The effects of the selective alpha2-adrenergic agonist p-aminoclonidine, the nonselective adrenergic agonist epinephrine, the selective beta2-adrenergic agonist fenoterol and the adenosine A1 agonist R-PIA on intraocular pressure were studied in control and pertussis toxin-pretreated rabbits. Pretreatment of rabbits with pertussis

We have compared bacteriorhodopsin-based (alpha(2A)-AR(BR)) and rhodopsin-based (alpha(2A)-AR(R)) models of the human alpha(2A)-adrenengic receptor (alpha(2A)-AR) using both docking simulations and experimental receptor alkylation studies with chloroethylclonidine and 2-aminoethyl methanethiosulfonate hydrobromide. The results indicate that the alpha(2A)-AR(R) model provides a better

The localization of alpha 2-receptors was determined by quantitative autoradiography using [125I]para-iodoclonidine ([125I]PIC) and [3H]para-aminoclonidine ([3H]PAC). In cortical tissue, [125I]PIC and [3H]PAC were equipotent in their capacity to bind sites recognized by oxymetazoline (preferentially binds to the alpha 2A receptor
