Journal ArticleDOI
Dilipid Ultrashort Tetrabasic Peptidomimetics Potentiate Novobiocin and Rifampicin Against Multidrug-Resistant Gram-Negative Bacteria
TL;DR: Results indicate that polybasic peptidomimetic-based adjuvants repurpose novobiocin and rifampicin as potent agents against priority MDR Gram-negative pathogens.
Journal ArticleDOI
Effects of Lysine N-ζ-Methylation in Ultrashort Tetrabasic Lipopeptides (UTBLPs) on the Potentiation of Rifampicin, Novobiocin, and Niclosamide in Gram-Negative Bacteria
TL;DR: This study elucidated crucial structure–activity relationships for the optimization of polybasic antibiotic potentiators in GNB by reducing or abolishing the potentiating effects of UTBLPs with rifampicin, novobiocin, and niclosamide against GNB.
Journal ArticleDOI
Guanidinylated Polymyxins as Outer Membrane Permeabilizers Capable of Potentiating Rifampicin, Erythromycin, Ceftazidime and Aztreonam against Gram-Negative Bacteria
TL;DR: The conversion of polymyxins to guanidinylated derivatives, whereby the L-γ-diaminobutyric acid (Dab) amines are substituted with Guanidines, exhibited reduced antibacterial activity but preserved OM permeabilizing properties that allowed potentiation of several antibiotic classes.
Journal ArticleDOI
Chimeric Tobramycin-Based Adjuvant TOB-TOB-CIP Potentiates Fluoroquinolone and β-Lactam Antibiotics against Multidrug-Resistant Pseudomonas aeruginosa.
TL;DR: In this article , the authors extended the concept of tobramycin-based hybrid adjuvants to a multi-drug-resistant Gram-negative bacteria including Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa for which limited treatment options exist.
Journal ArticleDOI
Amphiphilic tribasic galactosamines potentiate rifampicin in Gram-negative bacteria at low Mg++/Ca++concentrations.
TL;DR: In this paper , the synthesis and biological properties of amphiphilic tribasic galactosamines as potential rifampicin (RIF) potentiators were reported. But the results were limited to Gram-negative bacteria and not to Pseudomonas aeruginosa.
