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.

Integrated Metabolomics and Network Pharmacology Reveal Anti‐Aging and Anti‐MRSA Activities of Cucumis melo Var. flexuosus

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
“Three fruit (LG, SH, and WH) and one leaves (LGLV) genotypes of snake melon were chemically profiled by LC‐HRMS. LGLV was chemically distinct and was active against MRSA as evidenced by an in vivo model. Moreover, LGLV counteracted H2O2‐induced cell senescence.
