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.) |
