A1874 is an orally active BRD4 PROTAC degrader with a DC₅₀ of 32 nM. A1874 degrades BRD4 via the ubiquitin-proteasome system by recruiting the MDM2 E3 ligase, while disrupting the MDM2-p53 interaction to stabilize p53 and upregulate p21, thereby inducing cell cycle arrest and apoptosis. A1874 exhibits selectivity for wild-type p53 cells and MDM2-amplified tumors, and it can be used in research on breast cancer, colorectal cancer, melanoma, lung cancer, lymphoma, myeloid leukemia, osteosarcoma, and glioblastoma.

A1874 (500 nM; 18 h) induces BRD4 degradation and upregulates the protein levels of MDM2 and p53 in HCT116 cells after 18 h of treatment; when combined with Doxorubicin (HY-15142A), Camptothecin (HY-16560) or Mitomycin C (HY-13316), it dose-dependently inhibits A1874-induced BRD4 degradation by downregulating MDM2 expression, whereas combination with Etoposide (HY-13629) does not interfere with the activity of A1874^[3].

A1874 induces significant degradation of nuclear BRD4 protein in U-87 MG cells and temozolomide-resistant U-87 MG TR cells, while it increases the expression levels of c-Myc and MDM2 proteins and elevates the content of nuclear TP53 in U-87 MG cells^[4].
A1874 upregulates BRD4 mRNA expression and downregulates p53 mRNA expression in U-87 MG cells, but exerts no significant effect on the mRNA expression of BRD4, c-Myc or p53 in Temozolomide-resistant U-87 MG TR cells^[4].

Stock Solution Working Solution

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 (2.13 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (2.13 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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
