Article Abstract
The use of antibiotics has greatly improved the treatment of bacterial infections; however, its abuse and misuse has led to a rapid rise in multidrug-resistant (MDR) bacteria. Therefore, the search for new antimicrobial strategies has become critical. Natural flavonoids, a class of widely existing phytochemicals, have gained significant research interest for their diverse biological activities and antibacterial effects on various drug-resistant bacteria. This review summarizes the latest research progress on flavonoids, with a particular focus on several flavonoids exhibiting certain antibacterial activity, and explores their antibacterial mechanisms, including disruption of cell membranes and cell walls, inhibition of proteins and nucleic acids, interference with signal transduction, suppression of efflux pump activity, and inhibition of biofilm formation and virulence factor production. Additionally, we have reviewed the synergistic combinations of flavonoids with antibiotics, such as the combination of quercetin with colistin or EGCG with tetracycline, which significantly enhance therapeutic efficacy.

This study investigates a multifunctional hydrogel system integrating carboxymethyl cellulose (CMC) in a 3D-printed limonene (LIM) scaffold coated with poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS). The system allows to enhance wound healing, prevent infections, and monitor the healing progress. CMC is crosslinked with citric acid (CA) to form the hydrogel matrix (CMC-CA), while the 3D-printed limonene (LIM) scaffold is embedded within the hydrogel to provide mechanical support.

Salmonella enterica serovar Typhi, the etiological agent of Typhoid fever, remains a critical public health concern associated with high morbidity in many developing countries. The widespread emergence of multidrug-resistant (MDR) Salmonella Typhi strains against the fluoroquinolone group of antibiotics, particularly ciprofloxacin, poses a significant global therapeutic challenge with underlying resistance due to mutations in quinolone-resistance determining region (QRDR) of gyrA gene, encoding DNA gyrase subunit A (GyrA). In pursuit of alternative therapeutic candidates, the present study was designed to evaluate ciprofloxacin analogues against prevalent GyrA mutations (S83F, D87G, and D87N) to overcome fluoroquinolone resistance through machine learning (ML)-based approach.

Bacterial persisters are a subpopulation of cells that exhibit a transient non-susceptible phenotype in the presence of bactericidal antibiotic concentrations. This phenotype can lead to the survival and regrowth of bacteria after treatment, resulting in relapse of infections. It is also a contributing factor to antibacterial resistance.

Surgical resection remains the frontline intervention for cancer; however, postoperative tumor recurrence and wound infection remain critical unmet challenge in surgical oncology. Herein, an all-in-one nanowired hydrogel (V-Hydrogel) is developed through a facile one-step assembly employing enzyme-mimetic VO nanowires and bactericidal crosslinker THPS. The V-Hydrogel reserves the glutathione peroxidase-, peroxidase-, catalase-, and oxidase-mimetic enzymatic activities derived from vanadium oxide nanowires, thereby exhibiting efficient tumor-specific catalytic therapy.
