2-(N-beta-D-glucopyranosyl)aminothiazole-4-carboxylate, and ammonolysis led to the corresponding 4-carboxamide. Antimicrobial screening against five microorganisms showed that N-(2,3,5-tri-O-acetyl-beta-D-ribofuranosyl)rhodanine and the glucosylaminothiazole-4-carboxylate had the broadest spectrum of inhibitory activity, although the thioureas usually showed inhibition of some organisms.
