英文摘要 | The binding affinity of ohmefentanyl stereoisomers for mu-opioid receptors and the effect of chronic ohmefentanyl stereoisomers pretreatments on intracellular cAMP formation were investigated in Sf9 insect cells expressing human mu-opioid receptors (Sf9-mu cells). Competitive assay of [H-3]ohmefentanyl binding revealed that these isomers had high affinity for mu-opioid receptors in Sf9-mu cells. Isomer F9204 had the highest affinity for mu-opioid receptors with the K-i value of 1.66 +/- 0.28 nM. After pretreated Sf9-mu cells with increasing concentrations of these isomers for 6 h, addition of naloxone (1 muM) precipitated an overshoot of foskolin-stimulated cAMP accumulation. The ability of these isomers to induce cAMP overshoot differed greatly with the order of F9202 > F9205 > F9208 > F9206 > F9204 > F9207. Of these isomers, F9202 was 2.7-fold less potent than F9204 in receptor binding affinity, but 71.5-fold more potent in ability to induce cAMP overshoot. These results suggested that there was a significant stereo-structural difference among ohmefentanyl stereoisomers in ability to induce naloxone-precipitated cAMP overshoot in Sf9-mu cells.
