GRAPHICAL ABSTRACT
ABSTRACT
Jatrodagricaine A (1), a new labdane-type diterpenoid, together with three known derivatives (2−4) were isolated from the leaves of Jatropha podagrica. Their structures were elucidated by extensive spectroscopic methods. The absolute configuration of 1 was established by its biosynthetic pathway and comparison to known compound. All compounds were investigated for their anti-inflammatory and thioredoxin reductase (TrxR) inhibitory activities. Compound 1 showed potential inhibition in terms of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW264.7 macrophages with IC50 value of 40.6 ± 2.2 μM.
