ML 2-14
Based on 1 publication(s) in Google Scholar
ML 2-14 is a PROTAC targeting BRD4 with a C4 alkyl linker. ML 2-14 consists of the E3 ligase ligand EN219 (HY-115715) (bule part), the target protein ligand JQ-1 (HY-13030) (red part), and the PROTAC linker (balck part). ML 2-14 can effectively degrade BRD4 in 231MFP breast cancer cells, and this effect can be reversed by the proteasome inhibitor Bortezomib (HY-10227) and the E1 activase inhibitor TAK-243 (HY-100487). ML 2-14 can be used for breast cancer-related research.

BRD4 |
ML 2-14 (1 nM-1 μM; 8 h) significantly degraded BRD4 in 231MFP breast cancer cells, with DC50 values of 36 and 14 nMfor the long and short isoforms of BRD4, respectively[1].
The degradation of BRD4 by ML 2-14 (100 nM; 8 h) in 231MFP cells could be blocked by Bortezomib (4 μM; 30 min prior) and the E1 activating enzyme inhibitor TAK-243 (10 μM; 8 h prior)[1].

Solvent & Solubility
DMSO : 100 mg/mL (117.97 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 (2.95 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.
