Polyene macrollide biosynthesis in streptomycetes and related bacteria: recent advances from genome sequencing and experimental studies

, 2016
The polyene macrolide group includes important antifungal drugs, to which resistance does not arise readily. Chemical and biological methods have been used in attempts to make polyene antibiotics with fewer toxic side effects.

Dehydroconicasterol and Aurantoic Acid, a Chlorinated Polyene Derivative, from the Indonesian Sponge Theonella swinhoei

, 2016
The chlorinated polyene aurantoic acid (1) and the 4-methylene sterol dehydroconicasterol (2) were isolated from the Indonesian sponge Theonella swinhoei, and their structures were elucidated by interpretation of spectroscopic data.

Kinetic studies of polyene exchange and substitution in low valent octahedral metal complexes [PDF]

, 1987
The kinetics of polyene exchange and substitution in (polyene)Cr(CO)3 complexes has been investigated. The exchange reaction involving displacement of complexed polyene for free polyene (Chapter 2) has shown two competing rate determining pathways to be ...

Exploration of the substrate promiscuity of biosynthetic tailoring enzymes as a new source of structural diversity for polyene macrolide antifungals

, 2014
Even though there is an urgent need for new antifungals with improved clinical properties, the substrate promiscuity of tailoring enzymes has been poorly studied as a source of new structural diversity for polyene macrolides. We explore the acceptance of
