I haven't seen any evidence that (Xydroxy)chloroquine alone directly inhibits anything to do with the viral replication. The closest thing that I found is that Thymoquinone inhibits Mouse coronavirus replication and is generally protective of lungs:

Chloroquine is an antipyretic and relieves symptoms like fever from diseases like Malaria and dengue.

Chloroquine stops the inflammation from going out of control, which a good thing during an infection. But if you take it when you don't have an infection, it could stop you from detecting viruses in the first place.

The paper I cited in the previous comment mentions that Chloroquine is a TLR7 inhibitor. TLR7 is a receptor that senses of single-stranded viral RNA. https://www.sciencedirect.com/science/article/abs/pii/S01663...
