Inclusion complexation between celecoxib, a specific cyclooxygenase II inhibitor, and beta-cyclodextrin (b-CD) was studied in solution and solid state. Drug cyclodextrin complexes were prepared by spray drying while physical mixtures were obtained by simple blending. Inclusion complexes were charact

Apparent molar heat capacities C p,φ and apparent molar volumes V φ were determined for aqueous solutions of αand β-cyclodextrins at temperatures from 278.15 K to 393.15 K and at the pressure 0.35 MPa. The molalities investigated ranged from 0.008 mol • kg -1 to 0.12 mol • kg -1 for α-cyclodextrin a
Complete analyses of the proton and carbon chemical-shift assignments of D-mannurono-y-lactone (1) have been achieved by 1D and 2D NMR spectral measurements. At equilibrium, the anomeric LY and p forms were present in the ratio of 34:66 in D,O and 72:28 in Me,SO-d,. The solution data indicated tha
