Abstract

fetched live from OpenAlex

AM1 semi-empirical and ab initio calculations were performed on certain synthetic polyamide conjugates of the aglycone of the minor groove binding antibiotic calicheamicin. Geometry optimized conformations and heats of formation were obtained. The binding of the optimized conformations of the drug to both alternating and non-alternating (AT)n and to (G)n x (C)n sequences were studied and the energies of binding were compared to each other. The results can be utilized in the design of novel enediyne-based drugs.

Teacher imitation

Not 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.
