D-I03
Based on 3 publication(s) in Google Scholar
D-I03 is a selective RAD52 inhibitor with a Kd of 25.8 μM. D-I03 specifically inhibits RAD52-dependent single-strand annealing (SSA) and D-loop formation with IC50s of 5 μM and 8 μM, respectively. D-I03 suppresses growth of BRCA1- and BRCA2-deficient cells and inhibits formation of damage-induced RAD52 foci, but does not effect on RAD51 foci induced by Cisplatin.

Biological Activity
D-I03 (0-10 μM; on days 1 and 3; Capan-1 and UWB1.289 cells) treatment preferentially suppressed the growth of Capan-1 and UWB1.289 cells in a concentration-dependent manner[1].
D-I03 inhibits RAD52 foci formation induced by cisplatin in BCR-ABL1-positive BRCA1-deficient 32Dcl3 murine hematopoietic cell line that expresses GFP-RAD52. In the presence of D-I03 (2.5 μM), the fraction of cells with RAD52 foci is decreased, from 38.7% to 171%; at the same time, the fraction of Cisplatin-treated cells without foci is increased from 48.4% to 71.9%. D-I03 does not effect on RAD51 foci induced by Cisplatin. Also, D-I03 alone induce neither RAD51 foci nor RAD52 foci (in BRCA1-deficient cells) indicating low genotoxicity of D-I03[1].

Cell Line:Capan-1 (BRCA2−) and UWB1.289 (BRCA1+) cells
-
Concentration:0 μM, 2.5 μM, 5 μM, or 10 μM

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 (5.83 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)
