- A raw meluopeinan, method for preparing the same and pharmaceutical composition containing the same
-
The invention discloses a meropenem raw medicine which is characterized in that the content of meropenem in the raw medicine is 98.0-101.0% by weight based on anhydride; the content of the impurity A and impurity B in the related substances of the raw medicine is not greater than 0.25% respectively; the content of any unknown single impurity is not greater than 0.05%; the total content of other impurities except the A and B is not greater than 0.2%; the acetone residue is not greater than 500ppm. The invention also discloses a meropenem pharmaceutical composition for injection, and the pharmaceutical composition takes the meropenem raw medicine provided by the invention as an active ingredient and has excellent stability. The meropenem raw medicine provided by the invention has the advantages of high purity, clear impurity condition, low solvent residue, good solubility and good long-term storage stability, and can guarantee the effectiveness and safety of the medicine. In the invention, the process is simple and compact, the cost is remarkably low, and the control is simple. The invention is suitable for industrial large-scale aseptic production of the meropenem raw medicine and pharmaceutical preparation.

- IMPROVED PROCESS FOR PRODUCING CARBAPENEM COMPOUND
-
The present invention has its object to provide an easy process for producing (4R,5S,6S)-3-[[(3S,5S)-5-(dimethylaminocarbonyl)-3-pyrrolid inyl]thio]-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-1-azabicy clo[3.2.0]hept-2-ene-2-carboxylic acid, excellent in antimicrobial activity. The present invention relates to a process for continuously producing (4R,5S,6S)-3-[[(3S,5S)-5-(dimethylaminocarbonyl)-3-pyrrolid inyl]thio]-6-[(1R)-1-hydroxyethyl]-4-methyl-7-oxo-1-azabicy clo[3.2.0]hept-2-ene-2-carboxylic acid without isolating/purifying the reaction intermediate.
