General description

Heptakis(2,6-di-O-methyl)-β-cyclodextrin is a hydrophilic derivative of cyclodextrin that possesses the ability to effectively dissolve lipophilic drugs like steroid hormones, vitamins A, E, and K, etc. It can be utilized to increase the dissolution and bioavailability of weakly water-soluble pharmaceutical compounds.

Application

Heptakis(2,6-di-O-methyl)-β-cyclodextrin may be used:
  • To measure the equilibrium constant of its complexes with various enantiomeric pairs of chiral nitroxides by electron paramagnetic resonance (EPR) spectroscopy.
  • To study the crystal structure of its complex with n-butyl acrylate and isobornyl acrylate using X-ray diffraction (XRD).
  • As a chiral selector to resolve amphetamine related drugs by capillary zone electrophoresis.

Reactant involved in:
  • Physicochemical studies of inclusion complexes
  • Probing diffusion and single molecule interactions with reconstituted membrane proteins
  • Interactions with micelles causing micellar rupture
  • Studying cellular transport, used as a cell penetration enhancer
  • Physicochemical and biopharmaceutical improvement of drugs particularly with solubilization and stability
  • Interactions with cholesterol

Quality

Impurities are over-methylated homologs, primarily hexakis(2,6-di-O-methyl)-(2,3,6-tri-O-methyl)-β-cyclodextrin.

Acetyl groups were introduced to the hydroxyl groups of heptakis(2, 6-di-O-methyl)-beta-cyclodextrin (DM-beta-CyD), and the resulting heptakis(2,6-di-O-methyl-3-O-acetyl)-beta-CyD (DMA-beta-CyD) was evaluated for the inclusion property and hemolytic activity. It was confirmed by means of NMR and mass spectroscopies that in the DMA-beta-CyD

Four different 5-nitroindazole derivatives (1-4) and its inclusion with Heptakis(2,6-di-O-methyl)-beta-cyclodextrin (DMbetaCD) were investigated. The stoichiometric ratios and stability constants describing the extent of formation of the complexes were determined by phase-solubility measurements obtaining in all cases a type-A(L) diagram. Also
