I already answered this in a sister comment. There are at least 3 candidates (Chloroquine , Remdesivir, Favipiravir ) and they are all unlikely to work.

Follow the article and read the summary, remdesivir was already trialed on a patient in Seattle: "The patient had visited Wuhan, returned to Seattle, began displaying symptoms, and was hospitalized on symptom day 3. By symptom day 8 X-ray showed clear lower respiratory tract viral pneumonia (diagnostic ‘ground glass’) and supplemental oxygen was started. Patient worsened, and intravenous antibiotics were started day 9. Patient worsened (proving viral pneumonia), so attending physicians consulted with FDA then had Gilead rush the experimental drug by air, with intravenous treatment starting day 10. Patient improved in 24 hours, was saved, and has since been discharged"

Importantly, "It did, however, show efficacy against SARS and MERS in vitro" So the drug is promising. Not saying it's a silver bullet but definitely promising.
