In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
4.1mg/ml Taking the 1 mL working solution as an example, add 50 μL of 82 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.65mg/ml Taking the 1 mL working solution as an example, add 50 μL of 13 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. 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 HSF1A is a cell-permeable heat shock transcription factor 1 (HSF1) activator. HSF1A protects cells from stress-induced apoptosis, binds TRiC subunits and inhibits TRiC activity without perturbation of ATP hydrolysis.
In vitro

HSF1A, an HSF1 activator, alleviates DOX-induced cardiomyocyte apoptosis via suppression of the IGF-IIR apoptotic signaling pathway.[1]
In vivo

HSF1A enhances HSF1 activity, stabilizes HSF1 expression and minimizes Doxorubicin (DOX)-induced cardiac damage. WKY rats are challenged with DOX (accumulated dose: 30 mg/kgw), and DOX combined with HSF1A. Supplementation with HSF1A significantly elevates cardiac functions back to the levels of the control group. HSF1A has been shown to stimulate human HSF1 nuclear translocation, elevate protein chaperone expression and ameliorate protein misfolding and cell death in a neurodegenerative disease model. The echocardiographic results show that HSF1A also alleviates DOX-induced failures in cardiac function.

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    H9c2 cells, Neonatal rat ventricular myocytes (NRVMs)

  • Concentrations

    10 μM

  • Incubation Time

    24 h

  • Method

    After treatments of HSF1A for 24 h, H9c2 cells and NRVMs are fixed with a 4% paraformaldehyde solution for 30 min. Following a rinse with PBS, the samples are incubated first with phalloidin–rhodamine for 1 h and subsequently with the TUNEL reaction mixture, containing terminal deoxynucleotidyl transferase and Resorcinolphthalein isothiocyanate-dUTP.
