A new series of N-(4-chlor-2-methylphenoxy)ethyl- (1-6) and N-(4-chlor-2-methylphenoxy)acetylaminoalkanols (7-10) has been synthesized for evaluation of their anticonvulsant activity. Pharmacological tests included maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole seizure (ScMet) assays, as well as rotarod for neurotoxicity (TOX) and were performed in mice i.p. and rats p.o. The activity of the compounds in the group was various, and the most active compound in mice was R,S-1N-[(4-chlor-2-methylphenoxy)ethyl]aminopropan-2-ol, revealing 100% activity in MES test at 30 mg/kg b.w., 0.5 h after administration without toxicity at the same dose and time. In rats (p.o.), the most active compound was 2N-[(4-chlor-2-methylphenoxy)ethyl]amino-2-methylpropan-1-ol, revealing 25% activity in MES at 30 mg/kg b.w. 0.5 and 1 h after administration.
一系列新合成的N-(4-氯-2-甲基苯氧基)乙基-(1-6)和N-(4-氯-2-甲基苯氧基)乙酰氨基烷醇(7-10),用于评估其抗惊厥活性。药理测试包括最大电休克发作(MES)和皮下戊四氮发作(ScMet)试验,以及用于神经毒性的旋转棒(TOX),并在小鼠腹腔内和大鼠口服进行。该组化合物的活性各异,在小鼠中最活跃的化合物是R,S-1N-[(4-氯-2-甲基苯氧基)乙基]氨基丙-2-醇,在给药后0.5小时、30 mg/kg体重时,MES测试显示出100%的活性,且同一剂量和时间下无毒性。在大鼠(口服)中,最活跃的化合物是2N-[(4-氯-2-甲基苯氧基)乙基]氨基-2-甲基丙-1-醇,在给药后0.5和1小时、30 mg/kg体重时,MES中显示出25%的活性。
