| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

IeCPS2 is potentially involved in the biosynthesis of pharmacologically active Isodon diterpenoids rather than gibberellin.[Pubmed:22284743]
Phytochemistry. 2012 Apr;76:32-9.
The traditional Chinese medicinal plant, Isodon L., is remarkably rich in pharmacologically active ent-kaurane diterpenoids of diverse carbon skeletons. In an effort to create a resource for gene discovery and elucidate the biosynthesis of Isodonent-kaurane diterpenoids, three cDNAs (named IeCPS1, IeCPS2 and IeCPS2a) were isolated putatively encoding copalyl diphosphate synthases from Isodoneriocalyx leaves. Recombinant proteins of IeCPS1 and IeCPS2 were expressed, respectively, in Escherichia coli, and were shown to specifically convert geranylgeranyl diphosphate to copalyl diphosphate as demonstrated by GC-MS analyses. Based on tissue-specific expression and metabolic localization studies, the IeCPS2 transcripts were detected in young and mature leaves where the dominant ent-kaurane diterpenoid Maoecrystal B accumulates, whereas no detectable expression of IeCPS2 was observed in germinating seeds where the gibberellin biosynthetic pathway is usually active. In addition, no evidence for Maoecrystal B was found in germinating seeds. On the other hand, IeCPS1 transcripts significantly accumulated in germinating seeds as well as in leaves. The biochemical and molecular genetic evidence thus indicated that IeCPS2 is a copalyl diphosphate synthase potentially involved in the biosynthesis of Isodon diterpenoids in leaves, while IeCPS1 is more probably relevant to gibberellin formation and may, in addition, participate in Isodonent-kaurane diterpenoid production.
An attempt to enlarge the B ring of maoecrystal B, an ent-kaurane-type diterpene.[Pubmed:16931431]
J Asian Nat Prod Res. 2006 Sep;8(6):545-54.
An attempt to enlarge the B ring of Maoecrystal B (6), an ent-kaurane-type diterpene from Isodon eriocalyx (Labiatae), to obtain the desired compound 23 via six steps, led to the novel rearranged diterpene compound 22.
