Description générale

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin is a β-cyclodextrin derivative that finds potential use in pharmaceutical, food and cosmetic applications. Its attractive features include: the non-polar cavity desirable for its use as a molecular host for a wide range of molecules and its affinity for organic compounds in solution as well as crystalline phases.

Application

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin may be used:
  • To investigate the crystal structure of its complexes with m-iodophenol, 4-biphenylacetic acid and (R)- and (S)-flurbiprofen by X-ray analysis.
  • To study the candidature of its complex with vitamin A for potential application as a drug delivery system for ophthalmic applications by high sensitivity fluorescence spectrometry and high pressure liquid chromatography (HPLC).
  • In the determination of analyte composition in commercial samples by HPLC coupled to mass spectrometry (MS).

Chiral additive in liquid chromatography for enantiomer resolution. Chiral separation of basic drug substances by capillary electrophoresis.

The enantiomeric separation of gemfibrozil chiral analogues was performed by capillary zone electrophoresis (CZE). Resolution of the enantiomers was achieved using heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM-beta-CD) as chiral selector dissolved into a buffer solution. In order to optimize the separation conditions, type, pH
