High-throughput natural products chemistry methods have facilitated the isolation of eight new (1-8) and two known (9 and 10) beilschmiedic acid derivatives from the leaves of a Gabonese species of Beilschmiedia. Compounds 3-10 were isolated in microgram quantities, and the NMR data for structure elucidation and dereplication were acquired utilizing a Bruker BioSpin TCI 1.7 mm MicroCryoProbe. All of the compounds were screened for cytotoxic and antibacterial activity against NCI-H460 human lung cancer cells and a clinical isolate of methicillin-resistant Staphylococcus aureus, respectively. This is the first report of cytotoxic activity for the endiandric/beilschmiedic acid class of compounds.

In this study, a nanocomposite based on copper oxide-zinc oxide nanoparticles and Gum Arabic (GA@CuO-ZnO nanocomposite) was successfully synthesized using green method. Characterization results revealed that the prepared nanocomposite appeared at the nanoscale level, showed excellent dispersion, and formed stable colloidal nano-solutions. The bimetallic GA@CuO-ZnO nanocomposite was evaluated for its anticancer, antibacterial, and antifungal properties.

Background: Novel platforms using nanotechnology-based medicines have exponentially increased in our daily lives. The unique characteristics of metal oxide and noble metals nanoparticles make them suitable for different fields including antimicrobial agents, cosmetics, textiles, wound dressings, and anticancer drug carriers.
Methods: This study focuses on the biosynthesis of small-sized SNPs using exo-metabolites of Fusarium oxysporum via bioprocess optimization using Plackett-Burman (PBD) and central composite designs (CCD) while evaluating their multifaceted bioactivities.

Antimicrobial peptides (AMPs) are crucial components of the innate immune system in all living organisms, playing a vital role in the body's defense against diseases and infections. The immune system's primary functions include preventing disease-causing agents from entering the body and eliminating them without causing harm. These peptides exhibit broad-spectrum activity against bacteria, viruses, fungi, parasites, and cancer cells.

Managing wounds and accompanying consequences like exudation and microbiological infections is challenging in clinical practice. Bioactive compounds from traditional medicinal plants help heal wounds, although their bioavailability is low. This study uses sodium alginate (SA), gelatin (G), and Santalum album oil (SAL) to 3D print a polymeric hydrogel scaffold to circumvent these difficulties.
