title: Synthesis of a selective alpha-2A adrenoceptor antagonist, BRL 48962, and its characterization at cloned human alpha-adrenoceptors.
abstract: The chiral synthesis of the potent and selective alpha-2A antagonist, BRL 48962, is described. Evaluation of BRL 48962 at cloned human alpha-adrenoceptors indicates that this antagonist has a selectivity in the order of 30-fold for the alpha-2A subtype.
