Ring-whizzing in polyene-PtL2 complexes revisited

Beilstein Journal of Organic Chemistry, 2016
Ring-whizzing was investigated by hybrid DFT methods in a number of polyene–Pt(diphosphinylethane) complexes. The polyenes included cyclopropenium+, cyclobutadiene, cyclopentadienyl+, hexafluorobenzene, cycloheptatrienyl+, cyclooctatetraene ...

Programmed Polyene Cyclization Enabled by Chromophore Disruption

, 2022
A versatile polyene cyclization strategy was developed that exploits conjugated -ionyl derivatives. Photomediated disruption of the extended -system within these chromophores unveils a contra-thermodynamic polyene that engages in a Heck-type cyclization ...

Terpene Cyclase Mimicking Chlorine-Induced Polyene Cyclizations

, 2022
Nature forges a plethora of structurally divers polyenes with high efficiency and selectivity in a single cyclization step from achiral precursor. Imitating this powerful strategy has been the subject of numerous synthetic efforts.

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

, 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

A mixed community of actinomycetes produce multiple antibiotics for the fungus farming ant Acromyrmex octospinosus [PDF]

, 2010
BACKGROUND: Attine ants live in an intensely studied tripartite mutualism with the fungus Leucoagaricus gongylophorus, which provides food to the ants, and with antibiotic-producing actinomycete bacteria.

Identification and biosynthesis of a novel xanthomonadin-dialkylresorcinol-hybrid from Azoarcus sp. BH72.

PLoS ONE, 2014
A novel xanthomonadin-dialkylresorcinol hybrid named arcuflavin was identified in Azoarcus sp. BH72 by a combination of feeding experiments, HPLC-MS and MALDI-MS and gene clusters encoding the biosynthesis of this non-isoprenoid aryl-polyene containing ...
