Description

MLN-4760 is a potent and selective human ACE2 inhibitor (IC50, 0.44 nM), with excellent selectivity (>5000-fold) versus related enzymes including human testicular ACE (IC50, >100 μM) and bovine carboxypeptidase A (CPDA; IC50, 27 μM).

IC50 & Target

IC50: 0.44 nM (Human ACE2), 27 μM (Bovine carboxypeptidase A)[1]
In Vitro

MLN-4760 is a potent and selective human ACE2 inhibitor (IC50, 0.44 nM), with excellent selectivity (>5000-fold) versus related enzymes human testicular ACE (IC50, >100 μM) and bovine carboxypeptidase A (CPDA; IC50, 27 μM)[1].
MLN-4760 effectively quenches cleavage of the 7-Mca-YVADAPK(Dnp) in rhACE2. MLN-4760 shows pIC50 at rhACE2 of 8.5±0.1 and at rhACE of 4.4±0.2. MLN-4760 also shows pIC50 at rhACE2 of 4.7±0.1, 6.9±0.1 and at ACE of 4.4±0.1, 6.2±0.1 in murine heart and mononuclear cells (MNCs), resepctively[2].

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: ≥ 2.5 mg/mL (5.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (5.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Rats[3]
In a related experiment to evaluate the role of central ACE2 in stroke, randomly assigned rats (n = 16) are treated centrally for five days prior to and three days after stroke with the ACE2 inhibitor MLN-4760 (100 μM infused at a rate of 0.5 μL/h) or sterile saline (0.9%) via intracerebroventricular infusion. Following endothelin-1 MCAO, neurological function is assessed at 4 h, 1 d, and 3 d, and brains are harvested at 3 d post-stroke for infarct volume analysis as above[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.
