Fig. 2. (A) Truncated cone shape of β-CD-DA and position of its different protons. The hydrophobic cavity of β-CD-DA is lined with H-3′ and H-5′ protons and their NMR signals are more influenced than those of the other β-CD-DA protons (H-1′, 2′, 4′, 6′); (B) chemical structure of OFLX; (C) the 2D 1H NMR ROESY partial counter plot spectra of β-CD-DA/OFLX inclusion complex in D2O at 298 K.
