Biological Activity

Description Plixorafenib (PLX8394) is a next-generation, orally available, small-molecule BRAF inhibitor with IC50 values of 3.8 nM, 14 nM and 23 nM for BRAF(V600E), WT BRAF and CRAF respectively. It has potential antineoplastic activity.
Targets
BRAF(V600E) [2]
(Cell-free assay)		 BRAF [2]
(Cell-free assay)		 CRAF [2]
(Cell-free assay)
3.8 nM 14 nM 23 nM
In vitro

PLX8394 is a next-generation, orally available small-molecule BRAFi that does not induce the RAF/MEK/ERK paradoxical activation and blocks signaling from both monomeric BRAFV600 and dimeric BRAFnon-V600 protein[1].
In vivo

PLX8394 is a next-generation, orally available, small-molecule BRAF inhibitor with potential antineoplastic activity.
