The binding profile of cyclazosin, a new prazosin-related alpha 1-adrenoceptor antagonist, at alpha 1-, alpha 2-adrenoceptors, dopamine D2 and 5-HT1A receptors was compared to that of 5-methylurapidil, spiperone, risperidone and other prazosin-related ligands. In addition, cyclazosin was investigated at native

The spleen is a reservoir for circulating blood cells, and can contract to expel them. We have investigated the adrenoceptors involved in isometric contractions of rat spleen produced by noradrenaline (NA) and the α1-adrenoceptor agonist phenylephrine (Phe). Contractions to NA

The enantiomers of [4-(4-amino-6, 7-dimethoxyquinazolin-2-yl)-cis-octahydroquinoxalin-1-yl]-fu ran- 2-ylmethanone (cyclazosin, 1) were synthesized from the chiral furan-2-yl(cis-octahydroquinoxalin-1-yl)methanone [(+)-2 and (-)-2], which were obtained by resolution of the racemic amine with (S)-(+)- and (R)-(-)-mandelic acid. The binding profile of the enantiomers of 1
