INHIBITION OF GABA UPTAKE IN RAT BRAIN SLICES BY NIPECOTIC ACID, VARIOUS ISOXAZOLES AND RELATED COMPOUNDS

Krogsgaard‐Larsen, P., Johnston, G. A. R.·1975·Journal of Neurochemistry

Abstract

—A variety of isoxazoles structurally related to muscimol (3‐hydroxy‐5‐aminomethylisoxazole) were tested as inhibitors of the uptake of GABA and some other amino acids in rat brain slices, and of the activity of the GABA‐metabolizing enzymes l‐glutamate 1‐carboxylyase and GABA:2‐oxo‐glutarate aminotransferase. A bicyclic derivative, 4,5,6,7‐tetrahydroisoxazolo[4,5‐c]pyridin‐3‐ol, proved to be a more potent inhibitor of GABA uptake than muscimol. Structure‐activity studies on this derivative, which appeared to be a competitive inhibitor of GABA uptake, led to the findings that nipecotic acid (piperidine‐3‐carboxylic acid) is a powerful non‐competitive inhibitor of GABA uptake, and that perhydro‐1,2‐oxazine‐6‐carboxylic acid is a relatively weak competitive inhibitor of GABA uptake.

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.
