  • Title: Daphnane- and tigliane-type diterpenoid esters and orthoesters from Pimelea elongata.
    Author: Hayes PY, Chow S, Somerville MJ, Fletcher MT, De Voss JJ.
    Journal: J Nat Prod; 2010 Nov 29; 73(11):1907-13. PubMed ID: 21049973.
    Abstract:
    Investigation of Pimelea elongata ("Lakebed Pimelea") afforded 18 tigliane- and daphnane-type diterpenes (1-18). Eight of these were new compounds: four (1-3, 5) tigliane esters and four (7, 8, 10, 11) daphnane orthoesters. The 10 known compounds were 12-O-decanoylphorbol-13-acetate (4), P. simplex subtoxin B (6), wikstroelide E (9), pimelotides A and B (12, 13), gnidiglaucin (14), simplexin (15), huratoxin (16), kirkinine D (17), and 12-β-acetoxyhuratoxin (18). The structures and relative configurations of the new compounds were determined by 1D and 2D NMR spectroscopic studies in combination with MS analyses.
