Locomotor effects of cocaine, cocaine congeners, and local anesthetics in mice

Reith, Maarten E.A., Meisler, Bernard E., Lajtha, Abel·1985·Pharmacology Biochemistry and Behavior

Abstract

Spontaneous locomotor activity of mice was stimulated by IP administration of cocaine and its closely related phenyltropane analogs. In contrast, locomotion was inhibited by IP administration of cocaine congeners such as norcocaine, (+)-pseudococaine, and tropacocaine, and of isomers of phenyltropane analogs. Also inhibitory were the local anesthetics procaine, tetracaine, benzocaine, lidocaine, and prilocaine. The locomotor inhibition induced by IP norcocaine or tetracaine could be reversed by subsequent treatment with cocaine. Both cocaine and norcocaine were centrally stimulatory when injected intracerebroventricularly. The rank order of potencies of cocaine congeners and local anesthetics in depressing locomotion was similar to that of their potencies in interacting with sodium channels. From these results we infer that the locomotor depression induced by systemic administration of cocaine congeners results from a local anesthetic action involving inhibition of the ion conductance of sodium channels.

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.
