Unified short syntheses of oxygenated tricyclic aromatic diterpenes by radical cyclization with a photoredox catalyst

open access: yesCommunications Chemistry, 2023
The biomimetic two-phase strategy employing polyene cyclization and subsequent oxidation/substitution is an effective approach for divergent syntheses of [6-6-6]-tricyclic diterpenes.

Epoxy Clerodane Diterpene Attenuates the Differentiated Adipocyte Hypertrophy and Enhances Mitochondrial Metabolism. [PDF]

open access: yesChemistryOpen
Epoxy Clerodane Diterpene (ECD) significantly reduces adipocyte hypertrophy and lipid accumulation in human mesenchymal stem cell (hMSC)‐derived adipocytes. ECD improves mitochondrial membrane potential (ΔΨm), increases thermogenic regulators (UCP‐1, PPARγC1α), decreases adipogenic markers (C/EBPα, PPARγ), and reduces inflammatory mediators (TNF‐α, NF ...

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Effect of Diterpenes Isolated of the Marine Alga Canistrocarpus cervicornis against Some Toxic Effects of the Venom of the Bothrops jararaca Snake

open access: yesMolecules, 2015
Snake venoms are composed of a complex mixture of active proteins and peptides which induce a wide range of toxic effects. Envenomation by Bothrops jararaca venom results in hemorrhage, edema, pain, tissue necrosis and hemolysis. In this work, the effect

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

open access: yesPolymer 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.
