Five new cassane diterpenes from the seeds and bark of Erythrophleum suaveolens
Résumé
Five new cassane-type diterpenoid heterosides, i. e. two cassane-type amides (1–2), two erythrophlamine-type amine esters (3–4) and a non‑nitrogenous erythrophlamine analogue (5) were isolated from the root barks (1–2) and the seeds (3–5) of Erythrophleum suaveolens. Their structures were unambiguously established by interpretation of their HRESIMS, 1D and 2D NMR data, and chemical degradation for sugar determination. Compounds 3–5 were evaluated for their cytotoxicity against a panel of three cell lines, revealing modest to strong activities.
