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 ...

Diterpene Synthase‐Catalyzed Biosynthesis of Distinct Clerodane Stereoisomers

open access: yesChemBioChem, 2018
AbstractThe diterpene synthase clerodienyl diphosphate synthase 1 (PvCPS1) from the crop plant switchgrass (Panicum virgatum) stereoselectively converts (E,E,E)‐geranylgeranyl diphosphate (GGPP) into the clerodane natural product, cis‐trans‐clerodienyl diphosphate (CLPP, 1).

Ameliorating effects of Clerodendrum viscosum leaves on lead‐induced hepatotoxicity

open access: yesFood Science &Nutrition, Volume 12, Issue 9, Page 6472-6481, September 2024.
Lead (Pb), a common toxicant is ubiquitously present in environment. Chronic Pb exposure affects almost every organ system of human body including liver. Supplementation of Clerodendrum viscosum leaves provided significant protection against the changes in the activities of liver function biomarkers and antioxidant enzymes, levels of Nrf2 and IL‐6, and
