Buprenorphine is widely used as an analgesic drug and it is also increasingly considered for maintenance and detoxification of heroin addicts. It is a potent micro -receptor partial agonist with a long duration of action. An inverted U-shaped dose-effect curve

NalBzoH (6-desoxy-6-benzoylhydrazido-N-allyl-14-hydroxydihydronomorphin one) is a novel opiate with potent actions at both mu and kappa receptors. Analgesic studies in mice examining increasing doses of NalBzoH with a fixed dose of morphine revealed a biphasic curve. NalBzoH at doses as low

Actions of nociceptin on electrical and synaptic behavior of morphologically and neurochemically identified neurons in the guinea pig duodenal myenteric plexus were studied with conventional techniques. Nociceptin hyperpolarized the membrane potential in 104 of 121 AH-type and 28 of 51

Mu-opioid receptor agonists are a mainstay of clinical analgesia, despite the significant unwanted effects and dependence liability associated with drugs like morphine. The quest for opioids that produce analgesia with fewer undesirable effects has lead to the putative identification of

The presence of pairs of basic amino acids within the orphanin FQ/Nociceptin (OFQ/N) sequence has raised the possibility that truncated versions of the peptide might be physiologically important. OFQ/N(1-11) is pharmacologically active in mice, despite its poor affinity in binding
