Descripción general

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.

Aplicación

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

EPR spectroscopy has been employed to investigate the formation of complexes between heptakis-(2,6-O-dimethyl)-beta-cyclodextrin (DM-beta-CD) and different enantiomeric pairs of chiral nitroxides of general structure PhCH2NO.CH(R)R'. Accurate equilibrium measurements of the concentrations of free and included radicals afforded the binding constant

The transport of alendronate through Caco-2 monolayers in the absence and presence of absorption enhancers (sodium taurocholate-STC and dimethyl-beta-cyclodextrin-DM-beta-CD) was studied. The viability of Caco-2 cells was determined by MTT assay. The effects of the experiment period and serum existence

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
