New μ-opioid receptor (MOR) agonists containing 4-hydroxypiperidine, piperidine and piperazine moieties were synthesized and evaluated to find a peripheral opioid analgesic. Among the synthesized compounds, [2-[1-[3-(N,N-dimethylcarbamoyl)-3,3-diphenylpropyl]-4-hydroxypiperidin-4-yl]phenoxy]acetic acid (8: SS620) having phenoxyacetic acid and 4-hydroxypiperidine moieties showed the highest agonist potency on the MOR in an isolated guinea-pig ileum preparation, and it also had selectivity to the human MOR expressed in Chinese hamster ovary (CHO)-K1 cells compared with the same types of δ- and κ-opioid receptors (DOR and KOR). In addition, compound 8 showed a 10 times more potent MOR agonist activity than loperamide. Furthermore, compound 8 showed a peripheral analgesic activity in vivo screening on rat.
合成并评估了含有 4-羟基哌啶、哌啶和哌嗪分子的新型μ-阿片受体(MOR)激动剂,以寻找一种外周阿片类镇痛药。在合成的化合物中,[2-[1-[3-(N,N-二甲基氨基甲酰基)-3,3-二苯基丙基]-4-羟基哌啶-4-基]苯氧基]乙酸(8:在离体豚鼠回肠制剂中,具有苯氧乙酸和 4-羟基哌啶分子的 SS620 对 MOR 的激动效力最高,与同类型的 δ- 和 κ- 阿片受体(DOR 和 KOR)相比,它对中国仓鼠卵巢(CHO)-K1 细胞中表达的人类 MOR 也具有选择性。)此外,化合物 8 显示出的 MOR 激动剂活性是洛哌丁胺的 10 倍。此外,化合物 8 在大鼠体内筛选中显示出外周镇痛活性。
