Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	5.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 100 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 make it clear; 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 1 95% Corn oil	0.35mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 7 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

IKE(Imidazole ketone erastin) is a potent, selective, and metabolically stable system xc– inhibitor and inducer of ferroptosis.

Targets

Ferroptosis ^[1]

system xc– ^[1]

In vitro

Imidazole ketone erastin (IKE) is an erastin analog with nanomolar potency, high metabolic stability, and intermediate water solubility. Its treatment potently reduces DLBCL cell number^[1].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines DLBCL cell line Concentrations 0-100 μM Incubation Time 24 h Method DLBCL cells are plated at 10,000 cells per well in white 384-well plates (32 μL per well) in technical duplicates and incubated overnight. The cells are then treated with 8 μL medium containing a two-fold dilution series of vehicle (DMSO), IKE (starting from 100 μM) with or without Fer-1 (starting from 200 μM). After 24 h incubation, 40 μL of 50% CellTiter-Glo / 50% cell culture medium is added to each well and incubated at room temperature with shaking for 15 min. Luminescence is measured. All cell viability data are normalized to the DMSO vehicle condition. Experiments are performed three independent times with different passages for each cell line. From these data, dose-response curves and IC50 values are computed.
