Embodiment A

[0013] Example A: Anticonvulsant Pharmacological Experiment and Neurotoxicity Experiment

[0014] All compounds provided herein were screened for their ability to prevent and treat electrically induced epilepsy in epilepsy. Maximal electroshock MES test, used to show the efficacy of antiepileptic drugs against generalized seizures. The compounds of the invention can be used to inhibit or prevent convulsions by oral (P.O) administration to mice.

[0015] A rotarod ataxia test was also performed on mice to evaluate the neurotoxicity of each of the claimed agents, measuring TD 50 And the protection index PI. Using mice, the biological activity and neurotoxicity of the test compounds in the maximum electroshock (MES) test seizure threshold test were tested. See Krall, R.J.; Penry, J.K.; White, B.G.; Kupferberg, H.J.; Swinyard, E.A. Epilepsia. 1978, 19, 409.

Abstract

The invention relates to a compound represented by a general formula I, an addition salt thereof with a pharmaceutically acceptable acid, and an application of a medicine composition in preparing antiepileptic medicines.

Description

technical field [0001] The present invention relates to the use of 4-alkoxyphenyl-1,2,4-triazol-1-one derivatives, their addition salts with pharmaceutically acceptable acids in the preparation of antiepileptic drugs and pharmaceutical combinations containing them thing. Background technique [0002] Epilepsy is a collective term used to describe a group of chronic convulsive disorders that are characterized by transient seizures accompanied by loss or disturbance of consciousness. A variety of antiepileptic drugs are available in clinical application, such as phenobarbital, phenytoin, carbamazepine, and valproic acid. Although these drugs protect patients from various epileptic convulsions to varying degrees, their side effects and discomfort prevent their use in long-term treatment. In order to improve the therapeutic effect and eliminate or reduce side effects, new compounds with new structural features and new mechanisms of action are required. Contents of the invent...
