Bioorg Med Chem Lett. 2014 Feb 15;24(4):1236-8. doi: 10.1016/j.bmcl.2013.12.010. Epub 2013 Dec 7.

Abstract

A series of novel 1,2,4-triazolo [3,4-a] phthalazine derivatives were synthesized in five steps from a common precursor, phthalic anhydride. Most of synthesized phthalazine derivatives showed inhibitory activity against Staphylococcus aureus. One of phthalazine derivatives 5l showed inhibitory activity against all tested bacterial and fungal strains.

Keywords: Antimicrobial; Phthalazine; Synthesis; Triazole.
