Product Description

Biological Activity

Description SB590885 is a potent B-Raf inhibitor with Ki of 0.16 nM in a cell-free assay, 11-fold greater selectivity for B-Raf over c-Raf, no inhibition to other human kinases.
Targets B-Raf [1]
(Cell-free assay)
IC50 0.16 nM(Ki)
In vitro SB590885 displays significant selectivity for B-Raf over c-Raf with Ki of 0.16 nM over 1.72 nM. SB-590885 is a more potent inhibitor than the previously described Raf/VEGFR kinase inhibitor BAY 439006 (Ki = 38 nM for mutant B-Raf, 6 nM for c-Raf). SB590885 displays potent selectivity over 46 other kinases. Unlike the multi-kinase inhibitor BAY43-9006, SB590885 stabilizes the oncogenic B-Raf kinase domain in an active configuration. In Colo205, HT29, A375P, SKMEL28, and MALME-3M cells expressing oncogenic B-RafV600E, SB590885 treatment potently inhibits ERK phosphorylation with EC50 of 28 nM, 58 nM, 290 nM, 58 nM, and 190 nM, respectively, and consistently, inhibits the proliferation with EC50 of 0.1 μM, 0.87 μM, 0.37 μM, 0.12 μM, and 0.15 μM, respectively. SB590885 decreases anchorage-independent growth of melanoma cell lines in a BRAF mutant-selective manner. [1] SB590885 displays high affinity for B-Raf with Kd of 0.3 nM. [2] Most of the melanoma cell lines that harbor the BRAF V600E mutation and lack CDK4 mutations (451Lu, WM35, and WM983) are highly sensitive to SB590885 with IC50 of <1 μM. Increased levels of cyclin D1 resulting from genomic amplification mediate SB590885 resistance in B-Raf V600E-mutated melanomas. [3]
In vivo Administration of SB590885 potently decreases tumorigenesis in murine xenografts established from mutant B-Raf-expressing A375P melanoma cells, and modestly inhibits tumor growth. [1]
Features Displays significant selectivity for B-Raf over c-Raf.

Protocol(Only for Reference)

Cell Assay: [1]

Cell lines Colo205, HT29, A375P, SKMEL28, and MALME-3M
Concentrations Dissolved in DMSO, final concentrations ~10 μM
Incubation Time 72 hours
Method Cells are treated with increasing concentrations of SB590885 and incubated for 72 hours. Viable cells are quantified using CellTiter-Glo reagent and luminescence detection on a Victor 2V plate reader. Cells are prepared for cell cycle analysis on a Becton Dickinson FACScan. Data is acquired and analyzed using CellQuest v3.3 software.

Animal Study: [1]

Animal Models Female nude mice injected s.c. with of A375P cells
Formulation Dissolved in vehicle [2% N,N-dimethylacetamide, 2% Cremophor EL, and 96% acidified water (pH f4-5)]
Dosages 50 mg/kg/day
Administration Injection i.p.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
