β‐phenylethylidenehydrazine, a novel inhibitor of GABA transaminase
Bibliographic record
Abstract
Abstract Phenylethylidenehydrazine (PEH), a proposed metabolite of phenelzine (PLZ), was synthesized in our laboratories and administered to rats in a series of time‐ and dose–response studies. Phenelzine is a monoamine oxidase (MAO) inhibiting antidepressant/antipanic drug that also causes marked elevations of brain levels of the inhibitory neurotransmitter (γ‐aminobutyric acid (GABA). Like PLZ, PEH inhibited GABA transaminase (GABA‐T) and caused marked, long‐lasting increases in rat brain levels of GABA. The addition of the double bond in PEH caused a marked decrease in its ability to inhibit MAO compared to PLZ. Given the ability of PEH to elevate GABA levels and its lack of significant effect on MAO, it may be a very effective and safe tool with which to study the role of GABA in anxiety disorders and may be a potentially useful compound to test against seizures, ischemia, mania, and stroke.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
