ISX9 (832115-62-5) promotes neurogenesis in vivo enhancing the proliferation and differentiation of hippocampal subgranular zone neuroblasts and enhances memory.1?Induces robust neuronal differentiation in adult neural stem cells.2?Increases insulin production by pancreatic β cells.3?ISX9 blocks malignant astrocyte proliferation, downregulates their astrocyte character, induces reentry into the cell cycle and upregulates neuronal gene expression.4 Induces sensory neurons from neuroepithelial stem cells.5 Potentiates cell proliferation and neuronal commitment in the rat dentate gyrus.6
N-Cyclopropyl-5-(thiophen-2-yl)isoxazole-3-carboxamide was shown to exhibit regulatory effects towards the expression of pH sensing G protein-coupled receptor-68 and is now a new drug target for ischemic heart disease.
ChEBI: N-cyclopropyl-5-thiophen-2-yl-3-isoxazolecarboxamide is a heteroarene and an aromatic amide.
A cell-permeable isoxazole compound that selectively induces robust neuronal differentiation (Effective concentration = 20 μM) in various stem/progenitor cells. Induces insulin expression, and activates ERK signaling and histone acetylation in MIN6 pancreatic β cells. The underlying excitation-neurogenesis signaling is comprised of, at least in part, an initial NMDA receptor- and L-type chanenels-mediated Ca2+ influx, followed by an activation of CaMKII, phosphorylation/nuclear export of the MEF2 repressor HDAC5, the subsequent de-repression of MEF2, and the eventual activation of the HDAC-MEF2 epigenetic/transcriptional regulatory network.
