NOVEL beta-LACTAMASE INHIBITOR AND METHOD FOR PRODUCING SAME

摘要

Currently available beta-lactamase inhibitors have an inadequate effect against beta-lactamases, which continue to increase constantly. There is a need for novel beta-lactamase inhibitors which can be used in the treatment of bacterial infections caused by resistant bacteria that are currently difficult to treat and that produce: class C beta-lactamase; extended-spectrum beta-lactamase (ESBL) belonging to classes A and D; KPC-2, which decomposes even carbapenem, the last bastion of beta-lactam antibiotics, belonging to class A; and the like. Provided are a compound shown by formula (I), a method for producing the same, a beta-lactamase inhibitor, and a method for treating bacterial infections.
