Bar graph showing the effect of the PBEF inhibitor FK866 on PLB-induced autophagy in PC-3 cells. Data are presented as the mean ± SD of three independent experiments. *P<0.05; **P<0.01; and ***P<0.001 by one-way ANOVA.

Paraffin-embedded tumor sections derived from MiaPaCa-2 were stained with H&E or anti-Ki67 antibodies (Scale bar: 100 μm); apoptotic cells were visualized by TUNEL staining (green) and counterstained with DAPI (blue) (Scale bar: 10 μm). The proliferation index and apoptotic index in tumor sections were also quantified. These animal experiments were repeated once (n = 5mice per treatment group).

Inhibition of NAMPT enzymatic activity decreases osteoclast recruitment in the bone remodeling model. FK866‐loaded osmotic pumps were implanted 48 hr before maxillary‐molar extraction. Rats were sacrificed 4 days after tooth extraction. Osteoclast recruitment and activity were analyzed by TRAP enzymatic staining (a) and quantified (b, c and d). N.Oc/BPm: number of TRAP+ osteoclasts per mm of bone surface, Oc.S:BS (%): resorption surface, N.Nc: mean number of nuclei per osteoclast. Magnification ×200. Boxes are delimited by the first and third quartiles (Q1, Q3) and the line shows the median. Outliers are represented by the extreme values, defined as values lower then Q1—1.5 IQR (Inter Quartile Range) or higher then Q3 + 1.5 IQR. (+) represents the mean, *p ≤ 0.05, **p ≤ 0.01 by the Mann-Whitney U-test.

APO866 at low concentrations ranging from 0.09-27 nM induces dose-dependent cytotoxicity in 41 hematologic malignant cells including acute myeloid leukemia [AML], acute lymphoblastic leukemia [ALL], mantle cell lymphoma [MCL], chronic lymphocytic leukemia [CLL], and T-cell lymphoma. APO866 at low concentrations ranging from 0-10 nM induces cell death, this effect is independent of caspase activation but is associated with depolarization of mitochondrial membrane. APO866 at concentrations ranging from 0-10 nM dose-dependently induces depletion of intracellular NAD and ATP contents and cell death in various hematologic cancer cells.  APO866 at concentration of 10 nM inhibits PBEF-induced secretion of MMP-3, CCL2, and CXCL8 in HFFF2 cells. 
|In vivo||APO866 administered intraperitoneally at dose of 20 mg/kg twice a day for 4 days, repeat weekly over 3 weeks, prevents and abrogats tumor growth in C.B.-17 SCID mice xenograft models of human AML, lymphoblastic lymphoma, and leukemia.  APO866 at dose of 0.12 mg/kg/hour prevents joint destruction and leukocyte infiltration through inhibition of PBEF in mice with CIA. |

|In vitro||Ethanol||78 mg/mL (199.22 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+40% PEG 300+5% Tween 80+50% ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions
We are considering the use of S2799 for in vivo injections, Any suggestions for the formula?
The vehicle we recommend for S2799 in vivo study is 45% Propylene glycol (dissolve first) +5% Tween 80+ddH2O. You can dissolve the compound in Propylene glycol first and then dilute with water with Tween 80. The solution is clear and can be used for injection.
