Preparation, Characterization, and Screening of a High Affinity Organometallic Probe for α-Adrenergic Receptors
Bibliographic record
Abstract
An organometallic rhenium complex having high and selective affinity for α-adrenergic receptors is reported. A series of methoxyphenylpiperazinecarborane ligands complexed to the [Re(CO)(3)](+) core were prepared and the resulting organometallic compounds screened for binding to serotonin, σ, and adrenergic receptors as well as dopamine, serotonin, and norepinephrine transporters. An amide linked derivative, for which a single crystal X-ray structure was obtained, showed high and selective affinity toward α(1A), α(1D), and α(2C) adrenergic receptors with K(i) values of 17, 21, and 39 nM, respectively. A method to prepare the corresponding (99m)Tc complex was also developed where the resulting metallocarborane was shown to be stable and is therefore suitable for in vivo molecular imaging studies.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
