The present invention relates to a compound having sodium ion channel blocking activity, a process for preparing the same and use thereof.
Voltage-gated sodium (Nav) channels are found in all excitable cells, including muscle and nerve cells of the central and peripheral nervous systems. The sodium channels are essential for the initiation and propagation of electrical signals in the nervous system. Therefore, proper function of the sodium channels is essential to the normal function of the nerves. Ultimately, abnormal Nav channels play an important role in various diseases such as epilepsy, arrhythmia, myotonia, ataxia, multiple sclerosis, irritable bowel syndrome, urinary incontinence, visceral pain, depression, and pains. Currently, ten types of Nav channels are found in Human (Nav 1.1-1.9, Nax). Among them, four channels of Nav1.3, Nav1.7, Nav1.8 and Nav 1.9 are known to have a close connection with pain signaling, and thus are recognized as an important analgesic drug target.
A total of 10 types of Nav channels are found so far as summarized in Table 1 below. Among the 10 types, 9 types of Nav 1.1 to Nav1.9 form channels, among which NG 1.3, Nav 1.6, Nav 1.7, Nav 1.8 and Nav 1.9 are expressed in DRG.
In particular, Nav1.7 is known to be preferentially expressed in dorsal root ganglia (DRG) and sympathetic ganglia. In the sensory ganglia DRG, Nav1.7 channel is expressed in A- or C-fiber neurons, but frequently distributed in small neurons having a deep connection with pain. In particular, 85% of DRG are present in cells defined as nociceptors. This fact indicates that Nav1.7 has a close connection with pain.
The fact that Nav1.7 channel has a close connection with pain is well demonstrated in the results of not only animal studies but also human disease studies. The results of animal studies indicated that, when inflammation occurs, the gene transcript of Nav1.7 significantly increases and the expression of proteins also increases. This increase in transcript is believed to be attributable to an increase in NGF. The increased expression of Nav1.7 is believed to be the direct cause of an increase in excitability of sensory cells. In particular, when the gene of the Nav1.7 channel is removed or reduced, inflammatory pain is greatly reduced. However, animal studies do not indicate that the removal or reduction of the Nav1.7 channel gene reduces neuropathic pain. However, there are many evidences that Nav1.7 is involved in neuropathic pain in humans.
Survey results for lineages that feel severe pain or no pain give many answers to pain studies. Particularly, these results directly indicate the importance of Nav1.7 in causing pain. There are two types of inherited diseases that cause severe pain. In the case of erythromelalgia or erythermalgia among these diseases, severe pain is sometimes felt for a few hours when the body is slightly warm or takes exercises. In some cases, the skin becomes red, and the hand, the foot or the face swell. The results of genetic research indicated that SCN9A (the human gene name of Nav1.7) is present at chromosomal sites associated with diseases. Nine mutations of Nav1.7 were found until now. These mutations lower activation threshold or result in slow deactivation of the channel. Thus, these mutations can easily generate action potential even upon depolarization of some neurons (see Dib-Hajj, S D. et al., Trends in Neurosci., 30, 555-563:(2007)).
In the case of paroxysmal extreme pain disorder (PEPD) that is another inherited disease, pain is felt through life and caused when the bowels are evacuated or the anal region is stimulated. In addition to pain, the leg becomes red. As is known in the art, in PEPD, eight mutations occur in Nav1.7. These mutations occur mainly in sites that cause inactivation. The Nav channel has an inactivation ball in the linker between domains III and IV, and a peptide receiving region in the linker between the S5 and S6 segments of domains III and IV. Interestingly, mutations that cause PEPD all occur in these two regions. It appears that these cause a problem in the inactivation of Nav1.7. As expected, these mutations cause a problem in the inactivation of Nav1.7, resulting in slow deactivation of the channel (see Fertleman, C. R. et al., Neuron, 52, 767-774 (2006)). Thus, the amount of electric current that enters through the channel increases.
Still another inherited disease is congenital indifference to pain (CIP). This disease results from mutation of the Nav1.7 channel and exist in Pakistani and Chinese lineages. Persons suffering from this disease feel no pain (see Cox, J. J. et al., Nature, 444, 894-898 (2006)). CIP causes the loss of function of the Nav1.7 channel. Particularly, a mutation in this channel inhibits the expression of this channel. Thus, this channel is not expressed (see Cox, J. J. et al., Nature, 444, 894-898 (2006)). Interestingly, the knock-out of Nav1.7 does not influence other sensations. However, it influences the olfactory sensation. This fact directly indicates that Nav1.7 does not overlap with other channels in pain transmission and the function thereof is not compensated for by other Nav channels.
