Abstract

fetched live from OpenAlex

Glycosidase inhibition is a key process both in the pursuit of new therapeutic agents and in the drive to understand transition-state stabilisation by these remarkable enzymes. That isofagomine lactam (1) is an equally potent inhibitor of β-glucosidases and β-mannosidases (despite possessing a carbonyl group) adds to the emerging view that mannosidases and glucosidases harness distinct transition states; the B2,5 conformation for some retaining mannosidases and the 4H3 for glucosidases, both of which place O2 pseudo-equatorially.

Full frame distilled prediction

Teacher imitation

Not 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.
