title: Synthesis of mono-glucose-branched cyclodextrins with a high inclusion ability for doxorubicin and their efficient glycosylation using Mucor hiemalis endo-beta-N-acetylglucosaminidase.
abstract: The mono-glucose-branched cyclodextrins having an appropriate spacer between the beta-cyclodextrin and a glucose moiety were synthesized from beta-cyclodextrin and arbutin. They had the significantly high association constants for doxorubicin, the anticancer agent, in the range of 10(5)-10(6)M(-1), and worked as highly reactive glycosyl acceptors for the transglycosylation reaction by endo-beta-N-acetylglucosaminidase of Mucor hiemalis to produce sialo-complex type oligosaccharide-branched cyclodextrins in the high yields of 65-67%.
