General description

A cell-permeable S-isobutyryl prodrug that is processed intracellularly to form the potent HDAC inhibitor NCH-31 (IC50 = 48 and 170 nM, respectively, using partially purified HDAC1 or HeLa nuclear extract) that is predicted to exhibit a similar HADC binding mode as that of SAHA with its sulfhydryl replacing SAHA′s hydroxamate as the active-site zinc-targeting group. NCH-51 is shown to exhibit comparable antiproliferative (mean IC50 = 3.8 µM vs. 3.7 µM for SAHA; 48 h treatment) and apoptotic activity as SAHA against various cancer cell lines, but not PBMCs from 4 healthy individuals (IC50 >30 µM with either drug), and the antioxidant N-Acetyl-L-Cysteine (NAC; Cat. No. 106425) at 2 mM is reported to abolish the cell-growth inhibition caused by either 3 µM NCH-51 or SAHA in the Multiple Myeloma U266 cultures. Half-life in human plasma at 37 °C = 24 h.

To identify the molecular mechanisms and novel therapeutic targets of late-onset Alzheimer's Disease (LOAD), we performed an integrative network analysis of multi-omics profiling of four cortical areas across 364 donors with varying cognitive and neuropathological phenotypes. Our analyses revealed thousands
