Inhibition binding curves for human adrenoceptors of 3H-rauwolscine (1 nM) in CHO membranes expressing, hα2A-adrenoceptor (12 µg) with yohimbine (▴) and ρ-Da1b (○) and membranes expressing hα2B (11 µg, ) or hα2C-adrenoceptor (3.1 µg, •) with ρ-Da1b. Inhibition of 3H-prazosin (1 nM) by ρ-Da1b in CHO membranes expressing hα1A-adrenoceptor (3.8 µg).
