Abstract

A phenyl carbamate compound, and a method of treating and/or preventing multiple sclerosis comprising administering a pharmaceutically effective amount of the phenyl carbamate compound to a subject in need of treating and/or preventing multiple sclerosis, are provided.

Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • This application claims priority to and the benefit of U.S. Provisional Application No. 61/580,409, filed in the United States Patent and Trademark Office on Dec. 27, 2011, the entire contents of which are incorporated herein by reference.
    • TECHNICAL FIELD
  • The present invention provides a pharmaceutical composition for treating and/or preventing multiple sclerosis comprising a phenyl carbamate compound as an active ingredient, a use of the phenyl carbamate compound for phenyl carbamate compound, and a method of treating and/or preventing multiple sclerosis comprising administering a pharmaceutically effective amount of the phenyl carbamate compound to a subject in need of treating and/or preventing multiple sclerosis.
    • BACKGROUND ART
  • Multiple sclerosis (MS) is a chronic disease of the central nervous system (CNS), where the fatty myelin sheaths around the axons of the brain and spinal column are damaged, resulting in the inhibition of normal neurotransmission. As a result of this damage, the ability of nerve cells in the brain and spinal cord to communicate with each other is compromised. Almost any neurological symptom, including physical and cognitive disability, can appear with the disease.
  • Axonal pathology is an early feature of multiple sclerosis lesions and is initially associated with inflammation; likewise, axonal damage is a feature in experimental allergic encephalomyelitis (EAE), an autoimmune model of multiple sclerosis. During multiple sclerosis and EAE, destruction of myelin results in the redistribution and aberrant expression of axonal ion channels, and demyelinated axons are particularly sensitive to the damaging effects of free-radicals and glutamate excitotoxicity, which may additionally contribute to chronic neurodegeneration in CNS autoimmune disease.
  • There is a need for developing agents for inhibiting multiple sclerosis.
    • SUMMARY OF THE INVENTION
  • An embodiment provides an organic compound, i.e., phenyl carbamate compound. More particularly, the embodiment provides a phenyl carbamate compound of the following Chemical Formula 1, an enantiomer or a diastereomer thereof, or a mixture of enantiomers or diastereomers; or a pharmaceutically acceptable salt of organic acid or inorganic acid thereof; which has remarkably excellent treatment effect on multiple sclerosis as well as very low toxicity.

    • Biological Experimental Example I Measurement of Anti-Multiple Sclerosis Activity
  • I.1. MES (Maximal Electroshock Seizure) Test
  • In the MES test (Ref., G. Villetti et al. Neuropharmacology 40 (2001) 866-878), an electrical stimulus (mice; 50 mA, 60 Hz, 0.2 sec and rats; 150 mA 60 Hz, 0.2 sec in the test animal) supplied by 11A Shocker (IITC Life Science Company) was delivered through corneal electrodes. All mice or rats assigned to any electroshock at peak time were treated with each test compound sample which was dissolved in 30% PEG400 prepared by saline solvent applied to oral before the test. If the test animal stretching their hind limb in a straight line weren't observed in the MES test, the results indicate that the test sample had an anti-multiple sclerosis activity. Three doses of the test sample were administered orally to over 18 mice (6 mice per dose) for evaluating the respective doses at which 50% of the animals are protected from seizure (ED50). The value of ED50 (median effective dose) is calculated by Litchfield and Wicoxon log-probit method which is a dose-response relationship. Then, the test results are shown in following Table 3. Experimental animal, male ICR mice and male SD rats, were purchased from OrientBio or Nara biotech, Korea, and housed 4-5 mice per a cage for 4-5 days. The range of mice body weight was used between 19 and 26 grams and range of rats body weight was used between 100 and 130 grams.
  • I.2. Measurement of Neurotoxicity
  • The measurement of neurotoxicity of the test compounds was conducted by the method of Dunham and Miya [Dunham, N. W. and Miya, T. S. 1957. A note on a simple apparatus for detecting neurological deficit in rats and mice. J. Am. Pharm. Assoc. (Baltimore) 46: 208-209]. In the method, motor abilities of the test animals can be determined by observing whether the test animals can walk without falling from a rotator, thereby determining the value of neurotoxicity of each compound. Term “TD50” means the respective dose of the test compound at which 50% of the test animal exhibit neurotoxicity. They were pre-trained on the rotarod (Rotarod; Columbus instrument, rota-max, USA) at 6 rpm for 5 min 24 hr prior to the test. The peak time was determined by administration test material's random dose for 0.5, 1, 2, 4 hour. To evaluate the minimal neurotoxicity of the compound, the mice were placed on the Rotarod (rod circle; 3 Cm) at 6 rpm and the test animal fails to maintain walking once or more during 1 minute, it can be regarded that the test animal exhibits neurotoxicity. The ratio of TD50 to ED50 (TD50/ED50) is called as a protective index, and useful as a parameter for comparison of pharmaceutical efficacy and neurotoxicity. The obtained results are shown in following Table 3.
