A novel series of benzenesulfonamide derivatives containing 4-aminobenzenesul-fonamide and α-amides branched valproic acid or 2,2-dimethylcyclopropanecarboxylic acid moieties were synthesized and screened for their anticonvulsant activities in mice maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ) test. The activity experimental study showed that 2,2-dipropyl-N1-(4-sulfamoylphenyl)malonamide (18b) had the lowest median effective dose (ED50) of 16.36 mg/kg in MES test, and 2,2-dimethyl-N-(4-sulfamoylphenyl)cyclopropane-1,1-dicarboxamide (12c) had the lowest ED50 of 22.50 mg/kg in scPTZ test, which resulted in the protective indexe (PI) of 24.8 and 20.4, respectively. These promising data suggest the new compounds have good potential as new class of anticonvulsant agents with high effectiveness and low toxicity for the treatment of epilepsy.
合成了一系列新型苯磺酰胺衍生物,这些衍生物含有4-氨基苯磺酰胺和α-酰胺支链的丙戊酸或2,2-二甲基环丙烷羧酸基团,并对小鼠的最大电刺激癫痫(MES)和皮下戊二唑(scPTZ)测试进行了筛选。活性实验研究表明,2,2-二丙基-N1-(4-磺酰苯基)丙二胺(18b)在MES测试中具有最低的中位有效剂量(ED50)为16.36 mg/kg,而2,2-二甲基-N-(4-磺酰苯基)环丙烷-1,1-二羧酰胺(12c)在scPTZ测试中具有最低ED50为22.50 mg/kg,导致保护指数(PI)分别为24.8和20.4。这些有前景的数据表明,这些新化合物作为新类抗癫痫药物在有效性高且毒性低方面具有良好的潜力,可用于癫痫的治疗。
