Influence of crosslinker on the properties of terpene‐based poly(high internal phase emulsion)s

Polymer International, EarlyView.
Myrcene was polymerized and crosslinked with hydrophilic monomeric and oligomeric dimethacrylates within high internal phase emulsions to produce hierarchically porous bio‐based poly(high internal phase emulsion)s with tuned morphology and mechanical properties.

A single residue change leads to a hydroxylated product from the class II diterpene cyclization catalyzed by abietadiene synthase [PDF]

, 2012
Class II diterpene cyclases catalyze bicyclization of geranylgeranyl diphosphate. While this reaction typically is terminated via methyl deprotonation to yield copalyl diphosphate, in rare cases hydroxylated bicycles are produced instead.

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

PLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Diterpenes from Sideritis argyrea

Fitoterapia, 2001
The known ent-kaurene diterpenes 1-9 and a new ent-labdane, ent-6beta,8alpha-dihydroxylabda-13(16),14-diene (10), were isolated from the whole plant of Sideritis argyrea. Their structures were elucidated based on one- and two-dimensional NMR techniques and HRMS.

Accidental plant poisonings in France: Lessons from a decade of national toxicovigilance

PLANTS, PEOPLE, PLANET, EarlyView.
Accidental plant poisonings reveal how modern societies are losing everyday botanical knowledge once central to food and health safety. By analyzing a decade of French toxicovigilance data, this study shows that most severe cases arise from plant misidentification or misguided self‐medication.

Bioactive Natural Products in Cardiovascular Disease: Focus on Thrombotic Events

Phytotherapy Research, EarlyView.
An overview of the role of natural products (NP) in cardiovascular disease prevention, highlighting key mechanisms of action: including antiplatelet, antithrombotic, anti‐inflammatory, and antioxidant effects. Additionally, it illustrates the integration of diet–drug interactions, nutritional epigenetics, and the role of artificial intelligence in ...
