Phytochemical Name : Cyclovirobuxine D (CVB-D)

Properties Information
PhytoCAT-ID PhytoCAT-266
Phytochemical name or plant extracts Cyclovirobuxine D (CVB-D)
PMID 24758922
Literature evidence In this study, we reported that cyclovirobuxine D (CVB-D), an alkaloid component in a traditional Chinese herb, could induce autophagy in the MCF-7 human breast cancer cell line.
IUPAC name (1S,3R,6S,8R,11S,12S,14R,15S,16R)-7,7,12,16-tetramethyl-6-(methylamino)-15-[(1S)-1-(methylamino)ethyl]pentacyclo[9.7.0.01,3.03,8.012,16]octadecan-14-ol
Phytochemicals’ class or type of plant extracts Alkaloid
Source of phytochemicals or plant Extracts Buxus microphylla
Geographical availability Japan
Plant parts Root
Other cancers Breast cancer
Target gene or protein LC3-I, LC3-II, ATG5
Gene or Protein evidence Western blot analysis revealed that CVB-D significantly promoted the conversion from LC3-I to LC3-II and the expression of autophagy-related protein 5 (ATG5), which are both essential for autophagosome formation.
Target pathways Akt/mTOR pathway
IC50 10 ± 2.51 μM against MCF-7
Potency These findings shed new light on the pharmacological actions and mechanism of CVB-D and may support the potential utility of autophagy inducers in cancer treatment.
Cell line/ mice model MCF-7
Additional information  After CVB-D treatment, a clear accumulation of autophagosomes was observed accompanied with elevated LC3 fluorescent puncta.
