A series of 1-(substituted benzyl)-3,4,5,6-tetrahydro-2(1H)-pyrimidones was synthesized primarily by catalytic hydrogenation of the corresponding 1-(substituted benzyl)-2(1H)-pyrimidone. The pharmacological evaluation of these compounds in mice revealed a unique profile that included evidence of CNS stimulation and depression within the series and in the same compounds. Some members of this series
一系列的1-(取代的苄基)-3,4,5,6-四氢-2(1H)-嘧啶主要是通过相应的1-(取代的苄基)-2(1H)-嘧啶酮的催化加氢合成的。这些化合物在小鼠中的药理学评估显示其独特的特性,包括该系列以及同一化合物中中枢神经系统刺激和抑制的证据。该系列的某些成员仅诱发中枢神经系统刺激的体征,某些化合物仅引起中枢神经系统抑制和骨骼肌松弛的体征,而某些化合物引起同一动物中刺激和抑制的体征。在基于丁苯那嗪拮抗作用的抗抑郁试验和对多种惊厥剂的拮抗作用的抗焦虑/抗惊厥试验中,进一步评估了这种明显的双重活性。4-氯,4-氟,4-溴和3,在相同的剂量范围内,4-二氯苄基化合物表现出抗抑郁和抗焦虑活性。在这四种化合物中,3,4-二氯苄基化合物的ED50值最低,为抗丁苯那嗪(17 mg / kg,口服)和抗戊烯四唑(23 mg / kg,po)。4-氟化合物在相同剂量范围内(相当于口服50 mg / kg)拮抗
