Effect of Post–Polyketide Synthase Modification Groups on Property and Activity of Polyene Macrolides

open access: yesAntibiotics, 2023
The biosynthesis of polyene macrolides, which are natural products produced by soil actinomycetes, have been extensively explored, and recent studies have focused on the effects of post–polyketide synthase (PKS) modifications to polyene macrolides on ...

New Glycosylated Polyene Macrolides: Refining the Ore from Genome Mining

open access: yesAntibiotics, 2022
Glycosylated polyene macrolides include effective antifungal agents, such as pimaricin, nystatin, candicidin, and amphotericin B. For the treatment of systemic mycoses, amphotericin B has been described as a gold-standard antibiotic because of its potent

Sterol Sponge Mechanism Is Conserved for Glycosylated Polyene Macrolides [PDF]

open access: yesACS Central Science, 2021
Amphotericin-like glycosylated polyene macrolides (GPMs) are a clinically and industrially important family of natural products, but the mechanisms by which they exert their extraordinary biological activities have remained unclear for more than half a century.

Polyene macrolide antifungal drugs trigger interleukin-1β secretion by activating the NLRP3 inflammasome. [PDF]

open access: yesPLoS ONE, 2011
The use of antimycotic drugs in fungal infections is based on the concept that they suppress fungal growth by a direct killing effect. However, amphotericin and nystatin have been reported to also trigger interleukin-1β (IL-1β) secretion in monocytes but

The Discovery of Actinospene, a New Polyene Macrolide with Broad Activity against Plant Fungal Pathogens and Pathogenic Yeasts

open access: yesMolecules, 2021
Phytopathogenic fungi infect crops, presenting a worldwide threat to agriculture. Polyene macrolides are one of the most effective antifungal agents applied in human therapy and crop protection. In this study, we found a cryptic polyene biosynthetic gene

Substantial improvement of tetraene macrolide production in Streptomyces diastatochromogenes by cumulative drug resistance mutations.

open access: yesPLoS ONE, 2020
Tetraene macrolides remain one of the most reliable fungicidal agents as resistance of fungal pathogens to these antibiotics is relatively rare. The modes of action and biosynthesis of polyene macrolides had been the focus of research over the past few ...

Engineered Biosynthesis of Disaccharide-Modified Polyene Macrolides [PDF]

open access: yesApplied and Environmental Microbiology, 2013
ABSTRACT Recent work has uncovered genes for two glycosyltransferases that are thought to catalyze mannosylation of mycosaminyl sugars of polyene macrolides. These two genes are nypY from Pseudonocardia sp.

Effect of Polyene Macrolides on Cholesterol Metabolism of the Chick

open access: yesExperimental Biology and Medicine, 1969
SummaryIt was shown that small concentrations of certain dietary polyene macrolides, and in particular the aromatic heptaenes, effectively reduce plasma cholesterol of cholesterolfed chicks, presumably through a mechanism which involves binding of lipids, particularly cholesterol, in the digestive tract.

The polyene macrolide antibiotics [PDF]

open access: yesPostgraduate Medical Journal, 1979
Summary The mode of action of the polyene antibiotics is reviewed together with the effect of genetic and environmental factors on sensitive organisms. The future prospects of polyenes in the treatment of systemic mycoses are considered.
