  Syntheses and Evaluation of Anticonvulsant Profile and Teratogenicity of Novel Amide Derivatives of Branched Aliphatic Carboxylic Acids with 4-Aminobenzensulfonamide

  摘要：

  Despite the availability of 14 new antiepileptic drugs (AEDs), about 30% of epileptic patients are not seizure-free. Consequently there is substantial need to develop new effective AEDs. A novel class of aromatic amides composed of phenylacetic acid or branched aliphatic carboxylic acids, with five to nine carbons in their carboxylic moiety, and aminobenzenesulfonamide were synthesized and evaluated in the anticonvulsant rat-maximal electroshock (MES) and subcutaneous metrazol seizure (scMet) tests. Fourteen of the synthesized amides had an anticonvulsant ED(50) of <50 mg/kg in the rat-MES test. The amides 2-methyl-N-(4-sulfamoylphenyl)butyramide (10), 2-ethyl-N-(4-sulfamoylphenyl)butyramide (11), and 3,3-dimethyl-N-(4-sulfamoylphenyl)butyramide (15) were the most potent compounds possessing MES-ED(50) values of 7.6, 9.9, and 9.4 mg/kg and remarkable protective index (PI = TD(50)/ ED(50)) values of 65.7, 50.5, and 53.2, respectively. These potent sulfanylamides caused neural tube defects only at doses markedly exceeding their effective dose. The anticonvulsant properties of these compounds make them potential candidates for further development as new, potent, and safe AEDs.

  Valproic acid (VPA, 1) is a major broad spectrum antiepileptic and central nervous system drug widely used to treat epilepsy, bipolar disorder, and migraine. VPA’s clinical use is limited by two severe and life-threatening side effects, teratogenicity and hepatotoxicity. A number of VPA analogues and their amide, N-methylamide and urea derivatives, were synthesized and evaluated in animal models of
