Twenty new ingol diterpenoids, euphornans A-T (1-20), representing a rare class of C-19-oxidated and H-2, H-3 beta-oriented ingols, were isolated from the seeds of Euphorbia marginata. Their structures including absolute configurations were elucidated by extensive spectroscopic analysis, ECD analysis, and single crystal X-ray diffraction. Compounds 1-20 were screened for the multidrug resistance (MDR) reversal activity on P-glycoprotein (Pgp)-dependent MDR cancer cell line HepG2/ADR, and 11, 14, and 18 were identified as potent MDR modulators that could enhance the efficacy of anticancer drug adriamycin to ca. 20 folds at 5 mu M. The Pgp inhibition mechanism and brief structure-activity relationships (SARs) of these compounds were also discussed.
