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.

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.
