Abstract
A series of 4'-aminochalcones 1 and related maleamic acids 2 and Schiff bases 3 were designed and synthesized as candidate cytotoxic agents. The atomic charges on different atoms of representative compounds were calculated. Evaluation of the enones 1-3 against human Molt 4/C8 and CEM T-lymphocytes as well as murine P388 and L1210 leukemic cells revealed that approximately 40% of the IC50 values generated were less than 10 microM. In some cases cytotoxicity was correlated with the Hammett sigma values of the aryl substituents and less frequently with the aryl Hansch pi values. Evidence was obtained that in general these compounds displayed selective toxicity for certain malignant cells and were well tolerated in mice. This study has revealed various directions whereby the project may be amplified in the future with a view to finding compounds with increased cytotoxicity to tumour cells.

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
