eCF506
Based on 7 publication(s) in Google Scholar
eCF506 (NXP900) is a highly potent and orally active YES1/SRC kinase inhibitor with an IC50 of 0.47 nM. eCF506 locks its target into its native “closed” conformation, thereby inhibiting both kinase activity and complex formation with protein partners. eCF506 can be used for the study of esophageal squamous cancer and breast cancer.

[PMID: 27115835] |
eCF506 induces a very potent antiproliferative effect in both MCF7 and MDA-MB-231 cells. eCF506 inhibits phosphorylation of SRC and FAK at low nanomolar levels, with complete inhibition observed at 100 nM. eCF506 significantly reduces cell motility at 10 nM as early as 6 h into the study, with equivalent efficacy to dasatinib. eCF506 exclusively inhibits SFK, with subnanomolar IC50 values against SRC and YES (IC50=0.5, 2.1 nM). It is important to highlight that eCF506 displays a vast difference in activity (>950-fold difference) between ABL and its primary target SRC[1].

Solvent & Solubility
DMSO : 62.5 mg/mL (122.40 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
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 (4.07 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 (4.07 mM); Clear solution

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.
Protocol
MDA-MB-231 cells are treated with eCF506 or dasatinib (10 nM), and cell migration compared with untreated cell control (DMSO, 0.1%, v/v) at 6, 12, and 24 h. Cells are imaged and analyzed using an IncuCyte-ZOOM microscope with integrated scratch-wound migration software module[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
In vivo PD study is performed in a xenograft model of HCT116 cells in mice. HCT116 cells are injected subcutaneously, and tumors are allowed to grow up to 3-mm in diameter. Subsequently, mice are dosed daily for 3 d with eCF506 (50 mg/kg, in nanopure water) or vehicle (nanopure water) by oral gavage and culled 3 h after the last dose (n=4). Tumors are excised, fixed, and sections labeled for phospho-SRCY416 and stained with hematoxylin[1].
