Product Description

Erastin is a cell-permeable small molecule and potent ferroptosis activator by acting on mitochondrial VDAC with potential antineoplastic activity. It exhibits selectivity for tumor cells bearing oncogenic RAS and shows high in vivo antitumor efficacy in mice with HT-29 xenograft. Erastin is an antitumor agent selective for tumor cells bearing oncogenic RAS (i.e. HRAS, KRAS). Ferroptosis is a unique iron-dependent form of nonapoptotic cell death. It is triggered by oncogenic RAS-selective lethal small molecule erastin. Acitvation of ferroptosis lead to nonapoptotic destruction of cancer cells.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
Ferroptosis in ectopic endometrial stromal cells (EESC) is triggered by erematin (10 μM; 24 hours), and at 9 hours, total ROS levels rise [1]. In EESC cells, erythrin can reduce the length of mitochondria and raise their membrane density [1]. Iron-related proteins, including FPN (iron export protein), have lower levels of mRNA expression in EESCs when treated with erythrin (10 μM) for nine hours. On the other hand, overexpression of FPN can considerably prevent Erastin-induced ferroptosis of EESCs [1]. In HT-29 colorectal cancer cells, erematin (10 μM; 24 hours) causes the opening of the mitochondrial permeability transition pore (mPTP) [2]. The proliferation of HT-29 colorectal cancer cells is greatly inhibited by eratin (30 μM; 72 hours) [2]. The genes that control iron metabolism or mitochondrial fatty acid metabolism are involved in the biological mechanism by which erythropoidin triggers ferroptosis. comprises tetrapeptide repeat domain 35, citrate synthase, ATP synthase F0 complex subunit C3, ribosomal protein L8, iron response element binding protein 2 (IREB2), and acyl-CoA synthetase family member 2 (ACSF2)[3].
ln Vivo
Ferroptosis-induced animal models can be created with erastibin. In a mouse model of endometriosis, Erastin (40 mg/kg; i.p.; every 3 days for 2 weeks) inhibits endometriotic implantation, indicating that Erastin promotes regression of ectopic lesions by inducing ferroptosis [1]. In SCID mice, eratin (10 mg/kg, 30 mg/kg; intraperitoneally; once daily for 4 weeks) suppresses the growth of HT-29 xenografts, with 30 mg/kg showing the greatest activity [2].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)

  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
