Scientific Research Special Cyclodextrin Reagent mainly including Oligo Beta Cyclodextrin, Mono-6-Azido-6-Deoxy Beta Cyclodextrin, Mono Hexamethylenediamine Beta Cyclodextrin, Mono-6-Ethanediamine-6-Deoxy Beta Cyclodextrin, Mono-6-p-Toluenesulfonyl Beta Cyclodextrin, Polyethylene Polyamine Modified Beta Cyclodextri,mono azido beta cyclodextrin cas 98169-85-8,Oligo Beta Cyclodextrin cas 98169-85-8.
Oligo (lactic acid) -beta-cyclodextrin (OLA-B-CD) is a new cyclodextrin derivative. Oligo-(lactic acid) group that can be degraded in the human body modified cyclodextrin with the general characteristics of common cyclodextrin derivatives, also has unique properties: 1, excellent biocompatibility. 2, excellent controlled release of specific guest molecular. 3, adjustable water-solubility. 4, capability to form duel interactions with specific drugs [1].
OLA-β-CD can be used to improve the solubility of water insoluble drugs, enhance drug stability and bioavailability, and achieve controlled release system or delayed release system of drugs. OLA-β-CD is of immense value in the field of drug development.
Features and use of Mono-6-Ethanediamine-6-Deoxy Beta Cyclodextrin:
Organic amine groups in a neutral or acid conditions can be positively charged which have very good composite ability to guest molecules.
Diamine group can form complex with many metal ions , such as Cu2+,Cr3+,Mg2+ and so on. This provide new approachs to achieve artifical enzyme and highlight supramolecular researches.
Diamine also provide a secondary amine group and a primary amine group which can be linked to many functional group. This make diamine cyclodextrin an important intermediate for cyclodextrin synthsis.
