Use of Polygalacturonic acid

Polygalacturonic acid (Galacturonic acid polymer) is transparent colloid, is a major component of the cell wall. Polygalacturonic acid can be used to prepare silver nanoparticles (AgNPs), as an antioxidant and anti-inflammatory that protect cells from destructive effect of elevated ROS and accelerate wound healing. Polygalacturonic acid nanoparticles also displays anti-bacterial activity[1][2].

In Vitro	Polygalacturonic acid can be used to format a durable hydrogel, to prolong the effect of drugs. Polygalacturonic acid hydrogel/hyaluronate, conjugated Ibuprofen (HY-78131) for example, prevents epidural fibrosis, the severe scar tissue adhesion of laminectomized male adult rats, and increases the efficiency of local inflammation control and reduces the side-effect of Ibuprofen[1]. Polygalacturonic acid hydrogel/hyaluronate (PGA-HA) (2%, 200 μL; 24 h) shows low cytotoxicity on L929 fibroblasts[1]. Polygalacturonic acid (PGA) preparing (Ag-PGA/HA)-PVA nanoparticles, shows anti-bacterial activity against gram-positive bacterial strains; Bacillus Subtilis and Staphylococcus Aureus, as well as gram-negative bacterial strain; Escherichia Coli[2].
In Vivo	Polygalacturonic acid (external application; 14 d) enhances a quick healing of wound infection in albino rats[2]. Animal Model: Full thickness wound model in albino rats (60-day-old, 180 g)[2] Dosage: Ag-Polygalacturonic acid/hyaluronic acid nanoparticles Administration: Applied on dorsal muscle fascia; cleaned the wound daily with alcohol; for 14 days Result: Resulted no sign of abscess formation or hypertrophic scars both in the early phase; 5th day or in the final phase; 14th day, respectively. Showed significant wound healing from day 8 while treated with (Ag-PGA/HA)-PVA nanofiber and blank (PGA/HA)-PVA nanofiber and induced epithelization on day 14.
