1.MECHANISM OF ACTION

Atrial Natriuretic Factor (3-28) (human) is a biologically active fragment of native atrial natriuretic factor (ANF), functioning as a potent and selective agonist of natriuretic peptide receptor A (NPR-A), also known as guanylate cyclase-A. Upon binding to NPR-A expressed on vascular smooth muscle cells, cardiomyocytes, renal tubular cells, and adrenal glands, this peptide activates the receptor’s guanylate cyclase activity, triggering the intracellular synthesis of cyclic guanosine monophosphate (cGMP)—a key second messenger. The elevated cGMP levels initiate downstream signaling cascades that exert multiple physiological effects, including vasorelaxation (dilation of blood vessels to reduce peripheral resistance), natriuresis (enhanced sodium excretion via the kidneys), and diuresis (increased water excretion). Additionally, it inhibits the renin-angiotensin-aldosterone system (RAAS), a critical pathway in blood pressure regulation, and suppresses cardiac hypertrophy and fibrosis by blocking pro-hypertrophic and pro-fibrotic signaling molecules, thereby protecting cardiovascular homeostasis.

2.PRODUCT INDICATIONS

This high-purity research-grade Atrial Natriuretic Factor (3-28) (human) is specifically developed for preclinical research and pharmaceutical drug development, targeting cardiovascular, renal, and metabolic disease areas. Its key applications include investigating the mechanisms of hypertension, heart failure, and cardiac remodeling; studying renal function regulation, sodium-water homeostasis, and chronic kidney disease (CKD) progression; evaluating vascular endothelial function, atherosclerosis, and vascular smooth muscle cell proliferation; developing novel therapeutics for hypertension-related end-organ damage and metabolic syndrome; and conducting basic research on natriuretic peptide signaling pathways and NPR-A ligand-receptor interaction dynamics. It is widely used in academic laboratories and pharmaceutical R&D projects as a reliable tool reagent.

3.CLINICAL EFFICACY OF PRODUCT

In hypertensive rodent models, it effectively reduces systemic blood pressure by inducing vasorelaxation and inhibiting RAAS activation, with a rapid onset of action and good safety profile. In heart failure models, it attenuates cardiac hypertrophy and interstitial fibrosis, improves cardiac contractility and diastolic function, and reduces ventricular remodeling. For renal disease models, it enhances glomerular filtration rate (GFR), promotes sodium and water excretion, and alleviates renal interstitial fibrosis, showing potential in delaying CKD progression.
