Product Description

Daporinad (APO866; FK-866; APO-866; K 22.175) is a novel and potent inhibitor of nicotinamide phosphoribosyltransferase (NMPRTase) with potential antitumor and antiangiogenic activity. It inhibits NMPRTase with an IC50 of 0.09 nM in a cell-free assay. FK866 acts by binding to and inhibiting nicotinamide phosphoribosyltransferase (NMPRTase), thus blocking the biosynthesis of nicotinamide adenine dinucleotide (NAD+) from niacinamide (vitamin B3), which may deplete energy reserves in metabolically active tumor cells and induce tumor cell apoptosis. In addition, Daporinad may inhibit the production of vascular endothelial growth factor (VEGF) in tumor cells, leading to the inhibition of tumor angiogenesis.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
By selectively killing MM cells, Nampt inhibition with (E)-Daporinad (FK866) causes a large intracellular decrease in NAD+. Higher baseline NAD+ levels in MM cells than in normal PBMCs give (E)-Daporinad (FK866) sensitivity. (E)-Daporinad (FK866)-induced cell death is related with inhibition of Nampt activity, rather than protein expression. The bone marrow microenvironment's survival advantage is eliminated by (E)-Daporinad (FK866)[1]. (E)-Daporinad (FK866) lowers the Ca2+ content of TG-responsive Ca2+ stores in Jurkat and activated PBLs and inhibits the [Ca2+]i rise brought on by various mitogens. The Ca2+ content of TG-responsive Ca2+ stores in Jurkat cells is decreased by (E)-Daporinad (FK866), but not in Bcl2-Jurkat cells[2]. Using the p53 acetylation route, suppression of NAMPT by (E)-Daporinad (FK866) or inhibition of SIRT by nicotinamide reduces proliferation and causes death of 293T cells[3].
ln Vivo
In CB17-SCID mice, (E)-Daporinad (FK866) (30 mg/kg, ip) reduces the tumor burden and significantly reduces ERK phosphorylation and proteolytic cleavage of LC3 in the tumor tissue[1].
Animal Protocol
Dissolved in 0.9% saline; 20 mg/kg; i.p. injection
C.B.-17 SCID mice xenograft models of human AML, lymphoblastic lymphoma, and leukemia.

*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
