摘要
beta -Glucans are polysaccharides that act as nonspecific immune system stimulants. However, many beta -Glucans are sparingly soluble in water. This work describes an oxidative procedure, which solubilizes the beta -Glucan from Saccharomyces cerevisiae and maintains its immunostimulatory properties. Furthermore, the carboxylates at the site of oxidation allow for the conjugation of small molecule immunostimulants. Both the parent oxidized beta -glucan and its conjugates with O-beta -alanyl-5-[6-(N, N'-dimethylamino)purin-9-yl]pentanol stimulate cytotoxic T-lymphocytes (CTLs), B cells acid macrophages. In addition, they both stimulate natural killer (NK) cells, a property which the small molecule purine does not possess. (C) 2001 Elsevier Science B.V. All rights reserved.