As described above for the above diseases, when a mutation in the Nav1.7 channel causes a gain of function, severe pain is felt, and when it causes a loss of function, pain is relieved. This is a good clinical example that directly shows that the Nav1.7 channel is the major cause of pain. Thus, it is considered that an antagonist that inhibits this channel will naturally result in a pain-relieving effect.
However, if the Nav1.7 channel antagonist inhibits a plurality of Nav channels including the Nav1.7 channel, it can show adverse effects of various CNS disturbances, such as blurring of vision, dizziness, vomiting and depression. Particularly, if it inhibits the Nav1.5 channel, it can cause cardiac arrhythmia and heart failure, which threaten life. For these reasons, selective inhibition of the Nav1.7 channels is very important.
Pains can be largely classified into three: acute pain, inflammatory pain, and neuropathic pain. Acute pain plays an important protective function of maintaining the safety of organisms from stimuli that can cause tissue injury. Thus, it is generally temporary and intense. On the other hand, inflammatory pain can be longer lasting, and the intensity thereof further increases. Inflammatory pain is mediated by various substances that are released during inflammation, including substance P, histamine, acids, prostaglandin, bradykinin, CGRP, cytokines, ATP and other substances. The third pain is neuropathic and involves nerve injury or a nerve injury caused by viral infection. It causes reconstitution of circuits with neuron proteins to cause pathological “sensitization”, which can result in chronic pain that is lasting for several years. This type of pain does not provide an advantage of adaptability and is difficult to treat by current therapy.
Particularly, neuropathic pain and intractable pain are great medical problems that have not been solved. Several hundred million patients are suffering from severe pain that is not well inhibited by current therapeutic methods. Drugs that are currently used for the treatment of pain include NSAIDS, COX-2 inhibitors, opioids, tricyclic antidepressants and anticonvulsants. Neuropathic pain is particularly difficult to treat, because it does not well respond to opioids until a high dose is reached. Currently, gabapentin is most widely used as a therapeutic agent against neuropathic pain, but it is effective for 60% of the patients and is not greatly effective. This drug is generally safe, but is problematic in terms of sedative action at high doses.
Accordingly, studies on the discovery of new regulators of the Nav1.7 channel and the use thereof for the treatment of acute pain, chronic acute, inflammatory pain and neuropathic pain have been actively conducted by global pharmaceutical companies, including Merck, AstraZeneca and the like (see US2010-0197655; US2012-0010183; WO2013-086229; WO2013-177224; US2012-0238579; WO2007-145922).
In view of the above, as a result of studying novel compounds, the present inventors has found that a compound having a chemical structure different from sodium channel blockers reported so far not only has excellent sodium channel blocking effects, thereby completing the present invention. The compounds belonging to the present invention mainly have sodium channel inhibitory activity on their own, but do not exclude a possibility of exhibiting a pharmacological action as an efficacious agent by a special body environment or by products of metabolic process, after absorption into the body.

Intermediate tert-butyl (1-(2-((4-(N-(tert-butoxycarbonyl)-N-(thiazole-4-yl)sulfamoyl)phenyl)amino)-5-fluorophenyl)pyrrolidin-3-yl)(methyl)carbamate was prepared in the same manner as described in the steps 1 to 4 of Example 1, except that 4-bromobenzenesulfonyl chloride was used instead of 4-bromo-5-chloro-2-fluorobenzenesulfonyl chloride in the step 3 of Example 1.
To the obtained intermediate was added 1.25 M HCl in MeOH (15 mL). After stirring the mixture overnight while heating to 40 to 50° C., the completion of the reaction was confirmed by TLC. The product was concentrated, and the obtained residue was separated and purified by PLC to obtain 0.05 g of the target compound (yield: 48%).

