Three described PME-1 inhibitors are tested in this assay and a thermal shift with 100 μM ABL127 is detected. Using 25 or 50 μM ABL127 also shows a shift in protein melting temperature. It is found that treatment of Ishikawa cells with ABL127 and AMZ-30 significantly decreases cell proliferation similarly to depletion of PME-1 with shRNA. It is also found that treatment of ECC-1 cells with ABL127 or AMZ-30 affects cell invasion in a dose-dependent manner. The treatment of EC cells with ABL127 leads to a significant ~45 % increase in protein phosphatase 2A (PP2A) activity, while treatment with AMZ-30 leads to a modest ~10 % increase in PP2A activity[1].

Solvent & Solubility
DMSO : ≥ 100 mg/mL (300.89 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" 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. 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 (7.52 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 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 (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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.52 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 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.

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
Human PME-1 protein lacking the last three amino acids (PME-1des3) is purified from Sf9 cells. The assay is completed by first conducting a 10 min pre-incubation of 1 μM PME-1des3 with 100 μM ABL127, 100 μM AMZ-30, 100 μM EHT, or vehicle (0.05 % DMSO) in the presence of SYBR Orange (1:1000, v/v) at 37°C in 1× NEB buffer 2 (50 mM NaCl, 10 mM Tris-HCl, 10 mM MgCl2, 1 mM DTT, pH 7.9 at 25 °C); a thermal gradient is performed increasing temperature by 2°C per minute increments from 37 to 95°C, and fluorescence (492 to 610 nm) is acquired on a thermal cycler[1].

Cells are subjected to 5 μg/mL puromycin selection for 10 to 14 days and are clonally expanded. Validated clones are incubated with media and compounds (including ABL127) for the indicated times for phenotypic assays[1].

ECC-1 cells are subcutaneously inoculated into the flanks of female SCID mice and are allowed to grow until tumors reached ~400 mm3. A single intratumoral dose of ABL127 diluted in 10% DMSO/PBS is administered. The highest concentration tested is 5 mg/kg of ABL127 due to poor solubility of the compound[1].
