Isoxazole 9 (Isx-9) is a synthetic promotor of adult neurogenesis by triggering neuronal differentiation of adult neural stem/precursor cells (NSPCs). Isoxazole 9 (Isx-9) activates multiple pathways including TGF-β induced epithelial–mesenchymal transition (EMT) signaling, canonical and non-canonical Wnt signaling at different stages of cardiac differentiation.

Mechanism of Action

In vitro	Isoxazole 9 (ISX-9) increases cell number and promotes cell differentiation in NSPCs, whereas it induces cell damage in OPCs. In outgrowth EPCs, this compound decreases tube formation without effect on early EPCs.
In vivo	In mice, isoxazole 9 (ISX-9) (20 mg/kg, i.p.) crosses the BBB and increases proliferation of neuroblasts and neurogenesis via Mef2-specific mechanisms in the hippocampal SGZ. This compound also increases differentiation and dendritic complexity of immature neurons and improves memory. In MWM, it improves spatial memory.
