title: Synthesis and antimicrobial activity of some 2-[p-substituted-phenyl]benzoxazol-5-yl-arylcarboxyamides.
abstract: New 2-[p-substituted-phenyl ]benzoxazol-5-yl-arylcarboxyamides derivatives have been synthesized by reacting 5-amino-2-[p-substituted-phenyl ]benzoxazoles with substituted-arylcarboxylic acid chlorides. The structures of the synthesized compounds were confirmed by IR and (1)H NMR spectral data. Antimicrobial activities of the compounds were investigated using the two-fold serial dilution technique against different Gram-positive and Gram-negative bacteria and the yeast C. albicans in comparison with standard drugs. Microbiological results indicated that the synthesized compounds possess a broad spectrum of activity, having an MIC value of 25-200 microg/mL at molar concentration values of 3.45 x 10(-5) and 5.74 x 10(-4) against the tested microorganisms.
