Biological Activity
IC50: 0.8 μM (LMPTP-A)[1]
LMPTP INHIBITOR 1 (dihydrochloride) is a selective inhibitor of low molecular weight protein tyrosine phosphatase, with an IC50 of 0.8 μM LMPTP-A and shows more potent effect on LMPTP-A versus LMPTP-B. LMPTP inhibitor 1 (Compound 23; 10 μM) also enhances HepG2 IR phosphorylation after insulin stimulation in human HepG2 hepatocytes[1].

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 (4.83 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.83 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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
Phosphatase assays are performed in buffer containing 50 mM Bis-Tris, pH 6.0, 1 mM DTT and 0.01% Triton X-100 at 37°C. For assays conducted with 3-O-methylfluorescein phosphate (OMFP) as substrate, fluorescence is monitored continuously at λex = 485 and λem = 525 nm. For assays conducted with para-nitrophenylphosphate (pNPP) as substrate, the reaction is stopped by addition of 2X reaction volume of 1 M NaOH, and absorbance is measured at 405 nm. IC50 values are determined from plots of LMPTP inhibitor 1 concentration versus percentage of enzyme activity. For inhibitor selectivity assays, each PTP is incubated with either 0.4 mM OMFP or 5 mM pNPP in the presence of 40 μM LMPTP inhibitor 1 or DMSO. Equal units of enzyme activity, comparable to the activity of 10 nM human LMPTP-A, are used. For the inhibitor reversibility assay, 50 nM human LMPTP-A is pre-incubated with 10 μM LMPTP inhibitor 1 or DMSO for 5 min. The enzyme is diluted 100X in phosphatase assay buffer containing 0.4 mM OMFP and fluorescence is measured at the indicated time points[1].

Human HepG2 cells are cultured in Eagle’s Minimal Essential Medium (ATCC) containing 10% fetal bovine serum (FBS), 100 U/mL penicillin and 100 μg/mL streptomycin. The absence of Mycoplasma contamination in HepG2 cultures is confirmed using the Lonza MycoAlert Mycoplasma Detection Kit. Cells are treated with 10 μM LMPTP inhibitor 1 in serum-starvation media (0.1% FBS) overnight, following which cells are stimulated with 10 nM bovine insulin for 5 min at 37°C. For detection of IR tyrosine phosphorylation by immunoprecipitation/Western blotting, cells are lysed in radioimmunoprecipitation assay buffer containing 1 mM phenylmethylsulfonyl fluoride, 10 μg/mL aprotinin/leupeptin, 10 mM sodium orthovanadate, 5 mM sodium fluoride, and 2 mM sodium pyrophosphate, and the IR is immunoprecipitated using the anti-IRβ Ab. IR tyrosine phosphorylation of immunoprecipitates is determined by Western blotting with the anti-pIR/pIGFR-Y1162/Y1163 Ab[1].

Mice[1]
LMPTP inhibitor 1 is administered to male B6 or Acp1fl/fl albumin-Cre+ DIO mice at 0.05% w/w in high-fat diet (HFD) rodent chow. Control groups consist of male B6 or Acp1fl/fl albumin-Cre+ littermate mice administered HFD rodent chow alone. Mice are allowed food and water ad libitum and weighed daily. Randomization is not used in these experiments; rather littermate mice are assigned to treatment or control groups in a manner to maintain similar mean body weights between the 2 groups at the start of the study. Insulin-induced liver IR phosphorylation, IPGTT and fasting insulin levels are assessed after treatment. Diabetic (displaying overnight [13 hr] fasting blood glucose levels ≥140 mg/dL) B6 DIO mice are used in experiments to assess IPGTT and fasting insulin levels[1].
