产品名称
ARQ 197
产品介绍
Tivantinib 是一种高选择性c-Met酪氨酸激酶抑制剂,Ki为 355 nM。
生物活性

Tivantinib is a highly selectivec-Mettyrosine kinase inhibitor with aKiof 355 nM.

IC50& Target

Ki: 355 nM (c-Met)[1]

体外研究
(In Vitro)

Tivantinib (ARQ 197) selectively inhibits c-Met activity in cell-free and cell-based assays. c-Met-expressing cancer cell lines treated with Tivantinib display either a dose-dependent loss of proliferative capacity or caspase-dependent apoptosis that positively correlates with either ligand-dependent c-Met activity or constitutively active c-Met. To examine the biochemical mode of inhibition of Tivantinib, kinetic analyses are done using recombinant human c-Met in a filtermat-based assay. The Kmof ATP is 50.5±2.2 μM, which is similar to the Kmvalue of ATP. In these kinetic studies, Tivantinib inhibits human recombinant c-Met with a calculated inhibitory constant (Ki) of ~355 nM. In vitro exposure to Tivantinib inhibits constitutive c-Met phosphorylation in HT29 and MKN-45 cells, and HGF-induced c-Met phosphorylation in MDA-MB-231 and NCI-H441 cells with an IC50of 100 to 300 nM[1]. Tivantinib is a low-molecular-weight compound, and is the first in class orally available selective inhibitor of c-Met[2].

体内研究
(In Vivo)

Pharmacodynamically, the phosphorylation of c-Met in human colon xenograft tumors (HT29) is strongly inhibited by Tivantinib (ARQ 197), as assessed by a dramatic reduction of c-Met autophosphorylation 24 hours after a single oral dose of 200 mg/kg of Tivantinib. This same dosage in mice shows that tumor xenografts are exposed to sustained plasma levels of Tivantinib, consistent with the observed pharmacodynamic inhibition of c-Met phosphorylation and inhibition of proliferation of c-Met harboring cancer cell lines. A Cmaxof 5.73 μg/mL (13 μM), an area under the concentration-time curve of 12.1 μg/mL h, and a t1/2of 2.4 hours are measured. Plasma levels of Tivantinib 10 hours after dosing are determined to be 1.3 μM, >3-fold above the biochemical inhibitory constant of Tivantinib for c-Met[1].
