In the world of chemistry, cyclodextrins have emerged as fascinating molecular entities with a wide array of applications spanning pharmaceuticals, food, cosmetics, agriculture, and beyond. These cyclic oligosaccharides possess a unique structural architecture that bestows upon them remarkable properties, making them indispensable in various fields of science and industry. This article aims to delve deep into the realm of cyclodextrins, elucidating their structure, properties, synthesis methods, and diverse applications. These cyclic structures exhibit a hydrophilic exterior and a hydrophobic cavity, which imparts them with exceptional host-guest complexation capabilities. The structure of cyclodextrins plays a pivotal role in dictating their properties and applications. The hydrophobic cavity formed within the cyclic structure enables the encapsulation of guest molecules through non-covalent interactions such as hydrogen bonding, hydrophobic interactions, and van der Waals forces. This unique property allows cyclodextrins to form inclusion complexes with various guest molecules, ranging from small hydrophobic compounds to large biomolecules like proteins and nucleic acids. Moreover, cyclodextrins are biocompatible, non-toxic, and biodegradable, making them suitable for a myriad of applications in pharmaceuticals, food, and other industries. Their ability to improve the solubility, stability, and bioavailability of poorly soluble drugs has garnered significant attention in the pharmaceutical sector. Additionally, cyclodextrins exhibit chiral recognition capabilities, making them valuable tools in chromatography and separation science. The synthesis of cyclodextrins predominantly involves enzymatic or chemical methods. Enzymatic synthesis, employing Cyclodextrin Glucosyltransferases (CGTases), offers a greener and more selective approach, utilizing starch as a substrate. On the other hand, chemical methods involve the conversion of starch using various chemical reagents under specific reaction conditions. Chemical methods, such as the Ritter reaction or the cyclization of starch using cyclodextrin glycosyltransferase, are also employed for large-scale production. Cyclodextrins have revolutionized the field of pharmaceuticals, offering solutions to various formulation challenges. One of the primary applications is the enhancement of drug solubility and bioavailability. By encapsulating poorly soluble drugs within their hydrophobic cavities, cyclodextrins form inclusion complexes, thereby improving their aqueous solubility and dissolution rates. This approach has been instrumental in the formulation of numerous drugs, including antifungals, anti-inflammatory agents, and anticancer drugs. Furthermore, cyclodextrins find application in drug delivery systems, where they serve as carriers for targeted and controlled release of drugs. By modifying the surface of cyclodextrins with targeting ligands or stimuli-responsive moieties, researchers have developed sophisticated drug delivery systems capable of site-specific delivery and triggered release of therapeutic agents. In the food and beverage industry, cyclodextrins are utilized for various purposes, including flavour masking, aroma encapsulation, and stabilization of food additives. Cyclodextrin complexes are employed to encapsulate volatile compounds responsible for undesirable flavours or odours, thereby masking their taste or smell. Additionally, cyclodextrins are used to stabilize food additives, vitamins, and antioxidants, enhancing their solubility and stability in food formulations. Cyclodextrins find extensive applications in the cosmetics industry, where they are employed for encapsulation of fragrances, vitamins, and active ingredients in skincare products. By encapsulating volatile fragrances within cyclodextrin complexes, manufacturers can prolong the fragrance release, ensuring long-lasting effects. Moreover, cyclodextrins enhance the stability and bioavailability of vitamins and active ingredients in cosmetic formulations, improving their efficacy.
