A new generation of B-lactamase inhibitors is likely to reach the market in the upcoming year. These broad-spectrum inhibitors exhibit activity against the most feared class B metallo-B-lactamases maintaining the inhibition of other enzymes. Recently AAC has published three papers that describe the mechanistic bases of taniborbactam resistance among metallo-enzymes. This knowledge is crucial to understand the limitation of these compounds in clinical practice. Today, we will discuss this topic with some of the authors of the mentioned papers. Welcome to the editors in conversation.
- The activity and chemical basis of new generation B-lactamase inhibitors with activity against metallo-B-lactamases.
- Taniborbactam as an example of novel B-lactam, B-lactam inhibitors
