Several types of furanomycin analogues were synthesized and investigated with respect to their antibacterial activity. Two different synthetic pathways were developed, based on aldol reactions/ring closing metathesis and an ester enolate Claisen rearrangement. Only the natural product and its desmethyl derivative showed antibacterial activity, pointing towards a narrow structure-activity relationship.

A new hydrindane derivative, asperhydrindane A (), along with two known sterol analogues [isocyathisterol () and ganodermasides D ()] were isolated from the mangrove-derived fungus GXIMD 03158 attaching to the mangrove L. The structure of was elucidated based on extensive spectral analysis, HRESIMS, and calculated ECD methods. All compounds were evaluated for antibacterial activity.

The rapid worldwide spread of antibiotic resistance is quickly becoming an increasingly concerning problem for human healthcare. Non-antibiotic antibacterial agents are in high demand for many Gram-negative bacterial pathogens, including . -targeting phages are among the most promising alternative therapy options.

is a widely distributed nosocomial pathogen that causes various acute and chronic infections, particularly in immunocompromised patients. In this study, the activities of the K9-specific virulent phage AM24 and phage-encoded depolymerase DepAPK09 were assessed using in vivo mouse sepsis and burn skin infection models. In the mouse sepsis model, in the case of prevention or early treatment, a single K9-specific phage or recombinant depolymerase injection was able to protect 100% of the mice after parenteral infection with a lethal dose of of the K9-type, with complete eradication of the pathogen.

Magnolol (MG) and honokiol (HK) are bioactive compounds extracted from and trees with significant pharmacological properties, including antioxidant and antibacterial activity. However, their poor water solubility and low bioavailability limit the therapeutic potential. To address these limitations, this study aims to develop MG and HK formulations by co-electrospinning using custom-synthesized β-cyclodextrin-oligolactide (β-CDLA) derivatives.
