Mechanism of Action

Features	A novel and potent inhibitor of the B-RAF^V600E oncoprotein.
Targets/IC₅₀/Ki	SRMS (Cell-free assay) 18 nM ACK1 (Cell-free assay) 19 nM B-Raf (V600E) (Cell-free assay) 31 nM C-Raf (Cell-free assay) 48 nM MAP4K5 (KHS1) (Cell-free assay) 51 nM FGR (Cell-free assay) 63 nM B-Raf (Cell-free assay) 100 nM LCK (Cell-free assay) 183 nM BRK (Cell-free assay) 213 nM NEK11 (Cell-free assay) 317 nM BLK (Cell-free assay) 547 nM Lyn B (Cell-free assay) 599 nM YES1 (Cell-free assay) 604 nM WNK3 (Cell-free assay) 877 nM MNK2 (Cell-free assay) 1.717 μM FRK (PTK5) (Cell-free assay) 1.884 μM CSK (Cell-free assay) 2.339 μM Src (Cell-free assay) 2.389 μM
In vitro	Vemurafenib (PLX4032) inhibits B-RAF^V600E, C-RAF, as well as wildtype B-RAF, with IC50 of 31 nM, 48 nM and 100 nM, respectively. This compound also inhibits several non-RAF kinases, including ACK1, KHS1, and SRMS, with IC50 of 18 nM to 51 nM. In melanoma cell lines, the inhibitory effect by it depends on B-RAF mutational status, because it potently inhibits those harboring B-RAF V600 mutants, including V600E, V600D, V600K, and V600R, but not wildtype or other mutants. The IC50 values on these cells, including MALME-3M, Colo829, Colo38, A375, SK-MEL28, and A2058, ranges from 20 nM to 1 μM. In these cells, Vemurafenib (0.1 μM to 30 μM) also inhibits the phosphorylation of both MEK1/2 and ERK1/2. It is highly effective in the treatment of melanoma, for its ability of inhibiting B-RAF^V600E. However, this compound displays limited effect in colon cancer patients that also carrying B-RAF^V600E oncoprotein. The reason for this is that, in colon cancer cells, B-RAF^V600E inhibition by it results in a rapid feedback EGFR activation, which compensates for the PLX4032-inhibited cell proliferation.
Kinase Assay	RAF kinase activity measurements
Kinase Assay	The kinase activities of wild-type RAF and mutants are determined by measuring phosphorylation of biotinylated-BAD protein in the presence of Vemurafenib (PLX4032). For each enzyme (0.01 ng), 20 μL reactions are carried out in 20 mM Hepes (pH 7.0), 10 mM MgCl₂, 1 mM DTT, 0.01% (v/v) Tween-20, 50 nM biotin-BAD protein, and 1 mM ATP at room temperature. Reactions are stopped at 5 min with 5 μL of a solution containing 20 mM Hepes (pH 7.0), 200 mM NaCl, 80 mM EDTA, 0.3% (w/v) bovine serum albumin (BSA). The stop solution also includes phospho-BAD (Ser112) antibody, streptavidin-coated donor beads, and protein A acceptor beads. The antibody and beads are pre-incubated in stop solution in the dark at room temperature for 30 min. The final dilution of antibody is 1/2000 and the final concentration of each bead is 10 μg/mL. The assay plates are incubated at room temperature for one hour and then are read on a PerkinElmer AlphaQuest reader. Mutant activities are the average of two different batches of purified protein assayed in duplicate in three different experiments.
In vivo	In B-RAF^V600E-mutant mice xenograft models, Vemurafenib (PLX4032) (6 mg/kg–20 mg/kg) inhibits tumor growth. In mice xenograft models of LOX, Colo829, and A375 cells, this compound (12.5 mg/kg–100 mg/kg) inhibits tumor growth and prolongs mice survival.

Frequently Asked Questions

Question 1:
How about its half-life?

Answer:
It was reported that this compound has a half-life of 57 hours.

Question 2:
When prepared in 4% DMSO/30% PEG 300/5% Tween 80/ddH2O solutions, it forms a pellet down the tube?

Answer:
When preparing this kind of vehicle, please dissolve it in DMSO clearly first. If it dissolves not readily, please sonicate and warm in the water bath at about 45 degree. Then add PEG and Tween. After they mixed homogeneously, then dilute with water.
