1-(3-Aminomethyl-4-hydroxyphenyl)-3-pyridinyl-2-propen-1-ones: A novel group of tumour-selective cytotoxins
Bibliographic record
Abstract
Two series of 1-(3-aminomethyl-4-hydroxyphenyl)-3-pyridinyl-2-propen-1-ones, designed as novel cytotoxins, were synthesized. The compounds had low CC50 values in the micromolar range against HL-60 promyelocytic leukemic cells and HSC-2, HSC-3 and HSC-4 oral squamous cell carcinomas. The CC50 values of these compounds were higher towards non-malignant HGF (gingival fibroblasts), HPC (pulp cells), and HPLF (periodontal ligament fibroblasts) cells, which reveals the tumour-selectivity of these enones. A representative compound 4c caused cleavage of PARP1 in HSC-2 cells but not in HGF cells, which may be a contributing factor to the tumour-selectivity.

How this classification was reachedexpand
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.
