生物活性
Naldemedine (S-297995) 是一种口服活性、外周作用的 µ-opioid 受体拮抗剂。Naldemedine 对 μ-阿片受体、δ-阿片受体、κ-阿片受体具有较强的结合亲和力 (IC50 分别为1.15、1.11 和 1.5 nM) 和拮抗活性 (IC50 分别为 25.57、7.09 和 16.1 nM)。Naldemedine 在不影响阿片镇痛作用的情况下缓解阿片类药物所致便秘 (OIC)。体内研究
Naldemedine (S-297995) (0.001-10 mg/kg; p.o.) significantly represses the opioid-induced inhibition of small intestinal transit in rats. In the subcutaneous Morphine-induced inhibition model, the ED 50 s ± standard error of the mean is 0.03 ± 0.02 mg/kg for Naldemedine. Subcutaneous morphine-inhibited castor oil-induced diarrhea in rats, and pretreatment with Naldemedine 0.03-1 mg/kg significantly reverses this effect.
| Animal Model: | 6-week-old Crlj: WI male rats |
| Dosage: | 0.001-10 mg/kg |
| Administration: | P.o. |
| Result: | Significantly repressed the opioid-induced inhibition of small intestinal transit in rats by subcutaneous morphine (P < 0.05 or P < 0.01 for naldemedine 0.03-10 mg/kg), and oxycodone (P < 0.01 for naldemedine 0.03-3 mg/kg). |
