ISX9 is a neurogenic modulator. It mediates neuroD reporter gene induction via activation of Ca2+ influx, and increases expression of neurogenic differentiation 1 (NeuroD1) transcription factor. It induces neuronal differentiation in human cortical neuronal cells (HCN), adult mouse whole brain (MWB) and subventricular zone (SVZ) progenitors. ISX9 is also shown to induce cardiomyogenic differentiation of Notch-activated epicardium-derived cells in vitro.
