A “cephalosporin-like” cyclic depsipeptide: Synthesis and reaction with ß-lactam-recognizing enzymes

A “cephalosporin-like” cyclic depsipeptide: Synthesis and reaction with ß-lactam-recognizing enzymes Benzopyranones with retro-amide side chains as (inhibitory) β-lactamase substrates The synthesis and serine β-lactamase inhibitory activity of some phosphonamidate analogues of dipeptides The synthesis and SAR of rhodanines as novel class C β-lactamase inhibitors N-Aryl 3-halogenated azetidin-2-ones and benzocarbacephems, inhibitors of .beta.-lactamases Structure-based optimization of cephalothin-analogue boronic acids as β-lactamase inhibitors The synthesis and lactamase inhibitory activity of 6-(carboxymethylene)penicillins and 7-(carboxymethylene)cephalosporins Inhibition of the mammalian .beta.-lactamase renal dipeptidase (dehydropeptidase-I) by Z-2-(acylamino)-3-substituted-propenoic acids Synthesis and structure-activity relationship of new cephalosporins with amino heterocycles at C-7. Dependence of the antibacterial spectrum and .beta.-lactamase stability on the pKa of the C-7 heterocycle Spirocyclopropyl β-Lactams as Mechanism-Based Inhibitors of Serine β-Lactamases. Synthesis by Rhodium-Catalyzed Cyclopropanation of 6-Diazopenicillanate Sulfone
