As a result, we identified (5S)-6-methyl-1,3,4,5,6,8-hexahydro-7H-2,5-methano[1,5]diazonino[7,8-b]indol-7-one sulfate salt, 15a (DS54360155), with a unique and original bicyclic skeleton, as an analgesic more potent than conolidine. Moreover, 15a did not exhibit mu-opioid receptor agonist activity.
我们合成了天然生物碱,可可定的衍生物,并在口服后在ddY小鼠中的乙酸诱导的扭体试验和福尔马林试验中评估了这些衍生物。结果,我们确定了(5 S)-6-甲基-1,3,4,5,6,8-六氢-7H-2,5-甲基[1,5]重氮基[7,8-b]吲哚-7-硫酸盐15a(DS54360155)具有独特的原始双环骨架,比可可啶具有更强的镇痛作用。此外,15a没有表现出μ阿片受体激动剂活性。
