Abstract
Beta-lactamase inhibitors which are aminoacid esters of 6-alpha- and 6-beta-(hydroxymethyl)pencillanic acid 1,1-dioxides; pharmaceutically-acceptable salts thereof; conventional esters thereof which are hydrolyzable in vivo; bis-methanediol esters thereof; or mixed methanediol esters with said beta-lactamase inhibitors and sulbactam. Pharmaceutical compositions comprising said beta-lactamase inhibitors and a conventional beta-lactam antibiotic, said compositions useful in the treatment of bacterial infections. Compounds useful as intermediates in the synthesis of said beta-lactamase inhibitors. Antibacterial mixed bis-methanediol esters of said aminoacyloxymethyl penicillanic acid 1,1-dioxides and ampicillin or amoxicillin, also useful in the treatment of bacterial infections; and intermediates therefor.
