-
Antibiotics such as penicillin are called, collectively, beta-lactams, and enzymes that break down these antibiotics and confer drug resistance are called beta-lactamases, which is why the term beta-lactamase may pop up in this blog entry from time to time.

NXL 104 is a compound that inhibits several classes of bacterial enzymes called beta-lactamase that break down and activate beta-lactam antibiotics such as: Cephalosporin, a class to which ceftaroline belongs; penicillins; and carbapenems, making the pathogens producing these enzymes resistant to these antibiotics.
