In Vitro

Dacomitinib (PF00299804) effectively inhibits the in vitro kinase activity of wild-type EGFR (IC50=6 nM)with similar efficacy. Dacomitinib also effectively inhibits wild-type ERBB2 with IC₅₀ of 45.7 nM. In H441, an IC₅₀ is reached with Dacomitinib but only at a very high concentration (4 μM) and likely reflects off-target effects. In cell lines wild-type for both EGFR and K-ras (H322, H1819, and Calu-3), ZD1839 and Dacomitinib both effectively inhibit growth of H1819 and Calu-3 cells but not of H322 cells. Dacomitinib is a pan-ERBB inhibitor and most EGFR mutant cell lines express multiple ERBB family members, the effects on EGFR phosphorylation could potentially be indirect. Dacomitinib inhibits EGFR phosphorylation in all of the different EGFR T790M proteins whereas ZD1839 is ineffective even at 10 μM. In the NIH3T3 cells, phosphorylation of EGFR L858R/T790M is completely inhibited by 1 nM Dacomitinib, whereas 100 nM or greater is required to inhibit EGFR WT/T790M or Del/T790M^[1]. The HER2-amplified cell lines are most sensitive to growth inhibition by Dacomitinib (IC₅₀<1 μM in 14 of 16 lines; 87.5%) as compared with 5 of 28 (17.9%) of HER2-nonamplified lines (excluding immortalized lines)^[2].

In Vivo

To evaluate the efficacy of Dacomitinib, xenografts in nu/nu mice are generated using HCC827 GFP and HCC827 Del/T790M cells and treated the mice with Dacomitinib. Dacomitinib (10 mg/kg/d by daily oral gavage) effectively inhibits the growth of HCC827 GFP xenografts. In contrast, HCC827 Del/T790M xenografts are resistant to ZD1839, whereas Dacomitinib treatment is substantially more effective at inhibiting growth of this xenograft model^[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: ≥ 2.5 mg/mL (5.32 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (5.32 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 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 (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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (5.32 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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 1

Add each solvent one by one: 0.5% CMC/saline water
Solubility: 5 mg/mL (10.64 mM); Suspended solution; Need ultrasonic

Working solution concentration: mg/mL

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.

Cell Assay ^[2]	Cells are seeded in duplicate at 5×10³ to 5×10⁴ cells per well in 24-well plates, and growth inhibition data is calculated. Briefly, day after plating, Dacomitinib is added at 10 μM and 2-fold dilutions over 12 concentrations are carried out to generate a dose-response curve. Control wells without the drug are also seeded. The cells are counted on day 1 when the drug is added, as well as after 6 days when the experiment ended. After the trypsinization cells are placed in an Isotone solution and immediately counted using a Coulter Z1 particle counter. The suspension cultures are counted using a Coulter Vi-Cell counter^[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration ^[1]	Mice^[1] Nude mice (nu/nu; 6-8 weeks old) are used for in vivo studies. A suspension of 5×10⁶ HCC827-GFP or HCC827-Del/T790M lung cancer cells (in 0.2 mL of PBS) are inoculated s.c. into the lower-right quadrant of the flank of each mouse. Five mice are inoculated with either HCC827-GFP or HCC827-Del/T790M cells in the ZD1839 treatment group. Tumors are measured twice weekly using calipers, and volume is calculated using the following formula: length×width²×0.52. Mice are monitored daily for body weight and general condition. Mice are randomized to treatment when the mean tumor volume is 400 to 500 mm³. ZD1839 is administered at 150 mg/kg/d by daily oral gavage. Dacomitinib is administered at 10 mg/kg/d by daily oral gavage. The experiment is terminated when the mean size of the control tumors reached 2000 mm³. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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.
