Diterpenes are a class of organic compounds derived from isoprene units. Specifically, they are formed by the joining of four isoprene units. This molecular structure results in a carbon skeleton of 20 carbon atoms. Diterpenes are a diverse group of natural products found in many plants, fungi, and some marine organisms. Their biosynthesis typically follows the mevalonate or MEP pathway, leading to the formation of geranylgeranyl pyrophosphate (GGPP), which is the key precursor.

The structural variety among diterpenes is extensive, leading to a wide range of chemical properties and biological activities. They can exist as hydrocarbons, alcohols, aldehydes, acids, or be further functionalized with oxygen-containing groups such as epoxides, ketones, and esters. Common structural classes include linear diterpenes, monocyclic, bicyclic, tricyclic, and tetracyclic diterpenes, with notable examples including phytol, retinol, gibberellins, taxanes, and steroids.

Diterpenes play crucial roles in various biological processes. In plants, they are involved in growth regulation (e.g., gibberellins), defense mechanisms, and structural components. For example, resinous diterpenes protect trees from insect infestation and disease. In animals, some diterpenes have significant pharmacological properties. For instance, taxol (paclitaxel), a diterpene derived from the Pacific yew tree, is a widely used chemotherapy drug. Other diterpenes exhibit anti-inflammatory, antiviral, or antimicrobial activities, making them subjects of ongoing research in medicinal chemistry and pharmacology.
