Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

Agricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Rh(III)‐Catalyzed [4 + 3] Annulation for Construction of Heterocycle‐Fused Azepines

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Rhodium(III)‐catalyzed [4 + 3] annulation of 2‐arylquinazolinones with allyl ethers enables the facile synthesis of heterocycle‐fused azepines. This step‐economical protocol proceeds via CH and NH functionalization, accommodating diverse heteroatom‐ and polyaromatic‐substituted substrates to deliver structurally varied fused azepines efficiently and ...

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.

Tailored RuNi heterobimetallic complexes as dual catalysts for ROMP of norbornene and ethylene oligomerization

Results in Chemistry
A series of four novel RuL-NiL heterobimetallic complexes was synthesized via the in-situ condensation of primary amine Ru precursors with salicylaldehyde or 3-tert-butylsalicylaldehyde, generating an N,O-chelated iminic bridge that links the two metal ...

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 935-942, July 2026.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...
