Description

Tungstic acid is a fairly strong acid, it catalyzes the oxidation by hydrogen peroxide of alkenes to the corresponding epoxides. Tungstic acid is widely used in the production of tungsten metal, alloys, and is used as a mordant for textiles and plastics. Tungstic acid has been reported to rapidly precipitate the quaternary ammonium cations in cholinergic nerve terminals, such as ACh or choline. Also, tungsten dietary supplementation has successfully been used to reduce xanthine oxide (XO) activity, resulting in decreased gastrointestinal (GI) mucosal damage because of lowered XO activity. Tungstic acid has been shown to effectively antagonize stress-induced gastric ulcers, possibly by decreasing motility and mass cell degranulation. Tungstic acid gel has been used as an epileptogenic agent since 1960. Epilepsy produced by this agent is characterized by good localization, short latency and limited duration. It is effective in cerebral cortex, brain stem and spinal cord.

In Vivo Use Guide
Sprague-Dawley rats were restrained at 4 degrees C for 2 h (stress). Tungstic acid in a single dose of 0.01, 0.1, 1, 10, 100 or 300 mg/kg (dissolved in distilled water) was administered intragastrically to animals 30 min prior to stress. Doses of tungstic acid of 1 mg/kg and higher significantly decreased ulcers.
