Four new labdane-derived diterpenes, iso-dulcinol (1), 4-epi-scopadulcic acid B (2), dulcidiol (4), and scopanolal (5), together with two known diterpenes, dulcinol/scopadulciol (3) and scopadiol (6), were isolated from the aerial parts of Scoparia dulcis. The structures were determined by extensive

Ingia / Ingia

Scoparia dulcis biosynthesize bioactive diterpenes, such as scopadulcic acid B (SDB), which are known for their unique molecular skeleton. Although the biosynthesis of bioactive diterpenes is catalyzed by a sequence of class II and class I diterpene synthases (diTPSs), the mechanisms underlying this

Specific inhibitors of the MVA pathway (pravastatin) and the MEP pathway (fosmidomycin) were used to interfere with the biosynthetic flux which leads to the production of aphidicolin-like diterpene in leaf organ cultures of Scoparia dulcis. Treatment of leaf organs with fosmidomycin resulted in dose
