Certificate of Analysis

  • This product was previously Cat. No. I-9077, Intedanib, and Cat. No. V-9077, Vargatef.
  • This research compound is the free base form of nintedanib. We also offer the ethanesulfonate salt form; please see Nintedanib, Ethanesulfonate Salt, Cat. No. N-9055.
  • Nintedanib is an indolinone derivative that potently inhibits vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR) and fibroblast growth factor receptor (FGFR) kinase activity in enzymatic assays (table 1). It blocks mitogen-activated protein kinase and Akt signaling pathways in three cell types contributing to angiogenesis, namely endothelial cells, pericytes, and smooth muscle cells, and it inhibits cell proliferation with an EC50 of 10-80 nM. Hilberg, F., et al. "BIBF 1120: triple angiokinase inhibitor with sustained receptor blockade and good antitumor efficacy." Cancer Res. 68: 4774-4782 (2008).

  • Nintedanib significantly decreased blood vessel area and inhibited tumour growth. Zips, D., et al. "Triple angiokinase inhibition, tumour hypoxia and radiation response of FaDu human squamous cell carcinomas." Radiother. Oncol. 92: 405-410 (2009).
  • A reproducible hepatic perfusion index (HPI) was determined by using quantified gadopentetate dimeglumine (Gd-DTPA) concentration. The HPI decreased significantly at 28 days after treatment with nintedanib. HPI may be useful for monitoring antiangiogenic treatment response of hepatic metastases. Miyazaki, K., et al. "Quantitative mapping of hepatic perfusion index using MR imaging: a potential reproducible tool for assessing tumour response to treatment with the antiangiogenic compound BIBF 1120, a potent triple angiokinase inhibitor." Eur. Radiol. 18: 1414-1421 (2008).
