Bisantrene and COVID-19 Coronavirus, page-15

This preprint is based on computer modelling, not an actual trial. In actuality, it is far from being employed in clinical trial.
This preprint uses super computer to models the shapes of various drugs and the computer will calculate how these drugs interact with the virus. If interaction was to be found feasible, this was an indication as to bisantrene may potentially be a cure.

But as you can see from the tables, bisantrene is not on top of the table, it shows good result from the modelling but there are various other drugs possessing better interactions with the virus.

Anyway, this preprint does show bisantrene is a potential candidate for coronavirus which is highly promising
