A series of 2-(p-substitutedphenyl/benzyl)-5-[3-[4-[(p-chlorophenyl)/phenyl]piperazin-1-yl]propionamido]-benzoxazoles (3-22) have been synthesized towards discovering new antimicrobial compounds in order to fight against pathogens, which have become resistant to antibiotics and are the cause of increased mortality and morbidity throughout the world. Structures of new derivatives have been elucidated by spectral techniques. New and previously synthesized benzoxazoles have been evaluated for their antibacterial and antifungal activity against standard strains, and their drug-resistant isolates in comparison with reference drugs. This study is aimed to investigate the efficacy of the antimicrobial effect of different amido bridges on the same homologue structures of benzoxazole compounds. Compounds 3-22 exhibit broad antibacterial activity with MIC (Minimum Inhibitory Concentration) values of 128-256 μg/mL against Staphylococcus aureus and its isolate except for derivative 7 that has a MIC value of 32 μg/mL against S. aureus isolate and compounds 3 and 22 which have MIC value of 512 μg/mL against S. aureus. Also, the tested compounds 3-22 possess low antifungal activity with MIC values of 128 μg/mL against Candida albicans in comparison with antifungal reference drugs, fluconazole and amphotericin B.

Some new 2-(benzyl/p-chlorobenzyl)-5-[(substituted-thienyl/phenyl/phenylthiomethyl/benzyl)carbonylamino]benzoxazole derivatives have been synthesized by reacting 5-amino-2-(benzyl/p-chlorobenzyl)benzoxazoles with appropriate carboxylic acid chlorides. The structures of the synthesized compounds were confirmed by IR, 1H NMR and MASS spectral data. In vitro antimicrobial activities of the compounds were investigated using twofold serial dilution technique against different two Gram-positive, two Gram-negative bacteria and three Candida spp. in comparison with standard drugs. Microbiological results indicated that the newly synthesized 2-(benzyl/p-chlorobenzyl)-5-[(substituted-thienyl/phenyl/phenylthiomethyl/benzyl)carbonylamino]benzoxazole derivatives (3-12) possessed a broad spectrum of activity having MIC values of 6.25-100 μg/ml against the tested microorganisms. Especially, with an MIC value of 6.25 μg/ml, 2-(p-chlorophenyl)-5-[(2,5-dimethylphenyl)carbonylamino]benzoxazole 4 displayed the same activity against Candida albicans as the standard drug clotrimazole.

A series of 23 new 2-[p-substituted-benzyl]-5-[p-substituted-phenyl/benzyl- carbonylamino]benzoxazole derivatives has been synthesized by reacting 5-amino-2-[p-substituted-benzyl]benzoxazoles with the appropriate carboxylic acid chlorides. The structures of the synthesized compounds were confirmed by IR and 1H-NMR spectral data. Antimicrobial activities of the compounds were investigated using the twofold serial dilution technique against two gram-positive and two gram-negative bacteria and three Candida species in comparison with standard drugs. Microbiological results indicated that the newly synthesized 2-[p-substituted-benzyl]-5-[p-substituted-phenyl/benzyl- carbonylamino]benzoxazole derivatives (3-25) possessed a broad spectrum of activity, showing MIC values of 6.25-200 μg/mL against the gram-positive and gram-negative microorganisms tested. Moreover, they showed significant antifungal activity with MIC values of 3.12-100 μg/mL against the Candida species tested. Especially, with a MIC value of 3.12 μg/mL, 2-benzyl-5-[p-bromobenzyl-carbonylamino]benzoxazole 9 displayed the same activity against C. glabrata as the standard drug myconazol.
