Modulation of amyloid‐β aggregation and toxicity by inosose stereoisomers
Bibliographic record
Abstract
Amyloid-beta (Abeta) aggregation and amyloid formation are key pathological features of Alzheimer's disease, and are considered to be two of the major contributing factors to neurodegeneration and dementia. Identification of small molecule inhibitors that are orally available, have low toxicity and high central nervous system bioavailability is one approach to the potential development of a disease-modifying treatment for Alzheimer's disease. We have previously identified inositol stereoisomers as exhibiting stereospecific inhibition of Abeta aggregation and toxicity in vitro and in vivo. We report here the effects of inosose versus inositol stereoisomers on Abeta fibrillogenesis as determined using CD and fluorescence spectroscopy and negative-stain electron microscopy. The inososes differ from inositols by the oxidation of one of the hydroxyl groups to a ketone. These molecules help in the further elucidation of the structure-activity relationships of inositol-Abeta interactions and identify both allo-inositol and epi-2-inosose as in vitro inhibitors of Abeta aggregation.

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.
