BioAssay: AID 779576

Binding affinity to human mu opioid receptor by radio-ligand binding assay

The concept of "ligand bias" at G protein coupled receptors has been introduced to describe ligands which preferentially stimulate one intracellular signaling pathway over another. There is growing interest in developing biased G protein coupled receptor ligands to yield safer, better tolerated, and more efficacious drugs. The classical mu opioid morphine elicited increased efficacy and more ..

Description:
Title: Structure-activity relationships and discovery of a G protein biased mu opioid receptor ligand, [(3-methoxythiophen-2-yl)methyl]({2-[(9R)-9-(pyridin-2-yl)-6-oxaspiro-[4.5]decan-9-yl]ethyl})amine (TRV130), for the treatment of acute severe pain.

Abstract: The concept of "ligand bias" at G protein coupled receptors has been introduced to describe ligands which preferentially stimulate one intracellular signaling pathway over another. There is growing interest in developing biased G protein coupled receptor ligands to yield safer, better tolerated, and more efficacious drugs. The classical mu opioid morphine elicited increased efficacy and duration of analgesic response with reduced side effects in beta-arrestin-2 knockout mice compared to wild-type mice, suggesting that G protein biased mu opioid receptor agonists would be more efficacious with reduced adverse events. Here we describe our efforts to identify a potent, selective, and G protein biased mu opioid receptor agonist, TRV130 ((R)-30). This novel molecule demonstrated an improved therapeutic index (analgesia vs adverse effects) in rodent models and characteristics appropriate for clinical development. It is currently being evaluated in human clinical trials for the treatment of acute severe pain.
