Abstract
Phytochemical investigation of roots of Euphorbia ebracteolata Hayata led to ten higher diterpenoids including seven undescribed ones (1-7) and three analogues (8-10), accompanied by four derivatives (7a and 9a-9c) obtained via chemical correlation. Notably, compound 1 represents a rare dinor-ent-isopimarane diterpenoid. Their structures were fully characterized using a combination of spectroscopic, ECD, chemical, and single-crystal X-ray diffraction means. Cytotoxicity screening suggested that the oxidized derivative of 7 (7a) displayed the most potent activity against non-small-cell lung cancer (NSCLC) cell line HCC827, comparable to the positive control, cisplatin. Mechanistic study revealed that 7a could arrest cell cycle at G1/S phase and induce apoptosis.
