<p>A sugar derivative which has altered properties of a cyclic tetrasaccharide so as to expand the range of applications of the compound represented by the chemical formula (1); a composition containing the derivative; and a process for producing the derivative. The sugar derivative is obtained by reacting the compound represented by the chemical formula (1) with a reactive reagent to thereby convert one or more of the hydroxy groups into a substituent other than hydroxy and O-glycosyl.</p> |
