Nootropic effects of ACE inhibitors in mice
Abstract
The angiotensin converting enzyme (ACE) inhibitors captopril and enalapril and the nootropic piracetam reduced the amnesiogenic effects of cerebral electroshock treatment in mice. These compounds also directly improved passive-avoidance learning if administered before the learning trial. When given immediately after the learning trial, captopril and piracetam were active, but not enalapril. Captopril, but neither enalapril nor piracetam, facilitated memory retrieval after a 2-month retention interval. Unlike those of piracetam, the memory-improving effects of captopril and enalapril are not established by aldosterone-receptor blockade, suggesting that the two types of drug act via different mechanisms of action.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
