Twenty four new 1-[(4-phenylpiperazin-1-yl)-methyl]- derivatives of 3-phenyl-3-methyl- (6–17) and 3,3-dimethyl-pyrrolidine-2,5-diones (18–29) have been synthesized and evaluated for their anticonvulsant activity in the maximum electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) seizure tests after intraperitoneal injection in mice. The acute neurological toxicity was determined using the
二十四个新的1 - [(4-苯基哌嗪-1-基) -甲基] - 3-苯基-3-甲基- (的衍生物6 - 17)和3,3-二甲基-吡咯烷-2,5-二酮类(18 - 29)已被合成并评价在最大电他们的抗惊厥活性(MES)和皮下戊四唑(SC在小鼠腹膜内注射后PTZ)癫痫发作的测试。使用旋转棒屏幕测定急性神经毒性。虽然没有抗咬合性均在发现SCPTZ屏幕上,有14种化合物在电诱发的癫痫发作中显示出保护作用。口服给药后,在大鼠中测试了来自这些分子的七种化合物(MES测试)。在整个系列中,对大鼠最有效的是1-[4-(4-氟苯基)-哌嗪-1-基}-甲基] -3-甲基-3-苯基-吡咯烷-2,5-二酮(8) ED 50值为7.78 mg / kg,它是3-氯苯基- (10)和3,4-二氯苯基-(12)类似物,ED 50值为27.93 mg / kg和15.11 mg / kg。为了解释作用的可能机制的最活跃
