Article Abstract
This work presents a comprehensive investigation into the design, synthesis, and evaluation of a novel series of 4-alkoxyquinolines as potential antimycobacterial agents. The design approach, which combined molecular simplification and chain extension, resulted in compounds with potent and selective activity against both drug-susceptible and multidrug-resistant strains. The lead molecule, targeting the cytochrome complex, exhibited favorable kinetic solubility and remarkable chemical stability under acidic conditions. Despite ADME evaluations showing low permeability and high metabolism in rat microsomes, the lead compound exhibited bacteriostatic activity in a murine macrophage model of TB infection and demonstrated promising exposure following gavage in mice, with an AUC of 127.5 ± 5.7 μM h. To the best of our knowledge, for the first time, a simplified structure from 2-(quinolin-4-yloxy)acetamides has shown such potential. These findings suggest a new avenue for exploring this chemical class as a source of antituberculosis drug candidates.

The tumor suppressor DAB2IP, a RasGAP and cytoplasmic adaptor protein, modulates signal transduction in response to several extracellular stimuli, negatively regulating multiple oncogenic pathways. Accordingly, the loss of DAB2IP in tumor cells fosters metastasis and enhances chemo- and radioresistance. DAB2IP is rarely mutated in cancer but is frequently downregulated or inactivated by multiple mechanisms.

Developing a therapeutic target for bacterial disease is challenging. In silico subtractive genomics methodology offer a promising alternative to traditional drug discovery methods. Streptococcus agalactiae infections depend on two crucial criteria: drug-resistance and the existence of virulence factors.

Microbial electrochemical system-enhanced constructed wetland (MES-CW) attracts more attention for antibiotic-contaminated wastewater treatment, but the effect of bioelectrochemistry on resistance genes is still unclear with the removal of antibiotic. In this study, the antibiotic resistance genes (ARGs) dynamics, driving factors and transmission mechanism in effluent and substrate samples were investigated under decreasing sulfamethoxazole (SMX) pressure. Bioelectrochemistry was suitable for reducing the risk of ARGs proliferation and transmission at concentration of 0.

The time-consuming and repetitive rediscovery of known molecules has long hindered the efficient identification of novel drug leads from natural sources. Metabologenomics, the synergistic integration of metabolomics and genomics, has emerged as a powerful strategy to circumvent these challenges, enabling targeted discovery of new chemical entities. In this study, we developed a 2D-NMR-based metabologenomics workflow integrated with high-throughput activity screening to rapidly identify a novel family of antibiotic macrolides, samsumycins (-), from the deep-sea sp.

Carbapenemase-producing (CPEn) has globally emerged to be a severe threat to human health. However, the disease spectrum, impact on affected patients' outcomes, and transmission of CPEn are largely uncharacterized. We performed genome sequencing on a collection of CPEn clinical isolates spanning a six-year period, collating corresponding disease spectrum data and patient prognosis.
