ReviewCyclodextrins and their uses: a review
Section snippets
History
Cyclodextrins are cyclic oligosaccharides consisting of six α-cyclodextrin, seven β-cyclodextrin, eight γ-cyclodextrin or more glucopyranose units linked by α-(1,4) bonds (Fig. 1). They are also known as cycloamyloses, cyclomaltoses and Schardinger dextrins [1], [2]. They are produced as a result of intramolecular transglycosylation reaction from degradation of starch by cyclodextrin glucanotransferase (CGTase) enzyme [3].
They were first discovered in 1891 [1], when in addition to reducing
Properties
Cyclodextrins are of three types: α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin, referred to as first generation or parent cyclodextrins. α-, β- and γ-cyclodextrins are composed of six, seven and eight α-(1,4)-linked glycosyl units, respectively [15]. β-Cyclodextrin is the most accessible, the lowest-priced and generally the most useful. The main properties of those cyclodextrins are given in Table 1.
Studies of cyclodextrins in solution are supported by a large number of crystal structure
Conclusions
Many types of encapsulation are available which coat a fine particle of an active core with an outer shell. Encapsulation also can occur on a molecular level. This can be accomplished using a category of carbohydrates called CDs, encapsulates made with these molecules may possibly hold the key for many future encapsulated formulation solutions.
The ability of cyclodextrins to form inclusion complexes with many guest molecules by taking up a whole molecule, or some part of it, into the cavity
