生物活性

Omapatrilat is a dual inhibitor of the metalloproteases ACE and NEP with Ki values of 0.64 and 0.45 nM, respectively.

IC50 & Target

Ki: 0.45 nM (NEP), 0.64 nM (ACE)[1]; IC50: 8 nM (NEP), 5 nM (ACE)[2]

體外研究
(In Vitro)

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內研究
(In Vivo)

Omapatrilat demonstrates excellent blood pressure lowering in a variety of animal models characterized by various levels of plasma renin activity and significantly potentiates urinary sodium, ANP, and cGMP excretion in a cynomolgus monkey assay. Omapatrilat decreases mean arterial pressure (MAP) approximately 40 mmHg below baseline from 10 to 24 h. Oral administration of omapatrilat at 100 μM/kg once daily results in a 38 mmHg decrease in systolic blood pressure at day three as compared to vehicle [2]. Omapatrilat is widely used in experimental protocols related to hypertension and heart failure. Chronic oral administration of omapatrilat reduces aortic leakiness and atheroma formation with enhanced endothelial independent vasorelaxation to ANP[3]. Omapatrilat causes significant inhibition of plasma ACE and increased plasma renin activity in rats[4].

動物實驗:

請根據您的 實驗動物和給藥方式 選擇適當的溶解方案。

以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液,再依次添加助溶劑:
——為保證實驗結果的可靠性,澄清的儲備液可以根據儲存條件,適當保存;體內實驗的工作液,建議您現用現配,當天使用;
以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比;如在配制過程中出現沉淀、析出現象,可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請依序添加每種溶劑: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 4.25 mg/mL (10.40 mM); 澄清溶液

    此方案可獲得 ≥ 4.25 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 42.5 mg/mL 的澄清 DMSO 儲備液加到 400 μL PEG300 中,混合均勻;再向上述體系中加入 50 μL Tween-80,混合均勻;然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL

    生理鹽水的配制:將 0.9 g 氯化鈉,溶解于 ddH?O 并定容至 100 mL,可以得到澄清透明的生理鹽水溶液。
  • 方案 二

    請依序添加每種溶劑: 10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (6.12 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液,此方案實驗周期在半個月以上的動物實驗酌情使用。

    1 mL 工作液為例,取 100 μL 25.0 mg/mL 的澄清 DMSO 儲備液加到 900 μL玉米油中,混合均勻。

Kinase Assay
[1]

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3][4]

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
