“…Sorafenib has been reported to induce cell growth arrest and apoptosis in variety cancers including medulloblastomas [58], pancreatic cancer [59], glioblastoma [60], neuroblastoma [61], acute myeloid leukemia (AML) [62] and hepatocellular carcinoma (HCC) cells [63]. Our group has identified that sorafenib targets STAT3 in a kinase-independent pathway [19] and further generated a series of sorafenib derivatives (SC compounds such as SC-1, SC-40, SC-43, SC-49, SC-60 and SC-78) which lack activities on kinases but effectively induce cell apoptosis in cancers [19,64,65]. Sorafenib is a multiple kinase inhibitor targeting Raf-1 and other tyrosine kinases (e.g., VEGFR2, VEGFR3, Flt-3, PDGFR, and FGFR-1) [66,67].…”
