Isolation and Structural Determination of Novel Sulfated Hexasaccharides from Squid Cartilage Chondroitin Sulfate E That Exhibits Neuroregulatory Activities

Squid cartilage chondroitin sulfate E (CS-E) exhibits various biological activities, including anticoagulant activities, lymphoid regulatory activities, and neuroregulatory activities [Ueoka, C., Kaneda, N., Okazaki, I., Nadanaka, S., Muramatsu, T., and Sugahara, K. (2000) J. Biol. Chem. 275, 37407-37413]. These activities are expressed through molecular interactions with specific proteins, including heparin cofactor II, selectins, CD44,...
