Article Abstract
Using indole-2-carboxylic acid and vanillic acid as raw materials, a series of 11 novel compounds (7a-7k) were synthesized by chemically linking indole-2-carboxylic acid and vanillic acid through an aminothioureido group. The antibacterial activity of these compounds against Vibrio harveyi and Vibrio parahaemolyticus was evaluated using the agar perforating method. The results indicated that compounds 7g-7j exhibited superior antibacterial activity against both strains compared to the positive control, with 7g showing the best performance. Structure-activity relationship analysis suggested that alkylation of the nitrogen atom in the indole ring could enhance the antibacterial effect, and shorter carbon chains were associated with better antibacterial activity.

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.
