β-Cyclodextrin 10.41-hydrate
The crystal structure of β-cyclo-dextrin, C(42)H(70)O(35)·10.41H(2)O, consists of truncated cone-shaped β-cyclo-dextrin mol-ecules that are herringbone packed. The primary hydr-oxy groups form an intra-molecular hydrogen-bonded array. The semipolar cavity of the cyclo-dextrin host is filled with water mol-ecules, which show partial occupancy and disorder.
متن کاملNovel β-cyclodextrin–eosin conjugates
Eosin B (EoB) and eosin Y (EoY), two xanthene dye derivatives with photosensitizing ability were prepared in high purity through an improved synthetic route. The dyes were grafted to a 6-monoamino-β-cyclodextrin scaffold under mild reaction conditions through a stable amide linkage using the coupling agent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride. The molecular conjuga...

متن کاملEncapsulation Mechanism of Oxyresveratrol by β-Cyclodextrin and Hydroxypropyl-β-Cyclodextrin and Computational Analysis.
In this study, the encapsulation mechanism of oxyresveratrol and β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) was studied. As this research shows, oxyresveratrol and two cyclodextrins (CDs) were able to form inclusion complexes in a 1:1 stoichiometry. However, the interaction with HP-β-CD was more efficient, showing up as higher encapsulation constant (KF) (35,864.72 ± 3415....
متن کاملPhase Solubility Studies on Oral Antidiabetic Drugs with Β-cyclodextrin and Hp - Β Cyclodextrin
Nateglinide(NTG), Repaglinide(RPG), and Glimepiride(GMP) are antidiabetic drugs. These antidiabetic drugs are poorly soluble in water, which affect the bioavailability. In the present work, complex formation of all the three drugs with b-cyclodextrin (b-CD) and Hydroxy propyl bcyclodextrin (HPb-CD) and then the possibility of improving the solubility of NTG, RPG and GMP by complexation with b-C...
