Sesterterpenes

Sesterterpenes are a class of organic compounds belonging to the terpene family. They are characterized by their unique structure, which consists of 25 carbon atoms, making them larger than monoterpenes, sesquiterpenes, and diterpenes, but smaller than sesterterpenoids or terpenoids. Sesterterpenes are formed biosynthetically from five isoprene units. Their complex structures often feature cyclic arrangements and a variety of functional groups, contributing to their diverse chemical properties.

These compounds are found naturally in various organisms, particularly in fungi, marine invertebrates, and some plants. In fungi, sesterterpenes are known for their antimicrobial and antifungal activities. In marine environments, they have been identified in sponges and other sessile organisms, where they may play roles in defense mechanisms or interspecies communication. The study of sesterterpenes has revealed a wide range of biological activities, including cytotoxic, antiviral, and anti-inflammatory properties, making them of interest in natural product chemistry and drug discovery research. Due to their complex structures, the synthesis of sesterterpenes can be challenging, but ongoing research aims to develop efficient synthetic routes for their production and to explore their potential applications.
