Mangroves are highly productive ecosystems distributed in tropical and subtropical regions in the world. Many different species of fungi can be isolated from this ecosystem. These fungi can be a rich source of useful antimicrobial compounds.

Treatment of SH-SY5Y neuroblastoma cells with a carvacrol-based Morita-Baylis-Hillman adducts (MBHAs) promotes cell death by apoptosis, with low toxicity in vivo, emphasizing the potential of carvacrol acrylate/2-naphthyl adduct for future development of anticancer agents.

The species of the bloodstains can be identified rapidly, non-destructively and accurately based on a handheld near infrared spectroscopy spectrometer and convolutional neural network-support vector machine algorithm.

Licarin A derivative DL21 displays high toxicity to Leishmania amazonensis.

Ab initio molecular dynamics calculations were carried out to evaluate the interaction between the chitosan monomer and calcium ion, considering both the gas phase and microsolvation environments.

Cave fungi from Gruta do Catão biodegraded the pyrethroid pesticide gamma-cyhalothrin, showing potential for biotechnological applications. Furthermore, a biodegradation pathway was presented.

Photodecarboxylation reaction yield and Chlorella variabilis fatty acid photodecarboxylase (CvFAP) photostability were increased by using violet light emitting diode (LED) (397 nm) when compared to the high-power blue LED (439 nm).

Laser flash photolysis of 2-alkoxythioxanthones generates the corresponding triplet excited state which can lead to the formation of reactive intermediates.

Black carbon concentration was measured on particulate matter (PM₁₀ and PM_2.5) collected on filters from the Metropolitan Region of Rio of Janeiro during 2018 and 2019.

Chemical and enzymatic combinatorial synthesis in continuous-flow is proposed as an innovative technology to obtain aroma esters.

Differences in composition between traditional Coffea canephora varieties (conilon and robusta) are smaller than among them and intervarietal hybrid coffees.

Practical optimizations of the reaction medium improved the challenging enzymatic resolution of tertiary alcohols.

Identification and quantification of gallic acid using the high-performance liquid chromatography (HPLC) method in the methanolic extract obtained from Schinus terebinthifolius leaves, branches, and fruits.

Chemical profiling of Annona tomentosa stem bark and evaluating its impact on breast (MCF-7) three-dimensional (3D) tumor spheroids.

Costunolide was isolated from the resin oil of Saussurea lappa. The products of the microwave-assisted Pd^II-catalyzed reaction of costunolide were isolated by semi-preparative high performance liquid chromatography (HPLC) and purified by analytical HPLC. The products were identified by nuclear magnetic resonance (NMR).

The identification and quantification of input quantities to the measurement uncertainties were estimated by dynamic light scattering using reference material polyvinylpyrrolidone coated silver nanoparticles.

Stem barks of Luehea ochrophylla were exposed to different doses of gamma radiation. The dose of 5.0 kGy was effective to achieve total decontamination. The trans-aconitic acid has its concentration significantly altered with radiation in phenolic fraction being citric acid the main radiolytic product formed.

Structural characterization of biomass from cultivated red algae Crassiphycus birdiae in natura and residual.
