ANP (Atrial Natriuretic Peptide) vs PE-22-28
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
ANP (Atrial Natriuretic Peptide)
ANP is a cardiac hormone released by atrial myocytes in response to stretch. It promotes natriuresis, diuresis, and vasodilation, playing key roles in blood pressure and fluid regulation.
Full details →PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.

| Aspect | ANP (Atrial Natriuretic Peptide) | PE-22-28 |
|---|---|---|
| Mechanism | Binds to natriuretic peptide receptors (NPR-A) to activate guanylyl cyclase, producing cGMP. This leads to vasodilation, increased kidney filtration, and inhibition of the renin-angiotensin-aldosterone system. | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. |
| Typical Dosage | Clinical use: Carperitide (recombinant ANP) used in Japan for acute heart failure at 0.1mcg/kg/min IV infusion. | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. |
| Administration | Intravenous infusion only for clinical applications. Short half-life (~2 minutes) requires continuous administration. | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. |
| Side Effects | Hypotension (dose-limiting), headache, nausea, and potential arrhythmias at high doses. | Very limited human data. Primarily studied in animal models for safety and efficacy. |
