Cat.No. 4439 - ISX 9 | C11H10N2O2S | CAS No. 832115-62-5
Description: Neurogenic agent; induces neuronal differentiation of SVZ progenitors and also induces cardiomyogenic differentiation
Chemical Name: N-Cyclopropyl-5-(2-thienyl)-3-isoxazolecarboxamide
Purity: ≥99% (HPLC)

Biological Activity

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. Also shown to induce cardiomyogenic differentiation of Notch-activated epicardium-derived cells in vitro.

Compound Libraries

ISX 9 is also offered as part of the Tocriscreen Plus and Tocriscreen Stem Cell Toolbox. Find out more about compound libraries available from Tocris.
