Description
VS-4718 is an inhibitor of focal adhesion kinase (FAK). It blocks FAK Tyr-397 phophorylation in vivo and exhibits antitumor activity in orthotopic breast carcinoma models in mice. VS-4718 also significantly reverses ATP-binding cassette transporter ABCB1 and ABCG2-mediated multi-drug resistance. It shows potential in combination with other therapies to overcome multidrug resistance in ABCB1 or ABCG2-overexpressing cancer cells.
