Ki: 0.16 nM (α1a-adrenoceptor), 24.9 nM (α1b- adrenoceptor), 0.92 nM (α1d-adrenoceptor), 92 nM (Human α2a-adrenoceptor), 22 nM (Human α2c-adrenoceptor), 21 nM (Rat α2b-adrenoceptor), 29 nM (Rat 5HT1A receptor)[1]
Fiduxosin displays low affinity for other adrenoceptors, including cloned human α2a- (92 nM) and α2c-adrenoceptors (22 nM) and rat neonatal lung α2b-adrenoceptors (21 nM), in addition to β-adrenoceptors (2-5 μM). Fiduxosin also has low affinity for 5HT1A receptors in rat cortex (29 nM) compared with its affinity at α1a-adrenoceptors (0.16 nM). Fiduxosin antagonizes competitively PE-induced responses with a pA2 value of 7.58, in the rabbit urethra[1].

プロトコル
Male beagle dogs (>2 years old, 12-15 kg) are chronically instrumented for the continuous measurement of arterial blood pressure by implanting a telemetry transducer/transmitter (TA11PA-C40) into a carotid artery. On test day, dogs are placed in sling restraints and an Abbocath-T i.v. catheter (18-G) is inserted into a cephalic vein for blood sampling and for the administration of agonist. Prostatic intraurethral pressure (IUP) is measured using a transurethral 7F Swan-Ganz balloon catheter (41224-01). Dose responses of the intraurethral and arterial pressor effects of 8, 16, and 32 μg/kg i.v. phenylephrine (PE) are obtained before and at various time points after a single p.o. dose of an antagonist. Fiduxosin is dissolved in a vehicle of 20% ethanol, 30% propylene glycol, and 50% water. Terazosin and tamsulosin are dissolved in water. All antagonists are given by gavage in a volume of 1 mL/kg. PE is dissolved in saline and administered in a volume of 0.1 mL/kg. The increase in IUP or mean arterial pressure (MAP) caused by PE is allowed to return to baseline before the next dose is administered.
