Cephalosporin-derived inhibitors of beta-lactamase. Part 4: The C3 substituent.

New C3-substituted beta-lactamase inhibitors were prepared and evaluated against representative class A and class C enzymes. It was possible to improve simultaneous inhibitory activity of both classes of serine hydrolase. Other inhibitors showed high selectivity for either the class C cephalosporinases or the class A penicillinases. This represents the first time that cephalosporin-derived inhibitors have demonstrated selectivity for the class A beta-lactamases.

Coupling reactions of cephalosporin sulfones: A stable 3-stannylated cephem

matrix presented The first stable 3-metalated cephalosporin is reported and shown to be an excellent synthetic precursor to a number of prospective β-lactamase inhibitors.
