PF-04217903 is an orally active, highly selective ATP-competitive c-Met kinase inhibitor with a K_i value of 4.8 nM and a K_d value of 4.5 nM. PF-04217903 blocks c-Met and HGF signaling pathways, inhibits MET phosphorylation, and blocks downstream MAPK, PI3K/AKT and PLCγ1 pathways. PF-04217903 suppresses tumor proliferation, survival, migration, invasion, angiogenesis and metastasis, induces apoptosis, and enhances efferocytosis, Annexin A1 expression and resolution of inflammation. PF-04217903 retains activity against several c-Met mutants (M1131T, V1220I, H1094R). PF-04217903 increases the incidence of subarachnoid hemorrhage and reduces survival rate without altering aneurysm formation, and also prevents lymph node metastasis induced by VEGF inhibition. PF-04217903 is applicable to research related to tumors (pancreas, stomach, lung, brain, colon, breast, kidney, melanoma, etc.), intracranial aneurysms and inflammatory diseases (gouty arthritis, neutrophilic pleuritis).

PF-04217903 (1 μM) shows biochemical inhibition of IGF1R in kinase selectivity screens, but does not inhibit IGF1R activity in cell-based assays^[8].
PF-04217903 (30 min) potently inhibits wild-type c-Met (K_i = 6.5-7.4 pM) and most oncogenic c-Met mutants, but exhibits drastically reduced potency against c-Met^Y1230C, c-Met^Y1230H, and c-Met^D1228H mutants, and no measurable inhibition of c-Met^D1228H^[9].

Real Time qPCR^[3]

Cell Line:

human aortic endothelial cells, human aortic smooth muscle cells, THP-1 human monocyte cells
Concentration:

6 μg/mL
Incubation Time:

1 h (pre-incubation); 3 hs (LPS treatment)
Result:

Abolished the HGF-mediated attenuation of VCAM-1 and E-selectin expression induced by LPS in human aortic endothelial cells, such that VCAM-1 and E-selectin levels were similar to those in cells treated with LPS alone.
Showed no significant effects on TNF-α, IL-1β, MCP-1, COX-1, COX-2, TGF-β, or ICAM-1 expression in human aortic endothelial cells.
Had no significant effect on any measured inflammatory molecule expression in human aortic smooth muscle cells and THP-1 monocytes when combined with HGF and LPS, compared to LPS alone or HGF plus LPS.

Western Blot Analysis^[4]

Cell Line:

murine primary ATCs and Met-amplified/Met-diploid recurrent murine ATCs
Concentration:

10, 50, 200 and 1000 nM
Incubation Time:

1 h
Result:

Inhibited phosphorylation of Met (Y1234/Y1235) only in Met-amplified recurrent ATC cell lines 34286 and 36934, with reduced pMet visible at doses as low as 10 nM.
Blocked downstream phosphorylation of Akt (S473) and Erk (T202/Y204) in these Met-amplified lines, but had no effect on pMet, pAkt, or pErk levels in primary ATC or Met-diploid recurrent ATC cell lines.

Apoptosis Analysis^[5]

Cell Line:

Primary human peripheral blood neutrophils
Concentration:

30 µM
Incubation Time:

1, 2 and 6 h
Result:

Selective HGF/MET inhibition blocked MET phosphorylation in human primary neutrophils stimulated by LPS/HGF or MSU crystals.
MET blockade increased neutrophil apoptosis at 6 hours, evidenced by chromatin condensation and nuclear fragmentation.
This apoptosis was caspase-dependent, as zVAD-fmk abolished the effect at 2 hours.
Mechanistically, MET suppression elevated cleaved caspase-3 and reduced Bcl-xL expression.
The effect was neutrophil-specific, as MET inhibition did not induce macrophage apoptosis in vivo.
Additionally, MET blockade reversed the pro-survival effect of combined LPS/HGF stimulation.

Western Blot Analysis^[8]

Cell Line:

parental GTL16 gastric carcinoma cells, METi-resistant GTL16R1, GTL16R3 clones
Concentration:

200 nM (single agent); 2.5 μM (combination treatment assays)
Incubation Time:

4 h (single agent)
Result:

Inhibited phosphorylation of c-Met Y1349 in all three cell lines, despite moderately increased total c-Met protein levels in treated samples.
Completely inhibited ERK phosphorylation in parental GTL16 cells, but only caused a slight decrease in ERK phosphorylation in GTL16R1 and GTL16R3 clones.
Reduced AKT S473 phosphorylation to ~10% of baseline levels in all cell lines.
When combined with 200 nM RAFi, further inhibited ERK phosphorylation in GTL16R1 and GTL16R3 to 38% and 10.5% of untreated GTL16 levels, respectively.

Its activity is mediated by inhibition of the c-Met signaling pathway, reduction of tumor cell proliferation, induction of apoptosis, anti-angiogenic effects, and decreased secretion of pro-angiogenic cytokines^[6].
As a monotherapy, PF-04217903 (50 mg/kg; p.o.; once daily; for 21 consecutive days) achieves a 40% TGI in a c-Met-overexpressing HT29 xenograft model, while RON shRNA alone achieves a 52% TGI; due to the blockade of the AKT signaling pathway and the induction of tumor cell apoptosis, the efficacy of the combination therapy is enhanced to a 77% TGI^[6].

Stock Solution Working Solution

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

Protocol 3

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

Solubility: ≥ 2 mg/mL (5.37 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
