Description

1. Technical field [0001] The present invention relates to mercaptopyrrolidine carbapenems substituted by formanilide, their easily hydrolyzed esters, their pharmaceutically acceptable non-toxic salts, their isomers, their hydrates, and the hydration of their esters or salts Compounds, preparation methods of these compounds, pharmaceutical compositions containing these compounds, and the use of these compounds for the preparation of drugs for treating and / or preventing infectious diseases belong to the field of medical technology. 2. Background technology [0002] Carbapenems are new broad-spectrum, enzyme-resistant and highly effective β-lactam antibiotics developed in the 1970s. In 1976, Thiamycin, the first carbapenem antibiotic, was discovered, but it was not used clinically due to its poor chemical stability. Later, the chemical structure modification of thiamycin produced a series of carbapenem derivatives. At present, such drugs that have been marketed include imipe...
