Ferroptosis-IN-21
Based on 1 Customer Validation
Ferroptosis-IN-21 is a ferroptosis inhibitor that protects against renal I/R injury by suppressing ferroptosis and directly scavenging peroxyl radicals. Ferroptosis-IN-21 displays broad-spectrum anti-ferroptotic efficacy across multiple inducers in renal tubular epithelial cells, with nanomolar potency and robust suppression of lipid Reactive Oxygen Species (ROS). Ferroptosis-IN-21 significantly ameliorates renal I/R injury in mice, reducing histological damage, functional impairment, and inflammatory cytokine expression, while decreasing lipid peroxidation biomarkers such as 4-hydroxynonenal. Ferroptosis-IN-12 can be used for research in the field of ferroptosis-targeted drug development.

Biological Activity
Ferroptosis-IN-21 (compound 6) (0.01-10 μM, 24 h) exhibits nanomolar cytoprotective activity (EC50 = 61.7 nM) and completely reverses cell death at 200 nM in HT-1080 cells, and dose-dependently protects Human Kidney Cortex epithelial cells (HKC) and Human Kidney 2 (HK-2) cells from ferroptosis induced by RSL-3 (HY-100218A) and FIN-56, confirming its broad-spectrum efficacy[1].
Ferroptosis-IN-21 (50-500 nM, 24 h) significantly suppresses RSL-3-induced lipid ROS accumulation and MDA elevation, and has no effect on GPX4 protein levels[1].
Ferroptosis-IN-21 (10 µM) does not chelate iron ions, ruling out an iron-chelating mechanism[1].
Ferroptosis-IN-21 (1-80 µM, 30 min) exhibits potent direct radical scavenging activity in Cell-free DPPH assay[1].

Animal Model:Male C57BL/6 mice (8-12 weeks old) subjected to bilateral renal ischemia (40 min) and reperfusion (24 h) [1]
-
Dosage:5 and 10 mg/kg
-
Administration:i.p., 24 hours and 1 hour pre-treatment
-
Result:Reduced the serum creatinine, blood urea nitrogen (BUN), and kidney coefficient relative to the I/R group.
Conferred substantial structural protection, with the 10 mg/kg dose yielding the most notable histological preservation.
Markedly suppressed mRNA expression levels of KIM-1 and NGAL in a dose-dependent manner.
Significantly reduced the expression of TNF-α, IL1-β, IL-6, and MCP-1 upregulated by I/R insult in a dose-dependent manner, indicating an anti-inflammatory effect.
Markedly reduced I/R-induced 4-HNE accumulation.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
