Product Description
SCR7 pyrazine is a DNA ligase IV (DNA ligase IV) inhibitor that blocks nonhomologous end joining (NHEJ) in a ligase IV-dependent manner. SCR7 pyrazine is also a CRISPR/Cas9 enhancer that can improve the efficiency of Cas9-mediated homology-directed repair (HDR). SCR7 pyrazine causes apoptosis and has anti-cancer effect.
Biological Activity I Assay Protocols (From Reference)
Targets
DNA Ligase IV; CRISPR/Cas9
ln Vitro
SCR7 pyrazine (20-100 μM; 24 hours; MCF7 cells) treatment causes unrepaired double-strand breaks (DSBs) to accumulate in cells by interfering with NHEJ[1].
SCR7 pyrazine treatment results in a dose-dependent reduction in cell proliferation, with IC50 values for MCF7, A549, HeLa, T47D, A2780, HT1080, and Nalm6 cells, respectively, of 40 μM, 34 μM, 44 μM, 8.5 μM, 120 μM, 10 μM, and 50 μM[1].
SCR7 pyrazine (20, 40 μM) treatment of MCF7 cells results in increased phosphorylation of ATM and activates p53, while decreasing MDM2, BCL2, and activating proapoptotic proteins, PUMA and BAX. Furthermore, there is a dose-dependent increase in the cleavage of the shorter fragments of MCL1, PARP1, Caspase 3, and Caspase 9[1].
ln Vivo
SCR7 pyrazine (10 mg/kg; intraperitoneal injection; six doses; BALB/c mice) treatment lengthens life expectancy and significantly reduces tumors caused by breast adenocarcinoma[1].

10 mg/kg
Intraperitoneal injection; on alternate days (0, 2, 4, 6, 8, and 10)

Shipping Condition
Room temperature (This product is stable at ambient temperature for a few days during ordinary shipping and time spent in Customs)
Solubility Data
Solubility (In Vitro)
DMSO: ~66 mg/mL (~198.6 mM)
Ethanol: ~23 mg/mL (~69.2 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.52 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 25.0 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.

Solubility in Formulation 2: ≥ 2.5 mg/mL (7.52 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (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 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)

1 mM 3.0086 mL 15.0430 mL 30.0860 mL
5 mM 0.6017 mL 3.0086 mL 6.0172 mL
10 mM 0.3009 mL 1.5043 mL 3.0086 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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
