PF-06260933 2HCl 1883548-86-4_Others_Signaling Pathways_Products

PF-06260933 is a highly selective small-molecule inhibitor of MAP4K4 (Mitogen-activated protein kinase kinase kinase kinase 4) with IC50 values of 3.7 and 160 nM for cell-freel assay (kinase) and cell assay, respectively. It also inhibits MINK and TNIK with IC50 values of 8 and 13 nM, respectively. PF-06260933 has been reported to improve fasting hyperglycemia in mice. Recent studies in adipose tissue, pancreas, muscle, and macrophages suggest that MAP4K4, a serine/threonine protein kinase may be a viable target for antidiabetic drugs. As part of the evaluation of MAP4K4 as a novel antidiabetic target, PF-6260933.

Biological Activity

ln Vitro

In vitro activity: PF-06260933 is a highly selective small-molecule inhibitor of MAP4K4 with IC50 values of 3.7 and 160 nM for cell-freel assay (kinase) and cell assay, respectively. It also inhibits MINK and TNIK with IC50 values of 8 and 13 nM, respectively. PF-06260933 has been reported to improve fasting hyperglycemia in mice. Recent studies in adipose tissue, pancreas, muscle, and macrophages suggest that MAP4K4, a serine/threonine protein kinase may be a viable target for antidiabetic drugs. As part of the evaluation of MAP4K4 as a novel antidiabetic target, PF-6260933.

Kinase Assay: Aortas were lysed in 1% NP-40, 50 mM Tris pH 7.4, 150 mM NaCl, 50 mM EDTA with 1 × HALT protease and phosphatase inhibitors (Thermo Scientific) and immunoprecipitated with Bethyl MAP4K4 antibodies (503 A; 1 μg) or normal rabbit IgG (Cell Signaling 2729; 1 μg). Myelin basic protein (MBP) (1 μg) and 10 μCi of [γ-32P]ATP were added to the immunoprecipitates and incubated for 30 min at 30 °C in kinase buffer (20 mM HEPES, 10 nM MgCl2, 1 mM dithiothreitol (DTT) and protease and phosphatase inhibitor cocktail). Samples were separated by 12% SDS–polyacrylamide gel electrophoresis and visualized by autoradiography.

Cell Assay: HUVECs are maintained in EGM2 media at 37°C and 5% CO2. HUVECs or peritoneal macrophages are treated with vehicle or PF-06260933 in vitroto determine whether pharmacological inhibition of MAP4K4 alteres MAPK signalling in response to TNF-α

ln Vivo

At 6–8 weeks of age, male flox/flox and flox/flox/cre+ littermates were injected with 1 mg tamoxifen per day in corn oil for 5 days. At 5–6 weeks of age (KD mice) or 2 weeks after tamoxifen injection (flox mice), the mice were fed chow or WD (0.2% cholesterol, TD 88137, Harlan Laboratories) for 16 weeks. Compound PF-06260933 (10 mg kg−1, dissolved in dH2O) was orally administered to 8–10-week-old male ApoE−/− mice twice daily for 6 weeks. Ldlr−/− male mice (B6.129S7-Ldlrtm1Her/J, Jackson Laboratories, 8–10 weeks old) were placed on HFD (1.25% cholesterol, TD96121, Harlan Laboratories) for 10 weeks before drug administration. Compound PF-06260933 was administered to male 8–10-week-old Ldlr−/− mice as above for 10 weeks. Oral administration of water was used as vehicle control in all studies. Mice were euthanized by CO2 inhalation followed by bilateral pneumothorax. No statistical methods were used to predict sample size, no randomization was performed and the investigations were not blinded during the knockout animal analyses, but were blinded during the drug treatment analyses.

Solubility (In Vivo)

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.

Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

(Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	2.7050 mL	13.5252 mL	27.0504 mL

	10 mM	0.2705 mL	1.3525 mL	2.7050 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
