Biological Activity

SBE-β-CD (Sulfobutylether beta-cyclodextrin) is a unique reproducible mixture of polyanionic β-cyclodextrin derivatives in which a sodium sulfonate salt is tethered to the lipophilic cyclodextrin cavity by a butyl ether group, or sulfobutylether (SBE). The sulfobutyl ether (SBE) substituent is introduced at the 2, 3, and 6 positions in one or more of the glucopyranose units in the cyclodextrin structure.
