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
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].
Cell Research	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.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
