In Vivo Efficacy Study

Histological Imaging/Staining

: Captopril purchased from MedChemExpress. Usage Cited in: Allergy. 2025 Nov 14. [Abstract]; Representative images of feet collected 30 min post-Evans Blue (EB) injection. Mice were assigned to five groups: WT control, Serping1^+/− control, WT + Captopril (2.5 mg/kg; i.v.), Serping1^+/− + Captopril + PBS, and Serping1^+/− + Captopril + AAV-NG-ABE8e. Captopril elicited significant Evans blue leakage.

: Captopril purchased from MedChemExpress. Usage Cited in: Allergy. 2025 Nov 14. [Abstract]; Representative intravital confocal images showing real-time FITC-dextran extravasation from intestinal microvasculature. Mice were assigned to: WT control, Serping1^+/− control, WT + Captopril (2.5 mg/kg; i.v.), Serping1^+/− + Captopril + PBS, and Serping1^+/− + Captopril + AAV-NG-ABE8e. By 30 min, Captopril-treated mice demonstrated pronounced FITC-dextran extravasation—both in area and fluorescence intensity—relative to WT and Serping1^+/− controls.

: Captopril purchased from MedChemExpress. Usage Cited in: Nat Commun. 2023 May 2;14(1):2523. [Abstract]; Serum BK levels from sWAT from WT male mice treated with 40 mg/kg/day Captopril or 70 mg/kg/day Enalapril by gavage once a day for 21 days. The results showed that Captopril significantly increased serum BK levels.

In Vitro

Captopril (SQ 14225) has been shown to have similar morbidity and mortality benefits to those of diuretics and beta-blockers in hypertensive patients. Captopril has been shown to delay the progression of diabetic nephropathy, and enalapril and lisinopril prevent the development of nephropathy in normoalbuminuric patients with diabetes^[4].
An equimolar ratio of the cis and trans states of Captopril exists in solution and that the enzyme selects only the trans state of the inhibitor that presents architectural and stereoelectronic complementarity with its substrate binding groove^[5].

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 (11.51 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 (11.51 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (11.51 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
