Ten novel aroyl thioureas have been synthesized by the reaction of 5-amino-1, 3, 4 thiodiazole-2-carboxylic acid with aroyl isothiocyanates, and yields of title compounds are 50.6%~70.3%. Their structure were characterized by IR, 1HNMR and elemental analysis. Preliminary biological activity tests exhibit that some target compounds have g...
