Six new 5-(1-/2-naphthyloxymethyl)-1,3,4-oxadiazole-2(3H)-thione, 2-amino-5-(1-/2-naphthyloxymethyl)-1,3,4-oxadiazole, 5-(1-/ 2-naphthyloxymethyl)-1,3,4-oxadiazole-2(3H)-one derivatives have been synthesized from 1-and/or 2-naphthol. The structures,of the compounds were confirmed by IR and H-1 NMR spectral data and microanalysis. The antimicrobial properties of the compounds were investigated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, Candida albicans, C. krusei and C. parapsilosis using microbroth dilution method. 2-Amino-5-(2-naphthytoxymethyl)-1,3,4-oxadiazole and 5-(2-naphthyloxymethyl)-1,3,4-oxadiazole-2(3H)-one show significantly (32 mug/ml), compounds 5-(1-/2-naphthyloxymethyl)-1,3,4-oxadiazole-2(3H)-thione, 2-amino-5-(1-naphthyloxymethyl)-1,3,4-oxadiazole and 5-(1-naphthyloxymethyl)-1,3,4-oxadiazole-2(3H)-one moderately (64 mug/ml) active against C. krusei. All the compounds were active against S. a ureus,. coli, P. aeruginosa, C. albicans, and C. parapsilosis at 64-256 mug/ml concentration. (C) 2002 Editions scientifiques et medicales Elsevier SAS.
