Naldemedine (Synonyms:S-297995)
目录号 : KM15545 CAS No. : 916072-89-4 纯度 : 98%

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)。

生物活性

Naldemedine (S-297995) is an orally active, peripherally acting µ-opioid receptor antagonist. Naldemedine shows potent binding affinities (IC50s = 1.15, 1.11, and 1.5 nM, repectively) and antagonist activities (IC50s= 25.57, 7.09, 16.1 nM, repectively) for recombinant human μ-, δ-, and κ- opioid receptors. Naldemedine tempers opioid-induced constipation (OIC) without compromising opioid analgesia.

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 ED50s ± 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).
