Su-11274 is a selective Met tyrosine kinase inhibitor with IC50 of 10 nM. Su-11274 increases tumorigenicity and enriched for melanoma-initiating cells by bioenergetic modulation. Su-11274 suppresses proliferation and motility of pancreatic cancer cells. Su-11274 enhances the response of the prostate cancer cell line DU145 to ionizing radiation. Su-11274 exhibits a selective inhibition pattern toward different receptor mutated variants.

How to use
Su-11274 exhibits greater than 50-fold selectivity for Met versus Flk and more than 500 times selectivity versus other tyrosine kinases such as FGFR-1, c-src, PDGFbR, and EGFR. Su-11274 inhibits the phosphorylation of key regulators of the PI3K pathway, including AKT, FKHR, or GSK3β. Su-11274 treatment inhibits the growth of TPR-MET-transformed BaF3 cells in a dose-dependent manner with IC50 of < 3 μM in the absence of interleukin 3, without growth inhibition of BaF3 cells transformed by other oncogenic tyrosine kinases, including BCR-ABL, TEL-JAK2, TEL-ABL, and TEL-PDGFβR. In addition to cell growth, Su-11274 treatment significantly inhibits the migration of BaF3. TPR-MET cells by 44.8% and 80% at 1 μM and 5 μM, respectively. Su-11274 inhibits HGF-dependent phosphorylation of Met as well as HGF-dependent cell proliferation and motility with an IC50 of 1-1.5 μM. In H69 and H345 cells which have functional Met receptor, Su-11274 inhibits the HGF-induced cell growth with IC50 of 3.4 μM and 6.5 μM, respectively. Su-11274 induces G1 cell cycle arrest with cells in G1 phase increased from 42.4% to 70.6% at 5 μM, and induces caspase-dependent apoptosis by 24% at 1 μM. Su-11274 inhibits cell viability in c-Met-expressing non-small cell lung cancer (NSCLC) cells with IC50 values of 0.8-4.4 μM, and abrogates hepatocyte growth factor-induced phosphorylation of c-Met and its downstream signaling.
