DNA gyrase inhibitor EN-7

DNA gyrase inhibitor EN-7 (EN-7) is a potent bacterial DNA gyrase inhibitor, is active against pathogenic species that are resistant to ciprofloxacin and other clinically important antibiotics.EN-7 inhibited growth of the wild-type strain (S. aureus) with MIC 1 μM.Strains containing GyrA A34T (mut-3 and mut-9), GyrA P219Q (mut-6), and GyrB K417E (mut-1, mut-2, mut-4, and mut-5) exhibited moderate resistance, with MICs of either 4 or 8 μM.EN-7 inhibited sporulation pathway in the bacterial genus Streptomyces.
