[Effect of carbohydrate components of ristomycin A on platelet aggregation in human plasma]

In the process of the investigation, conditions for specific removal of arabinose in tetrasaccharide of ristomycin A, a glycopeptide antibiotic as well as conditions for simultaneous removal of arabinose and mannose-2 bound to actinoidinic acid were determined. The role of arabinose in manifestation of the ristomycin A ability to induce platelet aggregation was shown to be important. Mannose-2 also had the same ability while its level was somewhat lower.
