Rational Design of N‐2‐(7‐Chloroquinolin‐4‐ylamino)ethyl Amides Active Against Chloroquine‐Resistant Plasmodium falciparum

Archiv der Pharmazie, Volume 359, Issue 10, October 2026.
Of 22 chloroquine (CQ) analogs, 16 showed IC503D7 values of 27–555 nM; their activity against the CQ‐resistant K1 strain and in silico/vitro hepatotoxicity were evaluated. Benzamides with chlorine and nitro groups were most active, showing IC50K1 and RI values lower than CQ and cytotoxic concentrations well above inhibitory concentrations.

Larvicidal and cytotoxic activities of exopolysaccharides produced by thermophilic bacteria

International Microbiology
Abstract EPSs synthesized by thermophilic bacteria are natural biopolymers that have recently garnered attention due to their potential applications in areas such as pharmaceuticals and biomedicine. In this study, EPSs produced by five distinct thermophilic bacterial isolates from hot springs in Turkey were purified using ion exchange and gel ...

Seasonal and Regional Variation of the Chemical Composition and Antimicrobial Activity of Essential Oils From Piper marginatum Jacq.

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Evaluating Piper marginatum essential oils across three Brazilian biomes reveals significant chemical and antimicrobial variations driven by seasonal and regional factors. Sixty compounds are identified, including a novel (Z)‐phenylpropanoid reported for the first time. Multivariate analysis correlates environmental stressors with specialized metabolic

Integrated Experimental, Chemometric, and In Silico Analyses of Larvicidal Supercritical Extracts From Myrtaceae Species Against Aedes aegypti

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The cross‐validated regression tree showed modest predictive performance. Mortality was not significantly associated with the first two PCA axes. Molecular modeling generated testable ligand–target hypotheses. Psidium cattleianum had lower LD50. The larvicidal activity of the crude extracts could not be attributed to individual constituents.

β‐myrcene: A nature‐identical compound for sustainable aquaculture

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Sustainability is essential for the continued development of aquaculture. A key aspect of sustainable aquaculture involves using natural and organic compounds as alternatives to chemical counterparts. Herbal‐derived compounds have gained significant attention because of their eco‐friendly properties and health benefits.

Larvicidal activity of Ricinus communis extract against mosquitoes

Journal of Vector Borne Diseases, 2018
Vector control strategies play significant role in reducing the transmission of malaria, dengue and other vector-borne diseases. The control of vector population using synthetic insecticides has resulted in development of insecticide resistance and negative effects on humans and environment.

Synthesis of new isoxazole derivatives with larvicidal activity [PDF]

Proceedings of the 14th Brazilian Meeting on Organic Synthesis Proceedings, 2013
One of the major routes of detoxification (removal of free radicals) in Aedes aegypti mosquitos is the kynurenine pathway. In this biochemical pathway, the most important reaction is the conversion of 3-hydroxykynurenine (3-HK), a harmful metabolite that leads to insect death, into xanthurenic acid, a nontoxic substance. This conversion is performed by
