一般描述

γ-环糊精是一种环状低聚糖，含有八个通过α-1,4-糖苷键连接的葡萄糖单元。它可在水溶液中能与各种有机分子形成主客体复合物或包合物。因此，环糊精广泛用于食品和制药行业，用于敏感精细化学品的包合。

应用

γ-环糊精可用作：
  • 催化剂，通过硝酮与苯乙烯和肉桂酸酯的1, 3-偶极子环加成反应合成取代异恶唑烷。
  • 有机配体，通过生物相容性金属离子合成基于环糊精的金属有机框架。
  • 反应物，在存在NaH的条件下，通过烯丙基卤化物的过烯丙基化，合成O-过烯丙基化环糊精。

特点和优势

  • 绿色环保
  • 无生物毒性
  • 可生物降解

A polypseudorotaxane (PPR) comprising γ-cyclodextrin (γ-CD) as host molecules and poly(N-isopropylacrylamide) (PNIPAM) as a guest polymer is prepared via self-assembly in aqueous solution. Due to the bulky pendant isopropylamide group, PNIPAM exhibits size-selectivity toward self-assembly with α-, β-, and γ-CDs.

The synthesis of chitosan-graft-γ-cyclodextrin (Ch-g-γ-CD) using persulfate/ascorbic acid redox system was done and characterized by FTIR, XRD, TGA and SEM/EDX. The optimum yield of the copolymer was obtained using 16×10(-3) M γ-cyclodextrins (γ-CD), 2.8×10(-2) M ascorbic acid (AA), 1.8×10(-2) M

Diamide linked γ-cyclodextrin (γ-CD) dimers are used to capture curcumin and suppress its decomposition in water. In this study, succinamide and urea linked γ-CD dimers joined through the C6(A) carbon on each γ-CD are used. The γ-CD dimers, 66γCD(2)su and

Novel supramolecular hydrogels were formed between pyrene-terminated poly(ethylene glycol) star polymers and γ-cyclodextrin (γ-CD), through the inclusion complexation of dimers of the pyrene terminals with γ-CD, where γ-CD was directly used as a supramolecular cross-linking reagent without any modification.

Although 3α-hydroxy, 5α-reduced pregnane steroids, such as allopregnanolone (AlloP) and tetrahydrodeoxycorticosterone, are endogenous positive modulators of postsynaptic GABA(A) receptors, the functional roles of endogenous neurosteroids in synaptic transmission are still largely unknown. In this study, the effect of AlloP on
