Small molecules as arthropod kinin receptor antagonists, feeding modulators, or novel mosquitocidal agents

Pest Management Science, Volume 82, Issue 7, Page 6842-6863, July 2026.
A two‐pronged screen of small molecules – (1) on recombinant kinin receptor and (2) through topical application – identifies kinin receptor antagonists, feeding behavior modulators, and new mosquitocidal molecules. Abstract BACKGROUND Aedes aegypti and Culex quinquefasciatus mosquitoes are primary vectors for numerous human and animal pathogens and ...

Combined Effects of Arsenic and Cadmium With Selenium on Oxidative Stress Indicators in Goldfish: Implications for Veterinary Toxicology

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Co‐exposure to arsenic and cadmium alters metal accumulation and oxidative stress in goldfish. Selenium reduces arsenic bioaccumulation and lipid peroxidation while enhancing antioxidant defences. Findings highlight metal‐specific interactions, with selenium offering partial protection, emphasizing ecological risks and the importance of monitoring ...

Note on LC50 of BHC on Neritina virginica

, 1983
The LC50 of Neritina virginica (gastropod) to hexaolorocyclohexane (C6H6Cl6) was determined. A series of experiments was prepared during a period of 96 hours using different hexaclorocyclohexane concentrations. The LC50 to Neritina virginica was 1,482 mg hexaclorocyclohexane/l.

Probing Cinnamamides and Benzamides as Anthelmintics: Discovery of Potent Drug‐Like Agents Against Angiostrongylus cantonensis

Chemical Biology &Drug Design, Volume 108, Issue 1, July 2026.
Cynnamoyl benzylpiperazine was identified as drug‐like derivative of cinnarizine with anthelmintic activity against A. cantonensis. In this work, 15 out of 31 derivatives showed improved anthelmintic activity with increased solubility. A SAR study was carried out to determine the molecular features involved in such effect.
