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,

Synthesis and Evaluation of Antimicrobial Activity of 1, 3, 4-Thiadiazole Analogues for Potential Scaffold

Journal of Pharmacopuncture, 2021
Pathogenic microbes are causal agents for various types of severe and even lethal infectious diseases. Despite of development in medication, bacterial and fungal infections still persist to be a vital problem in health care. Bacteria and several fungal species have shown resistance to antibiotics used in treatment to current medications.

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
