摘要

LaPSvS1,a highly sulfated branached (1-3)-beta-galactan was prepared from the arabino-galactan from Larix decidua Miller by partial hydrolysis and subsequent sulfation with SO_3-pyridine in DMF.The molecualr weight was analyzed by GPC and the sulfate content was determined by ion chromatography.LaPSvS1 exhibited good antiangiogenic and antiinflammarotry effects in two different modifications of the known CAM-assay.In vitroresults obtained inthe FGF-2trypsin-assay and in fluorospectrometric experiments revealed that LaPSvS1 interacts with the fibroblast growth factor 2 system.This interaction is correlated with the in vivo effect of LaPSvS1 on FGF-2 induced angiogenesis.
