A Radical Cascade with Double Intramolecular Hydrogen Atom Transfer for the Generation of Bisfunctionalized Cyclopentanes from Linear Alkynes

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
A radical cascade process involving the activation of two aliphatic C–H bonds in a series of five elementary steps converts readily available terminal alkynes into functionalized cyclopentylmethyl arylsulfones. The methodology delivers flexible synthetic intermediates and was applied to the preparation of diquinanes and triquinanes possessing a rare ...

Heterogeneity of iridoid biosynthesis in catmints: Molecular background in a phylogenetic context

Journal of Integrative Plant Biology, EarlyView.
Evolutionary gains and losses of key biosynthetic genes likely resulting from multiple independent evolutionary events explain why certain Nepeta (catnip) species produce both the active, cat‐attracting nepetalactones and sugar‐bound iridoids, while others make only the sugar‐bound forms, and some have lost iridoid production entirely.

Complex engineering of Solanum alkaloids structural diversity in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
Summary Transient expression in Nicotiana benthamiana offers a powerful and versatile platform for rapid production of complex specialized metabolites. Steroidal glycoalkaloids (SGAs) and steroidal saponins produced by members of the Solanaceae family are known for their diverse structures and activities including antimicrobial, anticancer, antiviral ...

Biodegradation Behavior of Neat PLA Fibers Under Controlled Industrial Composting Conditions: Fiber Characterization and Physical Changes During the Composting Process

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Poly(lactic) acid (PLA) biodegradability in fiber form is relatively unexplored. This study shows that the drawing of the fibers during production affects the mechanical properties but slows down the biodegradation of the PLA. Biodegraded undrawn fibers showed peeling whereas drawn fibers showed crack formation on the surface.
