25, and 26 showed promising anticancer activity in all four tested cancer cell lines (HL-60, MOLT-4, PC-3, and HeLa). Compound 25 emerged as a very good potentiator of ciprofloxacin against multidrug resistant S. aureus and also showed promising anticancer activity. The present communication describes syntheses, bio-evaluation, and structure-related activity of the (E)-3-(substitutedphenyl)-1-hetrylprop-2-en-1-ones

The key precursor for the synthesis of the tittle system are an active hetero chalcones (1&2) which reacted with sulfathiazole to afford α-β-unsaturated Schiff bases represented by compounds 4-( (z)-(E)-2,3,5-tri aryl allylidene amino)-N-(thiazole-2-yl) benzene sulfonamide (3&4). The lase one was under went multicomponent witting reaction in presence of acid chloride and tri phenyl phosphine in basic media from tri ethyl amine to afford the substituted pyrrole named 4-(2,3,5-tri aryl-1H-pyrrole-1-yl)-N-(thiazole-2-yl) benzene sulfonamide (5-11).The structure of prepared compounds were determined by the available physical and spectral methods M.P. ,T.L.C , U.V , FT-IR & 1H-NMR
