英文摘要 | Aim: To characterize the pharmacological profiles of a novel κ-opioid receptor agonist MB-1C-OH. Methods: ~3Hdiprenorphine binding and ~(35)SGTPγS binding assays were performed to determine the agonistic properties of MB-1C-OH. Hot plate, tail flick, acetic acid-induced writhing, and formalin tests were conducted in mice to evaluate the antinociceptive actions. Forced swimming and rotarod tests of mice were used to assess the sedation and depression actions. Results: In ~3Hdiprenorphine binding assay, MB-1C-OH did not bind to μ- and δ-opioid receptors at the concentration of 100 μmol/L,but showed a high affinity for κ-opioid receptor (K_1=35 nmol/L). In ~(35)SGTPγS binding assay, the compound had an E_(max) of 98% and an EC_(50) of 16.7 nmol/L for κ-opioid receptor. Subcutaneous injection of MB-1C-OH had no effects in both hot plate and tail flick tests, but produced potent antinociception in the acetic acid-induced writhing test (ED_(50)=0.39 mg/kg), which was antagonized by pretreatment with a selective κ-opioid receptor antagonist Nor-BNI. In the formalin test, subcutaneous injection of MB-1C-OH did not affect the flinching behavior in the first phase, but significantly inhibited that in the second phase (ED_(50)=0.87 mg/kg). In addition, the sedation or depression actions of MB-1C-OH were about 3-fold weaker than those of the classical k agonist (-)U50,488H. Conclusion: MB-1C-OH is a novel κ-opioid receptor agonist that produces potent antinociception causing less sedation and depression. |
