Phytochemical Name : Vinorelbine

Properties Information
PhytoCAT-ID PhytoCAT-1764
Phytochemical name or plant extracts Vinorelbine
PMID 22122393
Literature evidence The antitumor activity of VNR is thought to be due primarily to inhibition of mitosis at metaphase through its interaction with tubulin.

Target gene or protein Caspase 3, Caspase 9, Caspase 8, cyt-c, Bid, HER2, Tp53, Bax, Bcl-2 mRNA , miR-222-3p
Gene or Protein evidence Western blotting suggests that vinorelbine cleaves caspase-3, -9 and -8 and reduces the amount of mitochondrial cytochrome c. A downstream substrate for caspase-8, Bid, is also cleaved in vinorelbine-treated cells, but the Bid truncation is also observed in caspase-8-deficient Jurkat cells. A synergistic effect has been observed between vinorelbine and trastuzumab in patients with a hyperexpression of HER2 in their tumours. Treatment of BT-20 cells with vincristine, vinblastine, and/or vinorelbine resulted in upregulation of TP53 expression. On the other hand, treatment of SK-BR-3 cells with any of these vinca alkaloids led to an increase in the BAX/BCL2 mRNA ratio, implying the activation of the intrinsic apoptotic pathway. No concomitant alteration in TP53 expression was observed in treated SKBR- 3 cells. Regarding the miRNAs examined in this study, miR-222-3p expression exhibited the most remarkable modulations in both treated cell lines.
Target pathways In this report, we demonstrate that VNB, as an antimicrotubule agent, induces apoptosis in breast cancer cell line, MX-1 via a mitochondrial pathway.
IC50 NA
Potency Vinorelbine is active in metastatic breast cancer with a first time response rate of 40% to 52%. High response rates were observed with combination chemotherapies of vinorelbine and other active agents for breast cancer.
Cell line/ mice model MX-1, MCF-7
Additional information  Vinorelbine is a chemotherapeutic vinca alkaloid clinically prescribed for non-small cell lung cancer and breast cancer.
