The reaction of 5 -(1-adamantyl)-1, 3,4-oxadiazoline-2-thione 2 with iodoethane, 2-dimethylaminoethyl chloride hydrochloride or 2-piperidinoethyl chloride hydrochloride in ethanolic potassium hydroxide yielded the corresponding 5-(1-adamantyl)-2-ethyl or substituted ethylthio-1,3,4-oxadiazoles 3a-c. Interaction of 2 with formaldehyde solution and primary aromatic amines or 1-substituted piperazines, in ethanol at room temperature yielded the corresponding 5-(1-adamantyl)-3-arylaminomethyl-1,3,4-oxadiazoline-2-thiones 4a-m or 5-(1-adamantyl)-3-(4-substituted-1-piperazinylmethyl)-1,3,4-oxadiazoline-2-thioties 5a-h, respectively. All the synthesized compounds were tested for in vitro activities against certain strains of Gram-positive and Gram-negative bacteria and the yeast-like pathogenic fungus Candida albicans. Compounds 2, 5a, and 5e were found as the most active derivatives, particularly against the Gram-positive bacteria. In addition, the antiviral activity of compounds 2, 4a-m, and 5a-h against HIV-1 using the XTT assay was carried out. Compound 2 produced 100%, 43%, and 37% reduction of viral replication at 50, 10, and 2 mug/mL concentrations, respectively. (C) 2004 Elsevier Ltd. All rights reserved.
