FORFARANDE FOR FRAMSTELLNING AV AMINOACYLDIPEPTIDPENICILLINER

摘要

New penicillins and their salts and esters particularly active against Gram-negative organisms such as Pseudomonas spp., and their preparation and administration. The penicillins are active against clinically important organisms against which well-known broad spectrum penicillins are inactive and may generally be designated as aminoacyldipeptide penicillins of unusual structure and properties.
