title: Nacartocin--analogue of oxytocin with enhanced natriuretic properties: natriuretic and hemodynamic characteristics.
abstract: Nacartocin, [2-p-ethylphenylalanine]deamino-6-carba-oxytocin, is almost three times more potent than oxytocin as a natriuretic agent. The natriuretic effect is mainly due to the inhibitory action of the peptide on tubular sodium resorption. Nacartocin decreased the blood pressure of anesthetized rats by the decrease of the total peripheral resistance which was greater than that observed after oxytocin administration. In conscious rats, Nacartocin caused a slight but prolonged increase of blood pressure.
