Webb19 dec. 2008 · Histone deacetylase (HDAC) inhibitors, including various benzamides and hydroxamates, ... (106), is a class I HDAC inhibitor, demonstrating no activity against class II HDACs. 106 is a slow, tight-binding inhibitor of HDACs 1, 2, and 3, although inhibition for these enzymes occurs through different mechanisms. Webb15 aug. 2024 · In our previous study, benzamide-based HDAC inhibitor 106 and MS275 shows slow and tight binding to HDAC enzyme, while compound 4 exhibits reversible binding with fast-on/fast-off profile. Therefore, the enzymatic binding profile of bezamide-based inhibitors is not only dependent ZBG, but also rely on the cap and linker. greenboard in showers
