Problems solved by technology

Due to the continuous increase of bacterial resistance due to the abuse of antibiotics, and the limitation of digestive tract absorption, the currently marketed carbapenems can only be administered as injections in clinical practice, and the clinical utilization is not high. The half-life of penem is relatively short, which can no longer meet the clinical needs

Description

1. Technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to penem compounds containing mercaptopyrrolidine carboxamidotriazine, their pharmaceutically acceptable salts, their easily hydrolyzed esters, their isomers, their hydrates, and their esters or Hydrates of salts, preparation methods of these compounds, pharmaceutical compositions containing these compounds, and uses of these compounds in the preparation of medicaments for treating and / or preventing infectious diseases. 2. Background technology [0002] Carbapenem antibiotics are a class of β-lactam antibiotics developed in the 1970s. It has attracted much attention because of its broad antibacterial spectrum, strong antibacterial activity, and stability to β-lactamase. Its structural feature is that the sulfur at the 1-position of the penicillane core is replaced by carbon, and the 2-position has a double bond, which combines the five-membered ring of penicillin an...
