PTACH (compound 51) treatment elevates the levels of acetylated histone H4 and p21 in a dose-dependent manner.
In cancer cell growth inhibition assay, PTACH (compound 51) shows strong activity. PTACH inhibits various cancer cells with EC50 values of 2.3 μM, 9.1 μM, 3.0 μM, 2.6 μM, 1.1 μM, 4.5 μM, 2.4 μM, 5.0 μM, and 4.5 μM for MDA-MB-231, SNB-78, HCT116, NCI-H226, LOX-IMVI, SK-OV-3, RXF-631L, St-4, and DU-145 cells, respectively.
PTACH (NCH-51) augments the HIV-1 production in latently infected OM10.1 cells and such reactivation is associated with a loss of HDAC1 occupancy and subsequent hyperacetylation of histones in nuc-1 at the HIV-1 promoter.
