Biological Activity

Description

Targets

NMPRTase ^[5]
(Cell-free assay)

0.4 nM(Ki)

In vitro
In vitro	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. ^[1] APO866 at concentration of 10 nM inhibits PBEF-induced secretion of MMP-3, CCL2, and CXCL8 in HFFF2 cells. ^[2]
Cell Research	Cell lines	41 hematologic malignant cell lines
	Concentrations	0 - 10 nM
	Incubation Time	72 hours or 96 hours
	Method	For MTT assays, 0.5 × 10⁶ cells/mL is plated in triplicate on 96-well plates. APO866 (0.01 nM-100 nM) is added in 50 μL of culture medium, with culture medium alone serving as control. After 72 or 96 hours of incubation, 15 μL of dye solution is added to each well and cells are incubated for an additional 4 hours. Stop solution (100 μL/well) is added for 1 hour and the absorbance is read at 570 nm on a spectrophotometer. For trypan blue dye exclusion staining, 0.5 × 10⁵ cells/well is grown in 6-well plates with 1 mL media in the absence or presence of APO866 for 96 hours. Cells from each sample are incubated with 10 μL trypan blue solution (at a 1:1 ratio [vol/vol] for 1 minute). Cell survival is determined by calculating proportion of live (unstained) cells.

Frequently Asked Questions

Question 1:
We are considering the use of S2799 for in vivo injections, Any suggestions for the formula?

Answer:
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.
