A Review on Cyclodextrins/Estrogens Inclusion Complexes.

Area of Science:

• Supramolecular Chemistry
• Analytical Chemistry
• Environmental Science

Background:

• Estrogens, due to low polarity, form inclusion complexes with cyclodextrins (CDs) via hydrophobic interactions.
• These estrogen-cyclodextrin complexes have been utilized for over 40 years in diverse applications.
• Cyclodextrins offer a means to modify the properties of estrogens for specific uses.

Purpose of the Study:

• To review the preparation methods for estrogen-cyclodextrin inclusion complexes.
• To summarize the biological, physicochemical, and theoretical analyses of these complexes.
• To consolidate key findings on the synthesis and application of estrogen-CD complexes.

Main Methods:

• Review of literature on synthesis and characterization of estrogen-CD complexes.
• Analysis of in silico, in vitro, and in vivo studies.
• Examination of applications in pharmaceuticals, separation sciences, and environmental remediation.

Main Results:

• Estrogen-CD complex formation depends on geometric compatibility and cyclodextrin cavity properties.
• Applications include enhanced drug solubility and absorption, separation techniques, and pollutant removal.
• Complexation aids in sample preparation for analytical methods like mass spectrometry.

Conclusions:

• Estrogen-cyclodextrin complexation is a robust strategy with broad applicability.
• Further research can optimize complex formation for targeted pharmaceutical and environmental solutions.
• This review highlights the significance of estrogen-CD interactions in various scientific domains.
