DB1976 dihydrochloride is a selenophene analog of DB270 and a potent and cell-permeable fully efficacious transcription factor PU.1 inhibitor. DB1976 dihydrochloride potently inhibits PU.1 binding (IC₅₀ of 10 nM) and strongly inhibits the PU.1/DNA complex (with high DB1976-λB affinity, K_D of 12 nM) in vitro. DB1976 dihydrochloride has apoptosis-inducing effect.

Description

IC₅₀ & Target

IC50: 10 nM (Transcription factor PU.1)^[1]

In Vitro

DB1976 is a classic heterocyclic dication (a single heteroatom) with strong affinity and selectivity for AT-rich sequences commonly found in cognate DNA binding sites for PU.1^[2].
DB1976 inhibits PU.1-dependent transactivation of the reporter in a dose-dependent manner with an IC₅₀ value of 2.4 μM in PU.1-negative HEK293 cells^[3].
DB1976 treatment leads to a profound decrease in the growth of PU.1 URE^–/– AML cells (IC₅₀ of 105 μM), while showing little effect on normal hematopoietic cells at similar concentrations (IC₅₀ of 334 μM)^[3].
DB1976 treatment leads to a 1.6-fold increase in apoptotic cells in murine PU.1 URE^–/– AML cells, and observed similar effects in human MOLM13 cells^[3].
DB1976 treatment leads to a significant decrease in the number of viable cells (primary human AML cells) (mean decrease of 81%) and clonogenic capacity (mean decrease of 36%) compared with vehicle-treated cells. The apoptotic cell fraction increased on average by 1.5-fold with DB1976^[3].

* 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, 1 year; -20°C, 6 months (sealed storage, away from moisture). When stored at -80°C, please use it within 1 year. When stored at -20°C, please use it within 6 months.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

Concentration _(start) × Volume _(start) = Concentration _(final) × Volume _(final)

This equation is commonly abbreviated as: C₁V₁ = C₂V₂

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 (4.81 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL.
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.
