Cell experiment [1]: | |
Cell lines |
DLBCL cells |
Preparation Method |
DLBCL cells were plated at 10,000 cells per well in white 384-well plates in technical duplicates and incubated overnight. The cells were then treated with 8 µL medium containing a two-fold dilution series of vehicle , Imidazole Ketone Erastin (0.1 nM-100 µM ) with or without Fer-1. After 24 h incubation, 40 µL of 50% Cell Titer-Glo 50% cell culture medium was added to each well and incubated at room temperature with shaking for 15 min. |
Reaction Conditions |
0.1 nM-100 µM; 24 h |
Applications |
Imidazole ketone erastin (0.1nM-100µM;24h) potently reduces DLBCL cell number by lipid peroxidation and ferroptosis. |
Animal experiment [2]: | |
Animal models |
Male NCG mice |
Preparation Method |
NCG mice, 6-weeks old, were injected with 10 million SUDHL0-6 cells subcutaneously. The mice were treated after the tumor size reached 100 mm3. Mice were separated randomly into treatment groups and dosed with 23 mg/kg Imidazole Ketone Erastin , 40 mg/kg Imidazole Ketone Erastin , 23 mg/kg Imidazole Ketone Erastin PEG-PLGA nanoparticles , vehicle 1, and vehicle 2 once daily by IP for 14 days. |
Dosage form |
23, 40 mg/kg/d ; 14 days ; i.p. |
Applications |
Imidazole Ketone Erastin inhibited tumor growth in a diffuse large B cell lymphoma mouse model, caused a significant decrease in tumor growth and weight loss starting from day 9. |

Imidazole Ketone Erastin is an effective and metabolically stable system xc- inhibitor and ferroptosis inducer. Ferroptosis is a regulated form of cell death that can be induced by inhibiting the cystine-glutamate antiporter system xc- [1].
In vitro, Imidazole Ketone Erastin (0.1 nM-100 µM; 24 h) effectively reduces the number of DLBCL cells by inducing lipid peroxidation and ferroptosis, with 18 DLBCL cell lines displaying varying sensitivities to the inhibition by Imidazole Ketone Erastin [1]. Imidazole Ketone Erastin (1-250 nM; 24 h) depletes reduced glutathione in a dose-dependent manner, with an IC50 of 34 nM in SUDHL 6 cells, and also increases lipid ROS [1].
In vivo, Imidazole Ketone Erastin (23, 40 mg/kg/d; i.p.) inhibits tumor growth in a mouse model of diffuse large B cell lymphoma, leading to a significant reduction in tumor growth and body weight loss starting from day 9 [1]. Imidazole Ketone Erastin (40 mg/kg; i.p.) administered every other day for 22 days to mice with a model of chronic arthritis significantly alleviates symptoms of synovitis and promotes the rapid resolution of inflammation [2].

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
