Diterpene - Wikipedia
Diterpenes are a class of terpenes composed of four isoprene units, often with the molecular formula C 20 H 32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate.

Diterpenes for Therapeutic Use - SpringerLink
2013年1月1日 · In this chapter, we describe the main structural type of diterpenes isolated from plants, their biosynthesis, biological activity, and therapeutic uses. The most important diterpene skeletal types in terms of number and distribution are shown in Fig. 102.1, classified as bicyclic, tricyclic, tetracyclic and pentacyclic, and macrocyclic ring.
More is better: the diversity of terpene metabolism in plants
2020年6月1日 · In the last decade alone, several unexpected findings have been reported, including the discovery of new types of substrates, unusual enzymatic reactions, and extensive integration among subcellular compartments in the biosynthesis of terpenes. Here, we would like to highlight some of these new developments, with emphasis on the most recent ones.
Diterpene - an overview | ScienceDirect Topics
Diterpenes are a group of terpenoids commonly found in terrestrial and marine organisms, characterized by a C-20 backbone formed by different combinations of isoprene units. They exhibit a wide range of biological activities such as antifungal, cytotoxic, antioxidant, and potential chemopreventive effects.
Terpenes: Chemistry, Biological Role, and Therapeutic Applications
2013年1月1日 · Terpenoids are naturally occurring hydrocarbons produced by a wide variety of plants and animals. They are classified based on five-carbon (isoprene) units as their building blocks, numbering more than 55,000 molecules having been discovered till date.
Diterpene - an overview | ScienceDirect Topics
Fungal indole diterpenes (IDTs) are isolated as mycotoxins and antiinsectants. Their characteristic molecular structures have prompted research on the mechanisms of IDT biosynthesis. Recent technology in DNA sequencing and bioinformatics has enabled rapid access to the biosynthetic gene clusters of IDTs.
