Pushing the limits of concertedness. A waltz of wandering carbocations. [PDF]

open access: yes, 2019
Among the array of complex terpene-forming carbocation cyclization/rearrangement reactions, the so-called "triple shift" reactions are among the most unexpected.

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking

open access: yesJournal of Phycology, EarlyView.
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.

Two new cneorubin related diterpenes from the leaves of Guarea guidonia (Meliaceae)

open access: yesJournal of the Brazilian Chemical Society, 2000
Two new and two known cneorubin related diterpenes were isolated from the leaves of Guarea guidonia (Meliaceae). One of the new diterpenes has the unusual trans bicyclo[5.1.0]octane ring system. The structures were elucidated by spectral data.

Does coffee consumption alter plasma lipoprotein(A) concentrations? A systematic review [PDF]

open access: yes, 2017
Coffee consumption alters plasma lipid and cholesterol concentrations, however, its effects on lipoprotein(a) (Lp(a)) have received little study. The aim of this PRISMA compliant systematic review was to examine the role of coffee on serum Lp(a).

The Jasmonate‐Responsive SmMPK3–SmWRKY33 Module Positively Regulates Tanshinone Biosynthesis in Salvia miltiorrhiza

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Tanshinones, the major bioactive diterpenes in Salvia miltiorrhiza Bunge, are widely used to treat cardiovascular and cerebrovascular diseases. While jasmonates (JAs) are known to modulate tanshinones accumulation, the molecular link between JA signalling and tanshinone biosynthesis remains unclear.

Synthetic Biology and Metabolic Engineering of Microalgae for Sustainable Lipid and Terpenoid Production: An Updated Perspective

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Microalgae are increasingly recognised as powerful platforms for the sustainable production of lipids and terpenoids, with expanding applications in the food, fuel and biomanufacturing industries. In this updated review, we consolidate and critically assess the most recent advances in synthetic biology and metabolic engineering of key ...

Chemistry and Biological Activities of Terpenoids from Copaiba (Copaifera spp.) Oleoresins

open access: yesMolecules, 2012
Copaiba oleoresins are exuded from the trunks of trees of the Copaifera species (Leguminosae-Caesalpinoideae). This oleoresin is a solution of diterpenoids, especially, mono- and di-acids, solubilized by sesquiterpene hydrocarbons. The sesquiterpenes and

Heterologous Production of Forskolin in Tobacco (Nicotiana tabacum) via Glandular Trichome Specific Engineering and Metabolic Flux Redirection

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Plants are promising bioreactor for the sustainable and scalable production of high‐value natural bioactive compounds, because they can synthesise phytochemicals from CO2, light, water and minerals through their innate photosynthetic carbon assimilation machinery.
