Product Introduction

Bioactivity

Description	ME0328 is a potent, selective PARP inhibitor with an IC50 of 0.89 μM for PARP3, showing approximately 7-fold selectivity over PARP1.
Targets&IC50	PARP3:0.89 μM, ARTD6/TNKS2:34.3 μM, ARTD2/PARP2:10.8 μM, ARTD1/PARP1:6.3 μM, ARTD5/TNKS1:47.3 μM, ARTD10/PARP10:71.3 μM
In vitro	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. [1]
Kinase Assay	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.
Cell Research	Compound cytotoxicity in A549 and MRC5 cells is evaluated using WST-1 assays. A549 cells are cultured in Dulbecco’s Modified Eagle’s Medium supplemented with 10% fetal calf serum (FCS), penicillin, and streptomycin. MRC5 cells are cultured in Minimal Essential Medium supplemented with 10% FCS, penicillin, streptomycin, and l-glutamine. Both cell lines are maintained in a humidified incubator at 37°C and 5% CO2.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
