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

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

Documented evidenceClinical
49registered studies name this medicine, for any condition. See them below.
Experimental
No evidence found
No laboratory measurement against the four pathogens in the ChEMBL records loaded here.
Docking
Computational · nothing measuredAutoDock 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 Opicapone 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.
