In Vitro

PNU-177864 (1-10 μM, 30 min) reduces CCR5 expression in THP1, reduces inflammation^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .

In Vivo

PNU-177864 (0-200 mg/kg,p.o., once daily for 2 weeks) can cause significant phospholipidosis and associated myopathy under certain conditions in rats, with plasma levels increasing throughout 24 hours at high doses. It remains high and almost unchanged over the dosing interval, but it has no obvious toxicity at lower doses^[2].
PNU-177864 (0-200 mg/kg, p.o., once daily for 2 weeks) in rats and dogs is the accumulation of phospholipids in epididymal epithelial cells^[3].

Result:

Showed lymphoid tissue (lymph nodes, foamy macrophages in the white medulla of the spleen or Peyer's patches), alveolar macrophages, epididymal epithelial cells, peripheral blood lymphocytes, lymphocytes and plasma cells all show changes consistent with phospholipidosis.
Showed morphological changes in the affected tissues show obvious, clear vacuoles or foamy appearance in the cytoplasm of plasma cells, lymphocytes or epithelial cells and macrophages. After the recovery period, no histological and electron microscopic signs of phospholipidosis were found except in the epididymis.
Showed multifocal to extensive myocyte degeneration in skeletal muscle, with accumulation of phospholipids observed under light microscopy.

Animal Model:

9–10-month-old beagle dogs^[3]
Dosage:

0, 2, 10, 50 mg/kg/day, 2 weeks; 0, 0.5, 4, 32 mg/kg/day, 4 weeks
Administration:

Oral
Result:

Showed lymphoid tissue (lymph nodes, foamy macrophages in the white medulla of the spleen or Peyer's patches), alveolar macrophages, epididymal epithelial cells, and peripheral blood lymphocytes showed changes consistent with phospholipidosis. After the recovery period, no histological and electron microscopic signs of phospholipidosis were found except in the epididymis.
Showed no histological changes were found in the epididymal epithelial cells; sperm density and morphology were normal histologically; the dogs had normal sperm concentration, morphology, and motility.

Stock Solution Working Solution

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: ≥ 5 mg/mL (12.42 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.

Protocol 2

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

Solubility: ≥ 5 mg/mL (12.42 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
