Alvimopan is a μ-opioid receptor antagonist (K = 0.47 nM). It is selective over the κ- and δ-opioid receptors (Ks= 100 nM and 12 nM, respectively). Alvimopan inhibits μ-opioid receptor-mediated GTP binding to CHO cell membranes with an IC value of 1.7 nM. It inhibits morphine-induced slowing of colorectal transit in mice with an ED value of 0.41 mg/kg. Alvimopan (0.3 and 1 mg/kg, p.o.) reduces inhibition of gastrointestinal (GI) transit induced by morphine, but not apraclonidine , in rats. Formulations containing alvimopan have been used in the treatment of opioid-induced bowel dysfunction.
Alvimopan (ADL 8-2698) is a potent, selective, orally active and reversible μ-opioid receptor antagonist, with an IC50 of 1.7 nM. Alvimopan has selectivity for μ-opioid receptor (Ki=0.47 nM) over κ- and δ-opioid receptors (Kis=100, 12 nM, respectively). Alvimopan can be used for the research of postoperative ileus.
IC50&Target
IC50: 1.7 nM (μ-opioid receptor)
体外研究
Alvimopan inhibits the loperamide-stimulated [35S]GTPγS binding to membranes containing the cloned human μ-opioid receptor, with an IC50 value of 1.7 nM.
体内研究
Alvimopan (0.1-1.0 mg/kg; p.o.) partially antagonizes the slowing of small intestinal transit of 113Sn-labelled microspheres produced by morphine in rats.
Alvimopan (3 mg/kg; p.o.) has no effect on the visceromotor behavioural responses (VMR) induced by noxious colorectal distension (CRD) in conscious rats.
