AFM Study of Nanoscale Membrane Perturbation Induced by Antimicrobial Lipopeptide C₁₄ KYR

Membranes, 2021
Lipopeptides have been extensively studied as potential antimicrobial agents. In this study, we focused on the C14-KYR lipopeptide, a modified version of the KYR tripeptide with myristic acid at the N-terminus. Here, membrane perturbation of live E. coli

Ultrashort antibacterial and antifungal lipopeptides [PDF]

Proceedings of the National Academy of Sciences, 2006
Host-defense cationic antimicrobial peptides (≈12–50 aa long) play an essential protective role in the innate immune system of all organisms. Lipopeptides, however, are produced only in bacteria and fungi during cultivation, and they are composed of specific lipophilic moieties attached to anionic peptides (six to seven amino acids)

In Vitro and Ex Vivo Antibiofilm Activity of a Lipopeptide Biosurfactant Produced by the Entomopathogenic Beauveria bassiana Strain against Microsporum canis

Microorganisms, 2020
Microsporum canis is one of the most important dermatophyte causing tinea corporis and tinea capitis and its biofilm-form has a poor therapeutic response. The biosurfactant production by entomopathogenic fungi (EPF) has not been reported yet.

Genotoxicity of cationic lipopeptide nanoparticles

Toxicology Letters, 2020
The genotoxicity of cationic lipopeptide nanoparticles (cLPNPs) was evaluated in vivo and in vitro comet assay and the in vivo chromosome aberrations test. In vitro comet assay, human blood cells were exposed to cLPNPs at the concentration of 2.5, 5, 10, 20, 40 and 100 μg/mL.

The elucidation of the multimodal action of the investigational anti-Candida lipopeptide (AF4) lead from Bacillus subtilis

Frontiers in Molecular Biosciences, 2023
Background:Candida species are the main etiological agents for candidiasis, and Candida albicans are the most common infectious species. Candida species’ growing resistance to conventional therapies necessitates more research into novel antifungal agents.

ANTIMICROBIAL ACTIVITY OF LIPOPEPTIDES [PDF]

Postępy Mikrobiologii - Advancements of Microbiology, 2018
Abstract The constantly growing number of multidrug-resistant bacterial strains prompts the search for alternative treatments. Synthetic peptides based on natural antimicrobial peptides, also known as antimicrobial lipopeptides, can become a promising group of “drugs” to fight multi-resistant bacteria.
