An Improved Class of Sugar-Binding Boronic Acids, Soluble and Capable of Complexing Glycosides in Neutral Water
Bibliographic record
Abstract
This study describes a new class of carbohydrate-binding boronic acids. ortho-Hydroxymethyl phenylboronic acid (boronophthalide) was shown to be superior to the well-established dialkylamino ("Wulff-type") analogues, and it is more soluble in aqueous solvents. The most significant finding in this work is the surprising ability of ortho-hydroxyalkyl arylboronic acids to complex model glycopyranosides under physiologically relevant conditions. These boronic acid units appear to complex hexopyranosides mainly using their 4,6-diol. This behavior is significant because a majority of cell-surface glycoconjugates present free 4,6-diols. Thus, conjugatable forms of these boronic acids could be used in the design of oligomeric receptors and sensors to exploit multivalency effects. Such receptors could dramatically expand the potential of boronic acids toward the selective recognition of cell-surface glycoconjugates.

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.
