    • TLC plates were exposed overnight to a PhosphorImager Screen and product formation detected using a Bio-Rad Molecular Imager PhosphorImager. Enzyme activity was calculated by determining the percentage of the substrate converted to product by densitometry using Quantity One Software.

    • note
    • A preliminary assay against whole bacteria showed that none of the compounds, at highest concentrations ranging from 90 mM (compound 1) to 500 mM (compound 7), were able to restore susceptibility to the CAP polymyxin in Salmonella strain JSG435 that constitutively synthesizes a lipid A modified with aminoarabinose. The lack of effect against intact bacteria could result from insufficient activity against the target, poor permeability/retention, metabolic inactivation, or a combination of these factors.
