The inhibitors of histone deacetylases (HDACs) have shown promising neuroprotective and neuroactive properties. A set of pan- and isoform-specific HDAC inhibitors were evaluated for neurotrophic activity on Neuroscreen-1 (NS-1) cells, a subclone of PC-12 (rat pheochromocytoma) cells.
The HDAC inhibitors were tested alone and in combination with nerve growth factor (NGF). An in vitro method has been standardized that measures neurite outgrowth along with cytotoxicity of test compounds in a single assay. The neurotrophin signaling pathways were interrogated with selective inhibitors of MEK1/2 (PD98059/U0126) PI3K (LY294002) and TrkA (GW441756) and phosphorylation of target kinases. Associated factors namely, acetylation of histones …
