Tos-PEG4-t-butyl ester (Tos-PEG4-Boc) is a PROTAC linker characterized by its PEG composition, crucial in synthesizing various PROTACs, including BI-3663, a selective PTK2/FAK PROTAC. Using cereblon ligands, it targets E3 ligases to degrade PTK2, exhibiting potent inhibitory activity with an IC50 of 18 nM[1].

Defactinib analogue-1 (Compound 7) serves as a ligand for the target protein FAK, and is utilized in the synthesis of PROTAC FAK degrader 1.

FAK-IN-22 (Compound 26) is an inhibitor of FAK, JAK3, and Aurora B, with IC50 values of 50.94 nM, 9.99 nM, and 0.49 nM, respectively, effectively suppressing tumorigenesis and metastasis in pancreatic ductal adenocarcinoma (PDAC). It inhibits proliferation in PANC-1 cells with an IC50 of 0.15 μM. FAK-IN-22 induces apoptosis and G2/M phase arrest in PANC-1 cells by inhibiting the FAK/PI3K/Akt signaling pathway.

MLK3-IN-1 (Compound 37) is a selective inhibitor of mixed-lineage kinase 3 (MLK3) with an IC50 of less than 1 nM. It also inhibits FAK with an IC50 of 15.5 μM. In both murine and human liver microsomes, MLK3-IN-1 demonstrates excellent metabolic stability.

1. Nitidine chloride has inhibitory effects on various tumors, such as renal cancer , breast cancer. 2. Nitidine chloride inhibits the proliferation of SMMC-7721 cells in vitro in a time- and dose-dependent manner and identifies efficacy in vivo in a mouse model of HCC.

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.

CYP1B1-IN-3 is a potent, selective inhibitor of CYP1B1, exhibiting IC50 values of 6.6 nM for CYP1B1, 347.3 nM for CYP1A1, and >10000 nM for CYP1A2. It also impedes cell migration and invasion, and inhibits the P-gp, AKT/ERK, FAK/SRC, and EMT pathways [1].

FAK-IN-9 (Compound 8f) is a potent, orally active FAK inhibitor with an IC50 value of 27.44 nM, effectively inducing apoptosis in triple-negative breast cancer (TNBC) cells [1].

Ganglioside GM2 is a component of the cell membrane's glycosphingolipid bilayer and a human tumor antigen (OFA-I-1). It accumulates and increases in models of Sandhoff disease, Niemann-Pick disease, and Tay-Sachs disease, among others. Ganglioside GM2 binds to the integrin β1 receptor, activating the FAK/Src/Erk-MAPK signaling pathway, thereby promoting tumor cell migration and invasion.
