Description:
PHENYL CARBAMATE COMPOUND AND A COMPOSITION FOR PREVENTING OR TREATING A NERVE GAS-INDUCED DISEASE

COMPRISING THE SAME

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

The present invention relates to a composition for preventing or treating a nerve gas-induced disease comprising a phenyl carbamate compound and a method for preventing or treating a neurological disease therewith.

DESCRIPTION OF THE RELATED ART

Organophosphorus nerve agents are the principal chemical warfare agents known to produce brain injury. They block hydrolysis of the neurotransmitter acetylcholine by inhibiting the enzyme acetylcholinesterase, resulting in greatly increased postsynaptic acetylcholine levels. This causes a spectrum of effects, including miosis, excess secretions, nausea, vomiting, and muscle fasciculations. At moderate to high doses, nerve agents also cause seizures and associated convulsions. If left untreated, seizures rapidly progress to status epilepticus (SE) and cause irreversible seizurerelated brain damage (SRBD).

Although there is little neuropathological data from patients who have survived nerve agent attacks, abundant evidence is available from animal models, many of which involve persistent SE. The profound brain damage produced by nerve agents was first described by Petras29; Lemercier et al30; and McLeod et al. Since then, numerous studies have greatly enhanced the understanding of neuropathology resulting from nerve agent intoxication.

Neuroprotection as a Treatment for Nerve Agent Survivors. Neuroprotection refers to the relative preservation of neuronal structure and/or function. In the case of an ongoing insult (a neurodegenerative insult) the relative preservation of neuronal integrity implies a reduction in the rate of neuronal loss over time, which can be expressed as a differential equation. It is a widely explored treatment option for many central nervous system (CNS) disorders. Neuroprotection aims to prevent or slow disease progression and secondary injuries by halting or at least slowing the loss of neurons. Neuroprotective treatments often target oxidative stress and excitotoxicity. both of which are highly associated with CNS disorders. Not only can oxidative stress and excitotoxicity trigger neuron cell death but. when combined they have synergistic effects that cause even more degradation than on their own. Thus limiting excitotoxicity and oxidative stress is a very important aspect of neuroprotection.

Throughout this application, various publications and patents are referred and citations are provided in parentheses. The disclosures of these publications and patents in their entities are hereby incorporated by references into this application in order to fully describe this invention and the state of the art to which this invention pertains.

SUMMARY OF THE INVENTION

The present inventor has made intensive studies to develop a novel agent with excellent neuroprotecting activity which may be applied to effective treatment for various nerve gas-induced diseases. As results, the present inventor has discovered that the phenyl carbamate derivatives represented by above formula 1 provide highly enhanced neuroprotecting activity. Accordingly, it is an object of this invention to provide a composition for preventing or treating a nerve gas-induced disease.

It is another object of this invention to provide a method for preventing or treating a nerve gas-induced disease. Other objects and advantages of the present invention will become apparent from the following detailed description together with the appended claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 represents the measurement of benzodiazepine-resistant electrographic status epilepsy model of l-(2-chlorophenyl)-(S)-l-hydroxypropyl-(S)-2-carbamate (compound 1) in the test (Rats) by a graph summarizing the percent change in EEG power over time. Only animals that underwent pilocarpine-induced status epilepticus and had an acceptable EEG signal were included in the analysis. In addition, the vehicle group includes historical controls derived from other temporally adjacent trials. The data are the mean (solid line) and 95% confidence intervals (shaded) of model predictions for each of the treatments normalized to the power at the time of the injection of test compound/vehicle. Differences between the groups were assessed using the non-parametric Mann-Whitney U-teat. The dashed lines represent the time points at which a significant difference was found between the two groups (p<0.05).

DPPH

The free radical scavenging capacity of the extracts was determined using DPPH (Sigma, U.S.A). DPPH solution (0.2mM) was prepared in 99.8% methanol. Compounds were mixed with methanol to prepare the stock solution(30% w / w ). Freshly prepared DPPH solution was 1ml taken in test tubes and test compounds were 1ml added followd to every test tube so that the final volume 2ml and after 20 min, the absorbance was read at 517nm using a spectrophotometer (OPTIZEN, Korea). Control sample was prepared containing the same volume without test compounds. 99.8% methanol was served as blank. % radical scavenging activity (RSA) of the DPPH free radical was measured by using the following equation (Rohmam, A., Riyanto, S., Yuniarti, N., Saputra, W. R., Utami, R. and Mulatsih, W. 2010. Antioxidant activity, total phenolic, and total flavaonoid of extracts and fractions of red fruit(Pandanus conoideus Lam).

