: Phytochemical Profiling, and Evaluation of Its Biological Activities , , and .

In this work, the leaves of were macerated with hexane, chloroform, and methanol, respectively. The phytochemical profiles of hexane and chloroform extracts were unveiled using GC/MS, whereas the chemical composition of the methanol extract was analyzed using UPLC/MS/MS. The antibacterial activity of extracts was determined against gram-positive and gram-negative strains through the minimal inhibitory concentration assay, and studies were implemented to analyze the interaction of phytoconstituents with bacterial peptides.

Green Synthesis of Silver Nanoparticles with Extracts from : Characterization and Bioactivities.

In this work, the hexane, chloroform, and methanol extracts from were utilized to green-synthesize silver nanoparticles (Kf-, Kf-, and Kf-AgNPs). The Kf-, Kf-, and Kf-AgNPs were characterized by spectroscopy and microscopy techniques. The antibacterial activity of AgNPs was studied against bacteria strains, utilizing the microdilution assay.

Recent Advances in the Therapeutic Potential of Carotenoids in Preventing and Managing Metabolic Disorders.

Carotenoids constitute compounds of significant biological interest due to their multiple biological activities, such as antimicrobial, anticancer, antiadipogenic, antidiabetic, and antioxidant properties. Metabolic syndrome (MetS) comprehends a series of metabolic abnormalities (e.g.

Use of Novel Homochiral Thioureas Camphor Derived as Asymmetric Organocatalysts in the Stereoselective Formation of Glycosidic Bonds.

We synthesized six new camphor-derived homochiral thioureas -, from commercially available (1)-(-)-camphorquinone. These new compounds - were evaluated as asymmetric organocatalysts in the stereoselective formation of glycosidic bonds, with 2,3,4,6-tetra--benzyl-D-glucopyranosyl and 2,3,4,6-tetra--benzyl-D-galactopyranosyl trichloroacetimidates as donors, and several alcohols as glycosyl acceptors, such as methanol, ethanol, 1-propanol, 1-butanol, 1-octanol, -propanol, -butanol, cyclohexanol, phenol, 1-naphtol, and 2-naphtol. Optimization of the asymmetric glycosylation reaction was achieved by modifying reaction conditions such as solvent, additive, loading of catalyst, temperature, and time of reaction.

Stabilization of Anthocyanins from Coffee ( L.) Husks and In Vivo Evaluation of Their Antioxidant Activity.

Coffee ( L.) is one of the most popular and widely consumed products throughout the world, mainly due to its taste, aroma, caffeine content, and natural antioxidants. Among those antioxidants, anthocyanins are one of the most important natural pigments, which can be found in coffee husks.
