Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Merestinib (LY2801653) is a type-II ATP competitive, slow-off inhibitor of Met (c-Met) tyrosine kinase with a dissociation constant (Ki) of 2 nM, a pharmacodynamic residence time (Koff) of 0.00132 min(-1) and t1/2 of 525 min. Merestinib (LY2801653) also inhibits MST1R, AXL, ROS1, MKNK1/2, FLT3, MERTK, DDR1 and DDR2 with IC50 of 11 nM, 2 nM, 23 nM, 7 nM, 7 nM, 10 nM, 0.1 nM and 7 nM, respectively.

In vitro

LY2801653 demonstrates in vitro effects on MET pathway-dependent cell scattering and cell proliferation. It demonstrates more potent anti-proliferative activity in cell lines with MET gene amplification (MKN45, Hs746T and H1993) than the cell lines without MET gene amplification (U-87MG, KATO-III). LY2801653 also maintains potency against 13 MET variants, each bearing a single-point mutation. It is found to have potent activity against several other receptor tyrosine oncokinases including MST1R, FLT3, AXL, MERTK, TEK, ROS1, DDR1/2 and against the serine/threonine kinases MKNK1/2. The mean IC50 value of LY2801653 for inhibition of MET auto-phosphorylation in HGF-stimulated H460 cells is 35.2±6.9 nM and the IC50 for MET auto-phosphorylation in S114 cells is 59.2 nM[1].
In vivo

LY2801653 shows in vivo anti-tumor effects in MET amplified (MKN45), MET autocrine (U-87MG, and KP4) and MET over-expressed (H441) xenograft models; and in vivo vessel normalization effects. It is able to induce vessel normalization in xenograft tumors. Among the species studied, LY2801653 has the shortest elimination half life in mice of 2.9 h, compared with 14.3 h in non-human primate. LY2801653 is currently in phase 1 clinical testing in patients with advanced cancer[1].

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    DU145 cells

  • Concentrations

    0.01-10 μM

  • Incubation Time

    48 h

  • Method

    2×103 DU145 cells/well on poly-D-lysine 96-well black/clear plates are treated with LY2801653 (in 0.4 % DMSO), immediately followed by the addition of human HGF (20 ng/ml), and incubated for 48 h at 37 °C. 2 % formaldehyde fixed cells are stained with AlexaFluor 488 Phalloidin and counterstained with Propidium Iodide. Colony counts are quantified on Acumen Explorer™ laser-scanning fluorescence microplate cytometer. A colony is defined as≥4 cells.
Animal Study:

  • Animal Models

    Athymic nude mice and CD-1 nude mice

  • Dosages

    0.75 mg/kg to 100 mg/kg

  • Administration

    oral administration
