Description: PF-562271 Besylate, also known as PF-562,271 and PF-271, is an orally bioavailable small molecule and ATP-competitive focal adhesion kinase (FAK) inhibitor with potential antineoplastic and antiangiogenic activities. PF-562271 inhibits the tyrosine kinase FAK, and to a lesser extent, proline-rich tyrosine kinase (PYK2), which may inhibit tumor cell migration, proliferation, and survival. Note: PF-562271 benzesulfonate is also called PF-562271 besylate.

Biological target: PF-562271 besylate is an ATP-competitive, reversible inhibitor of FAK and Pyk2 kinase, with an IC50 of 1.5 nM and 13 nM, respectively.
In vitro activity: Phosphorylated FAK (Y397) was highly expressed in primary human osteosarcoma tumor samples and was associated with osteosarcoma prognosis and lung metastasis. PF562271 greatly suppressed proliferation and colony formation in human osteosarcoma cell lines. In addition, treatment of osteosarcoma cell lines with PF562271 induced apoptosis and downregulated the activity of the protein kinase B/mammalian target of rapamycin pathway. PF562271 also impaired the tube formation ability of endothelial cells in vitro. Reference: Cancer Sci. 2017 Jul;108(7):1347-1356.
In vivo activity: Mouse bone marrow-derived macrophages (BMDMs) were obtained and treated with ATP or nigericin in the presence and absence of the clinical trial-tested Pyk2/FAK dual inhibitor, PF-562271. Consistent with findings in human monocyte-derived macrophages and THP-1 cells (Fig. 1A,B), the IL-1β secretion induced by ATP or nigericin was significantly blocked by pretreatment of BMDMs with PF-562271 (Fig. 6A). Next, this study analyzed the inhibition effect of PF-562271 on MSU-induced peritonitis (Fig. 6B). In vivo, MSU induced the production of IL-1β and the recruitment of cells (e.g., Gr-1 + F4/80− neutrophils and F4/80 + monocytes and macrophages) to the peritoneal cavity. However, pretreatment with PF-562271 significantly reduced the amounts of IL-1β and the numbers of recruited cells, compared to the DMSO control (Fig. 6C,D). These results suggest that the PF-562271-induced blockade of Pyk2 and FAK signaling reduces IL-1β production and the recruitment of inflammatory cells to the peritoneal cavity, thus alleviating the inflammatory symptoms in this in vivo model.

Formulation protocol: Tips for making stock solution: Due to its chemical nature, pure PF-562271 benzenesulfonate solid powder was found to have low solubility in common organic solvents and buffers. User may use the following information as reference when making stock solution: 1. PF562271 benzenesulfonate solubility data:(25°C): DMSO: ~ 0.4 mg/mL; Water ~ 0.8 mg/mL; Ethanol ~ 0.7 mg/mL. PBS (10 mM, pH 7.4) not soluble 2. Since PF562271 benzenesulfonate is not very soluble, when preparing stock solution, please always try small quantity first. After you get familiar with its solubility properties, you can scale up to make stock solution and do formulation. 3. The following method may help you to make high concentration stock solution: 5 mg PF562271 benzenesulfonate is mixed with 0.9 mL DMSO. The solution is sonicated for a few seconds till all big solid particles were disappeared. A cloudy solution was formed at this point. Then 0.1 mLwater was added and sonicated for a few seconds, which would give you a clear solution. The solution made by this method may be used as a stock solution. This stock solution can be diluted with water without precipitation. However, when it’s diluted with PBS buffer (10 mM, pH 7.4), the solution becomes cloudy, indicating that PF562271 was precipited from the solution. 4. Ward et al. had used 30% 2-hydroxypropyl-beta-cyclodextrin (HPCD) in 3 % dextrose to formulate PF562271. HPCD is a macrocyclic molecule, the inner core is more hydrophobic and would form complex with PF5622271. In other words, the PF562271 is encapsulated into the inner core of HPCD to form a complex, which would be more aqueous soluble. Many water insoluble drugs were formulated in this method.

Additional Information

Tips for making stock solution:
Due to its chemical nature, pure PF-562271 benzenesulfonate solid powder was found to have low solubility in common organic solvents and buffers. User may use the following information as reference when making stock solution:

1. PF562271 benzenesulfonate solubility data:(25°C): DMSO: ~ 0.4 mg/mL; Water ~ 0.8 mg/mL; Ethanol ~ 0.7 mg/mL. PBS (10 mM, pH 7.4) not soluble

2. Since PF562271 benzenesulfonate is not very soluble, when preparing stock solution, please always try small quantity first. After you get familiar with its solubility properties, you can scale up to make stock solution and do formulation.

3. The following method may help you to make high concentration stock solution: 5 mg PF562271 benzenesulfonate is mixed with 0.9 mL DMSO. The solution is sonicated for a few seconds till all big solid particles were disappeared. A cloudy solution was formed at this point. Then 0.1 mLwater was added and sonicated for a few seconds, which would give you a clear solution. The solution made by this method may be used as a stock solution. This stock solution can be diluted with water without precipitation. However, when it’s diluted with PBS buffer (10 mM, pH 7.4), the solution becomes cloudy, indicating that PF562271 was precipited from the solution.

4. Ward et al. had used 30% 2-hydroxypropyl-beta-cyclodextrin (HPCD) in 3 % dextrose to formulate PF562271. HPCD is a macrocyclic molecule, the inner core is more hydrophobic and would form complex with PF5622271.

(reference: Ward et al. Clinical experimental metastasis June 2013, vol 30, 5:579-594).

5. The stock solution (12.5 mg/ml) was made by dissolving the drug in a solution of 50% DMSO, 50% PEG-400 (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3087944.

6. PF562271 benzenesulfonate is less soluble in buffers with high pH (pH > 7). Therefore, we suggest to use water or acidic buffer for dilution.

7. Pure PF562271 has very low solubility, because of its chemical property, not because of the poor quality of our product. Molecule of PF562271 contains several basic nitrogen atoms, which will be porotonated in acdic media, and made the molecule more water soluble.
