Exploring the Antiproliferative Activity of Flavolignans From the Leaves of Casearia arborea (Salicaceae)

open access: yesChemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT The Casearia genus (Salicaceae) is well known as a source of natural antitumor prototypes, as described for clerodane diterpenes. In this way, the dichloromethane phase from leaves of Casearia arborea was phytochemically evaluated in liquid chromatography coupled to high‐resolution mass spectrometry, furnishing flavonoid, flavolignan, and ...

CYP76BK1 orthologs catalyze furan and lactone ring formation in clerodane diterpenoids across the mint family

open access: yesThe Plant Journal, Volume 120, Issue 3, Page 984-997, November 2024.
SUMMARY The Lamiaceae (mint family) is the largest known source of furanoclerodanes, a subset of clerodane diterpenoids with broad bioactivities including insect antifeedant properties. The Ajugoideae subfamily, in particular, accumulates significant numbers of structurally related furanoclerodanes.

Cytotoxic Clerodane Diterpenes from Zuelania guidonia

open access: yes, 2016
The leaves of Zuelania guidonia yielded eight new clerodane diterpenes, namely, zuelaguidins A–H (1–8), and the known clerodane diterpene esculentin A (9). Some of these structures contained a 3,6-dihydro-1,2-dioxin moiety.

Identification of clerodane diterpene modifying cytochrome P450 (CYP728D26) in Salvia divinorum ‐ en route to psychotropic salvinorin A biosynthesis

open access: yesPhysiologia Plantarum, Volume 176, Issue 5, September/October 2024.
Abstract Salvia divinorum is a hallucinogenic plant native to the Oaxaca in Mexico. The active ingredient for psychotropic effects in this plant is salvinorin A, a potent and highly selective κ‐opioid receptor agonist. Salvinorin A is distinct from other well‐known opioids, such as morphine and codeine, in that it is a non‐nitrogenous diterpenoid with ...
