In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	1.060mg/ml (2.50mM)	Taking the 1 mL working solution as an example, add 50 μL of 21.2 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	NAMPT (in hematopoietic cells) 2.89 nM
In vitro	OT-82 is an effective nicotinamide phosphoribosyltransferase (NAMPT) inhibitor, thus inhibits the salvage pathway of NAD synthesis to kill the neoplastic cells of hematopoietic. The average IC50 is 13.03 nM in non-HP cancer cells and 2.89 nM in HP cancer cells.<sup><a class="sref" href="#s_ref">[1]</a></sup>
In vivo	OT-82 has therapeutic effect in subcutaneous(SC) and systemic mouse xenograft models of HP malignancies.<sup><a class="sref" href="#s_ref">[1]</a></sup>
