The primary aim of this study was to incorporate biologically active pharmacophores like 1,3,4-thiadiazole and Schiff base moiety into metronidazole without modifying the nitro group. The synergy arising from the successful incorporation of imidazole ring, thiadiazole ring and Schiff’s base pharmacophore was exploited in this research. It was expected that, since these pharmacophores have individual antibacterial and anthelmintic activity, their successful incorporation in one molecule would improve the antibacterial and anthelmintic activity of the compound along with improved safety and efficacy. Some compounds (1, 1b, 1f and 1e) showed significant antibacterial activity compared to the standard. Similarly, compounds 1, 1b and 1g exhibited significant anthelmintic activity against P. excavatus and P. species.
