  Cephalosporin-derived inhibitors of β-Lactamase. Part 4: The C3 substituent

  摘要：

  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. (C) 2002 Elsevier Science Ltd. All rights reserved.
