In an isogenic model of BRCA1 deficiency that has been previously described, ART558 (0~10 μM; 7 days) demonstrated synthetic lethality when combined with PARPi olaparib [1]. γH2AX accumulates in cells treated with ART558 (5μM; 0~72 hours; BRCA2 wild-type or BRCA2-/- cells) [1]. Without affecting nonhomologous end joining, ART558 suppresses the primary Polβ-mediated DNA repair mechanism, Theta-mediated end joining. In tumor cells with BRCA1 or BRCA2 mutations, ART558 causes damage to DNA, promotes synthetic lethality, and amplifies the effects of PARP inhibitors. In 53BP1-deficient cells, ART558 raises biomarkers and synthetic lethality of single-stranded DNA; however, these effects are reversed when DNA nucleases that induce end resection are inhibited, indicating that these effects are connected to the process of synthetic lethality. YFP-labeled full-length Polθ has a longer residency duration at the site of laser-induced DNA damage when treated with ART558 [1].

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 5 mg/mL (11.95 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 2: 4.25 mg/mL (10.16 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 42.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.2390 mL | 1.1950 mL | 2.3900 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
