常见问题列表
生物活性
Nalfurafine (TRK-820) 是一种强效选择性，具有口服活性的 G 蛋白偏倚 kappa opioid receptor (KOR) 激动剂，具有很高的转化潜力。Nalfurafine (TRK-820) 增强了 MOR 靶向镇痛药的生物学作用，它还有潜力用于尿毒症瘙痒研究的相关研究。
靶点
IC50: kappa opioid receptor (KOR)
体内研究
Nalfurafine (subcutaneous injection; 0.015 mg/kg) combines with EOM-salvinorin-B produces spinal antinociception equivalent to 5 mg/kg, it also enhances the supraspinal analgesic effect of 5 mg/kg morphine. Nalfurafine (subcutaneous injection; 4 μg/kg) causes a dose-dependent increase of the inhibition of the acetic acid-induced abdominal constriction,and the inhibition of the abdominal constriction reaches its peak 30 min after injection, gradually declined and returned to the preinjection level 4 hr after.
