The chemical analysis of aerial parts of the melliferous Viguiera dentata led to the isolation of 20 substances, including the new cycloartanes 24‐epi‐argentatin C, 7β‐hydroxy‐24‐epi‐argentatin C, 7β‐hydroxy‐argentatin B. In‐combo results indicated that specific argentatins and ent‐kaurenoic acids have the potential to control Spodoptera frugiperda ...

Characterization of the Cubamyces Menziesii Terpenome
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Lienhwalides: Unique Tropolone–Maleidride Hybrids from Hypoxylon lienhwacheense
Lienhwalides are novel tropolone–maleidride hybrid molecules unique in nature. Absolute configuration is solved by semisynthetic approaches and X‐ray analysis. Interplay between both lwt and lwm biosynthetic gene clusters is responsible for the production of lienhwalides.

The homopolymerization of the bio‐based 2‐octyl acrylate and methacrylate is compared with their oil‐based counterparts 2‐ethylhexyl acrylate and methacrylate. Using different characterization techniques it is found that the bio‐based monomers suffer from a higher rate of chain transfer to polymer, leading to a higher degree of long chain branching (in

Clade III Synthases Add Cyclic And Linear Terpenoids To The Psilocybe Metabolome
Psilocybe “magic mushrooms” are best known for their indolethylamine psilocybin, yet they encode enzymes for a much more diverse arsenal of small and potentially bioactive molecules. Here, we report on four Psilocybe cubensis clade III sesquiterpene synthases, CubB‐CubE, whose genes are differently expressed in fruiting bodies compared to vegetative ...
