In several steps, 5, 14-O-dimethylnaltrexone (3) and 5, 14-O-dimethylnaloxone (4) were prepared starting from 5, 14-O-dimethyloxycodone (5). Compound 3 exhibited opioid agonism in vitro (guinea-pig ileum and mouse vas deferens preparations) and antagonism in vivo (AcOH-writhing test in mice), while compound 4 was found to be an agonist in vitro and in vivo.
在几个步骤中,5,14- ø -dimethylnaltrexone(3)和5,14- ø -dimethylnaloxone(4制备从5开始),14- Ô -dimethyloxycodone(5)。化合物3在体外表现出阿片样物质激动作用(豚鼠回肠和小鼠输精管制剂),而在体内表现出拮抗作用(在小鼠中进行AcOH-扭体试验),而化合物4在体外和体内表现出激动剂作用。
