Description

Moexipril hydrochloride (RS-10085) is an orally active inhibitor of angiotensin-converting enzyme (ACE), and becomes effective by being hydrolyzed to moexiprila (hydrochloride). Moexipril hydrochloride exhibits antihypertensive and neuroprotective effects[1]-[4].

IC50 & Target

IC50: 2.1 nM (purified ACE from rabbit lung), 1.75 nM (ACE in rat plasma)[3]

In Vitro

Moexipril hydrochloride is devoid of anti-inflammatory properties and has no effect on platelet function[2].
Moexipril hydrochloride hydrolyzes to Moexiprilat, and Moexiprilat inhibits ACE in guinea pig serum as well as on purified ACE from rabbit lung with IC50s of 2.6 and 4.9 nM, respectively[2].
Moexipril hydrochloride (0.01 nM-0.1 mM) exhibits high potency against both plasma ACE and purified ACE from rabbit lung, with IC50s of 2.7 mM and 0.165 mM, respectively[3].
Moexipril hydrochloride (0-100 μM, 24 h) significantly reduced the percentage of damaged neurons in a dose-dependent manner[4].
Moexipril hydrochloride (0-100 μM, 24 h) significantly attenuates Fe2+/3+-induced neurotoxicity[4].
Moexipril hydrochloride dose not cause significant changes in the percentage of apoptotic neurons[4].

In Vivo

Moexipril hydrochloride can not cross the blood-brain barrier[1].
Moexipril hydrochloride (3 mg/kg, 30 mg/kg and 10 mg/kg, respectively; p.o.; once daily; 5 days) exhibits the a dose-dependent and antihypertensive effects in renal hypertensive rats, spontaneously hypertensive rats and perinephritic hypertensive dogs, respectively[3].
Moexipril hydrochloride (0.3 mg/kg, i.p.) significantly reduces the infarct area on the mouse brain surface in NMRI mice[4].
Moexipril hydrochloride (0.1 mg/kg, i.p.) significantly attenuates the cortical infarct volume in Long-Evans rats[4].

Animal Model: Spontaneously hypertensive rats[3]
Dosage: 30 mg/kg
Administration: Oral gavage; once daily; 5 days
Result: Caused a progressive lowering of mean blood pressure from pretreatment values of 180 +/- 7 mmHg to a trough on day 4 of 127 +/- 4 mmHg.
Dose-dependently decreased arterial blood pressure, and inhibited plasma and tissue ACE activity.
Animal Model: Renal hypertensive rats[3]
Dosage: 0.03-10 mg/kg
Administration: Oral gavage; once daily; 5 days
Result: Caused a dose-dependent decrease in blood pressure with a threshold dose of 0.3 mg/kg.
Lowered mean blood pressure by about 70 mmHg of 3 mg/kg.
Animal Model: Perinephritic hypertensive dogs[3]
Dosage: 10 mg/kg
Administration: Oral gavage; once daily; 5 days
Result: Caused a drop of mean blood pressure by 25 mmHg from pre-treatment control, which persisted for 24 h, by a rapid onset and a long duration of action.
Animal Model: NMRI mice (male, Permanent focal ischemia)[4]
Dosage: 0, 0.03, 0.3, and 3 mg/kg
Administration: Intraperitoneal injection (1 h before middle cerebral artery occlusion)
Result: Significantly reduced the infarct area on the mouse brain surface with a dose of 0.3 mg/kg, and other doses were not effective.
Animal Model: Long-Evans rats (male, Permanent focal ischemia)[4]
Dosage: 0, 0.01, 0.1 mg/kg
Administration: Intraperitoneal injection (1 h before middle cerebral artery occlusion)
Result: Significantly attenuated the cortical infarct volume from 114.4 to 98.2 mm as compared to non-treated animals in a dose of 0.01 mg/kg, without reducing the infarct volume of the rat brain at dosages >0.01 mg/kg.

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (3.89 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 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 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (3.89 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

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.
