Superstructures with cyclodextrins: Chemistry and applications IV
Cyclodextrins (CDs) are of increasing scientific and commercial interest because they are readily available, harmless and well-defined, forming sophisticated supramolecular structures in aqueous media. More than 2,300 publications and more than 1,200 patents appeared in 2015 in which CDs played a significant role. As exemplified in the following, CD chemistry has developed into a very attractiv...
متن کاملSuperstructures with cyclodextrins: Chemistry and applications
Since their discovery more than 100 years ago, a significant development in CD research has taken place. Right after their discovery, CDs were very expensive due to the fact that only small quantities were available. In addition to this, it was assumed that CDs are toxic to human beings. Meanwhile, things have changed. Now, large quantities of CDs are available at low prices. Additionally, it c...
متن کاملAdvances in physical chemistry and pharmaceutical applications of cyclodextrins*
Cyclodextrins (CDs) attract much attention for industrial applications and academic research. A few experimental methods for determination of the binding constant between CD and a guest molecule were reviewed critically. A hydrophile–hydrophobe matching model for host–guest docking was proposed for estimation of the binding constant and the solution structure of the complex. Rather detailed sol...
متن کاملInteraction of modified cyclodextrins with cytochrome P-450.
The effects of modified cyclodextrins (CDs) hydroxypropyl-beta-CD and methyl-beta-CD were studied in vitro on cDNA-expressed human cytochrome P-450 (CYP) activities (CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4). The modified CDs inhibited the activities of CYP2C19 and CYP3A4 while enhancing CYP2C9 activity by 140 to 176% relative to the control values at lower concentrations. In addition, methy...
متن کاملInclusion complexes of trihexyphenidyl with natural and modified cyclodextrins
The solubility of trihexyphenidyl (Thp) was improved by its combination with β-cyclodextrin (β-CD) and modified β-CDs. The solubility of Thp was found to be increased in the presence of β-CD, hydroxypropyl-β-cyclodextrin (HP-β-CD), methyl-β-cyclodextrin (Me-β-CD) and sulfobutylether-β-cyclodextrin (SBE-β-CD). In particular, the solubility of Thp in conjunction with SBE-β-CD was increased by a f...
