Repurposing investigation

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

AI-predicted activity

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 Posaconazole 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.
