I agree in general, but in this case the extra information is sort of irrelevant - do we really need to say "in this flavivirus?" Something much better as an overall description might be "Remdesivir is an adenosine analogue that chain terminates RNA dependent rna synthesis, inhibiting viral replication" or something like that. Use the molecule name instead of a label, general instead of specific, and if you are talking about dengue in particular - why refer to it as a flavivirus? Who cares in this context? Just say "dengue" again instead of "this flavivirus." And, I don't think the drug has been empirically demonstrated to inhibit cytokine storms etc, that should qualify the description of the imputed mechanism of action by clarifying that it's the hypothesized effect the drug will have.
