Heptakis(2,6-di-O-ethyl)-beta-cyclodextrin (DE-beta-CyD) was prepared and its 1H and 13C nuclear magnetic resonance (NMR) signals in DMSO-d6 were unequivocally assigned by two-dimensional COSY and ROESY. The results on 1H coupling constants indicated that all ethylated glucose units are in a 4C1

Journal of pharmaceutical sciences, 77(3), 233-236 (1988-03-01)
Heptakis(2,6-di-O-ethyl)-beta-cyclodextrin (2) was prepared and its physicochemical properties, such as aqueous solubility and surface activity, were compared with those of beta-cyclodextrin (1) and heptakis(2,6-di-O-methyl)-beta-cyclodextrin (3). A possible utility of 2 as a sustained-release drug carrier was examined using a water-soluble

Drug design and delivery, 6(4), 297-310 (1990-10-01)
The complex-forming abilities of 2,6-di-O-ethyl-beta-cyclodextrin (DE-beta-CD), and its effect on the release of nitroglycerin (TNG) from formulations of the compound, were studied and compared with corresponding properties of beta-cyclodextrin (beta-CD) and 2,6-di-O-methyl-beta-cyclodextrin (DM-beta-CD). Complex formation was confirmed by differential scanning

Carbohydrate research, 329(3), 597-607 (2000-12-29)
Heptakis(2,6-di-O-ethyl)-beta-cyclodextrin (DE-beta-CD) was crystallized in two forms from hexane and 95% aqueous methanol, respectively: A form I crystal with the space group P2(1)2(1)2(1) and a form II crystal with the space group P3(1). In both crystals, DE-beta-CD molecules are in
