PD158780 inhibits EGF receptor autophosphorylation in A431 human epidermoid carcinoma with IC50 value of 13 nM. PD158780 is highly specific for the EGF receptor in Swiss 3T3 fibroblasts, inhibiting EGF-dependent receptor autophosphorylation and thymidine incorporation at low nanomolar concentrations while requiring micromolar levels for platelet-derived growth factor- and basic fibroblast growth factordependent processes. PD158780 inhibits heregulin-stimulated phosphorylation in the SK-BR-3 and MDAMB-453 breast carcinomas with IC50 values of 49 and 52 nM, respectively, suggesting that the compound is active against other members of the EGF receptor family[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: 1.67 mg/mL (5.06 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 1.67 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: 1.67 mg/mL (5.06 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 1.67 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 (16.7 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocolo
The enzyme assay is performed in 96-well filter plates. The total volume is 0.1 mL containing 20 mM HEPES, pH 7.4, 50 μM sodium vanadate, 40 mM magnesium chloride, 10 μM ATP containing 0.5 μCi of [32p]ATP, 20 μg of polyglutamic acid/tyrosine, 1 ng of EGF receptor tyrosine kinase, ard appropriate dilutions of inhibitor (PD158780) and/or ATP. All corrtponents except the ATP are added to the well, and the plate is incubated with shaking for 10 min at 25°C. The reaction is started by adding [32p]ATP, and the plate is incubated with shaking at 25°C for 10 min. The reaction is terminated by the addition of 0.1 mL of 20% TCA, and the plate is kept at 4°C for at least 15 min to allow the substrate to precipitate. The wells are then ished five times with 0.125 mL of 10% TCA, and [32p] incorporation is determined[1].

All cell lines are maintained as monolayers in dMEM/F12, 50:50 containing 10% fetal bovine serum. For growth inhibition assays, dilutions of the designated compound (PD158780) in 10 μL are placed in 24-well plates followed by the addition of cells in 2 mL of medium. The plates are incubated for 72 hr at 37°C in a humidified atmosphere. Cell growth is determined by counting cells[1].
