Descripción

Descripción general

(2-Hydroxypropyl)-β-cyclodextrin (HP-β-CD) is a beta-cyclodextrin and hydroxyalkyl derivative and is widely used as a chiral solvent, phase transfer catalyst, and host molecule in organic synthesis. HP-β-CD can form inclusion complexes with guest molecules, which can help enhance the solubility, stability, and bioavailability of the guest molecule. It is an alternative to α-, β- and γ-cyclodextrin and exhibits a higher water solubility. HP-β-CD is commonly used as a drug solubilizer. [1]

Aplicación

La solubilidad de los fármacos lipófilos aumenta linealmente con la concentración de hidroxipropil-β-ciclodextrina (HBC) en disolución acuosa debido al complejo entre la HBC y el fármaco. Este complejo tipo huésped-anfitrión se forma entre el fármaco y la cavidad no polar de la HBC que tiene como consecuencia una mayor solubilidad. Las disoluciones pueden liofilizarse para producir polvos libremente solubles. No tóxico en conejos ni ratones.

HP-β-CD can be used:

• As an additive in the separation of amino acids and lactic acids based on the coordination interactions between Cu²⁺ ions and analytes. [2]
• As a chiral selector in capillary electrophoresis, enabling the robust separation of diastereomeric derivatives of aspartic acid for analysis. [3]
• As a reagent to improve water solubility and anti-proliferative activity of pyrazolo[3,4-d] pyrimidines. [4]
• As formulation vehicle. It increases water solubility of the drug for successful delivery of medical agents to a biological system.[1]
• To increase the solubility of ropivacaine (RVC) upon complexation, which in turn enhances the pharmacological activity of RVC.[5]
• To increase the aqueous solubility of naproxen (NAP) in presence of polyvinylpyrrolidone (PVP).[6]
• As a template in the synthesis of hollow spherical copper sulfide nanoparticle assemblies.[7]
