Abstract
Abstract magnified image The synthesis of a series of bis‐8‐hydroxyquinoline‐ and bis‐8‐hydroxyquinaldine‐substituted N ‐benzyl or thiophenyl amines and their corresponding bis‐8‐hydroxyquinoline is reported. In vitro growth inhibitory effects of both series have been evaluated. It has been observed that analogs from the bis‐8‐hydroxyquinoline series exert nanomolar range activity, whereas the antiproliferative activity of the corresponding analogs from the bis‐8‐hydroxyquinaldine series was found to be drastically lower. Molecular docking and chemical–physical properties account for these observed growth inhibitory differences between the two series of analogs, which differ only by the presence of a methyl group at the 2 position of the heterocyclic ring.

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 it
