Description

General description

γ-Cyclodextrin is a cyclic oligosaccharide containing eight glucose units linked by α-1,4-glycosidic bonds. It can form host-guest or inclusion complexes in aqueous solutions with various organic molecules. As a result, cyclodextrins are widely used in the food and pharmaceutical industries for the microencapsulation of sensitive fine chemicals.

Application

γ-Cyclodextrin can be used as:

A catalyst to synthesize substituted isoxazolidines via 1,3-dipolar cycloaddition of nitrones with styrenes and cinnamates.
An organic ligand to synthesize cyclodextrin-based metal-organic frameworks using biocompatible metal ions.
A reactant to synthesize O-perallylated cyclodextrins via perallylation with allyl halides in the presence of NaH.

Features and Benefits

Green and environment-friendly
No biological toxicity
Biodegradable

yCD/HPyCD mixtures as solubilizer: solid-state characterization and sample dexamethasone eye drop suspension.

Phatsawee Jansook et al.

Journal of pharmacy & pharmaceutical sciences : a publication of the Canadian Society for Pharmaceutical Sciences, Societe canadienne des sciences pharmaceutiques, 13(3), 336-350 (2010-11-26)

Study the complexation of dexamethasone in combinations of γ-cyclodextrin (γCD) and 2-hydroxypropyl-γ-cyclodextrin (HPγCD) with emphasis on solid characterization and development of aqueous dexamethasone eye drop suspension for drug delivery through sclera. Dexamethasone/cyclodextrin (dexamethasone/CD) solid complex systems were prepared and characterized

Modulation of presynaptic GABA(A) receptors by endogenous neurosteroids.

B-G Kim et al.

British journal of pharmacology, 164(6), 1698-1710 (2011-05-19)

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

Sulfadiazine-selective determination in aquaculture environment: selective potentiometric transduction by neutral or charged ionophores.

S A A Almeida et al.

Talanta, 85(3), 1508-1516 (2011-08-03)

Solid-contact sensors for the selective screening of sulfadiazine (SDZ) in aquaculture waters are reported. Sensor surfaces were made from PVC membranes doped with tetraphenylporphyrin-manganese(III) chloride, α-cyclodextrin, β-cyclodextrin, or γ-cyclodextrin ionophores that were dispersed in plasticizer. Some membranes also presented a
