Description

PF-1355 is a selective 2-thiouracil mechanism-based MPO inhibitor, used for treatment of vasculitic diseases.

In Vitro

In a dose-responsive fashion, PF-1355 inhibits MPO activity in phorbol ester-stimulated human neutrophils as measured by taurine chlorination (EC50=1.47 μM) as well as lipopolysaccharide-treated human blood measuring residual MPO activity (EC50=2.03 μM)[1].

In Vivo

Oral administration of PF-1355 reduces plasma MPO activity, vascular edema, neutrophil recruitment, and elevates circulating cytokines. In a model of anti-glomerular basement membrane disease, formerly known as Goodpasture disease, albuminuria and chronic renal dysfunction are completely suppressed by PF-1355 treatment[1].

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: ≥ 2.08 mg/mL (6.47 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    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.
  • Protocol 2

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

    Solubility: ≥ 2.08 mg/mL (6.47 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Kinase Assay
[1]

Plates are coated with the MPO capture antibody (1:200) overnight at 4°C, washed with PBS, and then nonspecific binding blocked with PBS/1% BSA. Plasma or peritoneal exudate samples are diluted 1:4 in PBS and 50 μL is added to triplicate wells for 1 hour at room temperature. Plates are washed three times with PBS containing 0.05% Tween, followed by PBS ishes. Assay buffer (50 μL containing 50 nM phosphate buffer, pH 7.4, containing 140 mM NaCl, 10 mM Na2NO2, 40 μM Amplex Red, and 10 μM H2O2) is added with kinetic reads and an excitation/emission wavelength of 530/580 nm on a fluorescence plate reader. Assay linearity is typically maintained for >300 seconds (R2 > 0.99) and Vmax represented by the change in relative fluorescence units divided by time to yield MPO activity. Active MPO is back-calculated using purified human MPO standard.

Animal Administration
[1]

Animals receive an intraperitoneal injection of 4% thioglycollate broth in phosphate-buffered saline (PBS) for neutrophil recruitmen. Twenty hours later, PF-1355 or vehicle (1% hydroxypropyl methylcellulose, 0.5% 2-amino-2-hydroxymethyl-propane-1,3-diol, 0.5% hypromellose acetate succinate, pH 9.5) is administered p.o., followed by intraperitoneal administration of opsonized zymosan or saline. After 3 hours, the mice are euthanized and receive intraperitoneal injection of 2 mL cold PBS. Blood is collected and animals are shaken vigorously before the collection of peritoneal lavage.

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.
