A series of novel N-4-(substituted)-1,3-thiazol-2-yl-2-(substituted) acetamide (9a-m) and methyl 2-(2-(2-(substituted)acetamido)thiazol-4-yl)acetate (9n-o) derivatives have been synthesized and compounds were characterised by spectral and analytical studies. All compounds were screened for their in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia by disc diffusion method and for antifungal activity against Penicillium marneffei, Trichophyton mentagrophytes, Aspergillus flavus and Aspergillus fumigatus by serial plate dilution method. Compounds 9b, 9e, 9m and 9o exhibited growth inhibition against all the tested bacterial strains, with MIC values varying from 12.5 to 6.25 μg/ml. Among the compounds tested for antifungal activity, 9a, 9b, 9d, 9j, 9k, 9p and 9n showed wide range of activity against all the tested strains. Most of the newly synthesized compounds were effective against fungal strains rather than bacterial strains. However, some of the compounds like 9a, 9e, 9j, 9k and 9i showed selective sensitivity against some of the bacterial strains whereas they were unable to sustain the growth of other strains.
