Biological Activity
IC50: 3.1 nM (NAMPT), 0.84 μM (CSF1R)[1]
To assess its selectivity, specificity, and effects on cellular NAD+ levels, LSN3154567 is characterized in various biochemical and cellular assays. LSN3154567 inhibits purified NAMPT with an IC50 of 3.1 nM. When tested against a panel of human kinases (>100; CEREP Kinase panel), it does not exhibit any significant activity (i.e.: IC50≥1 μM) against the kinases tested except CSF1R (IC50≈0.84 μM). LSN3154567 exhibits a broad spectrum of anticancer activity. To assess its anticancer activity, LSN3154567 is tested against a number of different types of cancer cell lines cultured in the absence or presence of nicotinic acid (NA) (10 μM). LSN3154567 exhibits a potent antiproliferative activity against many cell lines in the absence of NA[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.96 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (4.96 mM); Clear solution

Protocol
Cell[1]
The cell lines used as following: A2780 and KM-12, KMS-11 and MKN-74, OPM-2 and Kelly; and all other cancer cells. The identity of these cell lines is not tested or verified prior to use in this study. Cells are seeded in 96-well plates, cultured overnight, and treated with LSN3154567 (0.03 to 1,000 nM)±NA (10 μM) in duplicate at 37°C in 5% CO2 for 72 hours. Staurosporine (10 μM) is used as positive control. Cell viability is determined by a CytoTox-Glo Cytotoxicity assay kit[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice[1]
Male CD-1 mice are dosed with LSN3154567 at 2 mg/kg intravenously in 20% Captisol (w/v), 25 mmol/L NaPO4, pH 2, q.s. formulation or 2 mg/kg orally in the same vehicle in a cross over design with 3-d wash period in between two arms. Blood samples are obtained through retro orbital at 0, 0.08 (IV only), 0.25, 0.75, 2, 4, 8, and 24 hours and frozen until analysis. For exposure analysis, blood samples (≈20 μL) are obtained through tail clipping at 0.5, 1, 2, 4, 8, and 24 hours. The samples are collected into EDTA-coated capillary tubes and spotted onto Whatman DMPK-C DBS collection cards.
Rats and Dogs[1]
Female rats or male and female dogs are dosed with LSN3154567 orally in the same vehicle. For NA rescue studies, NA is formulated in phosphate buffered saline (pH 7.4). Rats are given LSN3154567 orally once daily at 20, 40, or 80 mg/kg for two cycles of 4 days with 3 days between the first and second cycles. Dogs are also dosed orally at 1 or 2.5 mg/kg (without NA) or at 5 mg/kg (with NA; BID) for 4 days. Exposure is obtained and analyzed as described above.