  • [Statistical Analysis]
  • The obtained results are shown as mean±sem. The difference between the groups was statistically analyzed by ANOVA, and then, further examined by Dunnett's test or Bonferroni test. If p is less than 0.05, it was determined that the difference between the groups had statistical significance.

    • Biological Experimental Example II The Screening Model of Muscle Relaxation Activity
  • II.1. Animal Testing Examples
  • For testing, male mice (ICR) were purchased from ORIENT BIO INC. (Korea), divided into several groups with 6 mice in each group, and were adapted for 4-5 days. The mice having the weight ranging from 19 g to 26 g were employed for the test. The pharmacological effect of the test compounds on muscle relaxation was evaluated by Rotarod test, grip strength test, and muscular force (wire hang) test. All mice were adapted to the test environment at one hour before starting the tests. The pharmacological effects of all the test compounds were evaluated by administration through peritoneal cavity of the mice (10 ul/g, bw).
  • II.2. Measurement of Muscle Relaxation Activity by Endurance Time on a Rotarod Rotating at Accelerated Speed
  • At 24 hours before testing, the mice to be tested were preliminarily trained for 5 minutes on a rod rotating at the rate of 6 revolutions per a minute. The pharmacological effect on muscle relaxation of the test compounds were evaluated by observing the mice on a rod for 5 minutes, where the rod was accelerated from 4 to 40 revolutions per a minute during the test time. The endurance time that each mouse endures on the acceleratedly rotated rod without falling off from the rod was recorded. As test time for evaluation, a maximum of 5 minutes was applied. In case the mouse does not fall off from the rod for testing time, the endurance time was recorded as 5 minutes. All the test compounds were intraperitoneally administered (10 ul/g, bw) to the mice at 15 minutes, 30 minutes, 1 hour, and 2 hours prior to the testing, and the median effective concentration (ED50) was determined at the time that the drug exhibits its maximum pharmacological effect. The obtained results were shown in following Table 7. This experimentation was conducted according to the method described in the reference, ‘Monville et al. (2006) Comparison of incremental and accelerating protocol of the rotarod test for the assessment of motor deficits in the 6-OHDA model. J. Neurosci. Meth. 158: 219-223’.
  • II.3. Measurement of muscle relaxation activity by residence time on a rotarod rotating at a fixed speed
  • All the mice to be tested were preliminarily trained for 5 minutes on a rod rotating at the rate of 15 revolutions per a minute. The mice that could not remain on the rod without falling off therefrom for a minimum of 2 minutes were excluded from this testing. After the training, all the mice were allowed to rest for 45-60 minutes. Before the administration of the test compounds, the mice were subjected to a further training for one minute on the rod rotating under the same condition, where the mice falling off from the rod were excluded from this experimentation. All the test compounds were intraperitoneally administered (10 ul/g, bw) to the mice at 15 minutes, 30 minutes, 1 hour, and 2 hours prior to the testing, and the median effective concentration (ED50) was determined at the time (generally 15 min, 30 min or 60 min) that the compounds exhibit their maximum pharmacological effect. In case a mouse stays on the rod until the test is finished, the time was recorded as 10 minutes. As test time for evaluation, a maximum of 10 minutes was applied. The obtained results were shown in following Table 7. This experimentation was conducted according to the method described in the reference, ‘Yasuda et al. (2005) Antipyretic, analgesic and muscle relaxant activities of Pueraria isoflavonoids and their metabolites from Pueraria lobata Ohwi—a traditional Chinese drug. Biol. Pharm. Bull. 28: 1224-1228’.
  • II.4. Measurement of Muscle Relaxation Activity by Grip Strength
  • A grip strength test using the test animals' forelimbs was performed using an instrument equipped with triangle ring and designed so as to easily grip with the forelimbs of experimental animals, manufactured from Ugo Basile Inc. (Ugo Basile, Model47106, Italy). The test was conducted before and after administration of the compounds to evaluate the effects thereof. All the test compounds were intraperitoneally administered (10 ul/g, bw) at 15 minutes, 30 minutes, 1 hour, and 2 hours before test, and the median effective concentration (ED50) was determined at the time (generally 15 min, 30 min or 60 min) that the compounds exhibits therir maximum pharmacological effect. The mouse was made to grip the rod with its forelimbs, and its tail was pulled, where the force at which the mouse detached from the rod was recorded. The instrument indicated the force in grams. All of the mice were given 3 opportunities for test, and the 3 highest values among the test opportunities were selected and the mean value was used as the test result. The obtained results are shown in Table 7. This experimentation was conducted according to the method described in the reference, ‘Nevins et al. (1993) Quantitative grip strength assessment as a means of evaluating muscle relaxation in mice. Psychopharmacol. 110: 92-96’.
