Biological Activity

Description MRTX-1257 is a potent, selective, irreversible, covalent and orally active inhibitor of KRAS G12C with IC50 of 900 pM for KRAS dependent ERK phosphorylation in H358 cells.
Targets
KRAS G12C [1]
()
KRAS dependent ERK phosphorylation [1]
(in H358 cells)
900 pM
In vitro

MRTX1257 demonstrates rapid, irreversible modification of GDP-bound recombinant KRAS G12C and suppresses ERK phosphorylation with an IC50 = 1 nM in the H358 cell line. In proteomics studies designed to assess global protein modification, MRTX1257 is shown to be highly selective for the targeted Cys12 of KRAS G12C versus other surface-exposed cysteine residues in NCI-H358 cells.[2]

In vivo

MRTX1257 exhibits 31% bioavailability in mouse, demonstrates near-complete inhibition of KRAS signaling in tumor tissue, and complete durable tumor regression in MIA PaCa-2 xenografts.[2]

Bio Calculators

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.
