Fudosteine CAS 13189-98-5 Pharmaceutical Grade Research Chemicals

Product description

Usage And Synthesis

Fudostein was launched in Japan as a new mucoactive agent for the treatment of bronchitis and respiratory congestion. This cysteine derivative was obtained from L-cysteine by condensation with either allylic alcohol in the presence of potassium persulfate or the corresponding bromoalcohol in the presence of a base. Fudostein was shown to significantly reduce mucus glycoprotein hypersecretion and inhibit infiltration of airway mucosa by lymphocytes and inflammatory cells in bronchitic rats. When given to bronchitic rabbits, an oral dose of 500 mg/kg daily potently decreased the fucose/ N-acetylneuraminic acid in sputa, so exhibiting mucoregulatory properties. In another study with SO2-exposed rabbits, fudostein suppressed blood flow of tracheal microvasculature increased by SO2, partly due to scavenging of superoxide anion.
