  • 产品描述
    SPR741, formerly NAB741 (12), is a cationic peptide derived from polymyxin B and is one such potentiator molecule that is under development for the treatment of serious Gram-negative bacterial infections.
  • 体外实验
    SPR741 potentiates antibiotics that are substrates of the AcrAB-TolC efflux pump in E. coli, effectively circumventing the contribution of this pump to intrinsic antibiotic resistance. The intrinsic resistance of E. coli to certain antibiotics that is mediated by both the outer membrane and the AcrAB-TolC efflux system can be overcome, or circumvented, by combining the antibiotic with SPR741 but that potentiation of intrinsic resistance due primarily to efflux may be limited.SPR741 lacks significant antibacterial activity as a stand-alone agent but interacts with the outer membrane of Gram-negative bacteria to increase permeability and thereby improve the accumulation of coadministered antibiotics inside the pathogen.
  • 体内实验
    SPR741 has the ability to permeabilize the outer membrane of Gram-negative bacteria, thus sensitizing them to hydrophobic antibiotics. SPR741 has a significantly safety profile of compared to that of polymyxin B, which suffers severe, dose-limiting nephrotoxicity in humans. In multiday rodent and nonhuman primate studies, polymyxin B exhibited nephrotoxicity at a far-lower exposure-normalized dose than SPR741.
