| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

PF-562271 is a potent, ATP-competitive and reversible inhibitor of both focal adhesion kinase (FAK), a non-receptor tyrosine kinase involved in a variety of cellular events, and proline-rich tyrosine kinase 2 (Pyk2), an FAK homolog containing 48% amino acid identity, with half maximal inhibitory concentration (IC50) of 1.5 nmol/L and 14 nmol/L respectively. As a potential therapeutic agent either alone or in combination with other agents for the treatment of cancer, PF-562271 has been reported to effectively inhibit the proliferation of tumors in both xenograft and transgenic mouse models, in which it dose-dependently inhibits FAK phosphorylation in tumor-bearing mice with half maximal effective concentration (EC50) of 93 ng/mL.

Safety, pharmacokinetic, and pharmacodynamic phase I dose-escalation trial of PF-00562271, an inhibitor of focal adhesion kinase, in advanced solid tumors.[Pubmed:22454420]
J Clin Oncol. 2012 May 1;30(13):1527-33.
PURPOSE: PF-00562271 is a novel inhibitor of focal adhesion kinase (FAK). The objectives of this study were to identify the recommended phase II dose (RP2D) and assess safety and tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and antitumor activity of PF-00562271. PATIENTS AND METHODS: Part 1 was a dose escalation without and with food. Part 2 enrolled specific tumor types in an expansion at the RP2D and also assessed the effect of PF-00562271 on single-dose midazolam PK in a subgroup of patients. RESULTS: Ninety-nine patients (median age, 60 years; 98% with Eastern Cooperative Oncology Group performance status of 0 or 1) were treated in 12 fasting and three fed cohorts. The 125-mg twice-per-day fed dose was deemed the maximum-tolerated dose (MTD) and RP2D. Grade 3 dose-limiting toxicities included headache, nausea/vomiting, dehydration, and edema. Nausea was the most frequently observed toxicity (60% of patients, all grades 1 or 2 at RP2D). PF-00562271 exposure increased with increasing dose; serum concentration-time profiles showed characteristic nonlinear disposition. Steady-state exposures were reached within 1 week. On coadministration, geometric mean values of midazolam maximal observed serum concentration and area under the serum concentration-time curve increased by 60% and more than two-fold, respectively. Of 14 patients evaluable by [(18)F]fluorodeoxyglucose positron emission tomography in the expansion cohorts, seven metabolic responses were observed. With conventional imaging, 31 patients had stable disease at first restaging scans, and 15 of these remained stable for six or more cycles. CONCLUSION: The MTD and RP2D of PF-00562271 is 125 mg twice per day with food. PF-00562271 displayed time- and dose-dependent nonlinear PK and is likely a potent CYP 3A inhibitor. This first-in-class study supports further investigation of FAK as a promising therapeutic target.
