Transcriptional responses of
Background Burkholderia cenocepacia is a Gram-negative opportunistic pathogen displaying high resistance to antimicrobial peptides and polymyxins. We identified mechanisms of resistance by analyzing transcriptional changes to polymyxin B treatment in ...

Synergistic Killing of Polymyxin B in Combination With the Antineoplastic Drug Mitotane Against Polymyxin-Susceptible and -Resistant Acinetobacter baumannii: A Metabolomic Study [PDF]
Polymyxins are currently used as the last-resort antibiotics against multidrug-resistant Acinetobacter baumannii. As resistance to polymyxins emerges in A. baumannii with monotherapy, combination therapy is often the only remaining treatment option.

Selective Reductive Cleavage of the Threonine 2 Peptide Bond of Penta-N-Boc-Polymyxin B with Sodium Borohydride [PDF]
Sodium borohydride surprisingly cleaves the Threonine2 (Thr2) peptide bond in N-protected Polymyxin B. Occurring at 20 ºC, the mild reductive cleavage is novel; and it facilitates the synthesis of PMB-derived antibiotics.

Polymyxin B-Induced Skin Hyperpigmentation [PDF]
Polymyxin B-induced skin hyperpigmentation is a rare adverse drug reaction (ADR). In this report, we present the case of a patient who underwent an abscess resection with right epididymitis, in which a multidrug-resistant Klebsiella pneumoniae infection (

Polymyxin B Intravenous Administration Strategy Guided by Minimum Inhibitory Concentration in Critically Ill Patients With Pulmonary Infection: Insights From PBPK Modeling. [PDF]
PBPK/PD modeling and clinical retrospective validation of intravenous polymyxin B in critically ill patients with pulmonary infection. ABSTRACT Intravenous polymyxin B (PMB) is widely used for treating drug‐resistant gram‐negative pneumonia, though its efficacy in pulmonary infections is considered limited.
