kg(-1) os dose, some compounds 3 and 4 showed notable analgesic or anti-inflammatory activity but no antipyretic properties, whereas the 5-(dibutylamino) derivatives 5b and 5f proved to be significantly endowed with all these activities. Almost all the compounds 3, 4 and 5 did not show acute toxicity in mice up to 800 mg kg(-1) os dose.
适当的N,N-二烷基-4H- [1,2,4]三唑[4,3-a] [1,5]苯并二氮杂-5-胺(1)与N-氯代琥珀酰亚胺的反应得到其4-氯代衍生物3依次用环胺处理,得到相应的4,5-二氨基衍生物4。N,N-二烷基-4H-咪唑并[1,2-a] [1,5]苯并二氮杂-5-胺(5)为由适合的4-(二烷基氨基)-1,3-二氢-2H-1,5-苯并二氮杂-2--2-酮(8)开始,通过多步合成路线制备。在200 mg kg(-1)os剂量下,某些化合物3和4表现出明显的止痛或抗炎活性,但没有解热特性,而5-(二丁基氨基)衍生物5b和5f被证明具有所有这些活性。 。几乎所有化合物3、4和5在800 mg kg(-1)os剂量的小鼠中均未显示急性毒性。
