Description

General description

NU9056, a disulfane compound, is reported to be a potent inhibitor of lysine acetyltransferase 5 (KAT5). NU9056 inhibits protein acetylation in prostate cancer cell lines. It acts against histone acetyltransferase KAT5/Tip60 than PCAF, p300, and GCN5 in cell-free HAT activity assays (IC50 ≤2, ≤36, ≤60, and >100 µM, respectively) and effectively reduces H3K14, H4K8, H4K16, but not α-tubulin, acetylation level in LNCaP prostate cancer cells (max inhibition at 5-10 µM). Shown to induce cell cycle arrest and apoptosis (17 to 24 µM) in LNCaP cultures and exhibit antiproliferation activity in both androgen-responsive and androgen-independent CaP cultures (GI50 from 7.5 to 27 µM).
