Synthesis, anticancer evaluation, and molecular docking study of some arylidenehydrazono analogues
Bibliographic record
Abstract
A series of 2-(arylidenehydrazono)-5-(2-oxo-2-arylethyl)thiazolidin-4-one derivatives was synthesized, characterized by spectral analyses and evaluated for their in vitro antitumor activity. The IC50 determination of compounds was investigated on the human breast cancer cell line MCF-7. Among the series, compounds 3, 6, 10, 16, 17, and 24 showed remarkable anticancer activity with mean IC50 values 2.34, 0.73, 2.69, 3.40, 1.18, and 1.76 µg/mL, respectively, against MCF-7 cancer cells. Compound 16 enhanced the concentration of caspase-9, inhibited the concentration of Ki67 and showed a profound reduction in the amount of MMP9 secreted into the medium of MCF-7-treated cells. Furthermore, compound 16 revealed anti-angiogenic activity through downregulation of the concentration of VEGF in the medium of MCF-7-treated cells. Compound 16 exerted cytotoxic effects on MCF-7 tumor cells via antiproliferative, apoptotic, anti-angiogenic, and antimetastatic activities. Molecular docking methodology was performed for the most effective anticancer compounds to rationalize the possible interactions with active site of VEGFR-2 enzyme.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
