Organoselenium Compounds: Chemistry and Applications in Organic Synthesis.

Area of Science:

• Organometallic Chemistry
• Medicinal Chemistry
• Biochemistry

Background:

• Selenium, initially recognized as a toxin, is now understood as a vital trace element in biological systems, existing as selenocysteine and selenocystine.
• Selenium compounds are explored as isosteres for sulfur and oxygen in drug design, offering unique properties.

Purpose of the Study:

• To review the synthetic strategies for creating diverse organoselenium molecules.
• To discuss the biological properties and potential applications of selenium-containing compounds in medicine.

Main Methods:

• Exploration of synthetic methodologies for organoselenium compound preparation.
• Review of literature on the biological activities and drug development potential of selenium derivatives.

Main Results:

• Organoselenium compounds exhibit antioxidant properties and high lipophilicity, enhancing cell membrane permeability and oral bioavailability.
• Various selenium-containing molecules, such as selenosugars (selenoglycosides, selenonucleosides) and selenopeptides, have been synthesized and studied.

Conclusions:

• Selenium's unique chemical properties make it a valuable element for developing novel therapeutic agents.
• Organoselenium chemistry provides promising avenues for enhancing drug efficacy and delivery through improved bioavailability.
