Article Description

Sulfated β-(1→4)-galacto-oligosaccharides were prepared from an arabino-galacto-rhamno-galacturonan from Lupinus polyphyllus Lindl. by successive partial hydrolysis and SO 3 –pyridine sulfation in DMF. The resulting oligosaccharide polysulfates were analyzed by analytical GPC and the sulfate content was determined by ion chromatography. DP 5 and higher showed a pronounced antiangiogenic effect with scores of 0.9–1.2 for DP 7–9 using the CAM-assay. An interaction with the fibroblast growth factor FGF-2 was noticed for DP 4–12 depending on the degree of sulfation using the FGF-2-trypsin assay.
