Odafosfamide
Based on 1 Customer Validation
Odafosfamide ((S)-OBI-3424) is a highly selective prodrug bis-alkylating agent activated by aldehyde-keto reductase 1C3 (AKR1C3(). Odafosfamide is highly cytotoxic to cell lines with high AKR1C3 expression. Odafosfamide exhibits antitumor activity in a variety of tumors with high AKR1C3 expression (such as liver cancer, non-small cell lung cancer, and leukemia). Odafosfamide can be used in cancer research.

AKR1C3 |
Odafosfamide (72-96 h) shows cytotoxicity against liver cancer cells (SNU-475, SNU-449, C3A, with IC50s of 15 nM, 45 nM, 5 nM, respectively) and non-small cell lung cancer cells (NSCLC) (NCI-H1944, NCI-H2228, NCIH1755, NCI-H1563, NCI-H2110, NCI-H1792, with IC50s of 2.3 nM, 0.21 nM, 8.2 nM, 2.5 nM, 1.1 nM, 4.5 nM, respectively) with high AKR1C3 protein and RNA expression levels[1].
Odafosfamide shows potent anti-leukemic activity against 19 leukemia cell lines representing B-ALL, T-ALL, and ETP-ALL (IC50s values were 60.3 nmol/L, 9.7 nmol/L, and 31.5 nmol/L, respectively)[2].

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: ≥ 2.5 mg/mL (5.43 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (5.43 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
