Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Identification of Novel Cyclooxygenase-1 Selective Inhibitors of Thiadiazole-Based Scaffold as Potent Anti-Inflammatory Agents with Safety Gastric and Cytotoxic Profile

Molecules, 2023
Major obstacles faced by the use of nonsteroidal anti-inflammatory drugs (NSAID) are their gastrointestinal toxicity induced by non-selective inhibition of both cyclooxygenases (COX) 1 and 2 and their cardiotoxicity associated with a certain class of COX-

Enabling Base‐Free Direct C–H Arylation of Thiophene Derivatives: Glycerol‐Derived Solvents as Active Reaction Media

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
Sustainable glycerol‐based solvents are effective reaction media for the Pd‐catalysed direct CH arylation of thiophene derivatives. Among them, glycerol‐derived ionic liquids act as noninnocent solvents, making the reaction base‐free, and the combination with Pd nanoparticles allows for multicycle process. Nonvolatile glycerol derivatives are employed
