Repurposing investigation

Tobramycin 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
  • MRSA4.7% 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.
  • E. coli4.6% 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.
  • K. pneumoniae51.6% AI-predicted activityAt or above 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.
  • M. tuberculosis66.4% AI-predicted activityAt or above the ≥40% mark this site uses to surface candidates.

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

50+registered studies name this medicine, for any condition. The registry search keeps the first 50, so there may be more. See them below.

Experimental

  • MRSA: measured active in 3 of 10 lab records
  • E. coli: measured active in 6 of 15 lab records

“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 Tobramycin 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.
