Evolutionary Reprogramming of Acyltransferase Domains in Polyene Macrolide Pathways [PDF]

Microorganisms
The evolution of type I polyketide synthase (T1PKS) assembly lines remains poorly understood. Through systematic mining of polyene biosynthetic gene clusters, we identified a novel eurocidin biosynthetic pathway capable of producing identical compounds ...

Polyene-Based Derivatives with Antifungal Activities

Pharmaceutics
Polyenes are a class of organic compounds well known for their potent antifungal properties. They are effective due to their ability to target and disrupt fungal cell membranes by binding to ergosterol and forming pores.

Polyene-Producing Streptomyces spp. From the Fungus-Growing Termite Macrotermes barneyi Exhibit High Inhibitory Activity Against the Antagonistic Fungus Xylaria

Frontiers in Microbiology, 2021
Fungus-growing termites are engaged in a tripartite mutualism with intestinal microbes and a monocultivar (Termitomyces sp.) in the fungus garden. The termites are often plagued by entomopathogen (Metarhizium anisopliae) and fungus garden is always ...

Amphotericin B and Other Polyenes—Discovery, Clinical Use, Mode of Action and Drug Resistance

Journal of Fungi, 2020
Although polyenes were the first broad spectrum antifungal drugs on the market, after 70 years they are still the gold standard to treat a variety of fungal infections. Polyenes such as amphotericin B have a controversial image.

An Improved and Practical Method for Synthesizing of α-Sanshools and Spilanthol

Frontiers in Chemistry, 2020
An efficient and practical route for the synthesis of α-sanshools and spilanthol is described herein. Several modifications of an existing method enabled the preparation of the (2E,6Z,8E,10E)-tetraene precursor of hydroxy-α-sanshool in good yield.
