Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Raf ^[1]
In vitro	PLX7904 is able to efficiently inhibit activation of ERK1/2 in mutant BRAF melanoma cells but does not hyperactivate ERK1/2 in mutant RAS-expressing cells. Consistent with ERK1/2 re-activation driving the re-acquisition of malignant properties, this compound promotes apoptosis and inhibits entry into S phase and anchorage-independent growth in mutant N-RAS mediated vemurafenib-resistant cells. This chemical is also evaluated in the human SCC cell line A431 and the human breast adenocarcinoma cell line SKBR3 as these cells achieve MAPK pathway activation by upstream signals feeding into RAS (through overexpression of epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2), respectively)^[1]^[2].
In vivo	PLX7904 inhibits the COLO205 xenograft growth in eight mice per group^[1].
