title: Heterocyclic system containing bridgehead nitrogen atom: synthesis and pharmacological activities of some substituted 1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles.
abstract: Several 3,6-disubstituted-1,2,4-triazolo[3,4-b]-1,3,4-thiadizoles were prepared by the condensation of 4-amino-3-aryl/aralkyl substituted-5-mercapto-1,2,4-triazoles 3(a-c) with various substituted aromatic/hetero aromatic acids through a single step reaction. Elemental analysis, IR, 1H NMR and mass spectral data confirmed the structure of the newly synthesized compounds. Synthesized triazolo thiadiazoles investigated for their antibacterial, antifungal, anti-inflammatory and analgesic activities. Some of the tested compounds showed moderate antimicrobial activity against various tested bacterial and fungal strains. None of the synthesized compounds have significant anti-inflammatory and analgesic activities.
