OT-82
Based on 2 publication(s) in Google Scholar
OT-82 is a potent, selective and orally active inhibitor of NAMPT. OT-82 is selectively toxic to cells of hematopoietic origin and?induces cell death in a NAD+ dependent manner. OT-82 is a promising antineoplastic agent for the study of hematological malignancies.

OT-82 (0.0001-10 μM; 72 hours) demonstrates tissue-selective (HP vs non-HP) cytotoxicity. It is against HP cell lines MV4–11, U937, RS4;11, HEL92.1.7 and PER485 cell growth with IC50 values of 2.11 nM, 2.70 nM, 1.05 nM and 1.36 nM, respectively. It also against nonHP cell lines MCF-7, U87, HT29, and H1299 cell growth with IC50 values of 37.92 nM, 29.52 nM, 15.67 nM and 7.95 nM , respectively[1]. OT-82 demonstrates cancer-selective (tumor vs normal) cytotoxicity. It more sensitive to BMMNC from leukemia patients, the IC50 values are 31 nM and 7.10 nM for AML and ALL donors, respectively. The IC50 value is 62.69 nM for BMMNC from healthy donors[1]. OT-82 (0.001-10 μM; 48 hours) inhibits recombinant NAMPT activity and causes dose-dependent reductions in cellular NAD and ATP concentrations in MV4–11 cells[1].OT-82 (0.01-100 nM; 48 hours) results in activation of caspase-3, an increase in the proportion of cells with sub-G1 DNA content, and depolarization of the mitochondrial membrane in MV4–11 cells[1].

Solvent & Solubility
DMSO : 100 mg/mL (235.59 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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 (4.90 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 (4.90 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
