In the course of our screening for a new anti-tumor substance, the bisabolane sesquiterpenoid endoperoxide, 3,6-epidioxy-1,10-bisaboladiene (EDBD), was isolated from the edible wild-plant, Cacalia delphiniifolia. EDBD showed cytotoxicity toward human chronic myelogenous leukemia K562 and human prostate carcinoma LNCaP cell lines with IC50 values of 9.1 μM and 23.4 μM, respectively. DNA fragmentation and condensation of chromatin, the hallmarks of apoptosis, appeared in K562 cells after an 18-h treatment with EDBD. α-Curcumene, a bisabolane sesquiterpene that lacks the endoperoxide moiety of EDBD, also showed cytotoxicity toward both K562 and LNCaP cell lines at over a 10-times higher dose than that of EDBD. The results indicate the importance of the endoperoxide structure within EDBD to its anti-tumor activity in vitro.
