Spectrophotometric study of fluorescence sensing and selective binding of biochemical substrates by 2,2'-bridged Bis(beta-cyclodextrin) and its water-soluble fullerene conjugate
Article Abstract:
A bis(beta-cyclodextrin)- fullerene conjugate linked at the secondary hydroxyl side is prepared in a good yield from its precursor N.N-bis(2-(2-aminoethylamino)ethyl)malonamide-bridged bis(beta-cyclodextrin). The spectrophotometric study of fluorescence sensing and circular dichroism spectroscopy showed that the bis(beta-cyclodextrin)-fullerene conjugate displayed an intramolecular capsulate-type conformation in aqueous solution.

Molecular recognition thermodynamics of bile salts by beta-cyclodextrin dimers: Factors governing the cooperative binding of cyclodextrin dimers
Article Abstract:
The complex stability constants, standard molar enthalpy, and entropy changes for the inclusion complexation of two families of beta-cyclodextrin (beta-CD) dimers, with four bile salt guests, were determined at 25 degree Celsius in Tris buffer solution at 298.15 K by means of isothermal titration microcalorimetry. The bile salt guests used included sodium cholate and sodium glycocholate.
