Special Issue Information

Dear Colleagues,

Natural products have long been a valuable source of active compounds with diverse structures and a wide range of biological activities. Approximately 50% of current pharmaceuticals are derived directly or indirectly from natural products, primarily from plants. This has created a vibrant research environment focused on potential medical treatments for some of the world’s most pressing diseases, including chronic and infectious illnesses. Given the complex impacts of these diseases on quality of life for the global population, along with the side effects associated with their treatments, there is an urgent need for effective management strategies. The development of natural products is a significant alternative, as modern technology and in silico research have enhanced the discovery, design, and evaluation of more targeted pharmaceutical compounds.

For this Special Issue, we invite submissions focused on basic and computational sciences that explore the pharmaceutical applications of natural products in improving human health in the context of chronic and infectious diseases. We welcome studies on drug extraction, identification, and purification in both preclinical and clinical research. We invite submissions on topics including, but not limited to, cardiovascular diseases, cancers, chronic respiratory and kidney diseases, and infectious diseases caused by microorganisms that affect the global population.

Background/Objectives: The increasing prevalence of multidrug-resistant Staphylococcus aureus represents a major clinical challenge, primarily driven by the acquisition of multiple resistance mechanisms. Among these, efflux pumps such as NorA play a pivotal role in quinolone resistance by promoting active drug extrusion and reducing intracellular antibiotic levels. This study evaluated the synthetic chalcone CMA4DMA as a potential NorA efflux pump inhibitor and modulator of bacterial resistance. Methods: Antimicrobial susceptibility assays were conducted against S. aureus SA1199 (wild-type) and SA1199B (NorA-overexpressing) strains. The minimum inhibitory concentration (MIC) of CMA4DMA and its modulatory effects on norfloxacin and ethidium bromide were determined. Efflux inhibition was assessed by ethidium bromide accumulation and SYTOX Green assays. Molecular docking and in silico ADMET analyses were performed to predict binding affinity and pharmacokinetic parameters. Results: CMA4DMA exhibited no intrinsic antibacterial activity (MIC ≥ 1024 µg/mL) but reduced the MIC of norfloxacin from 32 to 8 µg/mL and that of ethidium bromide from 32 to 8 µg/mL in SA1199. In SA1199B, reductions from 64 to 16 µg/mL and from 64 to 32 µg/mL were observed, respectively. Fluorescence increased by 15% without affecting membrane integrity. Docking revealed a binding affinity of −7.504 kcal/mol, stronger than norfloxacin (−7.242 kcal/mol), involving key residues Leu218, Ile309, Arg310, and Ile313. ADMET data indicated high intestinal absorption (88.76%) and permeability (Papp = 1.38 × 10−5 cm/s). Conclusions: CMA4DMA effectively restored norfloxacin susceptibility in resistant S. aureus strains, highlighting its potential as a promising scaffold for developing novel efflux pump inhibitors and antibiotic adjuvants.
