diterpenoids การใช้

• The most hazardous are called methyl succidimido anthramoyl lycoctomine ( MSAL ) diterpenoids.
• Recently, the same group identified five new diterpenoids from " Sagittaria pygmaea ".
• It is able to thrive in such environments by using tricyclic diterpenoids as a carbon source.
• It is rather a rare form of diterpenoid and is structurally related to the bicyclic diterpenoids ginkgolide.
• The plant is well-protected by chemical defenses; these include diterpenoids, triterpenoids and flavonoids.
• "C schiedeanus " is known to contain the flavonol ayanin and cis-clerodane diterpenoids.
• Functionalized structures should instead be called diterpenoids, although in scientific literature the two terms are often used interchangeably.
• Diterpenoids, 4 isoprene units, are widely distributed in latex and resins, and can be quite toxic.
• Although a wide range of terpene structures exist few of them are biologically significant, by contrast diterpenoids possess a rich pharmacology and include important compounds such as retinol and phytol.
• Another group of epichlo?alkaloids are the indole-diterpenoids, such as lolitrem B, which are produced from the activity of several enzymes, including prenyltransferases and various monooxygenases.
• Seven new ent-rosane diterpenoids and a new labdane diterpene were recently ( 2006 ) purified from the Chinese medicinal plant, " Sagittaria sagittifolia " ( Alismaceae ).
• Like the " Neotyphodium " species, many species in " Epichlo?" produce biologically active alkaloids, such as ergot alkaloids, indole-diterpenoids ( e . g ., lolitrem B ), loline alkaloids, and the unusual guanidinium alkaloid, peramine.
• IPP and DMAPP are the end-products in either pathway, and are the precursors of isoprene, monoterpenoids ( 10-carbon ), diterpenoids ( 20-carbon ), carotenoids ( 40-carbon ), chlorophylls, and plastoquinone-9 ( 45-carbon ).
• The compound can be identified by GC-MS . A peak of m / z 123 is indicative of tricyclic diterpenoids in general, and phyllocladane in particular is further characterized by strong peaks at m / z 231 and m / z 189 . Presence of phyllocladane and its relative abundance to other tricyclic diterpanes can be used to differentiate between various oil fields.
