A series of mercaptoacetic acid thiol esters h***e been identified as metallo-beta-lactamase inhibitors. Electrospray mass spectrometry (E***S) has shown that irreversible inhibition of the Bacillus cereus II metallo-beta-lactamase by SB214751, SB214752, and SB213079 was concomitant with a 90-Da increase in mass of the enzyme. Tryptic digestion of the B. cereus II inhibited with SB214751 illustrated that the peptide fragment, containing the only cysteine of the enzyme, 常州凌驰化工主要生产中间体分析***合成,值得信赖
