Importent alternatives: Elansolid A is an antibiotic secreted by Chitinophaga sancti. We synthesized a library of derivatives from the natural precursor elansolid C1 that was obtained by fermentation with anthranilic acid. The new compounds were tested for inhibitory activity against Staphylococcus aureus and Micrococcus luteus. None was as potent as the natural antibiotic, but stability was significantly

Synthesis and evaluation of new quinazolin-4(3H)-one derivatives as potent antibacterial agents against multidrug resistant Staphylococcus aureus and Mycobacterium tuberculosis
demonstrated equipotent MIC against multiple drug-resistant strains of S. aureus including VRSA, concentration dependent bactericidal activity against S. aureus and synergized with FDA approved drugs. Moreover, compound 4′c exhibited more potent activity in reducing the biofilm and exhibited a PAE of ∼2h at 10X MIC which is comparable to levofloxacin and vancomycin. In vivo efficacy of 4'c in murine neutropenic
