S3QEL 2 is a selective inhibitor of superoxide production from the outer Q-binding site of mitochondrial respiratory complex site III (IIIQo) without altering oxidative phosphorylation. Site IIIQo is the primary source of mitochondrial reactive oxygen species (ROS) and has been implicated in a broad range of ROS-mediated signaling and pathology. S3QEL 2 lowered HIF-1α induction, protected against ROS-induced, JNK-mediated cell stress in pancreatic beta-cells, and decreased the oxidative stress-induced apoptosis that limits the yield of functional β-cells from intact islets.
S3QEL 2, a cell permeable substituted allopurinol, is also known as 1-(3,4-Dimethylphenyl)-N,N-dipropyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine.

Ferroptosis is a type of iron-dependent, non-apoptotic cell death, which is typically induced by cysteine starvation or by the inhibition of glutathione peroxidase 4 (GPX4) activity with the accompanying elevation in lipid peroxidation product levels. Despite the central role of

Reactive Oxygen Species (ROS) are highly reactive molecules that can induce oxidative stress. For instance, the oxidative burst of immune cells is well known for its ability to inhibit the growth of invading pathogens. However, ROS also mediate redox signalling
