Gelsemine, an alkaloid from the Chinese herb Gelsemium elegans, is effective in mitigating chronic pain. Antinociceptive and hypnotic effects.
Gelsemine is an effective agent for treatment of both neuropathic pain and sleep disturbance in partial sciatic nerve ligation (PSNL) mice. Gelsemine (4 mg/kg) exerts analgesic effects on PSNL-induced mechanical allodynia and thermal hyperalgesia. In PSNL mice, Gelsemine (2 and 4 mg/kg) increases the mechanical threshold for 4 h and prolonged the thermal latencies for 3 h. Furthermore, Gelsemine (4 mg/kg, administered at 6:30 AM) increases non-rapid eye movement (non-REM, NREM) sleep, decreases wakefulness, but does not affect rapid eye movement (REM) sleep during the first 3 h in PSNL mice[1]. Immunohistochemical study shows that PSNL increases c-Fos expression in the neurons of the anterior cingulate cortex, and Gelsemine (4 mg/kg) decreases c-Fos expression by 58%[1].

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
