New lamellar structure formed by an adamantyl derivative of cholic acid
Article Abstract:
The self-aggregation of the sodium salt of a new adamantyl amide of the 3[beta]-amino derivative of cholic acid is aqueous solution is examined by surface tension, dynamic light scattering, fluorescence, small-angle X-ray scattering and transmission electron microscopy measurements. The adamantyl moieties reside in the central region of the bilayer and the structure is open enough to allow water molecules to interact with a fluorescence probe located at the central hydrophobic region.

Complexation of adamantyl compounds by beta-cyclodextrin and monoaminoderivatives
Article Abstract:
The inclusion processes of two 1- substituted adamantly derivates (rimantidine and adamantylmethanol) with beta-cyclodextrin and its two-monoamino derivates at position 6 (6-NH2beta-CD) and 3 (3-NH2beta-CD) were studied. The findings state that the difference in the free energy for the formation of the two complexes c(sub s) and (sub p) for the host/guest system were estimated.

pH Dependent in-out isomerism of an amino-[beta]-cyclodextrin derivative
Article Abstract:
The amino derivative of [beta]-cyclodextrin is compounded and the formation of an intramolecular inclusion complex is explored by NMR techniques. The deprotonation/protonation of the amino group stimulates an in/out movement of the pendant side chain toward/from the cyclodextrin cavity.
