一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
作为一种降压药,Guanfacine是α2A-肾上腺素受体(α2AR)的选择性激动剂,其Kd值为31 nM,比α2B-肾上腺素受体高出60倍的选择性。
在五项选择连续反应时间任务(5-CSRTT)中,低剂量Guanfacine能够提高NK1R敲除小鼠的注意力,而对野生型小鼠没有影响。高剂量Guanfacine处理能抑制NK1R敲除和野生型小鼠的冲动[1]。
Guanfacine能够降低高酒精消费大鼠中酒精的摄入量。Guanfacine处理能降低大鼠酒精剥夺效应(ADE),减少酒精需求和线索/启动介导的酒精需求恢复[2]。
脊神经结扎诱导的大鼠模型中,Guanfacine能降低C纤维诱发的场电位,该效应受δ受体(DOR)拮抗剂纳曲吲哚处理而降低,但不受μ受体(MOR)拮抗剂CTOP的影响。相反地,Guanfacine能增加DOR激动剂δ啡肽II,而非MOR激动剂DAMGO介导的对C纤维诱发的脊髓场电位的抑制。此外,低剂量Guanfacine与δ啡肽II协同给药能增强神经结扎大鼠中δ啡肽II介导的稳定热和机械镇痛效应的产生[3]。
