The chemical study of the bark and the wood of Trigonostemon cherrieri, a rare endemic plant of New Caledonia, led to the isolation of a series of highly oxygenated daphnane diterpenoid orthoesters (DDO) bearing an uncommon chlorinated moiety: trigocherrins A-F and trigocherriolides A-D. Herein, we
Four highly oxygenated daphnane diterpenoids, trigonothyrins D-G (1-4), were isolated from the stems of Trigonostemon thyrsoideum, and their structures were elucidated on the basis of extensive spectroscopic studies. Inhibitory activity against HIV-1 was assessed for compounds 1, 3 and 4, wherein, 3
A chemical study of the Vietnamese plant species Trigonostemon howii led to the isolation of a new tigliane-type diterpenoid, trigowiin A (1), along with several known coumarins and phenylpropanoids. The planar structure and the relative configuration of compound 1 were elucidated based on
