描述 | Histone deacetylases (HDACs) remove the acetyl group from lysine residues of histones and other cellular proteins. Heightened HDAC activities are implicated in several disorders including chronic neurologic, inflammatory and metabolic conditions. UF010 is class I HDAC-selective with IC50s of 0.46, 1.33 and 0.19 μM against HDACs 1–3, respectively. In HCT116 cells, UF010 (2 μM for 1 h) consistently induced the accumulation of acetylated histones at all sites examined. Further, UF010 (2 μM) induced accumulation of acetylated p53 in both HCT116 and A549 cells after exposure to etoposide that inhibits DNA topoisomerase II, and induces double-stranded DNA breaks. It also notably stabilized p53 with or without etoposide treatment. It inhibited proliferation of the NCI-60 panel of cancer cell lines (including five breast cancer and seven colon cancer cell lines) with a mean GI50 of 2.94 μM. In MDA-MB-231 cells, UF010 mainly blocked G1/S transition with an increased G1 cell population and a reduced cell population in the S phase in a dose-dependent manner. Moreover, UF010 at 1 μM markedly slowed cell migration which is associated with metastatic progression[2]. | ||
作用机制 | The butyl side chain of UF010 fills a deep hydrophobic (“foot”) pocket[2]. |
