Problems solved by technology

Opioid analgesics have strong analgesic effects, but long-term use can easily lead to tolerance, dependence, and addiction, and have adverse reactions such as respiratory depression and central sedation. They are currently used for acute sharp pain and severe cancer pain.
Non-steroidal anti-inflammatory drugs only exert a moderate degree of analgesic effect and are suitable for mild and moderate chronic dull pain, but are ineffective for sharp pain caused by direct stimulation of sensory extremities. In addition, they also have adverse reactions such as gastrointestinal bleeding and cardiotoxicity

Embodiment 1

[0053] Example 1. Evaluation of the analgesic effect of 071031B by mouse acetic acid writhing method

[0054] 1. Experimental animals:

[0055] KM mouse, male, SPF grade, 22-25g,

[0056] The animals were purchased from the Experimental Animal Center of the Academy of Military Medical Sciences and bred in the Experimental Animal Center of the Academy of Military Medical Sciences.

[0057] 2. Test sample:

Embodiment 2

[0058] 071031B, its structural formula is Prepared according to the method of Example 2 of the patent application CN101613347A;

[0059] Duloxetine hydrochloride (Zhejiang Haixiang Pharmaceutical Co., Ltd.).

[0060] 3. Experimental method:

[0061] After oral administration of test drug 071031B or positive drug duloxetine in mice for 30 minutes, each mouse was intraperitoneally injected with 2% acetic acid aqueous solution 0.1ml / 10g, and the number of times of writhing of each mouse in 5-20 minutes was observed and recorded, namely The body twisting or elongation of the mouse with concave abdomen was counted as one writhing response. Compared with the control group, if the number of writhing reactions decreases, it means that there is a certain analgesic effect.