2,4-difluoro-1-nitrobenzene (i, 2.0 g, 12.6 mmol) and tert-butylmethyl(2-(methylamino)ethyl)carbamate (ii, 2.4 g, 1.0 eq.) were dissolved in DMF (20 mL), and then K2CO3 (2.6 g, 1.5 eq.) was added thereto. While maintaining the internal temperature at 60 to 70° C., the reaction mixture was stirred for 2 hours. When the reaction solution became dark yellow, the completion of the reaction was confirmed by TLC. After cooling to room temperature, EA/H20 was added and stirred, and then the layers were separated. MgSO4 was added to the separated organic layer, which was stirred, filtered and then dried. The filtrate was concentrated under reduced pressure, and the residue was dissolved in MeOH (0.13 g, 0.1 eq.) and then Pd/C (0.13 g, 0.1 eq.) was added. The inside was replaced with hydrogen gas, and the reaction mixture was stirred at room temperature for 6 hours.

In order to measure the activities of the inventive compounds as antagonists, an experiment of blocking effect against sodium ion channel 1.7 (Nav1.7) and sodium ion channel 1.5 (Nav1.5) was carried out as follows.
1) Cell Culture
The hNav 1.7 HEK 293 cell line was a cell line in which a human sodium ion channel 1.7 gene (type IX voltage-gated sodium channel alpha subunit) was stably expressed in human embryonic kidney (HEK) 293 cells, and was purchased from Millipore. The culture medium used was prepared by adding 1% 100× NEAA and 10% heat-inactivated FBS to DMEM F-12, and then adding 1% P/S as an antibiotic thereto. G-418 as a restriction enzyme was added during subculture. The hNav1.7 HEK293 cells were cultured at a confluence of about 80% in a 5% CO2 incubator at 37° C. in a T75 flask for 2 or 3 days, and detached from the flask by treatment with 0.05% trypsin solution. Then, the cells were collected by centrifugation and used in the experiment.
The hNav 1.5 HEK 293 cell line was a cell line in which a human sodium ion channel 1.5 gene (Homo sapiens sodium channel, voltage-gated, type V, alpha subunit (SCN 5 A)) was stably expressed in human embryonic kidney (HEK) 293 cells, and was purchased from Creacell. The culture medium used was prepared by mixing 2% 100× L-glutamine and 10% heat-inactivated FBS to DMEM, and then adding 1% P/S as an antibiotic thereto. G-418 as a restriction enzyme was added during subculture, and the hNav1.5 HEK293 cells were cultured at a confluence of about 80% in a 5% CO2 incubator at 37° C. in a T75 flask for 2 or 3 days, and detached from the flask by treatment with 0.05% trypsin solution. Then, the cells were collected by centrifugation and used in the experiment.
2) Preparation of Compound Samples
The compounds prepared in the Examples of the present invention were dissolved in dimethyl sulfoxide (DMSO) and used in the experiment. 90 mM and 10 mM DMSO stock solutions were prepared from each of the compounds and diluted in an extracellular solution (4 mM KCl, 138 mM NaCl, 1 mM MgCl2, 1.8 mM CaCl2, 5.6 mM Glucose, 10 mM HEPES, pH 7.45) at various concentrations, so that the final concentration of DMSO was 0.3% or less.
3) Measurement of Sodium Ion Channel Blocking Effects
In order to measure the sodium ion channel blocking effect, an IonFlux16 Auto patch clamp system (Fluxion, Inc.) and a plate for exclusive use were used. The cells were distributed in an extracellular solution (4 mM KCl, 138 mM NaCl, 1 mM MgCl2, 1.8 mM CaCl2, 5.6 mM glucose, 10 mM HEPES, pH 7.45), and then dispensed in the specified region of the plate, and each of the prepared compound samples was diluted at various concentrations, and then dispensed in the specified region of the plate. After the dispensation of the cells, the compound samples and an intracellular solution (100 mM CsF, 45 mM CsCl, 5 mM NaCl, 5 mM EGTA, 10 mM HEPES, pH 7.2) in the plate has been completed, the plate was mounted in the patch clamp system, and whether the compounds inhibited the ion channel was measured according to a set program.
Specifically, eight concentrations per compound were set, and percent inhibition was determined by calculating the percentage of inhibition of the peak current, generated after treating the cells with each concentration of the compound for 50 seconds, relative to the peak current generated before treatment with the compound, and the IC50 value was calculated using the Sigma plot program. The results of the calculation are shown in Tables 2 to 5 below.
