Auriculin A
Auriculin A is a synthetic atrial natriuretic factor (ANF) with hemodynamic effect. Auriculin A antagonizes renal vasoconstriction in the dog, and influences on arterial baroreflex control of heart rate, systemic blood pressure, and perfusion pressure in the hind limb (perfused at constant flow) in rabbits.

Biological Activity
Auriculin A (2 μg/kg prime, 0.2 μg/kg/min; i.v.; for 45 min) influences on arterial baroreflex control of heart rate, systemic blood pressure, and perfusion pressure in the hind limb (perfused at constant flow) in rabbits[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Female mongrel dogs used in early clamp experiments (15-20 kg, anesthetized with 30 mg/kg pentobarbital sodium i.v.)[1]
-
Dosage:0.3 μg/min/kg
-
Administration:Intravenous injection; last for 30 min
-
Result:Increased glomerular filtration rate (GFR) 16±4% and Na excretion (UNa V) 261±63%, whereas it decreased urine osmolality (Uosm) 36±7% without changing free water clearance.
Also increased diuresis (V) and kaliuresis (UKV).

Animal Model:New Zealand white male rabbits (3-3.5 kg, anesthetized with 50 mg/kg Chloralose (HY-B1020) and 500 mg/kg Urethane (HY-B1207) i.v.)[2]
-
Dosage:0.5 μg/kg prime, 0.05 μg/kg/min; 2 μg/kg prime, 0.2 μg/kg/min; 4 μg/kg prime, 0.4 μg/kg/min; 8 μg/kg prime, 0.8 μg/kg/min
-
Administration:Intravenous injection; last for 30-60 min
-
Result:Significantly reduced mean blood pressure and increased mean perfusion pressure at 4 μg/kg prime, 0.4 μg/kg/min dose, while heart rate did not change.
