Abstract

In order to develop a better dopamine receptor radioligand, [3H[apomorphine was prepared and tested for dopamine-like binding properties in both calf and human brain tissues. Specific binding of [3H]apomorphine was defined as that binding which occurred in the presence of 1 muM (-)-butaclamol (an inactive neuroleptic) minus that occurring in the presence of 1 muM (+)-butaclamol (active neuroleptic). The specific binding was saturable, the number of sites being double that of specific [3H]dopamine binding, and occurred primarily in dopamine-rich regions of postmortem human brains. The binding had a dissociation constant of 0.9 nM for human caudate (2 nM for calf caudate) and was blocked by dopamine and norepinephrine, but not by isoproterenol or (-)-propranolol, distinguishing it from a beta-adrenergic receptor. Since there was little desorption of [3H]apomorphine, the ligand permits extensive washing during routine assays for dopamine receptors, and facilitates biochemical purification of the receptor.

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.
