De novo design of lipopeptide-based fusion inhibitor as potential broad-spectrum antiviral agent

, 2023
The recent surge in emerging viral infections warrants the need to design broad-spectrum antivirals. We aimed to develop a lead molecule that targets the membrane to block fusion, an obligate step of enveloped virus infection.

The Iturin and Fengycin Families of Lipopeptides Are Key Factors in Antagonism of Bacillus subtilis Toward Podosphaera fusca [PDF]

, 2007
Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress the disease on melon in detached leaf and seedling assays, were ...

Lipopeptide Pepducins as Therapeutic Agents

, 2021
Pepducins are lipidated peptides that target the intracellular loops of G protein-coupled receptors (GPCRs) in order to modulate transmembrane signaling to internally located effectors. With a wide array of potential activities ranging from partial, biased, or full agonism to antagonism, pepducins represent a versatile class of compounds that can be ...

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)

Self-Assembly of a Catalytically Active Lipopeptide and Its Incorporation into Cubosomes [PDF]

, 2019
The self-assembly and biocatalytic activity of the proline-functionalized lipopeptide PRW-NH-C16 are examined and compared to that of the related PRW–O-C16 lipopeptide, which differs in having an ester linker between the lipid chain and tripeptide ...
