詳細信息(英文):
Gamma-Cyclodextrin (γ-CD) – Overview

γ-Cyclodextrin is a cyclic oligosaccharide composed of eight glucose units linked by α-1,4-glycosidic bonds, produced through the enzymatic action of cyclodextrin glucanotransferase (CGTase) on starch. Its cavity size (diameter ~9.5 ?) is larger than that of α-CD (6 glucose units) and β-CD (7 glucose units), enabling it to encapsulate larger guest molecules (500-1000 Da), such as cholesterol, vitamins, and hormones.

Water solubility: Approximately 23.2 g/100 mL at 25°C (significantly higher than β-CD).

Application features: Ideal for encapsulating macromolecules, improving solubility and stability, with lower hemolytic activity and superior safety.

Basic Information
Chinese Name γ-Cyclodextrin / Cyclooctaose / Cyclomaltooctaose
English Name Gamma-Cyclodextrin; γ-Cyclodextrin; Cyclomaltooctaose; γ-CD
Abbreviation GCD
CAS No. 17465-86-0
Molecular Formula C??H??O??
Molecular Weight 1297.12 g/mol
Characteristics & Advantages
Extra-Large Cavity Structure:

Can encapsulate large hydrophobic molecules (e.g., fat-soluble vitamins, steroidal compounds, anticancer drugs).

Compared to β-CD, exhibits stronger binding affinity for proteins and peptides.

High Water Solubility:

Solubility is 12 times higher than β-CD (1.85 g/100 mL), making it suitable for high-concentration formulations.

Low Toxicity & High Safety:

Significantly lower hemolytic activity than β-CD, making it more suitable for injectable formulations.

Approved by the U.S. FDA for oral and injectable preparations (e.g., Sugammadex, a γ-CD derivative used as an anesthetic reversal agent).

Enhanced Stability:

Protects encapsulated molecules from light, heat, and oxidative degradation, extending shelf life.

Applications
1. Pharmaceutical Field
Solubilization of poorly soluble drugs (e.g., paclitaxel, itraconazole).

Injectable formulations (low hemolytic activity, suitable for IV administration).
