Abstract
A new series of mono Mannich bases of 4'-hydroxychalcones 2a-e carrying a variety of aryl groups was synthesized and the in vitro cytotoxic activities of the new compounds were screened against PC-3 cell lines. Bioactivities of 2a-e, which are reported for the first time in this study, were compared against their precursor 4'-hydroxychalcones 1a-e. Compound 2b was found to be the most potent (IC(50 )= 3.7 microM) among the compounds synthesized. In addition, the compounds 1a-c and 2d showed moderate cytotoxicity. Incorporation of the 3'-piperidinomethyl group in 1b and 1d raised the potency by 1.68 and 2.19 times respectively and, therefore, seemed to be a noteworthy molecular modification. Correlations were noted between cytotoxicity and one or more physiochemical constants of the aryl ring as well as log P values for the compounds 2a-e. The significant improvement of cytotoxicity of 2b, 2d, and 2e against PC-3 cell lines compared with their chalcone precursors suggests that the incorporation of a piperidinomethyl group is a useful molecular modification and further development of these compounds as candidate cytotoxic agents may be warranted.

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
