ANP (1-11), rat

ANP (1-11), rat is a synthetic peptide fragment corresponding to the N-terminal 11 amino acids of rat Atrial Natriuretic Peptide (ANP). This sequence represents the region of the ANP prohormone that is distinct from the mature, active 28-amino acid C-terminal hormone. The N-terminal fragment, including ANP (1-11), is co-secreted with mature ANP and serves as a biomarker and a potential bioactive peptide with its own physiological effects, distinct from the natriuretic and vasodilatory actions of ANP (99-126). It is a research tool for studying the complex processing and functions of the natriuretic peptide system in rodent models.

1.MECHANISM OF ACTION

The mechanism of action for the N-terminal ANP fragment (1-11) is different and less defined than that of the mature ANP, which acts through the NPR-A receptor. Proposed mechanisms for N-terminal fragments like ANP (1-11) include:

Interaction with Specific Receptors/Clearance Receptors: It may bind to the Natriuretic Peptide Clearance Receptor (NPR-C) with potentially higher affinity than mature ANP. NPR-C is involved in peptide clearance but can also initiate G protein-mediated signaling pathways (e.g., inhibition of adenylate cyclase via Gi), leading to biological effects.
Modulation of NPR-A Activity: Some N-terminal fragments may modulate the activity or binding of mature ANP to its primary receptor, NPR-A.
Distinct Biological Effects: Research suggests that N-terminal ANP fragments, including proANP (1-30) and smaller sequences, may have effects on:
- Renal function (modulating sodium and water excretion differently than ANP).
- Vascular tone (potentially vasoconstrictive in some contexts, opposing mature ANP).

2.PRODUCT INDICATIONS

This product is indicated for specialized research in cardiovascular and renal endocrinology, focusing on the less-characterized roles of natriuretic peptide precursors. Key applications include:

Natriuretic Peptide System Research: Studying the biosynthesis, processing, and differential biological activity of ANP and its prohormone fragments in rat models.
Biomarker Studies: Investigating N-terminal proANP (NT-proANP) as a stable biomarker for cardiac stress and heart failure. ANP (1-11) can serve as a fragment for assay development or as a research analog.
Functional Characterization: Exploring the potential physiological or pathophysiological roles of N-terminal ANP fragments in blood pressure regulation, renal hemodynamics, and vascular remodeling.
Receptor Pharmacology: As a ligand in binding studies to characterize interactions with NPR-C and other potential binding sites distinct from NPR-A.
Comparative Physiology: Comparing the effects of mature ANP versus its N-terminal fragments in isolated tissue or animal experiments.

3.CLINICAL EFFICACY OF PRODUCT

ANP (1-11), rat is a research probe, not a therapeutic. Its "efficacy" lies in its utility for elucidating fundamental biology with potential diagnostic and therapeutic implications.

Biomarker Validation: Research on N-terminal ANP fragments in animals has been instrumental in validating NT-proANP as a clinically useful, stable biomarker. In human medicine, mid-regional proANP (MR-proANP) is now a well-established blood test for the diagnosis and prognosis of acute heart failure, often outperforming BNP in certain scenarios. Rodent studies using fragments like ANP (1-11) helped establish this concept.
Uncovering Novel Biology: Studies using this fragment contribute to the understanding that the ANP prohormone encodes multiple bioactive peptides with potentially opposing or modulatory functions, painting a more complex picture of natriuretic peptide physiology.
Therapeutic Target Potential: Understanding the distinct receptors and signaling pathways activated by N-terminal fragments could reveal new targets for cardiovascular drug development, such as selective NPR-C modulators.
