纳呋拉啡 用途与合成方法

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。

IC50: kappa opioid receptor (KOR)

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.

Animal Model: Male and Female C57BL/6J mice
Dosage: 0.015 mg/kg
Administration: Subcutaneous injection
Result: Had the potential for enhancing the therapeutic potential of MOR-targeting analgesics, such as morphine.
