Description

Telatinib (Bay 57-9352) is an orally active, small molecule inhibitor of VEGFR2, VEGFR3, PDGFα, and c-Kit with IC50s of 6, 4, 15 and 1 nM, respectively.

IC50 & Target[1]

VEGFR2

6 nM (IC50)

VEGFR3

4 nM (IC50)

PDGFRα

15 nM (IC50)

c-Kit

1 nM (IC50)

In Vitro

Telatinib has low affinity for the Raf kinase pathway, epidermal growth factor receptor family, the fibroblast growth factor receptor (FGFR) family, or the Tie-2 receptor[2]. Telatinib is metabolized by various cytochrome P450 (CYP) isoforms including CYP3A4/3A5, CYP2C8, CYP2C9, and CYP2C19 as well as by uridine diphosphate glucuronosyltransferase 1A4 (UGT1A4), with the formation of the N-glucuronides of telatinib as the major biotransformation pathway in man. In vitro studies show telatinib to be a weak substrate of the adenosine triphosphate binding cassette (ABC) B1 (ABCB1) transporter[3]. Telatinib at 1 μM significantly enhances the intracellular accumulation of [3H]-mitoxantrone (MX) in ABCG2-overexpressing cell lines. In addition, telatinib at 1 μM significantly reduces the rate of [3H]-MX efflux from ABCG2-overexpressing cells. Furthermore, telatinib significantly inhibits ABCG2-mediated transport of [3H]-E217βG in ABCG2 overexpressing membrane vesicles[4].

In Vivo

Telatinib causes a significant decrease in endothelium-dependent and endothelium-independent vasodilation. VEGF inhibition by itself decreases NO synthesis, which promotes vasoconstriction, increases peripheral resistance, and therefore can induce an increase in blood pressure[1]. Telatinib (15 mg/kg) with doxorubicin (1.8 mg/kg) significantly decreases the growth rate and tumor size of ABCG2 overexpressing tumors in a xenograft nude mouse model[4].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (5.08 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[4]

The vanadate (Vi)-sensitive ATPase activity of ABCG2 in the membrane of High Five insect cells is measured. Briefly, membrane (2 μg/0.06 mL) are incubated in ATPase assay buffer with or without 0.4 mM vanadate at 37°C for 5 min and then incubated with varying concentrations of telatinib at 37°C for 5 min. The ATPase reaction is started by the addition of 4 mM Mg-ATP. After incubating at 37°C for 10 min, the reactions are stopped by adding 0.05 mL of 10% SDS solution. The liberated inorganic phosphate is measured[4].

Animal Administration
[4]

Mice: The mice are randomized into four groups and treated with one of the following regimens: (a) vehicle (10% N-methyl-pyrrolidinone, 90% polyethylene glycol 300) (q3d×6), (b) DOX (1.8 mg/kg, i.p., q3d×6), (c) telatinib dissolved in 10% N-methyl-pyrrolidinone, 90% polyethylene glycol 300 (15 mg/kg, p.o., every 2nd and 3rd day; total 12 times), and (d) DOX (1.8 mg/kg, i.p., q3d×6) + telatinib (15 mg/kg, p.o., every 2nd and 3rd day, given 1 h before giving DOX; total 12 times). DOX for injection is prepared by dissolving in saline. Tumor volume is measured using calipers and body weights are recorded[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
