Phytochemical Name : Pristimerin

Properties Information
PhytoCAT-ID PhytoCAT-367
Phytochemical name or plant extracts Pristimerin
PMID 16093444
Literature evidence Treatment of tumor cells with pristimerin resulted in a rapid release of cytochrome c from mitochondria, which preceded caspase activation and the decrease of mitochondrial membrane potential.
IUPAC name methyl (2R,4aS,6aR,6aS,14aS,14bR)-10-hydroxy-2,4a,6a,6a,9,14a-hexamethyl-11-oxo-1,3,4,5,6,13,14,14b-octahydropicene-2-carboxylate
Phytochemicals’ class or type of plant extracts Triterpenoid

Other cancers Breast cancer, Pancreatic cancer, Leukemia
Target gene or protein FASN
Gene or Protein evidence (FASN) expression and FASN activity were downregulated by pristimerin.
Target pathways Pristimerin overcomes adriamycin resistance in breast cancer cells through suppressing Akt signaling, Pristimerin induces apoptosis and autophagy via activation of ROS/ASK1/JNK pathway in human breast cancer in vitro and in vivo.
IC50 pristimerin inhibited the cell viability of A549, MCF-7, MDA-MB-231, HepG2, and Hep3B cells, with IC50 values ranging from 0.42 to 0.61 μmol/L after a 72-hour treatment.
Potency pristimerin showed the most potent activity against nine tumor cancer cell lines, including vincristine-resistant oropharyngeal cancer KB cells and taxol-resistant ovarian cancer PTX10 cells, a potent and broad-spectrum antitumor agent, with activity against a wide range of different human cancers.
Cell line/ mice model MDA-MB-231
Additional information  Pristimerin did not significantly alter the protein level of Bcl-2 family members (Bcl-2, Bcl-X(L), and Bax), nor did it induce Bax translocation. Moreover, Bcl-2 overexpression fails to prevent pristimerin-induced apoptosis.
