Mannan is a polysaccharide that is widely distributed from higher plants to microorganisms. In recent years, research on their chemical structures has progressed, and structural formulas of several repeating units have been proposed. For example, yeast mannan and potato mannan are proteomannans that exist on the surface of cells (T. Nakajima, H.
Sasaki, M.Sato, K.Tamari and K.Matsuda,
J.Biochem. (Tokyo) 82, 1657-1662) A complex branched structure is considered. Since these mannans exist on the surface layer, it is highly likely that they are also involved in recognition phenomena between organisms. Furthermore, antitumor activity has been reported for some mannans. The present inventors are conducting research on the synthesis of oligomannosides having accurate structures, with the aim of elucidating the correlation between these biological functions, antitumor activities, and mannan structure.
