摘要
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 describe the isolation and structure elucidation of the DDO (trigocherrins B-F and trigocherriolides A-D). We also report the antiviral activity of trigocherrins A, B and F (1, 2 and 6) and trigocherriolides A, B and C (7-9) against various emerging pathogens: chikungunya virus (CHIKV), Sindbis virus (SINV), Semliki forest virus (SFV) and dengue virus (DENV).
