Properties Information
PhytoCAT-ID PhytoCAT-147
Phytochemical name or plant extracts Helenalin
PMID 25435410
Literature evidence A recent study used the PLGA-PEG-helenalin complex, and free helenalin, to inhibit the expression of telomerase in the breast cancer cell line.
IUPAC name (3aR,5R,5aR,8aR,9S,9aS)-9-hydroxy-5,8a-dimethyl-1-methylidene-3a,4,5,5a,9,9a-hexahydroazuleno[6,7-b]furan-2,8-dione

Geographical availability Arizona, California, Mexico Northwest, Nevada, Utah
Plant parts NA
Other cancers Breast cancer
Target gene or protein Telomerase
Gene or Protein evidence This finding has been proved through the decrease of telomerase gene expression by real-time PCR.
Target pathways NA
IC50 1.3 μM against T47D for 72h
Potency In this study, we demonstrated that the NC-helenalin complex is more effective than free helenalin in inhibiting the growth of breast cancer cells.
Cell line/ mice model T47D
Additional information  The nuclear factor-kappaB (NF-kappaB)-DNA binding inhibitor helenalin (20 microM) also prevented induction.
