Description
Technical Field
The invention relates to the field of pharmaceutical analysis, in particular to a bivalirudin raw material and a quality control method of a bivalirudin preparation.
Background
Bivalirudin (CAS No.: 128270-60-0, molecular formula: C)98H138N24O33Molecular weight: 2180.29) is a synthetic hirudin analogue consisting of 20 amino acid residues which directly inhibits thrombin activity, recognizes the binding site of thrombin and fibrinogen and thereby inhibits thrombin activity. At present, no quality control method for bivalirudin raw materials and preparations thereof is reported, and the establishment of a stable and reliable quality control method for the raw materials and the preparations thereof has great significance.
The difference of polypeptide chain constitution directly influences the establishment of the detection method, and at present, the polypeptide detection method comprises High Performance Liquid Chromatography (HPLC), Mass Spectrometry (MS), liquid chromatography-mass spectrometry (LC-MS), capillary electrophoresis-mass spectrometry (CE-MS), spectroscopic analysis and the like. When a polypeptide is detected by High Performance Liquid Chromatography (HPLC), the following problems exist: (1) the detection of the polypeptide has higher requirements on the composition and the pH value of a mobile phase; (2) the separation degree can not meet the requirement; (3) the polypeptide is readily adsorbed to the filler.
For example, in the currently disclosed method for measuring related substances and contents in the bivalirudin quality standard for injection with the drug standard number YBH01662016, 0.1mol/L sodium acetate buffer (8.2 g of anhydrous sodium acetate is taken and about 900ml of water is added for dissolution, the pH value is adjusted to 6.5 by acetic acid, the solution is diluted to 1000ml) by adding water to form a mobile phase A by using water (50: 50), and 0.1mol/L sodium acetate buffer-acetonitrile (50: 50) to form a mobile phase B by using the following table for gradient elution, wherein the flow rate is 1.2ml/min, the column temperature is 40 ℃, and the detection wavelength is 215 nm. Tests prove that the mobile phase of the enterprise has the following defects: (1) after the mobile phase is used for multiple times, the chromatographic column is damaged, the column efficiency is low, the service life of the chromatographic column is shortened, the scientific research cost is increased, and (2) the content determination is inconsistent with the liquid phase determination method of related substances, and different mobile phases are used for detecting related substance impurities I, II and III, the operation is complicated, the calculation is complex, and (3) only three impurities are detected in the standard, but the determination method of other two impurities is not seen, namely the related substance detection is incomplete.
Through literature search, there is also a report on the determination of 6 related substances in bivalirudin for injection by gradient elution using high performance liquid chromatography, a column YMC-Pack ODS-AM (250 mm. times.4.6 mm, 5 μm) using octadecylsilane chemically bonded silica as a packing material, a column temperature of 30 ℃, a wavelength of 210nm, a sample size of 20 μ L, a phosphate solution of 5mmol/L (pH adjusted to 3.5 with phosphoric acid) as a mobile phase A, and acetonitrile as a mobile phase B, as seen from the chromatogram. It has also been reported that the content of veratridine and related substances was measured using Diamonsil C18 column (250 mm. times.4.6 mm, 5 μm), 5mmol/L potassium dihydrogen phosphate (pH adjusted to 2.5 with phosphoric acid solution) and acetonitrile (80: 20) as mobile phase at a flow rate of 1mL/min and a detection wavelength of 210 nm. After rechecking, the method still has the problem that the chromatographic column is damaged after the mobile phase is used for many times, so that the column efficiency is low, the service life of the chromatographic column is shortened, and the scientific research cost is increased.
Therefore, it is of great significance to provide a method which can accurately evaluate the quality of a raw material of vardendine and a preparation thereof and can prolong the service life of a chromatographic column.
