EC50: 10.2 nM (dCK)[1]
|
|---|---|
| ln Vitro |
For the purpose of suppressing dCK activity in CEM T-ALL cells, (S)-DI-87 has a larger IC50 value (IC50=468 nM) (IC50=3.15 nM) than DI-87 ((R)-DI-8) [1]. When gemcitabine, a dCK-dependent nucleoside analog prodrug with an EC50 of 10.2 nM, is applied to human cell line CCRF-CEM (CEM) cells for 72 hours, DI-87 (1 μM) protects the cells against its antiproliferative effects[1].

| ln Vivo |
Oral gavage of DI-87 (5-25 mg/kg) results in total inhibition of dCK within 27 hours, and full recovery of enzyme function by 36 hours at the 25 mg/kg dose[1]. Plasma concentrations of DI-87 (10–50 mg/kg; oral) range from 1 to 3 hours, while its plasma half-life is 4 hours[1]. Growth of male NSG mice with CEM tumors with DI-87 (10 mg/kg/day or 25 mg/kg/day; oral; for 16–18 days) in combination with thymidine (2 g/kg; intraperitoneally; twice daily) decreases tumor engraftment[1].

| Animal Protocol |
Animal/Disease Models: 8-12 week-old male or female NSG mice with CEM tumor xenografts[1]
Doses: 5, 10, 25 mg/kg Route of Administration: po (oral gavage) Experimental Results: The 25 mg/kg dose demonstrated full dCK inhibition for 27 hrs (hours) , and enzyme activity fully recovered by 36 hrs (hours). The 10 mg/kg dose resulted in full inhibition with recovery initiating at the 12 hrs (hours) time point. The 5 mg/kg dose resulted in minimal dCK inhibition with rapid recovery. Animal/Disease Models: Female NSG mice with CEM tumors[1] Doses: 10, 25, or 50 mg/kg Route of Administration: Oral Experimental Results: Had plasma concentrations of between 1 and 3 hrs (hours) and plasma half-life of 4 hrs (hours). Had tumor concentrations lower than plasma and had a later, more sustained peak at 3-9 hrs (hours). |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.97 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 25.0 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: 2.5 mg/mL (4.97 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 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: ≥ 2.5 mg/mL (4.97 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.

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.
