Some new chalcones, 2-(4'-chlorophenylamino)-4-(4'-flurophenylamino)-6-[4'-3{3-(substituted phenyl/2-thienyl/2furanyl)-2""-propenon-1""-yl} phenylamino]-s-triazine (6a-e) have been acheived by the reaction between 2-(4'-chlorophenylamino)-4-(4'-flurophenylamino)-6-(4'-acetylphenylamino)-s-triazine (5) and differentt aromatic and heterocycli aldehydes, which on cyclisation with phenyl hydrazine hydrochloride in the presence of alkali give phenyl pyrazolines (7a-e). Chalcones (6a-e) on cyclisation with malononitrile in the presence of ammonium acetate give cyanopyridines (8a-e). The characterization of newly synthesized compounds has been done on the basis of IR, ¹H NMR spectral data as well as elemental analysis. The compounds have been evaluated for antibacterial activity against E. coli (MTCC 443), S. paratyphi-B (MTCC 733), S. aureus (MTCC 96) and B. Subtilis (MTCC 441)"
