Novel heterocyclic 1,3,4-oxadiazole derivatives of fluoroquinolones as a potent antibacterial agent: Synthesis and computational molecular modeling.

Design and synthesis of novel series of 1,3,4-oxadiazoles containing FQs derivatives and screened their antibacterial, antimycobacterial properties. The synthesized compounds were characterized by different spectral techniques like IR, H NMR, C NMR, mass and elemental analysis. The results of the antimicrobial activity and compounds 6d, 6b, 6e, 6f and 6a demonstrated potent antibacterial activities with zone of inhibition of 42, 36, 37, 34 and 30 mm against S.

Design, Synthesis and Antibacterial Evaluation of Compounds Based on New Benzoxepine-oxime-1,2,3-triazole Hybrid.

Background: A library of compounds related to the new benzoxepine-oxime-1,2,3-triazole hybrid was created as probable antibacterial agents. Their synthesis involved a Cu-catalyzed azidealkyne cycloaddition (CuAAC) as a key step to construct the desired 1,2,3-triazole ring. Thus the click reaction between the appropriate alkyne containing the benzoxepine-oxime framework with aryl azides afforded the target compounds in good yields.
