that the analgetic properties displayed by compounds 1--3 are associated, mainly, with the 2-amino-1,3-thiazine ring system. In the 2-acylimino series, evidence is presented suggesting a contribution to the observed activity on the part of the spiroannulated ether ring as well. Both 1a and its p-fluorobenzoyl derivative 33 exhibit analgesic activity in the rat tail-flick assay.
(+/-)-2-Amino-7-oxa-3-thia-1-azaspiro [5,5] undec-1-ene(1a)及其许多衍生物在苯醌扭曲和酵母菌引起的足部发炎中表现出显着活性分析。为了建立结构-活性关系,相关的螺杂环,(+/-)-2-氨基-7-氧杂-3-硫杂-1-硫杂螺[5,4]癸-1-烯(2),(+ /-)-2-氨基-3-thia-1-azaspiro [5,5]十一碳-1-烯(3)和(+/-)-2-氨基-7-oxa-1-azaspiro [5, 5] undec-1-ene(4)被检测。在这些化合物中,只有4个未能显示活性,表明化合物1--3表现出的止痛特性主要与2-氨基-1,3-噻嗪环系统有关。在2-acylimino系列中,提供了证据表明螺环化的醚环也对观察到的活性有贡献。
