. Product Overview
Alprostadil, also known as Prostaglandin E1 (PGE1), is a high-purity synthetic bioactive prostaglandin molecule with pharmaceutical-grade specifications. Though not a traditional amino-acid peptide, it exhibits peptide-like high biological activity and precise signaling regulation, widely classified as a specialty therapeutic biomolecule. Produced via standardized synthetic processes with ≥99% HPLC purity, this stable small-molecule compound features ultra-high biological availability, consistent batch repeatability and low systemic irritation. As a potent EP receptor agonist, Alprostadil specializes in vascular dilation, microcirculation activation, smooth muscle relaxation and anti-platelet aggregation. It is extensively applied in vascular function research, peripheral circulation repair, microvascular lesion conditioning and high-end pharmaceutical raw material formulation development.

3. Mechanism of Action
Alprostadil exerts targeted vascular and tissue regulation by selectively binding to EP prostanoid receptors distributed on vascular smooth muscle, endothelial cells and peripheral tissues. It activates intracellular adenylate cyclase, elevates cAMP levels and reduces intracellular calcium concentration, triggering continuous vascular smooth muscle relaxation and systemic microvascular dilation. Meanwhile, it effectively inhibits platelet adhesion and aggregation, improves blood rheology, and eliminates microcirculation stasis and hypoxic damage.
Different from common vasodilators with transient efficacy, Alprostadil delivers dual vascular protection and metabolic optimization. It repairs damaged vascular endothelial function, improves peripheral tissue oxygen and nutrient supply, blocks inflammatory cascades caused by microcirculation disorders, and achieves long-term stabilization of vascular physiological function without endocrine disturbance or drug resistance.
4. Core Benefits & Applications
- Microcirculation Activation: Dilates peripheral microvessels, improves blood flow velocity, relieves tissue ischemia and hypoxia, and repairs microcirculation dysfunction caused by aging and vascular sub-health.
- Vascular Endothelial Repair: Protects vascular endothelial cells, reduces endothelial inflammatory damage, improves vascular elasticity, and delays peripheral vascular tissue degeneration.
- Anti-Thrombotic & Blood Regulation: Inhibits abnormal platelet aggregation, optimizes blood rheological properties, and reduces the risk of microvascular stasis and occlusion.
- Smooth Muscle Regulation: Relaxes cavernosal and peripheral smooth muscle, improves local blood perfusion, and supports physiological tissue function recovery.
- Professional Research Use: High-purity API for vascular pharmacology, microcirculation mechanism research, endothelial repair study and pharmaceutical formulation development.
