產(chǎn)品描述: | PLX-4720 is a potent and selective inhibitor of B-RafV600E with IC50 of 13 nM in a cell-free assay, equally potent to c-Raf-1(Y340D and Y341D mutations), and 10-fold selectivity for B-RafV600E than wild-type B-Raf. |

B-RafV600E:13 nM (IC50);B-Raf:160 nM (IC50);BRK:130 nM (IC50);FRK:1300 nM (IC50);Csk:1500 nM (IC50);Src:1700 nM (IC50);FAK:1700 nM (IC50);FGFR:1900 nM (IC50);KDR:2300 nM (IC50);HGK:2800 nM (IC50);CSF1R:3300 nM (IC50);Aurora A:3400 nM (IC50);Raf |
體內(nèi)研究: |
Oral administration of PLX-4720 at 20 mg/kg/day induces significant tumor growth delays and regressions in B-RafV600E-dependent COLO205 tumor xenografts, without obvious adverse effects in mice even at dose of 1 g/kg. PLX-4720 at 100 mg/kg twice daily almost completely eliminates the 1205Lu xenografts bearing B-RafV600E, while has no activity against C8161 xenografts bearing wild-type B-Raf. The anti-tumor effects of PLX-4720 correlate with the blockade of MAPK pathway in those cells harboring the V600E mutation. PLX-4720 treatment at 30 mg/kg/day significant inhibits the tumor growth of 8505c xenografts by >90%, and dramatically decreases distant lung metastases |
