A new biocidal agents fluorine substituted-3-thioxopyrimidine-5-carbonitriles (2-9) and/or the related fluorine substi- tuted pyrimido (4,5-d) pyrimidines (10-14) were synthesized by the cycloaddition of fluorinated β- arylidine malo- nonitriles (1a-c) followed by a nucleophilic attack against α,β-bifunctional reagents in different conditions. Structures of the fluorine targets were characterized by their elemental analysis and spectral data (UV, IR, ¹H NMR, ¹³C NMR and mass measurements) and further evaluated as photochemical probe for inhibition of Vitiligo, it was found that compounds 5, 9, 11 and 12 exhibited high potency over the investigated compounds.
