Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

Pest Management Science, Volume 82, Issue 11, Page 10551-10560, November 2026.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

Water Deficit Does Not Compromise the Resistance to Insect Herbivores in Plants Associated With Fungal Endophytes Able to Produce Bioactive Alkaloids

Plant, Cell &Environment, Volume 49, Issue 11, Page 8481-8496, November 2026.
ABSTRACT Plants growing in nature are exposed to multiple abiotic and biotic stressors that sometimes occur sequentially. We hypothesised that drought will not compromise the resistance levels to herbivores when plants are associated with Epichloë endophytes able to produce bioactive alkaloids. Lolium perenne plants without (nil) and with Epichloë LpTG‐

Medicinal Chemistry Aspects of Thiazole and Thiazolidine Derivatives as Fundamental Building Blocks to Design New NNRTIs Against HIV‐1 Reverse Transcriptase

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
HIV‐1 reverse transcriptase (HIV‐1 RT) is a polymerase enzyme and a key target in HIV‐1 therapy. The discovery of selective HIV‐1 RT inhibitors has highlighted thiazole scaffolds and their derivatives, thiazolidine‐2‐one and thiazolidine‐2,4‐dione, as promising structures for the rational design of novel non‐nucleoside reverse transcriptase inhibitors (

Structural and stereochemical diversity in prenylated indole alkaloids containing the bicyclo [2.2.2]diazaoctane ring system from marine and terrestrial fungi

Natural product reports (Print), 2018
Various fungi of the genera Aspergillus, Penicillium, and Malbranchea produce prenylated indole alkaloids possessing a bicyclo[2.2.2]diazaoctane ring system. After the discovery of distinct enantiomers of the natural alkaloids stephacidin A and notoamide

Hitting Coronaviruses Where It Hurts: Antiviral Strategies Targeting Viral Proteins

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
Viral proteins represent key vulnerabilities in human coronaviruses (HCoVs). This review outlines inhibitors targeting spike (S), main protease (Mpro), papain‐like protease (PLpro), and RNA‐dependent RNA polymerase (RdRp), mapping chemically diverse strategies that disrupt entry and replication, and provides an integrated view of current candidates ...

Soil-borne microorganisms and soil-type affect pyrrolizidine alkaloids in Jacobaea vulgaris [PDF]

, 2009
Secondary metabolites like pyrrolizidine alkaloids (PAs) play a crucial part in plant defense. We studied the effects of soil-borne microorganisms and soil-type on pyrrolizidine alkaloids in roots and shoots of Jacobaea vulgaris.
