Dietary Terpenoids in Advancing Biofilm‐Mediated Cancer Prevention: Antibiofilm Cascade, Molecular Crosstalk, and Nano‐Facilitated Functional Delivery

Cell Biochemistry and Function, Volume 44, Issue 8, August 2026.
ABSTRACT The role of microbes in cancer is gaining attention these days, especially in the context of tumor‐associated biofilms and dysbiotic microbiota. Biofilm‐producing microorganisms, such as Fusobacterium nucleatum and Helicobacter pylori, trigger oncogenic inflammation and immune evasion in tumor initiation and progression, and in the development

Elucidation of the myrcene ozonolysis mechanism from a Criegee Chemistry perspective [PDF]

Atmospheric Chemistry and Physics
Criegee intermediates (CIs) are highly reactive species generated during the alkene ozonolysis, which play a critical role in atmospheric chemistry. Myrcene is a typical monoterpene, and its linear structure is significantly different from other cyclic ...

Daidai Flower Essential Oil as a Multifunctional Natural Agent: Chemical Profile, Antimicrobial Activity, Preliminary Insecticidal Potential, and Improved Microbiological Quality of Fresh Arugula During Refrigerated Storage

Journal of Food Science, Volume 91, Issue 8, August 2026.
ABSTRACT This study evaluates the potential of daidai flower essential oil (DFEO) (Citrus aurantium var. daidai) as a natural preservative for fresh leafy vegetables. The chemical composition of DFEO was determined by gas chromatography coupled with mass spectrometry (GC–MS), revealing a neroli‐type profile dominated by linalool (42.8%), limonene (19.9%

Molecular evolution of terpene synthase underlying the diversification of isoprene emission in Fagaceae

Plant Biology, Volume 28, Issue 5, Page 1315-1329, August 2026.
Isoprene emission in oaks originated from convergent adaptive evolution of terpene synthases, involving a substrate shift from monoterpene to isoprene production within a Fagaceae‐specific TPS lineage. Abstract Plants emit a wide range of volatile organic compounds, among which isoprene is the most abundant and atmospherically influential. Although oak

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

Assessment of the Acute Toxicity and Anxiolytic‐Like Effect of α‐Humulene in Adult Zebrafish (Danio rerio)

Chemistry &Biodiversity, Volume 23, Issue 7, July 2026.
The monocyclic sesquiterpene α‐humulene elicited a significant anxiolytic‐like behavior in adult zebrafish and no observable acute toxicity. Pharmacological dissection suggested that this effect is independent of the benzodiazepine (BZD) binding site on the gamma‐aminobutyric acid (GABA) type A receptor (GABAAR), but it depends on the serotonin type 3 ...
