1,2,4,5-BENZENETETRAMINE TETRAHYDROCHLORIDE Usage And Synthesis

Description

FAK inhibitor 14 (4506-66-5) is a selective focal adhesion kinase (FAK) inhibitor that displays no significant activity at a range of other kinases including EGFR, PDGFR and IGF-R.1 Prevents FAK autophosphorylation at Y397 (IC50 = 1 μM), promotes cell detachment and inhibits cell adhesion in vitro. FAK inhibitor 14 exhibits antiproliferative activity in a variety of human tumor cell lines in vitro and in breast cancer cells in vivo. Induces regression of pancreatic tumors2 and glioblastoma3. Displays antiangiogenic activity.4

Uses

FAK Inhibitor 14 directly blocks phosphorylation of focal adhesion kinase (FAK) in a dose- and time-dependent manner and has also shown breast tumor regression in vivo. It has been suggested that targeting the Y397 site of FAK with FAK Inhibitor 14 can be effectively used in cancer therapy.

Uses

FAK Inhibitor 14 has been used in the metastasis assay. It is also used to study its effect on bone morphogenetic protein 7 (BMP-7)-induced cell crawling and adhesion.

General Description

A cell-permeable tetraamine compound that is identified from a computer-aided molecular docking screening based on Fak Y397 interaction and is shown to inhibit FAK (Cat. No. 324876) autophosphorylation as well as its kinase activity toward paxillin phosphorylation both in cell-free kinase assays (IC₅₀<1 μM) and in BT474 breast cancer cultures, while exhibiting little activity against Pyk2 (Cat. No. 662067) autophosphorylation or the kinase activity of c-Raf, c-Src, EGFR, VEGFR-3, IGF-1, Met, PDGFR-α, Pyk2, and PI 3-K (p110δ/p85α). Reported to inhibit BT474 proliferation both in cultures in vitro (IC₅₀ ~10 μM) and in mice in vivo (~25% of no treatment controls on day 23; 30 mg/kg via 5 i.p/wk).

Biological Activity

Selective focal adhesion kinase (FAK) inhibitor that displays no significant activity at a range of other kinases including EGFR, PDGFR and IGF-RI. Prevents FAK autophosphorylation at Y397 (IC 50 = 1 μ M), promotes cell detachment and inhibits cell adhesion in vitro . Exhibits antiproliferative activity in a variety of human tumor cell lines in vitro and in breast cancer cells in vivo .

Biochem/physiol Actions

1,2,4,5-Benzenetetraamine tetrahydrochloride (FAK Inhibitor 14; Y15) is a cell-permeable, selective focal adhesion kinase (FAK) inhibitor. Focal adhesion kinase (FAK) is essential in regulating integrin signaling pathways responsible for cell survival, cell proliferation and motility. Phosphorylation of FAK tyrosine 397 (Y397) forms a high affinity binding site for the SH2 domain of the Src family kinases and PI3 kinase. FAK is overexpressed in a number of human tumors. 1,2,4,5-Benzenetetraamine tetrahydrochloride (FAK Inhibitor 14, Y15) blocks phosphorylation of Y397-FAK, which results in neuroblastoma cell detachment and apoptosis.
