Biological Activity
|
A2B receptor 7 μM (Ki) |
Enprofylline (300 μM) completely blocks the release of IL-8 by N-ethylcarboxamidoadenosine (NECA)[1].
Enprofylline (10 μM) inhibits NECA (10 μM) induced proliferation in a concentration-dependent manner[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Human retinal endothelial cells (HRECs)
-
Concentration:10 μM
-
Incubation Time:24, 48, 72 hours
-
Result:NECA (10 μM) induced a time-dependent increase in HREC proliferation as measured by cell counts, achieving approximately 80% of the density of cells exposed to normal growth medium for 3 days.
Enprofylline (10 μM) completely blocked the proliferative effect of NECA when added concurrently with the analogue.
A high dose of Enprofylline (30 mg/kg) also decreases temperature compared with saline injection in female (but not in males) WT mice, but a low dose (7.5 mg/kg) has little effect on mouse temperature[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:A1RKO mice (were cross-bred to C57BL/6 mice for six generations) and A2ARKO mice (were backcrossed to C57BL/6 mice for more than 10 generations)[3]
-
Dosage:30 mg/kg
-
Administration:Intraperitoneally injected (bolus) at 2-h intervals
-
Result:Increased HR in male WT mouse from 529±23 to 590±20 and 562±20 after the low (7.5 mg/kg) and high dose (30 mg/kg), respectively.

Solvent & Solubility
DMSO : 62.5 mg/mL (321.85 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, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (10.71 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.
