 Polaprezinc Biological Activity

Description Polaprezinc is an orally bioavailable chelate composed of zinc and L-carnosine, with potential gastroprotective, anti-oxidant, anti-ulcer and anti-inflammatory activities.
Related Catalog
In Vivo Polaprezinc (PZ) is an antiulcer drug and a chelating compound consisting of a zinc ion, L-carnosine, a β-alanine dipeptide and L-histidine. Polaprezinc exerts antioxidant effects and scavenges free radicals. The efficacy of Polaprezinc is reported for acute radiation proctitis in an animal model and demonstrates that Polaprezinc has an anti-inflammatory effect following exposure to radiation[1].
Animal Admin Mice[1] Male C57BL/6J mice (8-weeks-old; weight, ~20 g) are used. The mice are acclimated for 7 days. They are housed 4-5/cage and fed a laboratory rodent pellet formula and tap water ad libitum. Mice are maintained at a constant temperature of 22°C±0.5°C, a humidity of 50%±5% and are exposed to 12 h light/dark cycles. The mice orally receive 100 mg/kg body weight Polaprezinc in the drinking water. The mice are irradiated at a dose rate of ~200 cGy/min using a 150 kVp X-ray unit. For dosimetry, a probe connected to an electrometer system is placed close to the target site.
