Researchers at Shandong Second Medical University have developed a dimethyl quaternary ammonium derivative of harmane that shows strong potential for attacking the bacterium through diverse mechanisms.
GSK plc and the Fleming Initiative have announced six major new research programs to find new ways to slow the progress of antimicrobial resistance (AMR). The Fleming Initiative is a collaboration established by Imperial College London and Imperial College Healthcare NHS Trust to help tackle AMR. Each of the new programs will begin by early next year and are fully funded for 3 years.
Staphylococcus aureus is a gram-positive bacterium that is ubiquitous on human skin and normally does not cause problems, but when it enters the body, it can cause serious infections. The growing prevalence of methicillin-resistant S. aureus (MRSA) highlights the need for next-generation antibiotics against it.
Researchers from Sungkyunkwan University and the Ulsan National Institute of Science and Technology (UNIST) have patented compounds reported to be useful for the treatment of Staphylococcus aureus infections.
Effective vaccines against Staphylococcus aureus remain out of reach: 10 candidates that showed promise in preclinical animal models have failed in clinical trials. Researchers at Third Military Medical University and collaborators reasoned that one of the reasons might be that 70%-80% of the population has developed antibodies to the pathogen.
According to the World Health Organization (WHO), multidrug-resistant pathogens caused over 1.27 million deaths worldwide in 2020. And figures are rising, with projections pointing to antimicrobial resistance surpassing cancer as the leading cause of death by 2050. Now, researchers at the HUN-REN Biological Research Center have unveiled the role of pre-existing genetic variabilities and specific cross-resistance patterns among several antibiotics designed to combat gram-positive bacteria.

Caseinolytic protease P (ClpP) is a conserved serine protease present in both bacteria and humans, essential for maintaining protein quality by degrading misfolded proteins.
It was hypothesized that the MEK1/2 inhibitor ATR-002 could reduce inflammation and clear Staphylococcus aureus infection during cystic fibrosis, thus potentially showing a dual effect.
The inappropriate use of antibiotics over long periods of time has led to increasing bacterial drug resistance. Quinolones are among the most effective and widely used antibacterials, and there are ongoing efforts to develop new quinolone-based drugs able to overcome emerging bacterial drug resistance.
