Myrsinane-Type Diterpenes: A Comprehensive Review on Structural Diversity, Chemistry and Biological Activities

Area of Science:

• Natural Product Chemistry
• Medicinal Chemistry
• Phytochemistry

Background:

• Euphorbia species are rich sources of polycyclic and macrocyclic diterpenes.
• Myrsinane-type diterpenes, derived from lathyrane structures, exhibit significant biological properties.
• These compounds are crucial in natural-product-based drug discovery.

Purpose of the Study:

• To review the distribution and diversity of 220 myrsinane-type diterpenes.
• To summarize isolation, structural elucidation, and biosynthetic pathways.
• To highlight key biological activities of these diterpenes.

Main Methods:

• Literature review of compounds isolated over four decades.
• Analysis of structural characteristics and diversity.
• Compilation of reported biological activities.

Main Results:

• Detailed description of 220 myrsinane-type diterpenes from approximately 20 Euphorbia species.
• Inclusion of myrsinane diterpenes from Jatropha curcas.
• Summary of plausible biosynthetic pathways and structural elucidation methods.

Conclusions:

• Myrsinane-type diterpenes possess a wide range of biological activities, including cytotoxic, immunomodulatory, and enzyme inhibitory effects.
• These compounds show potential for drug development, particularly in anticancer and antiviral research.
• Further research into their biosynthesis and pharmacological applications is warranted.
