The effect of structural change on the biological activity of a series of imidazothiazoles and thiazolobenzimidazoles is described. It was found that compounds with polar substituents at the 2 or 3 position of the ring system are less acutely toxic while maintaining antiinflammatoryactivity. Other structural changes, such as the incorporation of a gem-dimethyl substituent in the 6 position, increase
