Based on 23 publication(s) in Google Scholar
Captopril (SQ 14225) hydrochloride, antihypertensive agent, is a thiol-containing competitive, orally active angiotensin-converting enzyme (ACE) inhibitor (IC50=0.025 μM) and has been widely used for research of hypertension and congestive heart failure. Captopril hydrochloride is also a New Delhi metallo-β-lactamase-1 (NDM-1) inhibitor with an IC50 of 7.9 μM.

IC50 & Target
ACE[1]
In Vitro
Captopril (SQ 14225) hydrochloride has been shown to have similar morbidity and mortality benefits to those of diuretics and beta-blockers in hypertensive patients. Captopril hydrochloride 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 hydrochloride 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].

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.

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.
