wide spectrum of 5-aminomethylene barbituric/ thiobarbituric acidderivatives was synthesized and evaluated for their Jack bean urease inhibitory activity. Methods: Among the synthesized compounds, 5-cyclohexylaminomethylene barbituricacid (3a) showed the most potent activity (IC50 = 25.8 µM), 4 times more potent than hydroxyurea (IC50 = 100.0 µM) and a similar activity to thiourea (IC50 = 22.0 µM), both

reaction of 1,3-disubstituted barbituric acid derivatives, 3-formylchromones and alkyl isocyanides proceed smoothly at room temperature to give the corresponding chromone-containing furopyrimidinesderivatives in good yields within 10 minutes in DMF. This three-component reaction represents a facile and efficient route to the furo[2,3-d]pyrimidine derivatives, which have become synthetic targets for many

the reaction of alkyl or arylisocyanides with barbituricacid derivatives which led to 5-[(alkyl or arylamino)methylene]barbituricacids in good yields at room temperature. The workup of reactions was very simple and the crude products were sufficiently pure to be used without further purification. This procedure provides an alternative method for the synthesis of aminomethylenebarbituric acids.
