HDIs have a long history of use in psychiatry and neurology as mood stabilizers and anti-epileptics. More recently they are being investigated as possible treatments for cancers, parasitic and inflammatory diseases. We found that HDAC inhibitors were a promising class of compounds against SARS-CoV-2. Five clinical HDAC inhibitors ( Table 1 ), including romidepsin, panobinostat, givinostat hydrochloride monohydrate, CAY10603, and sirtinol, could inhibit noticeably the spike/ACE2 mediated cell entry of SARS-CoV-2. These polyphenols modulate the activity of several proteins involved in cell growth and death in cancer cells, including histone deacetylases (HDAC), but the role of HDAC in senescence induced by Rsv and Quer is unclear. The HDAC inhibitor sodium butyrate (NaB) potentiated the pro-senescent effect of Rsv and Quer in human and rat glioma cell lines but not in normal rat astrocytes. HDAC inhibition, however, also upregulated PD-L1, thereby limiting the beneficial therapeutic effects.
