atrial natriuretic factor

Atrial natriuretic factor (1-28) from both human and porcine sources is a potent suppressor of pro-opiomelanocortin (POMC) mRNA, exerting only a modest inhibitory effect on βEP-LI release.

Atrial Natriuretic Peptide (ANP) (1-28), rat (TFA), is the primary circulating form of ANP in rats and significantly inhibits Ang II-stimulated secretion of endothelin-1.

Atrial Natriuretic Peptide (1-28), rat is the major circulating form of ANP in rats.

ANP (1-11), rat acetate (Atrial natriuretic factor (1-11) acetate) is one of the atrial natriuretic factors, inhibitors of CRF-stimulated ACTH secretion.

Prepro-Atrial Natriuretic Factor (26-55) (human) is a polypeptide that increases cyclic GMP levels in the renal cortex and medulla, and enhances renal guanylate cyclase activity [1].

Atrial natriuretic factor (1-28) (human, porcine) TFA exhibits antihypertensive activity by promoting sodium and urine excretion. It inhibits the release of adrenocorticotropic hormone (ACTH) and β-endorphin by suppressing pro-opiomelanocortin (POMC) expression. Additionally, it elevates cGMP levels in RMIC cells, with an IC50 of 1.2 nM.

Formycin triphosphate is a fluorescent analog of ATP, exhibiting enhanced fluorescence when binding to enzyme active sites. It acts as a competitive inhibitor of avian liver pyruvate carboxylase (pyruvate carboxylase). Additionally, formycin triphosphate increases atrial natriuretic factor (ANF)-stimulated guanylate cyclase activity with an EC50 of approximately 90 μM and inhibits ATP-stimulated guanylate cyclase activity with an IC50 of around 100 μM.

Prepro-ANF (56-92), human, a precursor to the human atrial natriuretic factor, activates guanylate cyclase by specifically enhancing particulate guanylate cyclase activity within the renal membrane and unit [1].

Auriculin A, a synthetic atrial natriuretic factor (ANF), exhibits hemodynamic properties by antagonizing renal vasoconstriction in dogs and affects arterial baroreflex regulation of heart rate, systemic blood pressure, and constant flow-perfused hind limb perfusion pressure in rabbits [1] [2].

Anantin, a natriuretic peptide receptor A antagonist, binds competitively to the atrial natriuretic factor (ANF) receptor from the bovine adrenal cortex (K d = 0.6 μM) [1] [2].

Anaritide, a synthetic form of atrial natriuretic peptide (ANP) composed of 25 amino acids, enhances the glomerular filtration rate by dilating afferent arterioles and constricting efferent arterioles. It is utilized for studying its effects on patients with acute tubular necrosis, with a focus on improving dialysis-free survival rates.
