Repurposing investigation

Pyrazinamide is already an antimicrobial, so it is not counted among the repurposing candidates. Its AI-predicted activity is shown below for reference.

AI-predicted activity

AI prediction · nothing measured
  • MRSA17.0% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • E. coli15.8% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • K. pneumoniae7.6% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • M. tuberculosis13.0% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates. This medicine was in the model's training data, so this is recall, not a new prediction.

A model’s estimate of laboratory activity against each pathogen species. It is not clinical effectiveness.

“Active” means the measured value reached this project’s laboratory cutoff (10 µM or stronger). A laboratory result does not show an effect in patients.

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 measured

Other repurposing candidates: approved medicines besides Pyrazinamide 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.
