Activité biologique
PAβN increases the susceptibilities of the three pump-overexpressing mutants of P. aeruginosa to levofloxacin 64-fold. PAβN also potentiates the activity of levofloxacin against strain PAM2391 containing plasmid pAGH97 with the mexXY genes and against wild-type strain PAM1020. PAβN has an effect on susceptibilities to other antibiotics that are substrates of efflux pumps. PAβN increases levels of accumulation of efflux pump substrates inside the cell. It enhances the activity of levofloxacin against clinical isolates of P. aeruginosa[1]. PAβN reduces the MICs in nine ciprofloxacin-resistant isolates, and in four of these, PAβN increases the susceptibility by twofold. Moreover, PAβN restores ciprofloxacin susceptibility in five of the ciprofloxacin-resistant isolates. In addition, clear effects of NMP on the ciprofloxacin MICs are seen for 20 of these ciprofloxacin-resistant isolates[2]. PAβN permeabilizes bacterial membranes in a concentration-dependent manner at levels below those typically used in combination studies, and this additional mode of action should be considered when using PAβN as a control for efflux studies[3].

Lon dysfunction-mediated collateral sensitivity drives effective antibiotic combination therapies against tigecycline-resistant pathogens. [Abstract]2025 Jul 22;44(7):115987. PMID: 40650911
PAβN dihydrochloride purchased from MedChemExpress. Usage Cited in: Cell Rep. 2025 Jul 22;44(7):115987. [Abstract]
Effect of efflux pump inhibitors (CCCP (10 mg/L), NMP (25 mg/L ), and PAβN dihydrochloride (25 mg/L)) on the susceptibility of evolved strains to tigecycline (n = 2). PAβN dihydrochloride lowered the MIC values and reversed the tigecycline-resistance phenotypes, suggesting a role for increased efflux pump activity in tigecycline resistance.
