Description:

WARNING: This product is for research use only, not for human or veterinary use.

Polaprezinc is an orally bioavailable chelate composed of zinc and L-carnosine, with potential gastroprotective, anti-oxidant, anti-ulcer and anti-inflammatory activities. Upon administration, polaprezinc increases the expression of various anti-oxidant enzymes, such as superoxide dismutase 1 (SOD-1), SOD-2, heme oxygenase-1 (HO-1), glutathione S-transferase (GST), glutathione peroxidase (GSH-px), peroxidredoxin-1 (PRDX1; PRXI) and PRXD5 (PRXV) in the gastric mucosa, which protect cells against reactive oxygen species (ROS).

Product Data
Biological target:
Polaprezinc is an orally bioavailable chelate composed of zinc and L-carnosine, with potential gastroprotective, anti-oxidant, anti-ulcer and anti-inflammatory activities.
In vitro activity:
Proliferation and colony formation assays were performed to determine the inhibitory effects of polaprezinc on the growth of LX‑2 and hepG2 cells. The proliferation assay indicated that polaprezinc may inhibit the LX‑2 cell proliferation and the migration assays confirmed the inhibition of mobility. The expression levels of fibrotic markers such as collagen I, fibronectin and α‑smooth muscle actin were downregulated following polaprezinc treatment. The proliferation activity of polaprezinc‑treated hepG2 cells was reduced and the gene chip assay indicated that series of gene expression changes associated with cancer migration, cell skeletal organization and proliferation had occurred.

In vivo activity:
The purpose of the present study was to assess the radioprotective effects of PZ (polaprezinc) in the normal intestine of C57BL/6J mice. The mice that received PZ prior to irradiation demonstrated a stronger protective effect on the normal intestine compared with those that received PZ after irradiation. The present study therefore administrated PZ 2 h before irradiation in the subsequent experiments. The mice receiving PZ developed fewer apoptotic cells in the duodenum, jejunum and ileum.
