英文摘要 | (-)-Naringenin 40,7-dimethyl ether ((-)-NRG-DM) was isolated for the first time by our lab from Nardostachys jatamansi DC, a traditional medicinal plant frequently used to attenuate pain in Asia. As a natural derivative of analgesic, the current study was designed to test the potential analgesic activity of (-)-NRG-DM and its implicated mechanism. The analgesic activity of (-)-NRG-DM was assessed in a formalin-induced mouse inflammatory pain model and mustard oilinduced mouse colorectal pain model, in which the mice were intraperitoneally administrated with vehicle or (-)-NRG-DM (30 or 50 mg/kg) (n = 10 for each group). Our data showed that (-)-NRGDM can dose dependently (30~50 mg/kg) relieve the pain behaviors. Notably, (-)-NRG-DM did not affect motor coordination in mice evaluated by the rotarod test, in which the animals were intraperitoneally injected with vehicle or (-)-NRG-DM (100, 200, or 400 mg/kg) (n = 10 for each group). In acutely isolated mouse dorsal root ganglion neurons, (-)-NRG-DM (1~30 _M) potently dampened the stimulated firing, reduced the action potential threshold and amplitude. In addition, the neuronal delayed rectifier potassium currents (IK) and voltage-gated sodium currents (INa) were significantly suppressed. Consistently, (-)-NRG-DM dramatically inhibited heterologously expressed Kv2.1 and Nav1.8 channels which represent the major components of the endogenous IK and INa. A pharmacokinetic study revealed the plasma concentration of (-)-NRG-DM is around 7 _M, which was higher than the effective concentrations for the IK and INa. Taken together, our study showed that (-)-NRG-DM is a potential analgesic candidate with inhibition of multiple neuronal channels (mediating IK and INa). |
