Synthesis and Biological Activities of Novel Pleuromutilin Derivatives with a Substituted Thiadiazole Moiety as Potent Drug-Resistant Bacteria Inhibitors
A series of novel pleuromutilin derivativespossessing thiadiazole moieties were synthesized via acylation reactions under mild conditions. The in vitro antibacterial activities of the derivatives against methicillin-resistant Staphylococcus aureus, methicillin-resistant Staphylococcus epidermidis, Escherichia coli, and Streptococcus agalactiae were tested by the agar dilution method and Oxford cup
