Calixarene: A Supramolecular Material for Treating Cancer

Abstract

Abstract: Cancer is a disease with a high mortality rate; therefore, research on new treatment strategies is essential. There has been increased interest in novel drug delivery systems (DDS) in recent years, such as calixarene, one of the most important principal molecules in supramolecular chemistry. Calixarene is a cyclic oligomer of phenolic units linked by methylene bridges that belongs to the third generation of supramolecular compounds. By modifying the phenolic hydroxyl end (lower edge) or the para-position, a wide range of calixarene derivatives can be obtained (upper edge). Drugs are combined with calixarenes to modify and have new properties, such as strong water solubility, the ability to bond with guest molecules, and excellent biocompatibility. In this review, we summarize the applications of calixarene in the construction of anticancer drug delivery systems and its application in clinical treatment and diagnosis. It provides theoretical support for the diagnosis and treatment of cancer in the future.
