Colony survival assay in wild-type A549 cells treated with vehicle, 3.0 μM ME0328 or 500 nM KU58948 and pyridostatin.
Nat Commun, 2017, 8:15110.. ME0328 purchased from Selleck.
Combination drug treatment increased multinucleated giant cells via spindle microtubule alteration and cell cycle arrest. Immunofluorescent staining of BT-20 cell line after treatment with vinorelbine (NVB) or vinorelbine in combination with 5 μM of either ME0328 (NVB + ME) or olaparib (NVB + Olaparib) for 24 h. Cells were stained with Dapi for DNA (blue). α-tubulin for microtubules (green) and the merge with a 100× objective. Abundant multinucleated giant cells observed in cells treated with NVB + ME and NVB + Olaparib comparing with NVB alone.

|Description||ME0328 is a potent and selective PARP inhibitor with IC50 of 0.89 μM for PARP3, about 7-fold selectivity over PARP1.|
ME0328 is soluble, cell permeable, and metabolically stable in human liver microsomes and rat hepatocytes. ME0328 (10 μM) results in a significant delay of γH2AX-foci resolution by affecting ARTD3 in A549 and MRC5 cells without significant toxicity. 
Enzymatic Assays:Protein ADP-ribosylation is measured using hexahistidine-tagged ARTD proteins and recombinant histone proteins captured on 96-well Ni2+-chelating plates (5-PRIME). ADP-ribosylation reactions are initiated by addition of NAD+ (2% biotinylated), and modified reaction products are detected by chemiluminescence. Km values are estimated using plots of initial rates vs. NAD+ concentrations and linear curve fitting with GraphPad Prism. All compounds are dissolved in dimethyl sulfoxide (DMSO) to a stock concentration of 50 mM. Experiments to determine IC50 values are conducted with compound concentrations in the range between 10 nM and 450 μM with a DMSO concentration of 1% (v/v). Measurements are carried out at an NAD+ concentration below Km for each transferase. IC50 values are estimated using curve fitting with GraphPad Prism. Reported values represent means ± SE of the fits of the curves based on duplicate or triplicate experiments, each determined based on three replicates.

* 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.
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).
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 )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

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.