  • II.5. Measurement of Muscle Relaxation Activity by Wire Hang
  • This experimentation was conducted using a metal wire of 30 cm in length, which was suspended between two pillars at a height of about 40 cm from the bottom covered with a soft pad. All the test compounds were administered to the mice through peritoneal cavity (10 ul/g, bw) at 15 minutes, 30 minutes, 1 hour, and 2 hours prior to the testing, and the median effective concentration (ED50) was determined at the time that the compound exhibits the maximum pharmacological effect. Each mouse was made to grip the wire using two forelimbs, and the elapse time before the mouse fell off from the wire to the pad on the bottom was recorded in seconds. Each mouse was given 5 opportunities for this test at an interval of 2 minutes period. The highest 3 records among the test opportunities were selected and the mean value was used as the test result. The obtained results are shown in Table 7. This experimentation was conducted according to the method described in the reference, ‘Jacqueline N. Crawley (1999) Behavioral phenotyping of transgenic and knockout mice: experimental design and evaluation of general health, sensory functions, motor abilities, and specific behavioral tests. Brain Res. 835: 18-26’.
  • [Statistical Analysis]
  • The obtained results are shown as mean±sem. The difference between the groups was statistically analyzed by ANOVA, and then, further examined by Dunnett's test or Bonferroni test. If p is less than 0.05, it was determined that the difference between the groups had statistical significance.

    • Biological Experimental Example III Measurement of Anti-Multiple Sclerosis Activity by MOG EAE Rat
  • III.1. Animals
  • All animal experiments were carried out according to the National Institute of Health (NIH) guidelines for the care and use of laboratory animals, and approved by the Finnish National Laboratory Animal Experiment Board. Altogether 100 female Dark Agouti rats weighing 120-170 g and purchased from Harlan Laboratories, United Kingdom were used in experiments Animals were housed at a standard temperature (22±1° C.) and in a light-controlled environment (lights on from 7 am to 8 pm) with ad libitum access to food and water.
  • EAE (experimental autoimmune encephalomyelitis) rats were induced by administration of 100 μL inoculum intradermally at the base of each tail. The inoculum consists of 20 μg of recombinant MOG (myelin Oligodendrocyte Glycoprotein)1-125 (NordicBioSite, lot#: KC1101) in PBS emulsified with incomplete Freund's adjuvant (IFA) (1:1 (v/v)) containing 200 μg of heat-inactivated Mycobacterium tuberculosis (strain H 37 RA; Difco, Detroit, Mich.).
  • Animals were grouped as follows:
      • Group A: 20 EAE rats treated p.o. twice a day with compound 1 (3 mg/kg) starting on day 0 after inoculation and continued until day 29.
      • Group B: 20 EAE rats treated p.o. twice a day with compound 1 (10 mg/kg) starting on day 0 after inoculation and continued until day 29.
      • Group C: 20 EAE rats treated p.o. twice a day with compound 1 (50 mg/kg) starting on day 0 after inoculation and continued until day 29.
      • Group D: 20 EAE rats treated p.o. twice a day with vehicle 30% PEG400 starting on day 0 after inoculation and continued until day 29.
  • All rats received compound 1 or corresponding vehicle on days 0-29. Compound 1 (at the doses of 3, 10 and 50 mg/kg, JBPOS0101) or corresponding vehicle (30% PEG400 in physiological saline solution) was administered orally (p.o: 10 ml/kg) twice a day (7-11 AM and 4-8 PM) starting at day 0 after induction of MOG EAE and continued until day 29.
  • The objective of this experimental example was to investigate whether treatment with compound 1 starting on day 0 after inoculation in MOG EAE in rats provides functional recovery during the course of disease. At the end-point, plasma, brain and spinal cord samples were collected for analytical, histological and biochemical analysis. Demyelinated area and CD68 immunoreactivity were evaluated in T-segment and C-segment of spinal cord at the end-point, day 30.
  • As the pharmaceutical efficacy duration time of a drug is longer, the administration number of the drug becomes decreased, thereby increasing the administration convenience of a patient. Such advantages may be particularly preferable for a patient suffered from a disease that requires long term administration of a drug, such as multiple sclerosis. In addition, the decrease of the administration number may be profitable in economic aspect and helpful to increase the quality of life of the patient.
