Summary: Drug repositioning has become an attractive alternative for treating infections caused by multidrug resistant microorganisms due to the global spread of microbial resistance and challenges in discovering new antibiotics. Various non-antibiotic drugs have shown significant antimicrobial activity, especially when combined with antibacterials, and the presence of aromatic rings in the molecular structure contributes to this activity. This review highlights the potential repositioning of non-antibiotic drugs as promising candidates for treating severe bacterial infections caused by extensively resistant bacteria.

Summary: Infections pose an escalating global threat due to the alarming rise in resistant microbial pathogens. This review summarizes the causes of antimicrobial resistance, discusses various approaches to the discovery of new anti-infective drugs, and focuses on the strategy of drug repurposing, offering critical remarks on the repurposing of non-antibiotics. A comprehensive overview of drugs tested for their antimicrobial activity is provided to support existing anti-infective therapeutics.

Summary: Researchers have studied antimicrobial peptides in the venom of Lycosa sinensis and found that two peptides have inhibitory activity against multiple drug-resistant bacteria, and exhibit synergistic therapeutic effects with traditional antibiotics. These peptides disrupt the integrity of bacterial cell membranes and inhibit bacterial growth within a short period of time.

Summary: The study revealed that Mycobacterium tuberculosis developed resistance to arylamide compounds through mutations in the Rv2571c gene, which is involved in the import of these compounds. Alterations in Rv2571c led to antibiotic resistance, highlighting its crucial role in compound transport.

Summary: The outpatient use of systemic antibacterials among adults in Finland decreased from 2008-2019, including a significant decrease in wide-spectrum antibiotics. Although the overall yearly costs for outpatient antibiotics slightly decreased, the cost per prescription increased.

Summary: This study explores the targets for antimicrobial stewardship (AMS) interventions for medical antibiotic prophylaxis (AP) in adult patients. Potential targets include addressing underutilization of antibiotic-sparing strategies, reducing unnecessary AP beyond recommended indications, reducing the use of broad-spectrum AP, controlling the duration of AP, evaluating the role of antibiotic cycling, and addressing research gaps regarding appropriate indications and regimens for medical prophylaxis.

Summary: Caves hold a unique microbial world that could potentially serve as a source of antimicrobial and anticancer drugs. The historical use of cave environments to treat respiratory infections highlights the potential of cave microorganisms in drug discovery. The oligotrophic conditions in caves enhance competition among microbial communities, leading to the production of unique antimicrobial agents.

Summary: This study investigated the antibiotic resistance patterns and clinical distribution of blood culture-positive isolates at Suining Central Hospital between 2018 and 2021. The results showed a rising incidence of bacterial antibiotic resistance. Clinicians should consider the importance of blood culture antibiotic susceptibility testing to ensure effective treatment.

Summary: This study investigated the antimicrobial resistance profile of clinical samples from Yasuj teaching hospitals. The majority of bacterial isolates were gram-negative, with Escherichia coli being the most common. Resistance to norfloxacin antibiotic was more common in internal medicine, infectious, and emergency wards. All cases of oxacillin were resistant.

Summary: With increasing incidence of antimicrobial resistance, novel and effective antibacterials are urgently needed. This study assessed the antibacterial activity of porphyrin-based XF drugs, and found that they exhibited significant activity against Gram-positive bacteria, with the light-activated photodynamic mechanism enhancing their efficacy. The XF drugs also showed synergy with conventional antibiotics and demonstrated antibiofilm effects.

Summary: The process of membrane disruption by antimicrobial agents depends on the aggregation state of the attacking agent. The study demonstrated the feasibility of separating antifungal activity from hemolytic activity by controlling the molecule's tendency to aggregate or by attaching facial amphiphiles to the antimicrobial agent. These findings suggest new strategies for improving antimicrobial therapies.

Summary: A hospital-wide intervention focusing on evaluating clinically significant discordance and providing alternative therapy recommendations improved prescribing practices, resulting in a higher proportion of patients receiving empiric therapy concordant with prior culture results and a shorter time to receiving concordant therapy. Unnecessary vancomycin therapy duration was also reduced.

Summary: The benzoxaborole series has shown antimicrobial activity against Escherichia coli, with resistant mutants showing mutations in the enoyl acyl carrier protein FabI. The physical interaction between benzoxaborole and FabI is dependent on the cofactor NAD(+), providing further scope for development against Gram-negative pathogens.
