Some more new bioactive fluorine heterocyclic systems containing sulfur and nitrogen as five-membered rings: pyrazoline, imidazole, imidazolopyrimidine, thiazolidinone and 1,2,4-triazole derivatives (3-13) have been synthetically derived from the interaction of sulfa drugs with fluorine aromatic aldehyde and/or hexa fluoroacetic anhydride followed by heterocyclization reactions. Former structures of the targets have been deduced upon the help of elemental and spectral data.. Compounds 7a-f, 10c and 13 could be used as photochemical probe agents for inhibition of Vitiligo diseases, in compare with Nystatin and Nalidixic acid.
