Synthesis of Polyvalent Inhibitors of Controlled Molecular Weight: Structure−Activity Relationship for Inhibitors of Anthrax Toxin
Bibliographic record
Abstract
We describe a novel method to synthesize activated polymers of controlled molecular weight and apply this method to investigate the relationship between the structure and activity of polyvalent inhibitors of anthrax toxin. In particular, we observe an initial sharp increase in potency with increasing ligand density, followed by a plateau where potency is independent of ligand density. Our simple strategy for designing polyvalent inhibitors of controlled molecular weight and ligand density will be broadly applicable for designing inhibitors for a variety of pathogens and toxins, and for elucidating structure-activity relationships in these systems. Our results also demonstrate a role for kinetics in influencing inhibitory potency in polyvalent systems. Finally, our work presents a synthetic route to polyvalent inhibitors that are more structurally defined and effective in vivo. This control over inhibitor composition will be generally useful for the optimization of inhibitor potency and pharmacokinetics, and for the eventual application of these molecules in vivo.

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.
