Abstract

<b>Background:</b> The thiazolides, typified by nitazoxanide, are an important class of anti-infective agents. A significant problem with nitazoxanide and its active circulating metabolite tizoxanide is their poor solubility. <b>Results:</b> We report the preparation and evaluation of a series of amine salts of tizoxanide and the corresponding 5-Cl thiazolide. These salts demonstrated improved aqueous solubility and absorption, as shown by physicochemical and <i>in vivo</i> measurements. They combine antiviral activity against influenza A virus with excellent cell safety indices. We also report the x-ray crystal structural data of the ethanolamine salt. <b>Conclusion:</b> The ethanol salt of thiazolide retains the activity of the parent together with an improved cell safety index, making it a good candidate for further evaluation.
