摘要： Methods for preparing a glycopeptide are disclosed. The methods comprise the steps of selecting a protected glycopeptide of the formula A1-A2-A3-A4-A5-A6-A7, wherein the groups A1 to A7 comprise the heptapeptide structure of naturally occurring vancomycin; at least A4 is linked to a glycosidic group which has a hexose residue linked to A4; and the protected glycopeptide has no free amino or carboxyl groups and has a free primary hydroxyl group only at the 6-position of said hexose residue. The protected glycopeptide is contacted with a compound of the formula ArSO2G where Ar is an aryl group and G is a leaving group under conditions effective to allow reaction of said free primary hydroxyl group to form a glycopeptide sulfonate ester; and the glycopeptide sulfonate ester is contacted with a nucleophile under conditions effective to allow displacement of a sulfonate group to produce a substituted glycopeptide.

摘要： A simple and efficient method of preparing a sample in the measurement according to matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) capable of inhibiting any ion suppression by impurities, such as inorganic salts and surfactants, contained in the sample. An analyte and matrix molecules are co-crystallized in the presence of porous microparticles. Preferably, this co-crystallization is carried out by bringing the analyte, matrix molecules and porous microparticles into contact with each other on a target plate and thereafter drying the mixture. The porous microparticles consist of an ion exchanger having an average particle diameter of not more than 50 μm, preferably a strongly basic anion exchanger.
