Biological Activity


ln Vitro In prelabeled GH3 cells, EWP 815 decreases the basal breakdown rate without influencing the thyrotropin-releasing hormone (TRH; 0.03 mM)-stimulated inositol phospholipid breakdown [1]. The soluble enzyme IC50 is 83 mM, whereas the granzyme is 71 mM. With an average [3H]Ins(1,4)P2 recovery of 2.6[1], EWP 815 (30 μM; 1 hour) suppresses Ins(1,4)P2 phosphatase more than Ins(1,4,5)P3 5-phosphatase. With an IC50 of 6 μM and 8 μM, respectively, EWP 815 (6, 8 μM; 10 min) inhibits the dephosphorylation of [3H]Ins(1,4,5)P3 5-phosphatase in both the soluble and particulate fractions[1]. Without changing Ins (1,4,5)P3 binding, EWP 815 (3-300 μM; 30 min) reduces the amount of inositol phospholipid produced in response to thyrotropin-releasing hormone (TRH) stimulation (100 nM) by 30% at 100 μM and 1.8% at 300 μM, respectively[1].
ln Vivo Mice treated intraperitoneally with EWP 815 (50 mg/kg; 30 minutes prior to sacrifice) have their dopamine β-hydroxylase activity inhibited [2].
Animal Protocol Animal/Disease Models: Female mice (20 g) [2]
Doses: 50 mg/kg
Route of Administration: intraperitoneal (ip) injection; 30 minutes before sacrifice Hydroxylase. The amount of 3H-α-Me-NA was diminished by 12%.

Solubility Data


Solubility (In Vitro) DMSO : ~50 mg/mL (~142.62 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 1.25 mg/mL (3.57 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 12.5 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 2: ≥ 1.25 mg/mL (3.57 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 12.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)

*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.
