BI-2852 Chemical Structure

CAS No. 2375482-51-0

BI-2852 is a potent inhibitor of KRAS that binds with nanomolar affinity to a pocket between switch I and II on RAS. BI-2852 blocks all GEF, GAP, and effector interactions with KRAS, leading to inhibition of downstream signaling and an antiproliferative effect in the low micromolar range in KRAS mutant cells.

BI-2852 is a KRAS inhibitor that binds with nanomolar affinity to a pocket, thus far perceived to be “undruggable,” between switch I and II on RAS. BI-2852 is mechanistically distinct from covalent KRASG12C inhibitors because it binds to a different pocket present in both the active and inactive forms of KRAS. In doing so, it blocks all GEF, GAP, and effector interactions with KRAS, leading to inhibition of downstream signaling and an antiproliferative effect in the low micromolar range in KRAS mutant cells.[1]

Protocol

Cell Research:

[1]

- Collapse
  • Cell lines: NCI-H358 cells
  • Concentrations: 3 μM, 10 μM, 30 μM, 50 μM
  • Incubation Time: 0-24 hrs
  • Method:

    Cells are plated in 96 well plates (1500 cells per well) in the corresponding medium containing 10% FCS. The next day, compounds (Stock: 10 mM in 100% DMSO, including BI-2852), serially diluted in medium are added starting at 50 μM with 1:5 dilutions. Cells are incubated at 37 ℃ and 5% CO2 in a humidified atmosphere for 3 days. Quantification of living cells is performed using the cell titer glow reagent according to the manufacturer's recommendation. Luminescence is read in a 2030 VICTOR X5. Data are fitted by iterative calculation using a sigmoidal curve analysis program based on GraphPAD Prism with variable hill slope.

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
