    摘要: A therapeutic composition includes a polysaccharide, isolated from a member of the genus Cucurbita , e.g., pumpkin, having a backbone including alternating α-L-rhamnosyl (α-L-Rha p ) and α-D-galactopyranosyluronic acid (α-D-Gal p A) residues, and a side chain attached to the backbone including β-D-galactan (β-D-Gal p ), α-L-arabinofuranosyl (α-L-Ara f ), or combinations thereof, and a pharmaceutically acceptable excipient. A β-D-Galp side chain is attached to the backbone at the C-4 carbon of at least one α-L-Rhap of the backbone. At least one α-L-Araf is attached to the β-D-Galp side chain. The a-L-Araf is attached to the β-D-Galp side chain via the C-3 carbon of the β-D-Galp. The polysaccharide is effective for treating a galectin-3 dependent disorder by binding to the carbohydrate recognition domain of galectin-3, resulting in inhibition of galectin-3 activity.
