A series of 3-(aminoalkyl)- and 3-[(4-aryl-1-piperazinyl)alkyl]oxazolo[4,5-b]pyridin-2(3H)-ones were prepared from their respective oxazolo[4,5-b]pyridin-2(3H)-ones. Several members of this group were found to possess potent analgesic activity in the mouse during a p-phenylquinone writhing induced test. Among them, phenylpiperazine compounds with two-carbon length alkyl chains, 2a and 2b, appeared
由它们各自的恶唑并[4,5]制备了一系列的3-(氨基烷基)-和3-[(4-芳基-1-哌嗪基)烷基]恶唑并[4,5-b]吡啶-2(3H)-。 -b] pyridin-2(3H)-ones。在对苯醌扭体诱导试验中,发现该组的几名成员在小鼠中具有有效的镇痛活性。其中,具有两碳长度烷基链的苯基哌嗪化合物2a和2b以高止痛剂出现,几乎没有毒性,既不具有抗炎作用也不具有阿片样物质受体亲和力。详细介绍了该系列的合成和结构亲和关系。
