Biological Activity

Description
Liproxstatin-1 acts as a powerful inhibitor of ferroptosis, blocking ferroptotic cell death with an IC50 value of 22 nM[1].
Target
  • Ferroptosis

    ferroptosis, IC50:22 nM

In Vitro:

Cell Line
Concentration Treated Time Description References
MDA-LM2 1 µM 1 h To evaluate the inhibitory effect of Liproxstatin-1 on TBHP-induced cell death PMC10212767
NCI-H522 cells 0.25 μM 3 days Liproxstatin-1, as a selective ferroptosis inhibitor, was used to rescue cell death induced by cytotoxic analogs. All analogs of the amide series showed significant cytotoxicity in NCI-H522 cells, which was completely rescued in the presence of Liproxstatin-1. PMC10408038
HIEC (human normal small intestinal epithelial cell line) 1 μM 24 h Liproxstatin-1 significantly reversed hypoxia-induced cell death in HIEC, indicating that the mode of cell death induced by hypoxia was predominantly ferroptosis. PMC11321022
NGEC (human normal gastric epithelial cell line) 1 μM 24 h Liproxstatin-1 significantly reversed hypoxia-induced cell death in NGEC, indicating that the mode of cell death induced by hypoxia was predominantly ferroptosis. PMC11321022
A375P cells 2 μM 24 h To measure lipid peroxidation, results showed that Liproxstatin-1 significantly reversed DC661-induced lipid peroxidation PMC10104903
A375P cells 2 μM 24 h To measure lipid peroxidation, Liproxstatin-1 significantly reversed DC661-induced lipid peroxidation PMC10104903
MOLP-8 1 µM 10 h Inhibited ferroptosis in LILRB1-KD MM cells PMC11233649
ARP-1 1 µM 10 h Inhibited ferroptosis in LILRB1-KD MM cells PMC11233649
HK-2 cells 0.5 µM 24 h To investigate the effect of Liproxstatin-1 on oxalate-induced ferroptosis in HK-2 cells, results showed that Liproxstatin-1 inhibited oxalate-induced ferroptosis. PMC10763321
Human melanoma cells 1 μM 24 h To test the effect of Liproxstatin-1 on ferroptosis in melanoma cells, the results showed that Liproxstatin-1 blocked the effect of Erastin on cell count reduction. PMC7484468

Administration Dosage Frequency Description References
Mice MM model Intraperitoneal injection 15 mg/kg Daily Reversed the inhibition of MM progression induced by LILRB1 deficiency PMC11233649
Mice Kidney stone mouse model Injection 10 mg/kg 15 days To investigate the protective effect of Liproxstatin-1 on CaOx-induced kidney injury, results showed that Liproxstatin-1 alleviated CaOx-induced kidney injury. PMC10763321
Mice NSG and C57BL mice Intraperitoneal injection 20 mg/kg Daily injections until the end of the experiment To test the effect of Liproxstatin-1 on the survival of melanoma cells in the blood, the results showed that Liprox pre-treatment significantly increased metastatic disease burden in most efficiently metastasizing melanomas. PMC7484468
BALB/c nude mice Footpad implantation nude mouse model Intraperitoneal injection 10 mg/kg Once daily for 20 days Liproxstatin-1, as a ferroptosis inhibitor, was used to study its effect on tumor growth and metastasis. The results showed that Liproxstatin-1 slightly promoted tumor growth but had no significant effect on lymph node metastasis. PMC9860034
