Abstract
Mosquitoes are responsible for serious public health problems worldwide, and as such, Aedes aegypti and Aedes albopictus are important vectors in the transmission of dengue, chikungunya, and Zika in Brazil and other countries of the world. Due to growing resistance to chemical insecticides among populations of vectors, environmentally friendly strategies for vector management are receiving ever more attention. Essential oils (EOs) extracted from plants have activities against insects with multiple mechanisms of action. These mechanisms hinder the development of resistance, and have the advantages of being less toxicity and biodegradable. Thus, the present study aimed to evaluate the chemical composition of the EOs obtained from Piper capitarianum Yunck, as well as evaluating their insecticidal potential against Aedes aegypti and A. albopictus, and their toxicity in relation to Artemia salina. The yields of the EOs extracted from the leaves, stems, and inflorescences of P. capitarianum were 1.2%, 0.9%, and 0.6%, respectively, and their main constituents were trans-caryophyllene (20.0%), α-humulene (10.2%), β-myrcene (10.5%), α-selinene (7.2%), and linalool (6.0%). The EO from the inflorescences was the most active against A. aegypti and A. albopictus, and exhibited the respective larvicidal (LC50 = 87.6 μg/mL and 76.1 μg/mL) and adulticide activities (LC50 = 126.2 μg/mL and 124.5 μg/mL). This EO was also the most active in the inhibition of AChE, since it presented an IC50 value of 14.2 μg/mL. Its larvicidal effect was observed under optical and scanning electron microscopy. Additionally, non-toxic effects against A. salina were observed. Docking modeling of trans-caryophyllene and α-humulene on sterol carrier protein-2 (SCP-2) suggests that both molecules have affinity with the active site of the enzyme, which indicates a possible mechanism of action. Therefore, the essential oil of P. capitarianum may be used in the development of new insecticide targets for the control of A. aegypti and A. albopictus in the Amazonian environment.

Croton argyrophyllus Kunth Essential Oil-Loaded Solid Lipid Nanoparticles: Evaluation of Release Profile, Antioxidant Activity and Cytotoxicity in a Neuroblastoma Cell Line. SUSTAINABILITY 2020.

Abstract
The essential oil from Croton argyrophyllus Kunth is known for its antiproliferative, anti-inflammatory, antinociceptive, and anticancer activities, and is recognized as a source of phytochemicals for potential use in pharmaceutic and food sectors. Solid lipid nanoparticles (SLN) have been produced to load Croton argyrophyllus (CA) Kunth essential oil (CAEO) and its antioxidant properties evaluated in vitro as a new approach for the treatment of neurodegenerative diseases. Cetyl palmitate SLN loading CAEO (CAEO-SLN) with a mean particle size of 201.4 ± 2.3 nm (polydispersity index 0.211) have been produced by hot high-pressure homogenisation. The release of the oil followed the Korsmeyers-Peppas model. The risk of lipid peroxidation has been determined by applying the production of thiobarbituric acid-reactive substances (TBARS) standard assay. The antioxidant activity was determined by the capacity of the antioxidants existing in CAEO to scavenge the stable radical DPPH•. The cytotoxicity of CA Kunth essential oil-loaded SLN (CAEO-SLN) was evaluated in a human cell line SH-SY5Y (derived from human neuroblastoma) by determining the reduction of the yellow dye 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT). Both free essential oil (fEO) and loaded essential oil (CAEO-SLN) were demonstrated to inhibit the Fenton reaction. CAEO-SLN showed DPPH• radical scavenging capacity. The loading of the oil into cetyl palmitate SLN reduced the risk of cytotoxicity.

Abstract
Mosquito-borne diseases are currently considered as important threats to human health in subtropical and tropical regions. Resistance to synthetic larvicides in different species of mosquitoes, as well as environmental pollution, are the most common adverse effects of excessive use of such agents. Plant-derived essential oils (EOs) with various chemical entities have a lower chance of developing resistance. So far, no proper classification based on lethal concentration at 50% (LC50) has been made for the larvicidal activity of EOs against different species of Aedes, Anopheles and Culex mosquitoes. To better understand the problem, a summary of the most common mosquito-borne diseases have been made. Related articles were gathered, and required information such as scientific name, used part(s) of plant, target species and LC50 values were extracted. 411 LC50 values were found about the larvicidal activity of EOs against different species of mosquitoes. Depending on the obtained results in each species, LC50 values were summarized as follows: 24 EOs with LC50 < 10 µg/mL, 149 EOs with LC50 in range of 10- 50 µg/mL, 143 EOs having LC50 within 50- 100 µg/mL and 95 EOs showing LC50 > 100 µg/mL. EOs of Callitris glaucophylla and Piper betle against Ae. aegypti, Tagetes minuta against An. gambiae, and Cananga odorata against Cx. quinquefasciatus and An. dirus having LC50 of ~ 1 µg/mL were potentially comparable to synthetic larvicides. It appears that these plants could be considered as candidates for botanical larvicides.
