Editorial: The Global Threats of Increasing Antimicrobial Resistance Require New Approaches to Drug Development, Including Molecular Antimicrobial Adjuvants.

Antimicrobial resistance and the associated morbidity and mortality from untreatable common infectious organisms is an increasing threat to global public health. In 2019, the Antimicrobial Resistance Collaborators identified that antimicrobial resistance was directly responsible for up to 1.27 million deaths worldwide and was associated with up to 4.95 million deaths, with low-income and middle-income countries being the most severely affected. In 2019, before the COVID-19 pandemic began, they predicted that antimicrobial resistance could result in 10 million deaths per year by 2050, overtaking cancer as a leading cause of death worldwide. Therefore, there is an urgent need for new approaches to antimicrobial treatment. In June 2024, the findings from researchers at the Ineos Oxford Institute for Antimicrobial Research (IOI) and the Oxford University Department of Pharmacology in the UK reported the use of a small molecule that can work alongside antibiotics to suppress the development of antimicrobial resistance in bacteria. The SOS inhibitor molecule has been called OXF-077. This editorial aims to highlight the global threats from increasing antimicrobial resistance and the urgent need for new molecules that function through novel mechanisms of action, including molecular antimicrobial adjuvants.
