Incarvillea sinensis extract was used by Jia Yanxing team to develop a good preparation of incarvillea ester alkali and its structural analogs method, and systematically studies the analgesic activity, they find incarvillea ester alkali and its two structural analogues, on sexual nerve injury model of rats with formalin model, than the current treatment of neuralgia effect is the best drug gabapentin effect is better. These three kinds of compounds in 20 milligrams per kilogram of body weight using the curative effect of or 40 mg per kilogram of body weight and use 100 mg of gabapentin. As a result, experts believe that the three compounds can be used as a development of new type of important leading compounds in the treatment of neuropathic pain or drug candidates, deserves further research and development.
