    Description: PLX4720 (PLX-4720; PLX 4720), a 7-azaindole/pyrrolopyridine-based vemurafenib derivative discovered by a structure-guided discovery approach, is a novel, potent and selective inhibitor of B-RafV600E mutant with potential antitumor activity. It inhibits B-RafV600E with an IC50 of 13 nM in a cell-free assay, and is 10-fold more selective for B-RafV600E over wild-type B-Raf. PLX-4720 potently inhibits ERK phosphorylation in tumor cell lines harboring B-RafV600E, induces cell cycle arrest and apoptosis in B-RafV600E-positive melanoma cells and causes tumor growth delays in B-RafV600E-dependent tumor xenograft models through oral administration.

    GeneralOral 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.
    Animal modelFemale athymic mice (NCr nu/nu) implanted s.c. with COLO205 cells, and SCID mice with 1205Lu or C8161 cells
    Formulation Suspended in vehicle (5% DMSO, 1% methylcellulose)
    Dosages5, 20, or 100 mg/kg
    AdministrationAdministered orally once or twice daily
