摘要: Abstract The non-peptide angiotensin II (AII) receptor subtype selective antagonist, DuP 753, was used to characterize AII binding sites in the rat brain. 753 competed for specific 125 I-[Sar 1 , Ile 8 ]AII ( I-SIAII) many brain nuclei (IC 50 = 20−30 nM), but a weak competitor at remaining > 10 −4 M). sensitive (designated α subtype) correspond with areas where is inhibited by sulfhydryl reducing agents, whereas insensitive (AII β ) not agents.
