Abstract

The invention discloses an HPLC detection method of biapenem side chain related substances. Linear gradient elution is carried out by using octadecylsilane chemically bonded silica as a filler and using a mixed solution of a buffer solution of which the pH value is 3.0-4.5 and an organic solvent as a mobile phase. The detection sensitivity of the detection method provided by the invention is obviously improved compared with that of related substances of the apixem side chain, the separation degree of each impurity and a main peak is very good, and the increase of hydrolyzed impurities can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of antibiotics, in particular to an HPLC detection method for related substances of biapenem side chains. Background technique [0002] The side chain of biapenem belongs to the raw material of medicine and pharmaceutical, which can be used to produce biapenem antibiotic medicine. Biapenem (Biapenem, LJC 10627) is a carbapenem antibiotic for injection developed by Lederle Company of Japan and Cyamide Company of the United States in 1989. It has completed phase III clinical research in Japan and is waiting for approval for marketing. The most notable feature of this product is the 1β-methyl carbapenem with bicyclic triazole on the 2-position S. The study of structure-activity relationship shows that the existence of the side chain quaternary ammonium cationic center is the key to affecting the permeability of the outer membrane, which makes the activity of this product against Pseudomonas aeruginosa and anae...
