  • Patent number: 10961214
    Abstract: Newly synthesized derivatives of BAS00127538 have been discovered to possess antibiotic activity and to combat resistant bacterial strains. Compounds and pharmaceutical compositions containing these compounds are described, and are based on a generic scaffold structure. Synthetic methods and methods of using the compounds also are described. Preferred compound 6jc48-1 ((E)-2,4-bis(4-bromophenyl)-6-(4-(dimethyl-amino)styryl)pyrylium boron tetrafluoride salt) binds to Lipid II with high affinity, has markedly reduced cytotoxicity than BAS00127538, and retains activity against drug-resistant strains of Enterococci. It is stable in plasma, has dramatically improved pharmacokinetic and pharmacodynamics properties, and possesses in vivo efficacy in a mouse model of sepsis.
