Synthesis and anticancer properties of 3-furan-2-yl-2-(4-furan/thiophen-2-ylthiazol-2-yl)acrylonitrile derivatives
Bibliographic record
Abstract
By the reaction of (4-furan-2-yl-thiazol-2-yl)- 3a and (4-thiophen-2-yl-thiazol-2-yl)- 3b acetonitriles with furfural 4 and 5-arylfurfyrals 5a-g 3-furan-2-yl-2-(4-furan/thiophen-2-ylthiazol-2-yl)acrylonitrile derivatives 6a-i were obtained. Anticancer activity screening was carried out within the framework of Developmental Therapeutic Program of the National Cancer Institute's (DTP, NCI, Bethesda, Maryland, USA). It was found out that (2E)-3-(2-furyl)-2-[4-(2-furyl)-1,3-thiazol-2-yl]acrylonitrile (6a) and 2-(4-thiophen-2-yl-thiazol-2-yl)-acrylonitriles 6h,i possessed low activity and 2-(4-furan-2-yl-thiazol-2-yl)acrylonitrile derivatives 6b-g showed moderate action. Compounds 6b-g were sensitive to cell lines of MDA-MB-468 and T-47D Breast Cancer. In this case cytotoxic effect was observed with a range of GP = -38.24 – 1.28%.

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.
