Description

PDD 00017273 is a potent inhibitor of Poly(ADP-ribose) Glycohydrolase (PARG), with an IC50 of 26 nM, and a KD of 1.45 nM[1][2].

IC50 & Target

IC50: 26 nM (PARG)[1]
KD: 1.45 nM (PARG)[1]
In Vitro

PDD 00017273 is a potent inhibitor of PARG, with an IC50 of 26 nM, and a KD of 1.45 nM. PDD 00017273 (10 μM) does not inhibit five common Cytochrome P450 enzymes. PDD 00017273 (30 μM) modestly increasess phosphorylated H2AX (γH2AX) intensity, PDD 00017273 also decreases in NAD/H through PARG inhibition after DNA damage. PDD 00017273 suppresses the ZR-75-1 cells carring BRCA1 and BRCA2 wild type, and exhibits less potent activities against MDA-MB-436 cells carry the 5396 + 1G>A mutation in BRCA1[1]. PDD 00017273 (0.3 μM) inhibits degradation of PAR polymers in MCF7 cells. PDD 00017273 (0.3 μM) also reduces the viability of BRCA1, BRCA2, PALB2, FAM175A, and BARD1 depleted cells. PDD 00017273 stalls replication forks and induces DNA damage that requires homologous recombination (HR) for repair[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (4.86 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (4.86 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Briefly, PARG in vitro assays are conducted in a total volume of 15 μL in a standard 384-well format. A total of 5 μL of human full length PARG used at a final reaction concentration of 65 pM, is added to 5 μL of Bt-NAD ribosylated PARP1 substrate at a final reaction concentration of 4.8 nM in assay buffer (50 mM Tris pH 7.4, 0.1 mg/mL BSA, 3 mM EDTA, 0.4 mM EGTA, 1 mM DTT, 0.01% Tween 20, 50 mM KCl). The reaction is incubated at RT for 10 min, and then 5 μL of detection reagent is added. Detection reagent consists of 42 nM mAb anti-6HIS XL665 and 2.25 nM streptavidin europium cryptate, both at 3× working stock concentrations (final concentrations of 14 nM and 0.75 nM, respectively), in detection buffer (50 mM Tris pH 7.4, 0.1 mg/mL BSA and 100 mM KF). Following incubation at RT for 60 min in the dark, TR-FRET signal is measured at λEx 340 nm and λEm 665 nm and λEm 620 nm using a PHERAstar FS plate reader. The ratio is calculated as [Em665/EM620] × 104 for each well and used to calculate percent inhibition for test compounds[1].

Cell Assay
[1]

HeLa cells are seeded in 30 μL of media at 1 × 104 cells/mL in Greiner 384-well plates. A total of 16-24 h later, cells are treated with inhibitors (8 pt dose response, 0.01-30 μM, triplicates) or vehicle (DMSO) control. The outer wells are left undosed to account for edge effects. After 72 h, 50 μL of 3.7% formaldehyde/PBS is added to each well, and cells are fixed for 20 min. Cells are then rinsed twice with PBS and stained for 1 h with Hoechst 33342/PBS (1:2000) in the dark. After two further rinses with PBS, images are captured and nuclei counted on a CellInsight. The maximum number of fields are captured from each triplicate well, which approximated to at least 1000 nuclei in vehicle-dosed wells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
