Reactive Oxygen Species (ROS)
Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

MDH1-IN-2
0 ImagesMDH1-IN-2 (Compound 7c) is a selective MDH1 inhibitor, with IC50 values of 2.27 and 27.47 μM for MDH1 and MDH2, respectively. MDH1-IN-2 can reduce the generation of ROS by inhibiting the conversion of 2-Ketoglutaric acid (HY-W013636) to α-Hydroxyglutaric acid (HY-113038B) mediated by MDH1, thereby suppressing 2-Ketoglutaric acid (HY-W013636)-induced ferroptosis.

Quinolinic acid-d3
0 ImagesQuinolinic acid-d3 is the deuterium labeled Quinolinic acid. Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

Solasonine
0 ImagesSolasonine is a ferroptosis inducer which can be isolated from Solanum melongena that has anti-infection, anti-cancer, and neurogenesis promoting properties. Solasonine promotes ferroptosis of HCC cells via destruction of the glutathione redox system induced by inhibiting GPX4, and can be used for cancer research.

Urolithin C
0 ImagesUrolithin C, a gut-microbial metabolite of Ellagic acid, is a glucose-dependent activator of insulin secretion. Urolithin C is a L-type Ca2+ channel opener and enhances Ca2+ influx. Urolithin C induces cell apoptosis through a mitochondria-mediated pathway and also stimulates reactive oxygen species (ROS) formation.

D-α-Hydroxyglutaric acid
0 ImagesSynonyms: (R)-2-Hydroxyglutarate; (R)-2-Hydroxyglutaric acid; (R)-2-Hydroxypentanedioic acidD-α-Hydroxyglutaric acid ((R)-2-Hydroxyglutarate) is the principal metabolite accumulating in neurometabolic disease D-2-hydroxyglutaric aciduria. D-α-Hydroxyglutaric acid is a weak competitive antagonist of α-ketoglutarate (α-KG) and inhibits multiple α-KG-dependent dioxygenases with a Ki of 10.87 mM. D-α-Hydroxyglutaric acid increases reactive oxygen species (ROS) production. D-α-Hydroxyglutaric acid binds and inhibits ATP synthase and inhibits mTOR signaling.

Miglitol
0 ImagesSynonyms: BAY1099; BAY-m1099Miglitol (BAY-m1099) is an orally active antidiabetic compound that inhibits the breakdown of glycoconjugates into glucose. Miglitol inhibits glycoside hydrolase enzymes called α-glucosidases. Miglitol inhibits oxidative stress-induced apoptosis and mitochondrial ROS over-production in endothelial cells by enhancement of AMP-activated protein kinase. Dietary supplementation with Miglitol from pre-onset stage in OLETF rats delays the onset and development of diabetes and preserves the insulin secretory function of pancreatic islets.
