Article Abstract
Corymbinols A () and B (/), unprecedented bis-β-triketone-sesquiterpene and -chalcone hybrids, together with their biogenic precursors corymbinol C () and rhodomyrtosone E () were isolated from the untapped fruit of . The absolute configurations of these compounds were determined by NMR spectroscopy, electronic circular dichroism (ECD) calculations, and X-ray crystallography. Compound exhibited moderate inhibitory activity against cuproptosis in HepG2 cells by 31% at a nontoxic concentration of 20 μM.
