Abstract
Herein, we describe the design, synthesis and biological evaluation of a series of novel non-nucleotide sulfonylurea and sulfonylthiourea based small molecule inhibitors of h-ENPP1, h-ENPP3 and e5′NT. Among the tested compounds, 3b inhibited h-ENPP1 with an IC50 value of 0.11 ± 0.01 µM. Similarly, 4b was found to be the most potent inhibitor tested against h-ENPP3 with an IC50 value of 0.038 ± 0.02 µM. Compound 3a revealed remarkable inhibitory potency against human ecto-5′-nucleotidase with an IC50 value of 0.83 ± 0.01 µM while compound 3b possessed IC50 value of 0.26 ± 0.05 µM against rat ecto-5′-nucleotidase. Antiproliferative activity of novel sulfonylurea and sulfonylthiourea derivatives was investigated on breast cancer cell line (MCF-7). Compound 4a showed anticancer activity against MCF-7 cell line with percentage inhibition of 64 and successfully arrested the viability of cancer cells. The compounds were not cytotoxic to the normal cells derived from baby hamster kidney (BHK-21).

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 it
