ABSTRACT
The central hypotensive action of clonidine and 26 structurally related derivatives was quantified by means of an ED30 obtained from dose-response curves following intravenous administration to anesthetized, normotensive rats. Multiple regression analyses of the biological data yielded correlation equations comprising a relationship between hypotensive activity and molecular structure. In the equations the pharmacokinetics together with the actual engagement of the central alpha-adrenoceptor are accounted for. More detailed characteristics of this central alpha-adrenoceptor emerged from correlation studies in which new ED30 values, associated with brain concentrations, were employed. The use of this biological parameter at the alpha-adrenoceptor level allowed the presentation of a hypothetical working model for the mechanism of interaction between this receptive site and clonidine-like imidazolidines.
