Descrizione

Descrizione generale

A cell-permeable phenylsulfonyloxyiminocyclohexadienone compound that acts as a potent, selective, and reversible inhibitor of p300 histone acetyl transferase (IC₅₀ = 1.98 µM). Shown to occupy Ac-CoA binding pocket of p300, and less potent to CBP, PCAF, GCN5 and GNAT. Suppresses Histone H3 and H4 acetylation in triple negative breast cancer cell line MDAMB-468 as well as in HCT116 cell line and blocks p300-mediated STAT3 phosphorylation in pancreatic cancer cell line MIA Paca-2. Does neither inhibit the activities of histone deacetylases 1, 6, and 11 nor 8-diverse histone methyltransferases tested (DOT1, EZH1, G9a, PRMT1, SETD2, SET7-9, SMYD2, and SUV39H2). Reported to suppress tumor growth in mice bearing tumor xenografts of MDAMB-468 cell line (at 500 µg/100 µl, i.p. twice a week).
