Pyridyl‐Imidazopyridine Derivatives Displaying Submicromolar Activity Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Previously reported pyridyl‐thiazoles and highly active imidazopyridines against Trypanosoma cruzi inspired the design of a new series of pyridyl‐substituted imidazopyridines. Among the synthesized compounds, 5h emerged as the most promising derivative, displaying potent trypanocidal activity (EC50 = 0.16 μM), excellent selectivity (SI > 1250), and ...

Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, Volume 82, Issue 7, Page 6808-6816, July 2026.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.
