Development of an affinity ligand for purification of alpha 2-adrenoceptors from human platelet membranes.

Journal Article

Human platelets contain alpha 2-adrenoceptors which are negatively coupled to the enzyme adenylate cyclase. In order to better understand the interaction of this subtype of alpha receptor with this key enzyme, we have initiated a program to isolate and characterize the alpha 2-adrenoceptor. This report describes the synthesis and biological characterization of a series of molecules that were prepared as affinity ligands for this purpose. The best of these is 9-(allyloxy)-6-chloro-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (SK&F 101253). This compound is an alpha 2-adrenoceptor antagonist, which was obtained by synthetic modification of 6-chloro-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepine (SK&F 86466), a novel antagonist with high affinity for the alpha 2-receptor.
