Efficient production of clerodane and ent-kaurane diterpenes through truncated artificial pathways in Escherichia coli [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2022
The clerodane and ent-kaurane diterpenoids are two typical categories of diterpenoid natural products with complicated polycyclic carbon skeletons and significant pharmacological activities. Despite exciting advances in organic chemistry, access to these

Methoxylated Flavonols and ent-Kaurane Diterpenes from the South African Helichrysum rutilans and Their Cosmetic Potential [PDF]

open access: yesPlants, 2023
Chromatographic fractionation of a methanol extract of Helichrysum rutilans afforded seven known compounds. The isolated compounds were identified as 5,7,8-trihydroxy-3,6-dimethoxyflavone-8-O-2-methyl-2-butanoate (C-1), 5,7-dihydroxy-3,6,8 ...

Mechanistic Pathways and Molecular Targets of Plant-Derived Anticancer ent-Kaurane Diterpenes [PDF]

open access: yesBiomolecules, 2020
Since the first discovery in 1961, more than 1300 ent-kaurane diterpenoids have been isolated and identified from different plant sources, mainly the genus Isodon. Chemically, they consist of a perhydrophenanthrene subunit and a cyclopentane ring.

Structure-based drug design studies of the interactions of ent-kaurane diterpenes derived from Wedelia paludosa with the Plasmodium falciparum sarco/endoplasmic reticulum Ca2+-ATPase PfATP6 [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2015
Malaria is responsible for more deaths around the world than any other parasitic disease. Due to the emergence of strains that are resistant to the current chemotherapeutic antimalarial arsenal, the search for new antimalarial drugs remains urgent though

Three New Ent-Kaurane Diterpenes with Antibacterial Activity from Sigesbeckia orientalis [PDF]

open access: yesMolecules
Three novel ent-kaurane diterpenes, namely sigesbeckin A–C (1–3), in conjunction with eight previously identified analogues (4–11), were isolated from Sigesbeckia orientalis. Their chemical structures were resolved through multiple spectroscopic analyses.
