The essential oils (EOs) isolated from the fresh aerial parts of Ruta chalepensis L. collected in North Lebanon were obtained by solvent-free microwave extraction (Milestone (R)), yielding 0.12% EO from both the leaves and a mixture of stems and leaves. The EOs were characterized by GC/MS analysis, and 27 components were identified, which were primarily ketones (88.0-93.2%). The main components were nonan-2-one and undecan-2-one. The antimicrobial activity of the EOs against a Gram-positive and a Gram-negative bacterium, a yeast, and a dermatophyte was evaluated using the broth-microdilution technique and expressed as minimal inhibitory concentration (MIC). The EOs revealed moderate in vitro antifungal activity against Trichophyton rubrum and Candida albicans.

Benzophenone Accumulates over Time from the Degradation of Octocrylene in Commercial Sunscreen Products

C. A. Downs, Joseph C. DiNardo, Didier Stien, Alice M. S. Rodrigues, Philippe Lebaron

Summary: The study investigated the presence of benzophenone in commercial sunscreen products, the increase in benzophenone concentration over time, and the source of benzophenone contamination from octocrylene degradation. The results showed that octocrylene can generate benzophenone through a reaction, and up to 70% of benzophenone in sunscreen products may be absorbed through the skin. Regulatory agencies should promptly review the safety of octocrylene as a benzophenone generator in SPF or any consumer products.

Identification of Antagonistic Compounds between the Palm Tree Xylariale Endophytic Fungi and the Phytopathogen Fusarium oxysporum

Morgane Barthelemy, Nicolas Elie, Gregory Genta-Jouve, Didier Stien, David Touboul, Veronique Eparvier

Summary: This study isolated endophytes from palm trees in French Guiana and discovered new compounds with antifungal properties against Fusarium oxysporum. The investigation also identified a previously unknown compound named focicin produced by the phytopathogen during competition. Chemical interactions between the endophytic strain and the phytopathogen were highlighted using MALDI-TOF MS imaging.

Characterization of Pseudomonas aeruginosa Quorum Sensing Inhibitors from the Endophyte Lasiodiplodia venezuelensis and Evaluation of Their Antivirulence Effects by Metabolomics

Summary: Pseudomonas aeruginosa, a critical priority pathogen with multidrug resistance, uses quorum sensing to collectively produce virulence factors. Fungal endophytes represent an under-explored source of novel quorum sensing inhibitors (QSI), with potential for discovering new antimicrobial agents. Lasiodiplodia venezuelensis, an endophytic strain, was found to have selective activity as a QSI against P. aeruginosa, leading to the isolation of compounds with anti-QS effects.

Summary: This study presents a simple and accessible method to detect, annotate, and quantify AHLs in bacterial culture media. The method utilizes an ultra-high-performance liquid chromatography system coupled with a mass spectrometer using a nontargeted FullMS data-dependent MS2 method. Results were processed using MZmine2 and analyzed by the Feature-Based Molecular Networking (FBMN) workflow in the Global Natural Products Social Networking (GNPS) platform. The study demonstrates the automatic annotation of known AHLs and the ability to search for unknown AHLs, even without analytical standards. The method also provides relative quantification information.

A Comparative Metabolomics Approach Demonstrates That Octocrylene Accumulates in Stylophora pistillata Tissues as Derivatives and That Octocrylene Exposure Induces Mitochondrial and Cell Senescence

Evane Thorel, Fanny Clergeaud, Alice M. S. Rodrigues, Philippe Lebaron, Didier Stien

Summary: This study investigates the effects of octocrylene on two coral species and reveals that it can cause mitochondrial dysfunction and cellular senescence. The impact on a second coral species suggests that environmental octocrylene pollution may affect various reef-building species. Additionally, the research demonstrates that octocrylene can be modified by organisms and its contamination levels in the food chain may have been underestimated.

Spectroelectrochemistry as a new tool for the quantification of UV filters in sun creams

Summary: This study quantified four UV filters used in cosmetics by spectroelectochemistry. Electrochemical activity of the filters resulted in modification of their absorption spectrum. Combining spectral deconvolution of spectra pairs was more accurate in identifying and quantifying UV filters than deconvolution of initial absorbance spectrum alone.

On the Fate of Butyl Methoxydibenzoylmethane (Avobenzone) in Coral Tissue and Its Effect on Coral Metabolome

Fanny Clergeaud, Maeva Giraudo, Alice M. S. Rodrigues, Evane Thorel, Philippe Lebaron, Didier Stien

Summary: The extensive use of sunscreen products has caused concerns about their environmental toxicity and the negative effects they have on ecologically important coral communities. Metabolomic analyses on Pocillopora damicornis exposed to the UV filter avobenzone (BM) revealed unidentified ions in the coral's metabolome. Further analysis found that BM-exposed corals had 57 ions with significantly different relative concentrations, including 17 BM derivatives and one major derivative, C16:0-dihydroBM. These findings suggest that BM exposure may impair the photosynthetic capacity of coral holobionts and that the impact of BM derivatives should be considered in future environmental assessments.

Summary: Chemical UV filters released into the aquatic environment can affect the development of fish eggs. This study evaluated the toxicity of six commonly used UV filters on the embryo-larval stages of zebrafish and found that octocrylene delayed hatching success while 2-ethylhexyl salicylate increased heartbeat rate.
