Substituted benzylamino-6-(trifluoromethyl)pyrimidin-4(1H)-ones: a novel class of selective human A-FABP inhibitors

The synthesis and biological evaluation of novel human A-FABP inhibitors based on the 6-(trifluoromethyl)pyrimidine-4(1H)-one scaffold is described. Two series of compounds, bearing either an amino or carbon substituent in the 2-position of the pyrimidine ring were investigated. Modification of substituents and chain length optimization led to novel compounds with low micromolar activity and good selectivity for human A-FABP.
