"Gordon et al. identified BRD2/4 as a binding partner of viral protein E.

Resverlogix states that Apabetalone was shown to disrupt this interaction."

Jupe, I queried RVX IR Mar 24, 2020, to explain; "Apabetalone was shown to disrupt this transaction" :

Their response (below) Mar 25, 2020, not sure if this clarifies it.

"Apabetalone may combat the SARS CoV-2 virus by impeding viral entry and replication. Through its mechanism of action, apabetalone may potentially inhibit the expression of the receptor utilized by the novel coronavirus particles to gain entry into human cells and by disrupting viral host protein interactions."
