Synthesis, in vitro antibacterial and antifungal evaluations of new α-hydroxyphosphonate and new α-acetoxyphosphonate derivatives of tetrazolo [1, 5-a] quinoline

Abstract

A series of new α-hydroxyphosphonate and α-acetoxyphosphonate derivatives have been synthesized for the first time of tetrazolo [1, 5-a] quinoline derivatives. Elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data elucidated the structures of the all newly synthesized compounds. In vitro antimicrobial activities of the synthesized compounds were investigated against Gram-positive Bacillus subtilis, Gram-negative Escherichia coli and fungi Candida albicans and Aspergillus niger. Some of the tested compounds showed significant antimicrobial activity.
