Uncovering Structure–Activity Relationships of Phenethylamines: Paving the Way for Innovative Mental Health Treatments
Bibliographic record
Abstract
The rapidly evolving psychedelic industry has garnered considerable attention due to 3,4-methylenedioxymethamphetamine-assisted psychotherapy’s ground-breaking success in treating moderate-to-severe Post-traumatic Stress Disorder in two Phase 3 clinical trials. This has opened Pandora’s box for the development of innovative therapeutic modalities. Of particular interest are the phenethylamines and their ability to inhibit monoamine transporters. In this study, we employed the quantitative structure–activity relationship methodology to develop three vigorous models for the reuptake of serotonin, dopamine, and norepinephrine through monoamine transporters. These models were thoroughly validated using various criteria, including fitting ( R 2 DAT = 0.869, R 2 SERT = 0.828, and R 2 NET = 0.887), internal ( Q 2 loo DAT = 0.795, Q 2 loo SERT = 0.784, and Q 2 loo NET = 0.820), and external (RMSEext DAT = 0.373, R 2 ext DAT = 0.831, RMSEext SERT = 0.200, R 2 ext SERT = 0.955, RMSEext NET = 0.318, and R 2 ext NET = 0.711) criteria.

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.
