Description: Neurogenic agent; induces neuronal differentiation of SVZ progenitors and also induces cardiomyogenic differentiation
Chemical Name: N-Cyclopropyl-5-(2-thienyl)-3-isoxazolecarboxamide
Purity: ≥98% (HPLC)
Biological Activity for ISX 9
ISX 9 is a neurogenic agent. Mediates neuroD reporter gene induction via activation of Ca2+ influx; increases expression of neurogenic differentiation 1 (NeuroD1) transcription factor. Induces neuronal differentiation in human cortical neuronal cells (HCN), adult mouse whole brain (MWB) and subventricular zone (SVZ) progenitors. ISX 9 is also shown to induce cardiomyogenic differentiation of Notch-activated epicardium-derived cells in vitro. When used in combination with other small molecules, ISX 9 directs differentiation of pancreatic progenitors towards β cells.
ISX 9 synthesized to Ancillary Material Grade also available.
For more information about how ISX 9 may be used, see our protocol: Transdifferentiating Fibroblasts into Neurons.
