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.

Jatropha Diterpenes: An Updated Review Concerning Their …
Oct 19, 2024 · Among its genera, Jatropha is a conspicuous producer of diterpenes and includes approximately 175 species, many of which have medicinal uses. To date, 140 diterpenes from Jatropha (JTDs) have been reported. Given their structural diversity and notable biological activities, this work aims to highlight the pharmaceutical potential of JTDs.
An Overview of Biotransformation and Toxicity of Diterpenes
This review presents an overview of biotransformation processes of diterpenes carried out by microorganisms, plant cell cultures, animal and human liver microsomes, and rats, chickens, and swine in vivo and highlights the main enzymatic reactions involved in these processes and the role of diterpenes that may be effectively exploited by other ...
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.
Diterpenes for Therapeutic Use - SpringerLink
Jan 1, 2013 · 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.
Diterpene - an overview | ScienceDirect Topics
Diterpenes are fungal and plant secondary metabolites formed from four isoprene units. Most diterpenes are nonvolatile but sometimes they are found in very small amounts in essential oils (Fig. 10).
Diterpene - an overview | ScienceDirect Topics
Diterpenes are a diverse group of structurally complex natural products with a wide spectrum of biological activities, including antidiabetic potential. In the last 25 years, numerous diterpenes have been investigated for antidiabetic activity, with …
The antioxidant activity of natural diterpenes: theoretical insights
Apr 4, 2020 · This study is thus aimed to (1) investigate the thermodynamics of the antioxidant activity of diterpenes through three mechanisms: formal hydrogen transfer (FHT), sequential electron transfer proton transfer (SETPT), or sequential proton loss electron transfer (SPLET); (2) kinetically evaluate the HOO˙ radical scavenging capacity of diterpenes ...
