Vasoactive Intestinal peptide CAS NO.40077-57-4

<p><strong>Vasoactive Intestinal Peptide (VIP)</strong> (CAS NO. 40077-57-4) is a synthetic 28-amino acid neuropeptide that functions as a <strong>potent vasodilator, neurotransmitter, and immunomodulator</strong>. It is widely distributed in the central and peripheral nervous systems, gastrointestinal tract, lungs, and immune cells. VIP acts primarily through two G protein-coupled receptors, <strong>VPAC1 and VPAC2…

1.MECHANISM OF ACTION

Vasodilation & Smooth Muscle Relaxation: In blood vessels and non-vascular smooth muscle (e.g., airways, GI tract), VIP activates adenylate cyclase, increasing cAMP. This relaxes smooth muscle, causing vasodilation, bronchodilation, and relaxation of the GI tract, reducing blood pressure and improving airflow.
Immunomodulation & Anti-inflammatory Action: VIP acts on immune cells (T-cells, macrophages, dendritic cells) to suppress pro-inflammatory cytokine production (e.g., TNF-α, IL-6, IL-12) and promote anti-inflammatory cytokine production (e.g., IL-10). It also inhibits T-cell proliferation and modulates immune tolerance.

2.PRODUCT INDICATIONS

This product is indicated for a wide range of research in physiology, pharmacology, and immunology. Key applications include:
  • Cardiovascular & Pulmonary Research: Studying its role as a vasodilator in hypertension and as a bronchodilator in asthma and COPD models.
  • Immunology & Autoimmunity Research: Investigating its potent anti-inflammatory and immunoregulatory effects in models of rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease (IBD), and sepsis.
  • Gastroenterology: Researching its effects on gut motility, secretion, and its potential role in irritable bowel syndrome (IBS).
  • Neuroscience: Exploring its neuroprotective, neurotrophic, and circadian rhythm-modulating functions.
  • Receptor Pharmacology: As the definitive endogenous agonist for VPAC1 and VPAC2 receptors, used to characterize receptor signaling and screen for receptor antagonists or agonists.


3.CLINICAL EFFICACY OF PRODUCT

  • Diagnostic Use: It is used in the VIPoma test to diagnose tumors that secrete VIP (VIPomas), which cause severe watery diarrhea syndrome.
  • Therapeutic Potential in Autoimmunity: Preclinical studies in models of rheumatoid arthritis, multiple sclerosis, and Crohn's disease show that VIP can suppress disease activity and inflammation, making it a promising candidate for biologic therapy.
  • Pulmonary Arterial Hypertension (PAH): Inhaled VIP has been investigated in clinical trials for PAH, showing potential to improve hemodynamics and exercise capacity, though development has faced challenges.
  • Erectile Dysfunction: VIP is a component of some compounded intracavernosal injection therapies for erectile dysfunction, used off-label in some regions.
