Nine sesquiterpenes and eight flavonoids were isolated from Zingiber spectabile for the first time. Structures were determined by spectroscopic methods. The major compound zerumbone (1) was found to be the most active (IC50 13 μg mL−1) in cell growth inhibitory assay against colon carcinoma SW480 cells. 

Evaluation of phytochemical and pharmacological properties of Mikania cordata (Asteraceae) leaves

Anti-Proliferative Activity of Zerumbone Against Tumour Cell Lines

Evaluated in vitro the anti-proliferative activity of this bioactive compound, zerumbone, on seven cancer cell lines, it was found to be less toxic to the normal cell lines CHO, indicating the possible potential use of ZER for treatment of hematological cancers in addition to the cervical cancer.

Kalparinol, a Salvialane (Isodaucane) Sesquiterpenoid Derived from Native Australian Dysphania Species That Suggests a Putative Biogenetic Link to Zerumbone.

The coisolation of the humulene and isodaucane skeletons, combined with the lack of any cadalane systems, could suggest an alternate novel biogenetic pathway originating from zerumbone, which is unlike any other proposals for the isoducene system.

Biomedical Properties of a Natural Dietary Plant Metabolite, Zerumbone, in Cancer Therapy and Chemoprevention Trials

Much of the research outlined in this paper will serve as a foundation to explain ZER anticancer bioactivity, which will open the door for the development of strategies in the treatment of malignancies using ZER.
