Background Information

Cabozantinib (also called XL184, BMS-907351 Cometriq [1]), is an inhibitor of multiple receptor tyrosine kinases (RTKs), including vascular endothelial growth factor receptor 2 (VEGFR2), hepatocyte growth factor receptor (MET), and rearranged during transfection (RET) [2] [3], with IC50 values of 0.035 nmol/L, 1.3 nmol/L and 5.2 nmol/L to VEGFR2, MET and RET, respectively [4].

RTKs transmit a wide array of extracellular signals for regulating differentiation and proliferation to cells. Ligand binding triggers many events such as autophosphorylation of tyrosine residues and receptor dimerization [5].

TT cell line was a human MTC cell line that had an activating C634W RET mutant and was expressing calcitonin. In this cell line, cabozantinib inhibited the autophosphorylation of RET with an IC50 value of 85 nmol/L. In TT cells grown for 72 h in 10% serum, cabozantinib dose-dependently inhibited cell proliferation with an IC50 value of 94 nmol/L [4].

Administrated with cabozantinib daily orally at doses of 10, 30, or 60 mg/kg, nu/nu mice bearing TT xenograft tumors, showed a significantly inhibited tumor growth compared with vehicle-treated group. At both doses of 30 and 60 mg/kg, cabozantinib caused markedly and significantly reduced circulating calcitonin (75%; p< 0.005) in serum compared with vehicle-treated control animals [4].

Cabozantinib (XL 184) is an orally bioavailable, small molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Cabozantinib strongly binds to and inhibits several tyrosine receptor kinases. Specifically, cabozantinib appears to have a strong affinity for the hepatocyte growth factor receptor (Met) and vascular endothelial growth factor receptor 2 (VEGFR2), which may result in inhibition of tumor growth and angiogenesis, and tumor regression. This agent has also been shown to inhibit mast/stem cell growth factor (KIT), FMS-like tyrosine kinase 3 (Flt3) and tyrosine-protein kinase receptor (Tie-2). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus).

Protocol(Only for Reference)

Cell Experiment

Cell lines Human microvascular endothelial (HMVEC) cells
Conditions IC50: 6.7 nM, 7 days
Method HMVEC cells were incubated with VEGF in the presence of cabozantinib and tubule formation visualized by immunostaining for CD31. Cabozantinib inhibited tubule formation with an IC50 value of 6.7 nM with no evidence of cytotoxicity, showing that cabozantinib exerts an antiangiogenic rather than cytotoxic effect.
Source Apexbio Technology LLC
Cell lines ST88-14, STS26T, and MPNST724
Conditions Dissolved in DMSO, final concentrations ~10 μM; 48 hours
Method Cells are exposed to various concentrations of XL184 for 48 hours. Cell growth is determined by MTS assays using CellTiter96 Aqueous Non-Radioactive Cell Proliferation Assay kit. Absorbance is measured at a wavelength of 490 nm, and the absorbance values of treated cells are presented as a percentage of the absorbance of untreated cells.

Applications A single 100 mg/kg oral dose of cabozantinib resulted in inhibition of phosphorylation of MET 2 to 8 hours postdose in H441 tumors that harbor constitutively phosphorylated MET. This effect was reversible, as MET phosphorylation returned to basal levels by 48 hours after treatment.
