not be further modified at ring A, and the carboxylic acid ester is then hydrolyzed with KOH or LiOH in aqueous solvent to provide carboxylic acid intermediate A-3. Intermediate A-3 can be reacted with a substituted aniline or heteroaryl aniline using standard amide coupling reagents, including but not limited to HATU, TBTU, EDC, or T3P, in an organic solvent, and a base, such as DIEA, to provide a compound of formula (I). If desired, the compound of formula (I) can be further modified to provide additional compounds of formula (I). Alternatively, intermediate A-2 can be treated with ammonia, a primary amine (R1NH2), or a dialkylaluminum amide to provide carboxamide A-4, which can undergo metal-catalyzed coupling with a halo-substituted aniline or heteroaryl aniline to provide a compound of formula (I).

[0466] [ka] As illustrated in Scheme B, compounds of the present invention can generally be prepared by reacting a substituted compound A-1 with an aryl- or heteroaryl-alcohol B using a base such as DIEA or an inorganic base such as KCO or CsCO to yield intermediate A-2. Intermediate A-2 can be converted to the corresponding acid A-3 by treating A-2 with a base such as KOH, LiOH, or NaOH in aqueous EtOH or MeOH or a mixture of MeOH / THF / HO. Intermediate A-5 can be formed either by treating A-3 and an amine C using amide coupling conditions or by activation of an appropriately functionalized carboxylic acid A-4 with (COCl) or POCl and an amine C and a base such as DIEA or pyridine in DCM, DMF, or THF. Compounds of formula A-6 can be formed by removing a protecting group such as Boc under acidic conditions. In some instances, A-6 can be separated into the corresponding R and S isomers using chiral HPLC. The R- and S-isomers can also be prepared by coupling the acid with an enantiomerically pure amine C followed by deprotection.

[0467] [ka] As illustrated in Scheme C, in general, compounds of the present invention can be prepared by activating an appropriately functionalized carboxylic acid A-3 with either (COCl) or SOCl in an organic solvent, followed by the addition of NHOH to give B-1. Intermediate B-1 can then be combined with variously substituted Br compounds using Xantphos-Pd-G2-mediated coupling conditions to give intermediate B-2. Compounds of formula B-2 can be treated with ammonium carbonate or ammonium carbamate and (diacetoxyiodo)benzene (PIDA) in methanol to give compounds of formula B-3. In some instances, B-3 was separated into the corresponding R and S isomers using chiral HPLC conditions.
