A novel ent-kaurane diterpenoid dimer, fritillebinide B (1) together with one known diterpenoid dimer fritillebinide A (2) were isolated from the bulbs of Fritillaria eheiensis var. purpurea G.D. Yu et P. Li. Compound 1 has been established to be ent-3beta-acetoxy-kauran-16beta,17-acetal ent-16beta-kauran-17(R)-aldehyde (1) by means of spectral analysis and chemical evidence.

    We found the compound reduced mouse sarcoma 180 tumor volume by inducing apoptosis of tumor and tumor-associated endothelial cells. An examination of the effects of philinopside A on the angiogenesis-related receptor tyrosine kinases (RTKs) showed that philinopside A broadly inhibited all tested RTK...
