10961736-5	1999	Similar studies in rabbit brain membranes found that prazosin and oxymetazoline were able to displace [3H]-RX821002 in a biphasic manner indicating the presence of subtypes of alpha2-adrenoceptors.	Prazosin	53-61	adrenoceptor alpha 2A	Rattus norvegicus	176-196	
1645350-11	1991	In competition binding studies the potency order of competing ligands for RG20 is phentolamine greater than idazoxan greater than yohimbine greater than rauwolscine greater than prazosin.	Prazosin	178-186	adrenoceptor alpha 2A	Rattus norvegicus	74-78	
7892112-3	1994	Activation of alpha 2-adrenoceptors by clonidine (an alpha 2-adrenoceptor agonist) or noradrenaline (a non-selective alpha-adrenoceptor agonist), both in the presence of 0.1 microM prazosin to block alpha 1-adrenoceptors, caused a slow and sustained increase in [Ca2+]i which was inhibited by 0.1 microM rauwolscine (an alpha 2-adrenoceptor antagonist).	Prazosin	181-189	adrenoceptor alpha 2A	Rattus norvegicus	14-35	
2556205-10	1989	The affinity estimate for prazosin in rat submaxillary gland was intermediate between its affinity at the alpha 2A- and alpha 2B-adrenoceptors while affinity estimates for idazoxan and phentolamine in rat submaxillary gland were greater than those obtained at either the alpha 2A- or alpha 2B-adrenoceptor.	Prazosin	26-34	adrenoceptor alpha 2A	Rattus norvegicus	271-305
