Biological Activity
|
PARP-1 0.20 μM (IC50) |
PARP-2 0.24 μM (IC50) |
DR2313 (0.016-16.4 μM; 30 min) inhibits poly(ADP-ribosyl)ation reaction in nuclear extracts of rat brain, with a Ki of 0.23 μM[1].
DR2313 shows more powerful inhibition of the poly(ADP-ribosyl)ation in the nuclear extracts of the rat brain (IC50=0.20 μM) than 3AB (35.4 μM), PND (0.56 μM), DIQ (2.96 μM), and DPQ (0.96 μM)[1].
DR2313 (1-100 μM; 10 min) shows a weak inhibition of the mono(ADP-ribosyl)ation in a concentration-dependent manner (IC50=59 μM)[1].
DR2313 (0.1-30 μM; pretreated for 30 min) reduces hydrogen peroxide (500 μM; 4 h) or glutamate (1 mM; 30 min) induced excessive formation of poly(ADP-ribose) and cell death[1].

Solvent & Solubility
H2O : ≥ 100 mg/mL (548.70 mM)
DMSO : 12.5 mg/mL (68.59 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* 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.
