In a concentration-dependent manner, DDO-7263 (20 μM; 2-24 h) can increase the levels of HO-1 and NQO1 proteins [1]. At 400 μM H2O2, PC12 and THP-Ms cells can be upregulated by DDO-7263 (2.5, 5, 10, 20, 40, 80 μM; 24 h) in a concentration-dependent way. Cell viability is not substantially decreased by DDO-7263 alone [1].

| ln Vivo |
DDO-7263 (10-100 mg/kg/day; i.p.; for 10 days) dramatically reduces chemically induced dopaminergic neuron tyrosine hydroxylase in the substantia nigra (SN) (TH) loss and mouse brain striatum, as well as inhibits the secretion of inflammatory factors. It also improves MPTP-induced behavioral abnormalities in mice [1]. In rats, DDO-7263 (7, 35, 70 mg/kg; IP) had a Cmax of 1.38 mg/mL and a T1/2 of 3.32 hours [1].

| Cell Assay |
Western Blot Analysis[1]
Cell Types: PC12 cells Tested Concentrations: 20 μM Incubation Duration: 2, 4, 8, 12, 24 hrs (hours) Experimental Results: Upregulated the protein levels of HO-1 and NQO1 in concentration-dependent manners. |
| Animal Protocol |
Animal/Disease Models: Male C57BL/6 mice at 10 weeks of age and body weights of 22-26 g[1]
Doses: 10, 50, 100 mg/kg Route of Administration: IP; daily for 10 days Experimental Results: Improved the reduction of vertical spontaneous activity and mitigated the loss of balance coordination caused by MPTP (20 mg/kg/day; 7 days). Protected dopaminergic neurons from MPTP. Dramatically downregulated the levels of pro-inflammatory factors, including IL-1β and TNF-α, in mouse plasma. Animal/Disease Models: SD rats[1] Doses: 7, 35, 70 mg/kg (pharmacokinetic/PK Analysis) Route of Administration: IP Experimental Results: Had a T1/2 of 3.32 hrs (hours) and a Cmax of 1.38 mg/mL. |

| Solubility (In Vivo) |
Solubility in Formulation 1: 1.79 mg/mL (6.55 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 17.9 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

| 5 mM | 0.7320 mL | 3.6598 mL | 7.3196 mL | |
| 10 mM | 0.3660 mL | 1.8299 mL | 3.6598 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.
