Description
Product Detail
. 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.

2. Basic Specifications

Product Name: Alprostadil Pharmaceutical Grade

Full Name: Prostaglandin E1 (PGE1)

CAS Number: 745-65-3

Molecular Weight: 354.48 Da

Purity: ≥99.0% (HPLC)

Appearance: White sterile lyophilized powder

Solubility: Soluble in sterile water and aqueous solvent

Core Feature: Potent microcirculation activator & vascular smooth muscle regulator

Grade Standard: Pharmaceutical raw material grade, low endotoxin, heavy metal compliant

Storage: -20°C sealed, dry and protected from light

Shelf Life: 24 months under standard storage conditions

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.

5. Advantages of 99% Pharmaceutical-Grade Alprostadil

Precise EP receptor targeting: Specific binding to prostanoid receptors, accurate vascular regulation with minimal systemic side effects

Dual dilation & repair efficacy: Combines rapid microcirculation activation and long-term endothelial repair, superior to single-effect vasodilators

Small-molecule high permeability: Ultra-low molecular weight ensures fast tissue penetration and high bioavailability

≥99% HPLC ultra-high purity, strict single impurity control, zero batch difference for synthetic prostaglandin biomolecule

Low endotoxin and ultra-low heavy metals, fully compliant with pharmaceutical raw material standards, stable activity and formulation compatibility

6. Safety & Usage Features

Alprostadil is a high-safety pharmaceutical biomolecule with reliable biological tolerance. It features mild physiological vascular regulation, no hormone interference, no cumulative toxicity and no drug dependence. Standard cyclic use safely optimizes microcirculation, repairs endothelial damage and improves tissue hypoxia status, suitable for long-term vascular sub-health conditioning and high-standard biomedical research applications.

ECHEMI Editorial Reference

Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.
