FAK

PTK2 protein tyrosine kinase 2; PTK2; Focal adhesion kinase

FAK (Focal Adhesion Kinase or PTK2) is a non-receptor and non-membrane associated protein tyrosine kinase that is activated at the sites of cell-matrix adhesions and integrin clustering by auto-phosphorylation (at Tyr397), Src, and other tyrosine kinases. FAK mediates integrin-based cell signaling by transferring signals regulating cell migration, adhesion, and survival from the extracellular matrix to the cytoplasm.

FAK is overexpressed in many tumors, including those derived from the head and neck, colon, breast, prostate, liver, and thyroid. Furthermore, FAK overexpression is highly correlated with an invasive phenotype in these tumors. Inhibition of FAK signaling by overexpression of dominant-negative fragments of FAK reduces invasion of glioblastomas and ovarian cancer cells. FAK therefore represents an important target for the development of anti-neoplastic and anti-metastatic drugs.

    Stellettin B
    Inhibitor
    Stellettin B is a triterpenoid compound that can be isolated from the marine sponge Jaspis stellifera. Stellettin B induces G1 phase arrest, apoptosis, and autophagy in human non-small cell lung cancer A549 cells by blocking the PI3K/Akt/mTOR pathway. Stellettin B can reduce the migration and invasion of liver cancer cells by decreasing the activation of the MAPK and FAK/PI3K/AKT/mTOR signaling pathways. Stellettin B can be used in the study of various tumors.

    proMMP-9 inhibitor-3c
    Inhibitor
    proMMP-9 inhibitor-3c (compound 3c) is a potent proMMP-9 inhibitor. proMMP-9 inhibitor-3c is specific for binding to the proMMP-9 hemopexin-like domain (Kd=320 nM). proMMP-9 inhibitor-3c disruption of MMP-9 homodimerization prevents association of proMMP-9 with both α4β1 integrin and CD44 and results in the dissociation of EGFR. This disruption results in decreased phosphorylation of Src and its downstream target proteins focal adhesion kinase (FAK) and paxillin (PAX).

    Masitinib (Standard)
    Inhibitor
    Masitinib (Standard) is the analytical standard of Masitinib. This product is intended for research and analytical applications. Masitinib (AB1010) is a potent, orally bioavailable, and selective inhibitor of c-Kit (IC50=200 nM for human recombinant c-Kit). It also inhibits PDGFRα (IC50s=540/800 nM), Lyn (IC50= 510 nM for LynB), Lck, and, to a lesser extent, FGFR3 and FAK. Masitinib (AB1010) has anti-proliferative, pro-apoptotic activity and low toxicity.
