Biological Activity
| ln Vivo | The process by which 6-chloropurine transforms into S-(6-punnyl)glutathione and then further breaks down into 6-mercaptopurine could be a contributing factor to the anticancer activity of 6-chloropurine. [1]. 6-It has been demonstrated that when given together, chloropurine and diazaserine exhibit synergistic anticancer effects against a range of mice cancers [1]. |

Solubility Data
| Solubility (In Vitro) |
DMSO : ~27.5 mg/mL (~177.92 mM) H2O : ~3 mg/mL (~19.41 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (17.79 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 27.5 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: ≥ 2.75 mg/mL (17.79 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 27.5 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. Solubility in Formulation 3: ≥ 2.75 mg/mL (17.79 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 27.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. Solubility in Formulation 4: 2 mg/mL (12.94 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication (<60°C).  (Please use freshly prepared in vivo formulations for optimal results.) |
