ANP receptor pharmacology appears conserved across rat arterial beds; leaves open translation to human vascular responses or therapeutic analogs.
ANP receptors in the rat mesenteric artery and aorta share similar structural requirements for binding and vasorelaxation, with longer ANP peptides showing greater potency.
St‐Louis et al. (1988) studied this question. Atrial natriuretic peptides (ANP) was evaluated on Vasorelaxant effects and displacement binding potency. ANP receptors in the rat mesenteric artery and aorta have similar structural requirements for binding and myotropic responses, with ANP (99-126) and ANP (101-126) being the most potent.
