Preparation and characterization of 6A-polyamine-mono-substituted β-cyclodextrins

, p. 3157 - 3160 (1997)
General syntheses for eleven β-cyclodextrins (cyclomaltoheptaoses) mono-substituted at the C6 position by a polyamine are described. The basis of the synthesis is the reaction of 6A-O-(4-methylphenylsulfonyl)-β-cyclodextrin in the presence of KI in 1-methylpyrrolidin-2-one solution. This produces a clean product and obviates the substantial purification procedures which other preparative methods often entail. Systematic studies of the variations of the P-KaS of the protonated amine groups and the 13C NMR spectra of the modified β-cyclodextrins with pH are reported.

A modified cyclomaltoheptaose (β-cyclodextrin) containing an anthraquinone moiety, mono[6-deoxy-N-n-hexylamino-(N′-1-anthraquinone)]- β-cyclodextrin (1), which can self-assemble into nanorods in aqueous solution, was synthesized. Interestingly, upon the a
Reversible 2D pseudopolyrotaxanes based on cyclodextrins and cucurbit[6]uril

, p. 280 - 283 (2007)
In this paper, a pseudorotaxane (2) was synthesized by reaction of cucurbit [6]uril with 6-[(6-aminohexyl)amino]-6-deoxy-β-cyclodextrin chloride. Subsequently, pseudorotaxanes 2 were further assembled to form a 2D pseudopolyrotaxane (3) through an α,ω-PPG2000 diamino polymer threading the cavities of cyclodextrins in 2, and the resulting pseudopolyrotaxane was comprehensively characterized by FT-IR, NMR, TG-DTA, elemental analysis, and transmission electron microscopy. Significantly, the 2D pseudopolyrotaxane can turn into a main-chain pseudopolyrotaxane in the presence of base, and then the addition of α-cyclodextrins may result in a reversible switch between two different 2D pseudopolyrotaxanes.

Paragraph 0039; 0057-0059, (2020/04/02)
The invention discloses application of a functional carrier based on alkylamino cyclodextrin in entrapment of ferulic acid. On the one hand, alkylamino-modified beta-cyclodextrin is designed as a mainbody to prepare a ferulic acid clathrate compound; and on the other hand, an alkylamino cyclodextrin high-molecular polymer connected with linear polymer molecules is designed to load ferulic acid. Compared with the ferulic acid monomer, the ferulic acid entrapped by the carrier has advantages that the water solubility is obviously improved and the thermal stability is also enhanced; and a certain theoretical reference is provided for developing a novel water-soluble ferulic acid material and expanding the application of ferulic acid in the field of food and medicine.
