FAK-IN-4 (Compound 7d) exhibits anticancer activities by inducing cell apoptosis and is a potential inhibitor of FAK [1].

FAK-IN-8 (compound 5h), a FAK inhibitor with an IC50 of 5.32 μM, exhibits potent anti-proliferative activity, making it suitable for use in cancer research [1].

FAK-IN-3 is a potent inhibitor of adherens spot kinase (FAK). FAK-IN-3 reduces migration and invasion of PA-1 cells and inhibits the expression of MMP-2 and MMP-9. FAK-IN-3 inhibits tumor growth and metastasis with no significant adverse effects. FAK-IN-3 has shown investigational potential in ovarian cancer.

PH11 is a novel Focal Adhesion Kinase (FAK) inhibitor. PH11 restores TRAIL apoptotic pathway in PANC-1 cells through down-regulation of c-FLIP via inhibition of FAK and the phosphatidylinositol-3 kinase (PI3K) AKT pathways. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) emerges as one of the most-promising experimental cancer therapeutic drugs and is currently being tested in clinical trials. However, both intrinsic and acquired resistance of human cancer cells to TRAIL-induced apoptosis poses a huge problem in establishing clinically efficient TRAIL therapies.

Azurin (50-77) is a peptide fragment derived from the copper-containing bacterial protein azurin, present in P. aeruginosa. It exhibits properties that regulate the cell cycle, inhibit cancer proliferation, and manage angiogenesis, proving its potential as an anticancer agent. Specifically, this compound acts as a VEGFR2 inhibitor with an IC20 of approximately 10.7 µM. At a concentration of 20 µM, it effectively induces cell cycle arrest at the G2 M phase in MCF-7 breast cancer cells, while a higher concentration of 50 µM significantly reduces the proliferation of both MCF-7 and ZR-75-1 breast cancer cell lines. Furthermore, Azurin (50-77) impedes VEGF-A-induced capillary tube formation with an IC50 of 12 µM, and alters the cellular and extracellular levels of critical signaling and structural proteins such as F-actin, focal adhesion kinase (FAK), paxillin, and platelet endothelial cell adhesion molecule-1 (PECAM-1) in human umbilical vein endothelial cells (HUVECs) at a concentration of 25 µM. Demonstrating its efficacy in vivo, Azurin (50-77) administered at 10 mg kg per day notably reduces tumor volume in an MCF-7 mouse xenograft model, highlighting its therapeutic potential.

FAK-IN-20 (Compound 7b), a potent FAK inhibitor, demonstrates an IC 50 of 0.27 nM and exhibits anticancer properties. This compound arrests the cell cycle in the G2 M phase and induces cell apoptosis (apoptosis) through the generation of ROS [1].
