Cell lines

PLC5, Hep3B, SK-Hep1, HuH7 and HepG2 cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.

Reaction Conditions

20 μM, 48 hours

Applications

Cell viability was determined by MTT assay after treatment for 48 h. Nintedanib significantly induced the accumulation of sub-G1-positive cells in all the tested HCC cells. Further, induction of apoptosis by nintedanib was also demonstrated by DNA fragmentation assay. Nintedanib exhibited a significant ratio of induction of DNA fragmentation at clinically relevant concentrations in a dose-dependent manner for all of the five HCC cell lines.

Animal models

Female NOD/SCID mice injected with A459, Calu-6 or H1993 cells

Dosage form

Oral administration, 50 mg/kg 5 days a week

Applications

In A549 xenografts, the single-agent therapy of BIBF 1120 effectively reduced primary tumor size in each setting. For all the three xenografts, a decrease in tumor growth rate was observed across all models, particularly in the combination groups, where the growth curve gradually became linear. End tumor volumes and weights were lower in BIBF 1120 and the combination groups compared to controls, across all models. In A549 and H1993 xenografts, combination was more effective than single agent therapy; however, in Calu-6 xenografts combination therapy was not different from BIBF 1120 single agent therapy.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Nintedanib (BIBF 1120) is an indolinone-derived oral active, triple angiokinase inhibitor of vascular endothelial growth factor receptor (VEGFR)1-3, fibroblast growth factor receptor (FGFR)1-3 and platelet-derived growth factor receptor (PDGFR)α/β1. It has shown potent antiangiogenic activity at nanomolar (IC50, 20-100 nmol/L) by blocking these receptor-mediated signaling pathways1,2. Nintedanib (BIBF 1120) is in clinical development for the treatment of idiopathic pulmonary fibrosis as these receptors have been shown to be potentially involved in the pathogenesis of pulmonary fibrosis3,4. As a novel angiogenesis inhibitor, it is also being widely evaluated in different cancer models and has displayed significant anti-tumor activities by inhibiting tumor blood vessel formation5-7.

To further evaluate its antitumor effects on multiple tumors, Nintedanib is currently entering several clinical trials, including non-small cell lung cancer8, ovarian cancer6, colorectal cancer7, hepatocellular carcinoma9 and many other solid tumors. In addition, the possibilities of combining Nintedanib therapy with other treatments such as docetaxel10 and afatinib 11are being tested in different tumor models. The most common drug-related adverse events in patients were diarrhea, nausea, vomiting and lethargy7.
