Repurposing investigation
This medicine is being investigated here for AI-predicted antimicrobial activity against E. coli, MRSA, K. pneumoniae and M. tuberculosis. It was surfaced computationally for further investigation; it is not an established treatment for these infections.

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 Grazoprevir 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.
