Cdc7-IN-18 (compound 1-2) is a highly effective inhibitor of the CDC7 enzyme. It has an IC 50 value of 1.29 nM for the Cdc7/DBF4 enzyme. In addition, this compound exhibits strong antiproliferative activities, with an IC 50 value of 53.62 nM in COLO205 cells [1].
BMS-554417 is a novel inhibitor of IGF-IR, which inhibits IGF-IR and insulin receptor kinase activity and proliferation in vitro, and reduces tumor xenograft size in vivo. In a series of carcinoma cell lines, the IC50 for proliferation ranged from 120 nmol/L (Colo205) to >8.5 micromol/L (OV202). BMS-554417 treatment inhibited IGF-IR and insulin receptor signaling through extracellular signal-related kinase as well as the phosphoinositide 3-kinase/Akt pathway, as evidenced by decreased Akt phosphorylation at Ser473. At doses that inhibited proliferation, the compound also caused a G0-G1 arrest and prevented nuclear accumulation of cyclin D1 in response to LR3 IGF-I. In Jurkat T-cell leukemia cells, this agent triggered apoptotic cell death via the mitochondrial pathway. BMS-554417 was orally bioavailable and significantly inhibited the growth of IGF1R-Sal tumor xenografts in vivo. BMS-554417 is a member of a novel class of IGF-IR/insulin receptor inhibitors that have potential......
EBI-907 is a highly potent and orally efficacious B-RafV600E inhibitor. EBI-907 displays a low single-digit nanomolar activity (IC50 = 4.9 nM), which is >10-fold more potent than Vemurafenib (IC50 = 59 nM). EBI-907 also exhibits high potency in selectively inhibiting the proliferation of BRAF (V600E)-dependent cell lines (A375 and Colo205) and cellular Erk phosporylation, with superior activity to Vemurafenib. EBI-907, displaying potent activity against a number of important oncogenic kinases including BRK, FGFR1, c-Kit, and PDGFRb.
