ΔFOSB/JUND 13.7 |
ΔFOSB 12.3 μM (IC50) |
YL0441 (0-200 μM; 15 min) disrupts the binding of purified full-length mouse ΔFOSB/JUND heterodimers and ΔFOSB/ΔFOSB homomers to a TAMRA-labeled AP-1 consensus oligonucleotide with IC50 values of 13.7 μM and 12.3 μM, respectively[1].
YL0441 (12.5-50 μM; 72 h) shows no detectable toxicity to Neuro 2A cells at concentrations up to 50 μM after 72 h of incubation[1].
YL0441 (1 μM; up to 60 min) exhibits high metabolic stability in mouse liver microsomes, with a half-life greater than 186.38 min[1].

Administration:infused into the
hippocampus; continuous; 3 consecutive days -
Result:Reduced total ΔFOSB-bound genomic DNA peaks from 9642 to 540, representing a ~94% reduction in total binding events.
Decreased average peak width of remaining ΔFOSB-bound sites from ~286 bp to ~254 bp.
Reduced ΔFOSB binding to unique target genes by ~94%, with a 95% reduction in promoter-bound genes and 91% reduction in distal intergenic-bound genes.
Eliminated ΔFOSB occupancy across all genomic regions (promoters, exons, introns, distal intergenic regions), with no induction of ΔFOSB binding to novel ectopic sites.

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 (6.49 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (6.49 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