  • III.2. Methods
  • Altogether 100 female Dark Agouti rats weighing 120-170 g and purchased from Harlan Laboratories, United Kingdom were used in the study. After inoculation with MOG MOG1-125 in PBS emulsified with incomplete Freund's adjuvant containing heat-inactivated Mycobacterium tuberculosis, the rats were treated with compound 1 (3 mg/kg, 10 mg/kg or 50 mg/kg, JBPOS0101) twice a day from day 0.
  • Body weight and clinical symptoms of the rats were monitored daily starting from day 0 and continued until day 30. At the end-point, brain and spinal cord samples were collected for histological and biochemical analysis. Furthermore, plasma samples were collected for sponsor's own analysis. Area of demyelinated lesions and level of inflammation in spinal cord sections were evaluated from MBP and CD68 immunostained slices with ImageJ 1.46j image analysis software (Fiji image analysis software), respectively.
  • The above method is schematically shown in FIG. 1.
  • III.2.1. End-Point Tissue and Plasma Collection
  • Rats were randomly allocated to two separate groups for sampling for histology and biochemical analysis on the basis of day 29 clinical score. Samples for histology were taken from 8 to 10 rats in each group and the rest of the rats alive were used for sampling for biochemical analysis.
  • At the end-point, day 30, 24 hours after last morning dosing all rats were deeply anesthetized with pentobarbital and blood samples were collected by cardiac puncture. Total of 800-1000 μl of blood was collected into Li-heparin microtubes, centrifuged (2000 g, 10 min, +4° C.). Two 200 μl aliquots of plasma were collected to two separate plasma collecting plasma matrix tubes, frozen on dry ice and stored at −80° C. until shipped to sponsor.
  • For histological samples, rats were transcardially perfused 10 min with cold heparinized (2.5 IU/ml) saline followed by at least 10 min perfusion with cold 4% paraformaldehyde in 0.1M phosphate buffer. The cerebellum and the rest of brains and spinal cord C and T-segments (1 cm each) were excised and post-fixed by immersion in 4% paraformaldehyde in 0.1M phosphate buffer at +4° C. for at about 24 h. The samples were then stored at +4° C. in 0.01M PBS containing 0.001% sodium azide as preservative until used for histological analysis.
  • For biochemical sampling, rats were processed the same way until saline perfusion, after which the brains and spinal cord sections were excised and dissected on ice. Brains were divided into cerebellum and left and right hemispheres. Hemispheres, cerebellum and spinal samples were weighed and put into polypropylene tubes and snap frozen in liquid nitrogen. Frozen plasma, brain and spinal cord samples were stored at −80° C. until sent to the sponsor for analytical/biochemical purposes.
  • III.2.2. Histological Analysis
  • Histological evaluation was performed on paraformaldehyde-fixed and paraffin embedded spinal cord sections at the end-point (day 30) from 10 randomly selected rats from each group. Four μm thick sections were cut at 500 lam intervals throughout C and T-segment of the spinal cord. Altogether 10 spinal cord sections from C and T-segment were stained with primary anti-MBP antibodies (Abcam, 1:400 dilution #ab40390) and appropriate secondary antibodies to assess demyelination. The surface area of demyelinated lesions (% of demyelination from total white matter/section) in the sections was evaluated.
  • In addition to demyelination analysis, one set of slides from each selected rat was used for evaluation of inflammation by using anti-CD68 (Abcam, 1:500 dilution #ab31630) and appropriate secondary antibodies (BioSite Histo for anti-MBP antibodies, KDB-10046/for anti-CD68 antibodies, KDB-10007).
  • The slices were converted to images captured at defined light and filter settings in a bright field microscope (Axio Imager M2, Zeiss) equipped with a color CCD-camera (AxioCam MRc). Sections from each selected rats were analyzed for immunostaining intensity by Fiji image analysis software (ImageJ 1.46j): MBP immunostained sections were analyzed for unstained (demyelinated) areas and CD68 immunostained sections were analyzed for stained areas (CD68 immunoreactivity). The results were expressed as demyelinated lesion or CD68 stained surface area (mm2) as % of white matter area (mm2) covered by the sectioned area.
  • III.3. Statistical Analysis
  • All values are presented as mean±standard deviation (SD) and standard error of mean (SEM), and differences were considered to be statistically significant at the P<0.05 level. Statistical analysis was performed using StatsDirect statistical software. Differences among means were analyzed by using 1-way-ANOVA followed by Dunnet's test (comparison to the vehicle group). Non-parametric data was analyzed with Kruskal-Wallis ANOVA.
  • III.4. Results
  • III.4.1. Disease Incidence and Survival
