生物活性

製品説明 Vemurafenib (RG7204, RO5185426,PLX4032) is a novel and potent inhibitor of B-RafV600E with IC50 of 31 nM in cell-free assay. 10-fold selective for B-RafV600E over wild-type B-Raf in enzymatic assays and the cellular selectivity can exceed 100-fold. Vemurafenib (PLX4032, RG7204) induces autophagy.
in vitro Vemurafenib (PLX4032) inhibits B-RAFV600E, 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. [1] In melanoma cell lines, its inhibitory effect 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, it (0.1 μM to 30 μM) also inhibits the phosphorylation of both MEK1/2 and ERK1/2. [2] It is highly effective in the treatment of melanoma, for its ability of inhibiting B-RAFV600E. However, this compound displays limited effect in colon cancer patients that also carrying B-RAFV600E oncoprotein. The reason for this is that, in colon cancer cells, B-RAFV600E inhibition by it results in a rapid feedback EGFR activation, which compensates for the PLX4032-inhibited cell proliferation. [3]
in vivo Vemurafenib (PLX4032) inhibits tumor growth in B-RAFV600E-mutant mice xenograft models at doses of 6 mg/kg–20 mg/kg. [1] In mice xenograft models of LOX, Colo829, and A375 cells, it also inhibits tumor growth and prolongs survival at doses of 12.5 mg/kg–100 mg/kg. [2]
特徴 A novel and potent inhibitor of the B-RAFV600E oncoprotein.

キナーゼアッセイ RAF kinase activity measurements
The kinase activities of wild-type RAF and mutants are determined by measuring phosphorylation of biotinylated-BAD protein. 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.

実験の流れ

Cellular proliferation is evaluated by MTT assay. Briefly, cells are plated in 96-well microtiter plates at a density of 1000 to 5000 cells per well in a volume of 180 μL. Vemurafenib (PLX4032) is prepared at 10 times the final assay concentration in media containing 1% DMSO. Twenty-four hours after cell plating, 20 μL of the appropriate dilution of this compound are added to plates in duplicate. The plates are assayed for proliferation 6 days after the cells are plated. Percent inhibition is calculated and the IC50 is determined from the regression of a plot of the logarithm of the concentration versus percent inhibition.
