Abstract
The reactions of [Pt(dpma)(H2O)2]2+ (dpma = 2,2′-dipyridylmethylamine) and [Pt(dpk)(H2O)2]2+ (dpk = 2,2′-dipyridylketone) with the model nucleobases 1-methylthymine (1-MeT) and 1-methyluracil (1-MeU) were studied. Reaction products were characterized by 195Pt NMR spectroscopy and by X-ray structure analysis. The symmetric dpma and dpk diaqua complexes form dinuclear complexes with 1-methylthymine, acting as secondary bridging ligand via its N3 and O4 donor atoms. [Pt2(dpma)2(1-MeT)2](ClO4)2 · H2O (5) and [Pt2(dpk)(dpk · H2O)(1-MeT)2](PF6)2 · 4 H2O (6) both show a head-to-head arrangement. Biological tests show a significant in vitro antitumor activity of [Pt(dpk)Cl2] against the human glioma cell line U 87.

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
