The aim of this study was to identify the chemical constituents of different leaf extracts from P. mucronatum and P. microphyllum and assess cytotoxic activity against strains from a human(More)
A series of arylamidines 3a-j was designed, synthesized and investigated for antimicrobial activity. Structures of the compounds were confirmed by IR, 1H-NMR and 13C-NMR and a 2D spectroscopic study was performed. A preliminary screening of the antimicrobial tests clearly showed that three out of ten arylamidines, viz, 3f, 3g and 3i, were effective against(More)
1,2,4-Oxadiazoles are an important class of compounds. Many of them have been found to possess biological activity. For example, some are analgesics, anti-inflammatory agents, antimicrobials, antivirals, pesticides and insecticides. Some have pronounced β-adrenoreceptor blocking activity combined with moderate α-adrenoreceptor blocking properties among(More)
