Biological Activity

Description ML265 is a potent activator of PKM2 in both biochemical (AC50 = 92 nM) and cell-based assays with high selectivity over PKM1, PKR and PKL.
PKM2 [1]
In vitro

ML265 potently activates PKM2 in vitro with an AC50 = 92 nM and shows a high degree of selectivity over the other 3 pyruvate kinase isoforms. ML265 binds at the dimer-dimer interface of the PKM2 homotetramer. It is capable of activating PKM2 in cell lysate of pervanadate treated cells, which is a condition known to inhibit PKM2 activity through accumulation of phosphotyrosine peptides. ML265 significantly increased the doubling time of H1299 cells under hypoxic conditions, but interestingly showed no effect under normoxia[1].

In vivo

ML265 gave superior plasma concentrations that persisted at higher levels over the 24 hour study. ML265 also displayed good oral bioavailability, low clearance, a long half-life and good volume of distrubtion. The 7-week mouse xenograft model (H1299 mouse xenograft) showed that the activation of PKM2 with ML265 was able to significantly reduce tumor size and occurrence without showing signs of acute toxicity. [1].


Kinase Assay:


- Collapse

PKM2 activity assay:

Pyruvate kinase activity is measured by monitoring pyruvate-dependent conversion of NADH to NAD+ by lactate dehydrogenase (LDH). Briefly, for cell line experiments, the medium is replaced with fresh medium 1 hr prior to the start of treatment with DMSO or activator. Also, where indicated, 100 μM pervanadate is added 10 min prior to cell lysis. Cells are lysed on ice with RIPA buffer containing 2 mM DTT and protease inhibitors and clarified by centrifugation at 21,000 × g. 5 μL of the supernatant is used to assess pyruvate kinase activity. Pyruvate kinase activity was subsequently normalized for total protein content.

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 MSDS / 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.
