Vemurafenib (PLX4032; RG7204) is a first-in-class, selective, potent inhibitor of B-RAF kinase, with IC50s of 31 and 48 nM for RAFV600E and c-RAF-1, respectively.
Vemurafenib (PLX4032) selectively blocks the RAF/MEK/ERK pathway in BRAF mutant cells[1]. RG7204 is a potent inhibitor of proliferation in those expressing RAFV600E but not BRAFWT in 17 melanoma cell lines. Vemurafenib (RG7204) induces MEK and ERK phosphorylation at high concentrations in CHL-1 cells[2]. Ectopic expression of EGFR in melanoma cells is sufficient to cause resistance to PLX4032[3].
Vemurafenib (PLX4032, 20, 25, 75 mg/kg, p.o.) causes dose-dependent inhibition of tumor growth, with higher exposures resulting in tumor regression of BRAF mutant xenografts[1]. RG7204 (12.5, 25, and 75 mg/kg, p.o.) significantly inhibits tumor growth and induced tumor regression in mice bearing LOX tumor xenografts[2].

|
Applications |
In melanoma cell lines, RG7204 was a potent inhibitor of proliferation in those expressing BRAFV600E but not BRAFWT. RG7204 also potently inhibited proliferation of melanoma cell lines expressing other codon 600 BRAF mutations (V600D, V600 K, and V600R). |
| Animal experiment: | |
|
Animal models |
Athymic nude mice |
|
Dosage form |
100 mg/kg bid; oral taken. |
|
Applications |
In mice bearing Colo829 tumor xenografts, RG7204 at 100 mg/kg bid for 21 days showed greatly improved antitumor activity compared both with vehicle (P = 0.001) at the end of the study on day 38 after the tumor cell implant. There was complete tumor regression in all 10 mice treated with RG7204 by the end of the study. Survival in the mice treated with RG7204 was significantly better than in those treated with vehicle (P = 0.0008). |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
