Investigation into species variants in tachykinin NK1 receptors by use of the non-peptide antagonist, CP-96,345
Abstract
The affinity of the non-peptide antagonist CP-96,345 for tachykinin NK1 receptors has been estimated in a range of species by use of both radioligand binding and functional assays. CP-96,345 was 30-120 fold less active at NK1 receptors in rat and mouse than in the other species examined, including man. These results demonstrate the existence of species variations in NK1 receptors.
