Purity: ≥98%
Pentostatin (CI-825; Deoxycoformycin), a purine analog and an anticancer of the antimetabolite class, is an irreversible inhibitor of adenosine deaminase with Ki of 2.5 pM. Pentostatin acts by mimicking the nucleoside adenosine and thus inhibits the enzyme adenosine deaminase, interfering with the cell's ability to process DNA. Cancer cells generally divide more often than healthy cells; DNA is highly involved in cell division (mitosis) and drugs which target DNA-related processes are therefore more toxic to cancer cells than healthy cells. Pentostatin is used to treat hairy cell leukemia. It is given by intravenous infusion once every two weeks for three to six months. Additionally, pentostatin has been used to treat steroid-refractory acute and chronic graft-versus-host disease. Pentostatin is also used in chronic lymphocytic leukemia (CLL) patients who have relapsed.
ln Vivo |
Pentostatin (2 mg/kg) combined with cordycepin (2 mg/kg) was 100% effective against Trypanosoma evansi-infected mice. Increased levels of some biochemical parameters, especially liver enzymes, were accompanied by histological lesions of the liver and kidneys. Pentostatin alone has no effect on infected groups. All dogs developed granulocytopenia with granulocyte counts <500 cells/μL starting on day 4. Thrombocytopenia (<20,000 platelets/μL) begins on day 7 after HCT, with a nadir of 3000 to 14000 platelets/μL [1].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (7.75 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (7.75 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (7.75 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
