Biological Activity
IC50: 0.57 nM (PARP1)[1]
Talazoparib is a potent PARP1/2 inhibitor (PARP1 IC50=0.57 nM), it has no effect on PARG activity at concentrations up to 1 μM. Talazoparib binds to PARP1 with a dissociation constant (KD) of 0.29 nM. Talazoparib inhibits PARP1 and -2 to a similar extent, with Kis of 1.20 and 0.85 nM, respectively. Talazoparib selectively targets tumor cells with BRCA1, BRCA2, or PTEN gene defects with 20- to more than 200-fold greater potency than existing PARP1/2 inhibitors. Talazoparib targets tumor cells with homologous recombination gene defects. Tumor models that are either BRCA1-deficient (MX-1 and SUM149) or BRCA2-deficient (Capan-1) are profoundly sensitive to Talazoparib. Talazoparib induces nuclear γ-H2AX foci at concentrations as low as 100 pM[1].

Solvent & Solubility
DMSO : ≥ 108 mg/mL (195.46 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.52 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.

4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
LoVo cells are treated with Talazoparib (10, 40 nM) and temozolomide (TMZ) either alone or in combination for 5 days. Surviving fraction is determined using CellTiter-Glo assay.[1]
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
In single-agent studies, olaparib (100 mg/kg), Talazoparib (0.33 or 0.1 mg/kg/d), or vehicle (10% DMAc, 6% Solutol, and 84% PBS) is administered by oral gavage (per os), once daily or Talazoparib (0.165 mg/kg) twice daily for 28 consecutive days. Mice are continuously monitored for 10 more days after last day of dosing[1].
