Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

BI-3406 (compound I-13) is a potent, selective and orally active inhibitor of the interaction between KRAS and Son of Sevenless 1 (SOS1) with IC50 of 5 nM. BI-3406 reduces the formation of GTP-loaded KRAS, and inhibits MAPK pathway signaling. BI-3406 exhibits anti-tumor activities.

(Cell-free assay)

5 nM

In vitro

BI-3406, a selective SOS1 inhibitor, enhanced the AMG 510-induced growth suppression in MIA PaCa-2 cells. Treatment with 5 µM BI-3406 following the excision of endogenous mutant KRAS abolishes both ERK and AKT activation, consistent with the inhibition of WT RAS signaling.^[1]

In vivo

BI-3406, a potent and selective SOS1-KRAS Interaction Inhibitor, is effective in KRAS-driven cancers through combined MEK inhibition.^[2]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines MIA PaCa-2, mT42 cells Concentrations 5 μM, 20 μM to 2 nM Incubation Time 4 days Method MIA PaCa-2 cells were seeded at 2,000 cells per well and treated 24 h after seeding with 5 μM BI-3406 or DMSO control and AMG 510 (from 5 μM to 0.1 nM). Cell viability was measured after 4 d with CellTiter-Glo. mT42 cells were seeded at 1,000 cells per well and treated with 4-OHT or DMSO control and BI-3406 in a dose–response manner (from 20 μM to 2 nM). Cell viability was measured using CellTiter-Glo Luminescence assay at day 4. FPC cell line mT42 cells were treated with 5 μM BI-3406, or DMSO vehicle control in the presence or absence of mutant KRAS by treatment with DMSO vehicle control or 4-OHT, respectively. Immunoblotting was performed for RAS pathways by phospho-ERK and phospho-AKT and the RSK1 substrate phospho-S6.
