일반 설명

2-Hydroxypropyl-β-cyclodextrin is a cyclic oligosaccharide and used as a pharmaceutical excipient to improve the stability and bioavailability of drugs.

(2-Hydroxypropyl)-β-cyclodextrin, a hydroxyalkyl derivative, is mainly used as a formulation vehicle to increase the dissolution of drugs in water for the successful delivery of medicinal agents to biological systems. It is commonly utilized as a substitute for α-, β- and γ-cyclodextrins.

애플리케이션

(2-Hydroxypropyl)-β-cyclodextrin may be used:
  • As an analytical standard for the determination of the analyte in pharmaceutical formulations as well as nanoparticle formulations by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC), respectively.
  • To study the host-guest interaction with organic low molecular mass compounds prior to their quantification using reversed phase HPLC technique.
  • As a mobile phase additive for the effective separation of β-carbolines by HPLC.
  • In cyclodextrin-modified micellar electrokinetic chromatography (CD-modified MEKC) for the determination of sertraline hydrochloride and the synthesis-related products.
  • As a chiral selector to resolve pantothenic acid by capillary electrophoresis.

The solubility of lipophilic drugs increases linearly with the concentration of hydroxypropyl-β-cyclodextrin (HBC) in aqueous solution because of the complex between HBC and the drug. This guest-host type complex is formed between the drug and the non-polar cavity in the HBC that results in enhanced solubility. Solutions may be lyophilized to produce freely soluble powders. Non-toxic in rabbits and mice.

A rapid and simple HPLC method with evaporative scattering detection (ELSD) has been developed for the separation and quantitation of beta-cyclodextrin (beta-CD), 2-hydroxypropyl-beta-cyclodextrin (2-HP-beta-CD) and poly(methyl vinyl ether-co-maleic anhydride) (Gantrez). Separation was carried out on a Zorbax Eclipse XDB-Phenyl narrow

In this work development, optimization and validation of a cyclodextrin-modified micellar electrokinetic chromatography (CD-modified MEKC) method is proposed to resolve separation of the sertraline hydrochloride and synthesis-related substances. Sertraline hydrochloride, the cis-(1S,4S) enantiomer form, is used as an antidepressant therapeutic
