Synthesis and Evaluation of Triazolyl Dihydropyrimidines as Potential Anticancer Agents
Bibliographic record
Abstract
Novel N – triazolyl 3(a-f) and O-triazolyl (4a-f) derivatives of 4, 6-diaryl-1, 4-dihydropyrimidines were synthesized through mannich reaction. All compounds were characterized by physical and spectral data. These compounds were screened for in vitro efficiency in human breast cancer cell (MCF-7&MDA-MB-231) lines and found to have very good anti-proliferative activity.  Among all compounds of 4b, 3e, 4e endowed with lesser respective IC50 values of 31.94, 55.73, 55.03 µM in MCF-7 cells and 41.50, 35.28, 32.06 µM in MDA-MB 231 cells by MTT assay. In further studies, Compounds 4b, 3e, 4e were found to arrest cell growth at S phase in MCF-7 cells. In MDA-MB 231 cells, 4b, 4e were found to arrest the cells in S phase, and compound 3e found to arrest G2/M phase when compared to the standard drug tamoxifen, arrested S phase in MCF-7 cells and G0/G1 phase in MDA-MB 231 cells.

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.
