Reaction Conditions

Reaction Steps

Acetic anhydride (34 ml) was added to a solution of malonic acid (20 g) and methylurea (12.5 g) in acetic acid (46 ml). The mixture was heated to 95° C. for 3 hours then cooled to room temperature. The resulting solution was concentrated under reduced pressure and the residue as 20 mM stock solutions in dimethyl sulphoxide (DMSO, Sigma #D-5879) and serial dilutions were prepared from these solutions using DMSO, 2 μL of which were added to the wells. Activity at room temperature was measured by monitoring the increase in fluorescence using a TECAN Ultra platereader with 340 nm excitation and 465 nm emission filters. The compounds provided have measured IC50 of less then 400 μM
