HJM-561
Based on 1 Customer Validation
HJM-561 is a selective and effective orally active EGFR PROTAC degrader. HJM-561 is able to overcome the triple EGFR mutations that are resistant to Osimertinib (HY-15772). HJM-561 exhibits potent degradation of EGFR Del19/T790M/C797S (DC50: 9.2 nM) and L858R/T790M/C797S (DC50: 5.8 nM), and has anti-tumor activity (pink: EGFR ligand (HY-12857); blue: CRBN ligand (HY-A0003); black: linker).

Biological Activity
HJM-561 (0-300 nM, 24 h) potently degrades EGFR Del19/T790M/C797S (DC50: 9.2 nM) and L858R/T790M/C797S (DC50: 5.8 nM), but has no effect on wild-type EGFR[1].
HJM-561 (100 nM, 24 h) degrades the EGFR triple mutant in Del19/T790M/C797S Ba/F3 cells by activating CRBN E3 ligase and ubiquitin-proteasome system[1].
EGFR mutant, with IC50 of 15.6 and 17.0 nM in Del19/T790M/C797S cells and L858R/T790M/C797S cells, respectively[1].
EGFR expression (HEK293T and MDA-MB-231), indicating that it has no effect on cells expressing wild-type EGFR[1].

Solvent & Solubility
DMSO : 100 mg/mL (115.69 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, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 2.5 mg/mL (2.89 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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
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.
