The Introduction of Terpenoids:


The terpenoids (aka isoprenoids) are a large (estimated 60% of known natural products ) and diverse group of lipids derived from five-carbon isoprene units assembled in thousands of combinations. Terpenoids are the largest group of phytochemicals consisting of several diverse compounds that are highly diverse in chemical structure and are a rich reservoir of candidate compounds for drug discovery. Most terpenoids are multicyclic structures that differ from one another not only in functional groups but also in their basic carbon skeletons.

Terpenoids are ubiquitous, thus, they are found in almost all classes of living organisms. They contribute to the flavor, scents, and color of plants' leaves, flowers, and fruits.

While we can identify isoprene units within a terpenoid structure and use that in its classification, the building block for terpenoid synthesis in nature is isopentenyl diphosphate. There are two major routes to the synthesis of IPP: (1) the mevalonate pathway and (2) the 1-deoxyxylulose pathway. Terpenoids show a range of pharmacological activities, such as anti-viral, hypoglycemic, anti-bacterial, anti-malarial, anti-inflammatory, and anti-cancer activities. Terpenoids are also essential for plant growth and development. The terpenoids produced by plants not only protect them against insects and herbivores but also protect from fungal diseases and infestations, whereas, in animals, terpenoids serve as the precursors of steroids and sterols.

Classification of Terpenoids:


Over a dozen naturally originated terpenoid compounds, in particular those derived from traditional Chinese medicine, were classified into five categories according to the structures, namely monoterpenoids, sesquiterpenoids, diterpenoids, triterpenoids and others. These subclassifications can be further classified according to different skeletons.

--Monoterpenoids: Monoterpenes and monoterpenoids represent a set of chemicals widely diffused in plants whose basic structure consists of two linked isoprene units. The monoterpenoids are formed by the addition of an alcoholic group to the monoterpene structure. Monoterpenoids are distributed in higher plants, algae, fungi, and even some insects and mammals, but they are very rare in mosses, ferns, and lichens. Characteristic features of monoterpenoids are their volatility and intensely pungent odors, and they are the most common components in plants responsible for fragrance and flavor. Monoterpenoids now appear as the one group of arthropod natural products for which knowledge of their biochemical, physiological, and ecological roles is most complete. To date, the two most well-studied examples are the iridoid monoterpenoids associated with Chrysomelid beetles and monoterpenes associated with bark beetles. 

--Sesquiterpenoids: Sesquiterpenoids are a class of enormously diverse natural products derived from three isoprene units and exist in a wide variety of forms, including linear, monocyclic, bicyclic, and tricyclic frameworks. Sesquiterpenoids are arguably the richest natural products from plants and microorganisms. Today, thousands of sesquiterpenoids have been discovered, with more than 100 skeleton types. The chemical diversity of sesquiterpenoids starts with the diverse sesquiterpene hydrocarbon backbones, which are created by carbocation cascade reactions programmed in sesquiterpene synthases (STSs). Sesquiterpenoids, with abundant structural skeleton types and a wide range of bioactivities, are considered good candidates to be antibacterial and antifungal agents. In the past decades, many sesquiterpenoids have been isolated from plants and fungi that exhibit good antibacterial and antifungal activities.

--Diterpenoids: Diterpenoids are chemical compounds containing 20 carbon atoms and belong to the terpenoid class. They derive from geranylgeraniol, a C20 precursor, have a C20H32 basic structure, and are composed of four isoprene units. Diterpenoids can be classified as linear, bicyclic, tricyclic, tetracyclic, pentacyclic, or macrocyclic diterpenes depending on their skeletal core. Diterpenoids (diterpenes) occur in many plants used for their reputed medicinal properties and have been of interest as potential phytopharmaceuticals in the form of standardized plant extracts. Many plants produce diterpenoids as secondary metabolites, which serve various biological functions. These compounds often contribute to the plant's defense mechanisms against herbivores, pests, and pathogens. One of the most widely investigated phytopharmaceuticals is Ginkgo biloba, which has produced promising outcomes on memory and cognitive functions in numerous clinical studies.

--Triterpenoids: Triterpenoids are a large group of natural products derived from C30 precursors. The triterpenoids group displays well over 100 distinct skeletons. This class of natural products includes triterpenes, steroids, limonoids, quassinoids, and triterpenoidal and steroidal saponins. Triterpenoids, which extract from Sympcocos Racenosa, are a group of Terpenes (isoprenoids) are defined as terpenoid derviatives of triterpene molecules. The triterpenoids are formed biosynthetically from six isoprene units and share in common the C30 acyclic precursor squalene. Different types of ring closure in squalene can give rise to many different skeletal types of triterpenoids. Over 4000 natural triterpenoids have been isolated, and more than 40 skeletal types have been identified. Triterpenoids are cyclized from oxidized squalene precursors by oxidosqualene cyclases, creating more than 100 different cyclical triterpene scaffolds.
