shown to be safer alternatives, the most notable was methyl 4-[(p-bromophenyl)amino]-6-methyl-2-oxocyclohex-3-en-1-oate, 13. Compound 13 had an ip ED50 of 4 mg/kg in the rat and a TD50 of 269 mg/kg, providing a protective index (TD50/ED50) of > 67. By variation in the ring size, additional aromatic substitutions and the synthesis of acyclic analogs, these newer compounds provide a more definitive insight
该报告继续对4-[(对氯苯基)氨基] -6-甲基-2-氧代环己基-3-烯-1-酸酯1(ADD 196022)和甲基4-(苄基氨基)进行深入评估-6-甲基-2-氧代环己基-3-烯-1-酸酯,2个,两个有效的抗惊厥性烯胺酮。这些化合物采用杏仁核点燃模型进行评估。1和2都没有针对杏仁核点燃的癫痫发作的活性,进一步支持了角膜点燃的模型作为抗电击癫痫发作评估的确定工具,如先前报道。关于1的其他腹膜内(ip)数据显示,在100 mg / kg的24小时内有毒性。为了使毒性最小化,已经制备了几种活性类似物。在由抗癫痫药物开发(ADD)计划开发的特殊ip大鼠屏幕中,对这些新的类似物进行了评估,以防最大剂量10 mg / kg的电击惊厥(MES)和100 mg / kg的神经毒性。从该筛选中,显示出几种化合物是更安全的替代品,最引人注目的是4-[((对-溴苯基)氨基] -6-甲基-2-氧代环己基-3-en-
