A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Enabling antibiotics to combat multidrug resistant bacteria

Global increase in antibiotic resistance causes tens of thousands of deaths each year. Infections by pathogenic Gram-negative bacteria are the most common, with β-lactam antibiotics being the most widely used treatment. The most important type of resistance to them is mediated via β-lactamases. The recent clinical introduction of avibactam and vaborbactam as serine-β-lactamase inhibitors is a major advance. However, the metallo-β-lactamases are of particular concern because they catalyse the hydrolysis of almost all types of β-lactam antibiotics and all serine-β-lactamase (SBL) inhibitors, including avibactam.
Metallo-β-lactamases are particularly challenging targets because of the need to obtain potency against the different clinically relevant subtypes, which differ in the loops surrounding the active sites. The bacterial MBLs belong to the MBL superfamily that up to date includes >30000 members. Bacterial and human MBLs present high active site similarity and high structural similarity. The superfamily contains human MBLs that should not be inhibited by bacterial MBL inhibitors.
In this talk, I will describe the recent work on the mechanisms, structure and inhibition of bacterial metallo and serine-β-lactamases and the impact of my work in the field of antibiotic resistance that has led to the development of a potential drug candidate suitable for clinical development.
