We suggest that the use of ultrathin cryo-sectioning can be used to better visualize and understand drug interaction mechanisms on the bacterial cell membrane.]]> Wed 26 Oct 2022 11:36:12 AEDT ]]> In vitro synergistic activity of NCL195 in combination with colistin against Gram-negative bacterial pathogens https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42541 Wed 24 Aug 2022 16:53:29 AEST ]]> Molecular characterization of lipopolysaccharide binding to human α-1-acid glycoprotein https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17083 a, Rd and Re rough LPS mutants. The SAR analysis enabled by the binding data suggested that, in addition to the important role played by the lipid A and core components of LPS, it is predominately the unique species- and strain-specific carbohydrate structure of the O-antigen polysaccharide that largely determines the binding affinity for AGP. Together, these data are consistent with the role of AGP in the binding and transport of LPS in plasma during acute-phase inflammatory responses to invading Gram-negative bacteria.]]> Wed 11 Apr 2018 11:39:50 AEST ]]> Oral administration of a 2-aminopyrimidine robenidine analogue (NCL195) significantly reduces Staphylococcus aureus infection and reduces Escherichia coli infection in combination with sub-inhibitory colistin concentrations in a bioluminescent mouse model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53705 Wed 10 Jan 2024 11:03:27 AEDT ]]> The Gram-negative permeability barrier: tipping the balance of the in and the out https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54519 Tue 27 Feb 2024 15:46:23 AEDT ]]>
