Abstract

fetched live from OpenAlex

Abstract A convergent strategy to access high‐valency iminosugar clusters based on two successive CuI‐catalysed azide–alkyne cycloadditions is reported. The key step of this approach relies on the grafting of azide‐armed trivalent iminosugar dendrons onto polyalkyne “clickable” scaffolds, thus tripling their initial valency. As a proof of concept, the synthesis of cyclodextrin‐based clusters containing the highest number of peripheral iminosugar ligands reported to date has been achieved. Evaluation of these compounds as mannosidase inhibitors revealed one of the strongest multivalent effects observed so far in glycosidase inhibition.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
