Application

(2-Hydroxypropyl)-γ-cyclodextrin has been used to study its inhibitory effect on complement products and the inflammation induced by cholesterol crystals (CCs) from plasma samples.

Biochem/physiol Actions

(2-Hydroxypropyl)-γ-cyclodextrin (HPγCD) is a water-soluble alkylated cyclodextrin derivative. It has pharmaceutical potential as it may aid in enhancing the solubility of drugs for oral dosage preparations or formulations. It solubilizes macromolecules, such as cholesterol. It is like β cyclodextrin but solubilizes larger molecules. It favors lysosomes distribution across the cytoplasm and can modulate lysosomal dynamics and participates in lysosomal homeostasis. In the Niemann pick disease model, HPγCD reduces cholesterol accumulation.

Other Notes

Non-toxic solubilizer. γ-Cyclodextrin (8-glucose units) has a slightly larger cavity and can accommodate larger substrates than β-cyclodextrin.

Cyclodextrins

Many metabolically important compounds, such as lipid-soluble vitamins and hormones, have very low solubilities in aqueous solutions. Various techniques have been used to solubilize these compounds in tissue culture, cell culture, or other water-based applications.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