Lithium-pilocarpine model for Prevention study

Male Sprague-Dawley rats (purchased from Orient Bio Inc. Korea) of body weight 200-230g were used for these studies and housed 4-5 rats per a cage for 4-5 days. On the day prior to status epilepsy (SE), rats received 127 mg/kg lithium chloride (Sigma, St. Louis, MO, U.S.A.) intraperitoneally (i.p.). Approximately 18-20 h following this treatment, the rats were given 43 mg/kg pilocarpine (Sigma) intraperitoneally. An i.p. injection of 2 mg/kg methyl-scopolamine (Sigma) was administered 30 min prior to pilocarpine to block the effects of the muscarinic agonist on peripheral cholinergic receptors. The test drug was administered intraperitoneally (i.p.) in a volume of 2ul/g body weight. Pharmacological effects of all the test materials were evaluated to compare the test groups (n=6) with a control group (n=6). Control group was administrated vehicle, only. The peak time was determined by administration test material's random dose for 0.5, 1, 2, 4 hour. The time that the most protect was defined peak time and ED50 was determined by other dose administration at peak time. The animals were then transferred to observation cages and observed continuously for 90 min. The seizure activity was elicited in approximately 95% of control group. Protection was defined as a complete absence of seizure grade 4~5 based on Racine scale (Racine, 1972) over the 90-min observation period. The effective dose of compound necessary to protect against seizures to 50% of controls (i.e. ED50) was determined by log probit analysis using SPSS software program (SPSS Inc.). The obtained results are shown in following Table 4.

Lithium-pilocarpine induced status epilepticus (SE) model

Pilocarpine-induced SE shares similarities to nerve-agent intoxication and poisoning with other organophosphates. In the pilocarpine model, the ensuing seizures and SE are reproducible and well-characterized, whereas the seizure activity in organophosphate models is less well-defined and more variable (Todorovic MS et. al., (2012) Characterization of status epilepticus induced by two organophosphates in rats. Epilepsy Res 101:268-276.). Animal models based on organophosphate analogs also have a high mortality rate, necessitating the need for antidotal pretreatment, which can modulate responsiveness to anticonvulsant therapy (Shih TM et. al, (2007) Anticonvulsants for nerve agent-induced seizures: the influence of the therapeuticdose of atropine. J Pharmacol Exp Ther 320:154-161). Therefore, the pilocarpine model has several advantages as a screen or test system for identifying treatments for organophosphate-induced SE.

Male Sprague-Dawley rats (purchased from Orient Bio Inc. Korea) of body weight 200-230g were used for these studies and housed 4-5 rats per a cage for 4-5 days. On the day prior to SE, rats received 127 mg/kg lithium chloride (Sigma, St. Louis, MO, U.S.A.) intraperitoneally (i.p.). Approximately 18-20 h following this treatment, the rats were given 43 mg/kg pilocarpine (Sigma) intraperitoneally. An i.p. injection of 2 mg/kg methyl-scopolamine (Sigma) was administered 30 min prior to pilocarpine to block the effects of the muscarinic agonist on peripheral cholinergic receptors. The effects of the test compounds dissolved in 30% Poly Ethylene Glycol 400 (Acros Organics, Geel, Belgium) or 20% Tween80 were studied at various times or 30 in after the occurrence of the first motor seizure or SE onset. The drug was administered intraperitoneally in a volume of 2 ul/ g body weight. Pharmacological effects was evaluated to compare the test groups with a control group (n=8). Control group was administrated vehicle, only. The obtained results are shown in Table 5 and Figure 1. (Reference; Racine RJ. (1972). Modification of seizure activity by electrical stimulation: II Motor seizure. Electroenceph. Clin. Neurophysiol. 32: 281-294.)

Anti -excitation activity

In the MES test(Ref., G. Villetti et al. Neuropharmacology 40(2001) 866-878), an electrical stimulus(mice; 50mA, 60Hz, 0.2sec and rats; 150mA 60Hz, 0.2sec in the test animal) supplied by 11A Shocker(IITC Life Science Company) was delivered through corneal electrodes. All mice 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-excitation 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 6. 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. The obtained results are shown in following Table 6. 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; 3Cm) at 6rpm 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 6.

[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.
