Repurposing investigation

This medicine is being investigated here for AI-predicted antimicrobial activity against M. tuberculosis. It was surfaced computationally for further investigation; it is not an established treatment for this infection.

AI-predicted activity

AI prediction · nothing measured
  • MRSA14.2% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • E. coli17.8% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • K. pneumoniae10.4% AI-predicted activityBelow the ≥40% mark this site uses to surface candidates.
  • M. tuberculosis85.2% 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.

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

“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 Acetazolamide 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.
