生物活性
描述 Alvimopan, a peripherally acting mu-opioid receptor antagonist, is a novel agent for the treatment of postoperative ileus[3]. Alvimopan inhibits the loperamide-stimulated [35S]GTPγS binding to membranes containing the cloned human μ-opioid receptor, with an IC50 of 1.7 nM[4]. 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[5]. Mesenteric afferent fibres are markedly stimulated by mu-opioid receptor agonists, an effect blocked by alvimopan, which may contribute to the gastrointestinal reflex and behavioural responses to opiate treatment or abuse[6].
