PF-562271 besylate is a potent, ATP-competitive, reversible inhibitor of focal adhesion kinase (FAK) and Pyk2 used in biochemical, cell-based, and in vivo research. It is supplied as a 10 mM solution in DMSO and exhibits low-nanomolar activity against FAK and nanomolar activity against Pyk2.
- Potent inhibition of FAK and Pyk2 (FAK IC50 = 1.5 nM; Pyk2 IC50 = 13 nM).
- Supplied as a ready-to-use 10 mM solution in DMSO for in vitro assays.
- High reported purity suitable for research use (99.17%).
- Demonstrated antiproliferative activity across multiple cancer cell lines.
- Validated pharmacological effects in vivo, including inhibition of FAK phosphorylation.
