Padnarsertib attenuates the PAK4/β-catenin pathway, results in NAD depletion, and attenuates viability, invasion, and migration in several RCC cell lines. Inhibition of NAMPT in a cell-free enzymatic assay using recombinant NAMPT shows an IC50 of approximately 120 nM for Padnarsertib. Padnarsertib attenuates G2–M transit and induces apoptosis in RCC cell lines[2].

Padnarsertib is currently being investigated in a phase I human clinical trial of patients with advanced solid malignancies and NHL[2].
Padnarsertib (oral administation; 100mg/kg or 200 mg/kg; twice a day; 14 days) demonstrates a decrement of xenograft growth without no significant weight loss. 8 hours after, Padnarsertib are measured at the end of the experiment in mouse plasma and tumors with 10757 ng/mL and 10647 ng/mL, respectively[3].

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: 2.08 mg/mL (3.41 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.08 mg/mL (3.41 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
