| Sorafenib, p-Toluenesulfonate Salt | Sorafenib (Bay 43-9006) is a novel bi-aryl urea compound that inhibits cell proliferation by targeting the ERK pathway and angiogenesis by targeting the receptor tyrosine kinases VEGFR-2 and PDGFR-b and their associated signaling cascades. Although sorafenib was initially developed as a Raf kinase inhibitor (IC50=6nM), it has since been shown to have activity against many receptor tyrosine kinases involved in tumorigenesis and angiogenesis including FGFR-1, wt BRAF and V599E mutant BRAF, as well as members of the so-called "split kinase" family: VEGFR-2, VEGFR-3, PDGFR-b, c-KIT, and Flt3. However, sorafenib is not active against erbB1, erbB2, ERK-1, MEK-1, EGFR, HER-2, IGFR-1, c-MET, c-yes, PKB, PKA, cdk1/cyclinB, PKC, and pim-1.

| STAT3 Control Cell Extracts (Signal Transducer and Activator of Transcription 3, Acute-phase Response Factor, APRF) | Stat3 is a key signaling molecule for many cytokines and growth-factor receptors and is required for murine fetal development. Additionally, Stat3 is constitutively activated in a number of human tumors and possesses oncogenic potential and anti-apoptotic activities. Stat3 is activated by tyrosine phosphorylation at Tyr705, which induces dimerization, nuclear translocation and DNA binding. Transcriptional activation seems to be regulated by serine phosphorylation at Ser727, apparently via the MAPK or mTOR pathways. Stat3 isoform expression appears to reflect biological function: the relative expression levels of Stat3alpha (86kD) and Stat3beta (79kD) depend on cell type, ligand exposure or maturation stage of the cells. It is notable that Stat3beta lacks the serine phosphorylation site within the C-terminal transcriptional activation domain. Group: Biologicals. Grades: Lysate. Pack Sizes: 10Blots.

US Biological Life Sciences. | Worldwide |
| Staurosporin | Staurosporine is an alkaloid isolated from the culture broth of Streptomyces staurospores and is a super-potent, cell permeable PKC inhibitor (IC50=0.7); at higher concentrations Staurosporine inhibits other protein kinases: CDK2/cyclin A (IC50=7uM) and CDK4/cyclin D (IC50=3-10uM). At a concentration of 50-100nM it is a functional neurotrophins agonist promoting neurite outgrowth in neuroblastoma, pheochromocytoma and brain primary neuronal cultures. Staurosporine inhibits a variety of kinases including PKA, PKG, MLCK, CaMK, tyrosine kinases, and phosphorylase kinase. This compound displays selectivity toward the PKC isoforms, inhibiting PKCα, PKC β, PKCγ, PKCδ, and PKCε, but not PKC?, and induces PKC translocation. Staurosporine also inhibits topoisomerase II directly by interaction with the ATP binding site, augments PMA-induced ornithine decarboxylase, and activates a bcl-2-regulated apoptosis pathway.
