Actividad biológica
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].

Solvente y solubilidad
DMSO : 50 mg/mL (155.59 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (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.
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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
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.
Protocolo
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.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
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.
