Terpenoid compounds Catalog

Terpenoids, sometimes called isoprene, is a large and diverse natural organic chemicals, similar to the terpenoids, is composed of five carbon isoprene, assembly and improvement in thousands of ways. Most of them are polycyclic, and they're different not only in the functional groups, but also in their basic carbon skeletons. These lipids, which can be found in a variety of organisms, are the largest group of natural products. About 60% of the known natural products are terpenoids

Plant terpenes are widely used for their aromatic properties and play a role in traditional Chinese medicine. Terpenoids contribute to the smell of eucalyptus, cinnamon, cloves and ginger, sunflower yellow and tomato red. famous terpenoids including citral, menthol, camphor, salvinorin A in plant Salvia divinorum, cannabinoid found in ginkgo, ginkgo lactone and bilobalide, and finds the curcumin turmeric and mustard seeds.

Triterpenoid saponins have significant structural and bioactive diversity. They are increasingly important in cancer treatment because of their efficacy and safety. In this chapter, the origin, pharmacological action, structure-activity relationship and clinical research of triterpenoid saponins against cancer have been updated, especially the molecular mechanism of its therapeutic properties. Relevant literature and research reports were collected through PubMed. Anti-cancer triterpenoid saponins by regulation and cell proliferation, apoptosis, autophagy, transfers, angiogenesis, inflammation, oxidative stress, multi-drug resistance, cancer stem cells and the multiple signals associated microRNAs targets to inhibit the formation and development of cancer. The molecular basis of triterpenoid saponins in tumor chemotherapy and chemotherapy was reviewed.

Steroids and sterols in animals are produced by terpenoids precursors. Terpenoids are sometimes added to proteins, for example, to enhance their binding to cell membranes. This is isopentyl.

Terpenes are hydrocarbons formed by condensation of several 5-carbon isoprene units. Isoprene units have the formula CH2=C(CH3)CH=CH2. Terpenoids can be considered modified terpenes in which methyl groups are removed or removed, or oxygen atoms are added. (some authors use the term terpene more widely, including terpenoids.) Like terpenes, terpenoids can be classified according to the number of isoprene units in use:

• Half terpene, 1 isoprene unit (5 carbons)
• Monoterpenes, 2 isoprene units (10C)
• Sesquiterpenoids, 3 isoprene units (15C)
• Diterpenes, 4 isoprene units (20C)(e.g. ginkgolide)
• Triterpenes, 5 isoprene units (25C)
• Triterpenes, 6 isoprene units (30C)(such as sterol)
• Tetrene, 8 isoprene units (40C)(e.g. carotenoids)

Terpenoids can also be classified according to the number of cyclic structures they contain. Salkowski tests can be used to identify terpenoids. Meroterpenes are any compound, including many natural products, with partial terpenes structure.
