Solubility (25°C)* In vitro DMSO 47 mg/mL (200.62 mM)
Ethanol 13 mg/mL (55.49 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 55%PEG300 40%ddH2O
10.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 200 mg/ml clarified DMSO stock solution to 550 μL of PEG 300, mix evenly to clarify it; then continue to add 400 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description 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.
In vitro In NSPCs, isoxazole 9 increases cell number, and promotes cell differentiation. In OPCs, isoxazole 9 induces cell damage. In outgrowth EPCs, isoxazole 9 decreases tube formation without effect on early EPCs. [1]
In vivo In mice, isoxazole 9 (20 mg/kg, i.p.) crosses the BBB and increases proliferation of neuroblasts and neurogenesis via Mef2-specific mechanisms in the hippocampal SGZ. Isoxazole 9 (20 mg/kg, i.p.) also increases differentiation and dendritic complexity of immature neurons and improves memory. In MWM, isoxazole 9 improves spatial memory. [2]

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    NSPCs, OPCs, early EPCs, and outgrowth EPCs

  • Concentrations

    ~50 μM

  • Incubation Time

    48 h

  • Method

    Cells are treated with different concentrations of Isx-9 (0, 6.25, 12.5, 25, or 50 μM), and 2 days later, cell numbers are counted in a blinded manner to evaluate the effects of Isx-9 on the proliferation/survival of four types of progenitor/precursor cells.
Animal Study:[2]
  • Animal Models

    Transgenic Nkx2.5-luciferase reporter mice

  • Dosages

    20 mg/kg

  • Administration

    i.p.
