Both series of N-substituted derivatives of 1-arylimidazolidyn-2-ylideneureas were subjected to cyclization to respective imidazo[1,2-a][1,3,5]triazines. Chain and cyclic compounds bearing ester moiety affected spontaneous locomotor activity, body temperature of mice as well as showed antinociceptive and serotoninergic activity. Interestingly, their antinociceptive activity was not reversed by naloxone
设计了一系列20种N-取代的1-芳基咪唑啉-2-吡喃神经酰胺衍生物及其环化产物,作为具有双重抗伤害感受性和5-羟色胺能活性的化合物。由[1-芳基-4,5-二氢-1H-咪唑-2-胺和异氰酸根合乙酸乙酯]制备[(((1-芳基咪唑啉-2-亚胺基氨基甲酰基)氨基甲酰基]氨基}乙基]乙酸乙酯,然后用氨溶液将其转化为2- [((1-苯基咪唑烷基-2-亚甲基)氨基甲酰基]氨基}乙酰胺。将1-芳基咪唑啉基-2-基神经脲的两个系列的N-取代衍生物进行环化成各自的咪唑并[1,2-a] [1,3,5]三嗪。带有酯部分的链状和环状化合物会影响小鼠的自发运动能力,体温以及抗伤害性和5-羟色胺能活性。有趣的是,它们的抗伤害感受活性没有被纳洛酮逆转,因此它不是通过阿片样物质系统介导的。带有酰胺部分的链状和环状化合物缺乏中枢神经系统(CNS)活性,这可能归因于亲油性低(极性表面积过大和分子体积过小)和血脑屏障渗透性差。
