In this article, we propose to explore the chemical interaction between Pseudosphinx tetrio L. and Allamanda cathartica L. using different analytical methods, including an innovative electrochemical approach (called electrochemical ecology) and multivariate analysis, and we investigate the potential antimicrobial effects (antibacterial and antifungal activities) of this interaction in order to gain a better understanding of their specific interaction. The analytical study presents a similar chemical profile between the leaves of healthy and herbivorous A. cathartica and the excretions of the caterpillars. The similar analytical profile of the leaves of A. cathartica and the excretions of P. tetrio, and the difference with the caterpillar bodies, suggests a selective excretion of compounds by the caterpillar. The measured antimicrobial activities support the physicochemical tests. The natural products found selectively in the excretions (rather than in the body) could explain the ability of P. tetrio to feed on this toxic Apocynaceae species.

Plastoquinone is a key electron carrier in photosynthesis and an essential cofactor for the biosynthesis of carotenoids. p-Hydroxyphenylpyruvate dioxygenase (HPPD) is a vital enzymatic step in plastoquinone biosynthesis that is the target of triketone herbicides, such as those derived from the pharmacophore backbone of the natural product leptospermone. In this work, the inhibitory activity of a series of 2-acyl-cyclohexane-1,3-diones congeners derived from Peperomia natural products was tested on plant HPPD. The most active compound was a 2-acyl-cyclohexane-1,3-dione with a C11 alkyl side chain (5d; I50app: 0.18 ± 0.02 μM) that was slightly more potent than the commercial triketone herbicide sulcotrione (I50app: 0.25 ± 0.02 μM). QSAR analysis and docking studies were performed to further characterize the key structural features imparting activity. A 1,3-dione feature was required for inhibition of HPPD. Molecules with a side chain of 11 carbons were found to be optimal for inhibition, while the presence of a double bond, hydroxy, or methyl beyond the required structural features on the cyclohexane ring generally decreased HPPD inhibiting activity.

El Schinus weinmanniifolia (Molle’i) es una de las plantas empleadas en forma de infusión de las hojas para tratar amigdalitis, dolores de garganta, tos e inflamaciones de la encía. Para tratar de establecer una relación entre los metabolitos secundarios presentes y sus actividades biológicas se determinó el Perfil Fitoquímico Cualitativo del extracto crudo, Compuestos fenólicos totales, Flavonoides Totales así como Actividad Antioxidante, Actividad Hemolítica y DL50 en Drosophila melanogaster. Los resultados revelaron la presencia de Taninos hidrolizables, saponinas y esteroles. En los bioensayos se observó elevada Actividad de Antioxidantes (IC=39,9%) y una actividad antimicrobiana del extracto bruto etanólico frente a cepas de E. coli, S. typhimurium, E. faecalis, P. aeruginosa, C. albicans. Se estableció una DL50 de 15,3 mg.mL en Drosophyla melanogaster y además una actividad hemolítica de IC50 de 179 µg.mL con una actividad del 55,9 %. Estos valores representaron un primer aporte a fin de determinar científicamente su actividad biológica y correlacionar con el contenido de moléculas.

Na madeira estão presentes inúmeras substâncias sintetizadas pela árvore como defensivos à estímulos ambientais. Tais substâncias podem ser fonte potencial de princípios ativos, incluindo os de ação larvicida contra o mosquito Aedes aegypti. A partir de revisão de literatura, foram encontrados 23 trabalhos científicos sobre a atividade larvicida de compostos presentes na madeira. Os estudos contemplaram a análise de 66 espécies vegetais pertencentes a 23 famílias botânicas. Cerca de 30% das espécies estudadas foram consideradas ativas. A espécie que apresentou o material bruto mais ativo foi Callitris glaucophylla, cujo óleo essencial apresentou CL50 = 0,69 ppm. Foram identificadas 23 moléculas potencialmente ativas, sendo o melhor resultado obtido pela tectoquinona isolada do extrato metanólico de Cryptomeria japonica, com CL50 = 3,3 ppm. Observou-se que a madeira pode ser fonte de larvicidas naturais com ação similar ao larvicida sintético organofosforado temefós, cujo valor de CL50 encontrado na literatura variou entre 2,3 a 9,4 ppm. Dentre as vantagens do uso de larvicidas de origem natural, destaca-se a maior biodegradabilidade e a menor toxicidade aos organismos não alvos quando comparados aos sintéticos, além da contribuição para o enfrentamento do problema da resistência dos insetos.
