Abstract:
A new triterpenoid saponin, julibroside J(28) (1), was isolated from the stem bark of Albizia julibrissin Durazz (Leguminosae) by using chromatographic method. The structure of 1 was established by spectroscopic methods. 1 displayed significant antitumor activity in vitro against PC-3M-1E8, Bel-7402, and HeLa cancer cell lines at 10 microM assayed by SRB method.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
