A series of novel N-[2-(substitutedphenyl)-5-methyl-4-oxo-1,3-thiazolidin-3-yl]benzamides (4a-g) were synthesized and structurally confirmed by elemental analysis, IR, H NMR and MS spectral data. Further, the antiviral screening of N-[2-(substitutedphenyl)-5-methyl-4-oxo-1,3-thiazolidin-3-yl]benzamides (4a-g) against a broad panel of DNA and RNA viral strains indicated that N-[2-(4-chlorophenyl...
