Repurposing investigation
No supported pathogen reaches ≥40% AI-predicted activity for Vitamin A, so it is not among the repurposing candidates. Its predictions are shown below.

AutoDock Vina, one experimentally solved protein per pathogen. This project’s screening target is -7.0 kcal/mol, its own mark rather than a universal cutoff. A docking score is a structural hypothesis, not proof of binding, and requires experimental validation.
Other medicines to investigate
AI prediction · nothing measuredOther repurposing candidates: approved medicines besides Vitamin A with AI-predicted activity ≥40% against the chosen pathogen, leaving out existing antimicrobials. They are computational candidates for further investigation, not alternatives and not recommendations.
Sorted by AI-predicted activity, high to low. The order is not a ranking of which medicine is better.
