Reversible acetylation of lysine side chains on protein and enzyme surfaces is modulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs). Acetylation or deacetylation of protein lysine serves as a regulatory pathway for cellular transcription, cell cycles, and cellular metabolism.

HDAC6 is unique due to its ability to deacetylate a number of non-histone proteins and its preferred substrates. Selective inhibition of HDAC6 is recognized as a potential therapeutic approach for cancers, as it has been reported to interact with the transcription factor STAT3, a primary regulator of immune responses in the tumor microenvironment.

Researchers in this study designed a new HDAC6 inhibitor, named Suprastat, using in silico simulations. In vitro characterization of Suprastat demonstrated sub-nanomolar HDAC6 inhibitory potency and up to a thousand-fold HDAC6 selectivity over the other HDAC isoforms. In vivo studies showed that a combination of Suprastat and anti-PD1 immunotherapy enhances antitumor immune response, mediated by a decrease of protumoral M2 macrophages and increased infiltration of antitumor CD8+ effector and memory T-cells.
