Effect of 7 alpha substitution of cephems on their beta-lactamase stability and affinity for penicillin-binding proteins in Morganella morganii.
Cephamycins, which have a methoxy group at the 7 alpha position of their cephalosporin nuclei, were highly stable against hydrolysis by a beta-lactamase purified from a clinical isolate of Morganella morganii, whereas their 7 alpha-H analogs were rapidly hydrolyzed by the enzyme. The high stability...
