Biological Activity
Ki: 0.45 nM (NEP), 0.64 nM (ACE)[1]; IC50: 8 nM (NEP), 5 nM (ACE)[2]
Omapatrilat exhibits high potency for NEP, NEP2 and ACE, moderate strong activity against APP, but low activity against ECE1 (Ki=0.45, 25, 0.64, 250 nM) [1]. In vitro autoradiography using the specific NEP inhibitor radioligand 125I-RB104 and the specific ACE inhibitor radioligand 125I-MK351A show omapatril at (10 mg/kg) causes rapid and potent inhibition of renal NEP and ACE, respectively, for 24 h[4].

Solvent & Solubility
DMSO : ≥ 31 mg/mL (75.88 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
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, stored under nitrogen). 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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 4.25 mg/mL (10.40 mM); Clear solution
This protocol yields a clear solution of ≥ 4.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (42.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Protocol
Omapatrilat is dissolved in 100% DMSO at 10 mM and diluted to 1% DMSO. NEP, NEP2, ACE and APP assays are performed at pH 7.4. The reaction buffer for NEP and NEP2 contained 50 mM HEPES, 140 mM NaCl, 10 mM KCl, 0.01% BSA. The buffer for ACE contained 100 mM Tris-HCl, 50 mM NaCl, 10 μM ZnCl2, and the buffer for APP contained 100 mM HEPES and 0.01% BSA. Assays are performed in 100 μL volume in black 96-well round-bottom plates at room temperature. Reactions are continuously monitored with excitation and emission wavelengths appropriate for each respective substrate. Enzyme velocity is determined from the linear part of the reaction[1].

Rats: Sprague Dawley rats are weighed and then gavaged with vehicle (5% arabic gum) or omapatrilat (0.1, 1, 10 mg/kg) (n 5 6 rats/group). Rats are killed by decapitation at 1 h after gavage. Trunk blood is collected into prechilled tubes containing EDTA/aprotinin for the measurement of PRA and into prechilled heparin tubes for the measurement ofplasma ACE[4].
Rabbits: Omapatrilat is dissolved in drinking water. Rabbits are divided into 2 groups with 1% cholesterol diet, placebo-treated group and omapatrilat-treated group, and administrated (12 mg/Kg/day omapatrilat) once daily for 8 weeks. To demonstrate the acute effect of omapatrilat, urine is collected after omapatrilat or placebo administration for 24 hours at day 1, and urine volume, cGMP and ANP levels are assessed[3].
