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.
